Executive Summary
Leasing and purchasing equipment forms some of the expenses on the capital budget hence,
affects the net profit of a company. When deciding whether to lease or purchase equipment it
is essential to understand the cash flows associated with each option and the effects of certain
parameters on the cash flows in order to select the option that will give the highest return to
the investment. In this study the net present value (NPV) is used to decide whether to lease or
purchase equipment, with the help of spreadsheet models that represent the cash flows
associated with each option. Then the effect of inflation rates, project life, interest rates, loan
payback period and percentage equity used to purchase the asset on the NPVs of the
spreadsheet models is determined using sensitivity analysis.

CHAPTER 1: Introduction and Background
1.1 Background and Problem Statement Prior to the 1950s only land and buildings were leased. Today, however almost any fixed
asset can be leased. For example about 50% of all new commercial aircraft sold is purchase
by aircraft leasing companies (Brigham et al., 1999).
At times companies make the decision to buy or lease equipment while not taking into
account all the factors that will have a positive or negative effect on the cash flow associated
with the decision made. This could be due to the fact that the management of a trading entity
may not be aware of the long term impact that acquiring an asset through leasing or buying
has on the capital budget of the company.
Most published literature that discusses the decision to lease or purchase equipment only
addresses the matter from a certain perspective and hence leaves out other factors that are
relevant to management faced with the task of deciding to lease or purchase equipment. For
example some publications present mathematical models that can be used to decide whether
to lease or purchase equipment but leaves out the detailed theoretical explanations of the cash
flows incorporated into the formulas of the models and the effect that these cash flows will
have on the capital budget of the company, which is what management is interested in. These
models can prove to be of little help since they can be difficult to understand and implement
and require extensive mathematical knowledge to solve them.
There is a great need for a comprehensive analysis of leasing and purchasing equipment and a
simplified approach of deciding whether to lease or purchase equipment that will be relevant
and easy to implement for all companies.
1.2 Project Aim The aim of this study is to provide a detailed research on the following:
The cash flows associated with leasing and purchasing equipment.
The factors that companies should consider when contemplating to lease or purchase
equipment.
The effect that leasing and purchasing equipment has on a company’s capital budget.
Then finally provide a structured approach that can be followed by any company when
deciding to lease or purchase equipment.

1.3 Project Scope To conduct the study the following problem solving approach will be used (Tarquin, 2008:8)
Step 1: understand the problem.
Step 2: Collect information.
Step 3: Define feasible alternative solution and make realistic estimations.
Step 4: Identify criteria for decision making.
Step 5: Evaluate each alternative.
Step 6: Select the best alternative.
To accomplish the first two steps, an in depth study of the literature currently available about
buying and leasing equipment and how the capital budget is affected by leasing or purchasing
equipment. The effect that the size of the loan acquired to purchase the equipment, period to
pay back the loan, inflation rate and project life on the decision to purchase or lease
equipment.
With regards to step 3; the alternative solutions will be the different techniques of evaluating
capital investment decisions. Keep in mind that the solution in this case would be the best
suited technique to be used when deciding to lease or purchase equipment.
According to step 4, a decision making criteria must be selected for each technique
mentioned in step3.
In step 5 each decision making technique will be evaluated and compared against each other.
Lastly a conclusion will be reached on which technique is to be used when deciding to lease
or purchase equipment.

Chapter 2: Literature Review
2.1 Capital Budget A capital budget consists of an outline of planned long term investments on fixed assets.
Capital budgeting is the process of analyzing projects and deciding which ones to include in
the company’s capital budget. Assets included in the capital budget have the following
characteristics (du Toit et al., 2001):
The expected life of the asset is longer than one year.
They are not traded in the normal course of the firm’s business.
The equipment to be discussed in this study present the features or characteristics mentioned
above therefore they are recorded in the capital budget and can be referred to as capital
budget investments.
2.1.1 Importance of the capital budget The distribution of resources in the capital budget determines whether management will
be able to produce a minimum return on the investor’s money that the investor would
have received on an alternative investment. This factor determines whether investors keep
investing in the company or they take their investments elsewhere (Brigham et al.,2005).
From the capital budget potential investors and current investors can determine the firm’s
strategic direction.
The acquisition of assets or projects that the company decides to finance will affect the
company’ cash flow for a number of years still to come, that is why capital budgeting is
preceeded by a forecast of future expences and future income. A significant amount of
this forecast is done during the analysis of the cash flows associated with leasing or
purchasing equipment.
2.1.2 Influence of the capital structure on capital budget decisions
To acquire an asset buy leasing or purchasing a company needs capital. Capital structure
refers to the different sources of capital that a company uses, the fixed amount of capital
that the company gets from each source and the cost of each capital source. These
different sources of capital are referred to as capital components. According to Brigham
et al., (1999) the three major capital components are: common stock, preferred stock and
debt capital. Companies may choose to use only one of these sources of capital or a
combination of two sources or a combination of all three sources.
7
Common stock refers to the amount that shareholders have invested in the organisation
plus retained earnings, which is the amount earned from income generating activities
(Walter & Charles, 2008). Preferred stock is a hybrid of common stock and long-term
debt. Preferred stock can be referred to as long term debt because if it is used as capital to
acquire an asset then a fixed dividend must be paid to the preferred stockholders. It can
also be referred to as common stock because the dividend is not paid out to the preferred
stock holders unless the board of directors declare the dividend, as this is the case with
common stock (Walter & Charles, 2008). Debt capital refers to raising capital by
acquiring debt; it can be through a loan or issuing bonds. Each company ought to have an
optimal capital structure that is aimed at providing the highest possible economic value
added (EVA).
According to Brigham et al., (1999) the capital structure is used to determine the cost of
capital by using the weighted average cost of capital equation (WACC).
WACC = 𝒘𝒅𝒌𝒅 𝟏 − 𝑻 + 𝒘𝒑𝒔𝒌𝒑𝒔 + 𝒘𝒄𝒆𝒌𝒔 [𝟐. 𝟏]
wd, wps and wce are the weights used for debt, preferred and common equity respectively.
kd is the interest rate of the debt.
T is the marginal tax of the firm.
Kps is the preferred dividend divided by the net issuing price, 𝑘𝑝𝑠 = 𝐷𝑝𝑠
𝑃𝑛
Ks is the rate of return required by investors.
The weights for debt, preferred equity and common equity are determined by each
company on the company’s capital structure policy.
Capital structure enables management to determine beforehand the projects that will
require a minimum cost of capital. By considering the capital structure management can
determine the capital component that costs the most at that specific time, and then use less
of that capital component when financing new capital investments.
2.1.3 Influence of interest, tax and inflation rates on cost of capital
When interest rates in the economy increase the cost of debt capital will also increase
because bondholders and banks will require a higher interest rate. Higher interest rates
will also increase the cost of preferred equity capital. Variation in the tax rate will affect
the cost of capital equity. An increased tax rate will lead to a low cost of debt capital
according to the WACC equation (Brigham et al., 1999). An increase in inflation tends to
8
increase the required rates of return by the investors, this leads to a higher cost of capital
(du Toit et al., 2001).
2.2 Lease of Equipment
2.2.1 Typical lease agreement
Leasing is characterised by the separation of ownership of the asset and right of use of the
asset between the lessor and the lessee. The lessor owns the asset but the lessee has the right
to use the asset (du Toit et al., 2001). According to the Internal Revenue Service an
agreement is regarded as a lease agreement if the following requirements are met (Brigham
1999):
The period of leasing the asset (including renewals and extensions of the lease
agreement) should not exceed 80% of the estimated useful life of the asset. The
remaining useful life of the asset after the lease term must not be less than a year.
The residual value of the asset at the end of the lease term must at least equal 20% of
the value of the asset at the start of the lease period.
The lessee or any other party is not allowed to purchase the equipment at a price
determined at the start of the lease term.
A lease agreement usually contains the following information:
The duration of the lease contract.
The specific lease payments and the number of payments.
Conditions of renewal of the lease agreement.
Individual responsible for maintenance costs.
How the residual value will be incorporated in the cash flows.
The description of the leased assets.
2.2.2 Different types of leases available
Leasing takes place in four different forms, being, the operating lease, financial or capital
lease and a sale and sale back lease agreement (Brigham et al., 1999).
Operating lease
The lessor is required to maintain and service the leased equipment, the cost of
maintaining is built into the lease payment.
The lease payments are not sufficient for the lessor to cover the full capital
coat of the asset.
Operating lease agreements contain a cancellation clause which allows the
lessee to cancel the lease and return the asset before the end of the lease term.
9
Financial or capital lease
The lessor does not provide maintenance services.
The lease payments fully amortize the capital cost of the equipment.
The lease agreement is not cancellable, unless the asset is fully amortized.
Sale – and - Leaseback
A company that owns an asset sells the asset to another firm and
simultaneously executes an agreement to lease the equipment at specific terms
and period.
The seller gets the purchase price immediately from the buyer.
The seller still retains the use of the equipment.
2.2.3 Tax and leasing agreements
According to the Income Tax Act 1962, administered by the Commissioner of the South
African Revenue Services (SARS), tax payments and other expenditures incurred in the
production of income not of capital nature can be deducted from income for tax purposes.
These deductions grant tax savings for the lessee and are referred to as general deductions.
The tax savings are calculated in the following manner:
𝑻𝒂𝒙 𝒓𝒂𝒕𝒆 × 𝒍𝒆𝒂𝒔𝒆 𝒑𝒂𝒚𝒎𝒆𝒏𝒕 + (𝑶𝒕𝒉𝒆𝒓 𝒆𝒙𝒑𝒆𝒏𝒅𝒊𝒕𝒖𝒓𝒆𝒔 × 𝑻𝒂𝒙 𝒓𝒂𝒕𝒆) [2.2]
2.2.4 Influence of interest changes on a lease agreement
Interest rates influence the lease payments determined by the lessor on the lease agreement.
The internal rate of return (IRR) that will allow the net present value of the cash flows
experienced by the lessor equal to zero is the IRR that the lessor selects to determine the lease
payments.
The lessor determines the internal rate of return (IRR) required by considering the net
present value of the cash flows experienced while acquiring the asset and maintaining it.
These cash flows from the lessor perspective include: the net purchase price, maintenance
costs, tax on residual value and lease payment, depreciation and maintenance tax savings.
If the cost of capital (return required by the capital components) for acquiring and maintain
the asset was high, this will result in the lessor declaring a high IRR in order to pay back the
cost of capital and earn interest. This will result in high lease payments.
On the other hand if the return required by the capital components is relatively low, the lessor
will declare a lower IRR, hence the lease payments on the lease agreement will be lower
(Brigham et al., 1999).

2.3 Purchasing of equipment
2.3.1 Tax implications
According to the Legal and Policy division, South African Revenue Service (2009) all goods
purchased from a vendor value added tax (VAT) is paid as part of the purchase price. The
current vat rate is 14% is South Africa. Therefore when purchasing an asset, the VAT is
included in the purchase prize. Once the asset is purchased and put to use, the tax payer can
declare tax savings based on the operating expenses of the asset and depreciation expenses
(S.A Income tax Act section 6, 1962). If the asset is being resold at a market value that is
higher than the salvage value, a capital gains tax (CGT) is paid on the difference between the
two amounts (South African Income tax Act section 11, 1962).
2.3.2 Depreciation Depreciation refers to the reduction in the value of an asset (Tarquin, 2008). Depreciation
reduces the calculated net profit even though it is not a cash charge. A high depreciation leads
to a low tax bill (Brigham, 1999). Depreciation can be calculated using one of the following
methods
Straight line depreciation: The difference between the initial purchase price of the
asset and the estimated salvage value is divided by the economic life of the project to
find the annual depreciation amount (Tarquin, 2008). This method is mainly used for
stockholder reporting (or book purposes) (Brigham, 1999).
Modified accelerated cost recovery system (MACRS): This method consists of two
steps. In the first step the annual depreciation is determined by multiplying the initial
cost of the asset. In the second step, the book value in a particular year is determined
by subtracting the sum of annual depreciations (from previous years) from the initial
purchase price of the asset (Tarquin, 2008). This method is favoured when calculating
income tax since it yields high net profit reductions due to high depreciation
(Brigham, 1999).
2.4 Existing methodologies of making the lease-buy decision Various tools have been suggested to assist companies make the right choice to lease or
purchase equipment. The Vincil model also known as the Lease-Or-Borrow model is one of
these tools (Sartoris & Paul, 1973, 46:52). The Lease-Or-Borrow model compares the cost of
acquiring an asset through lease financing to the cost of acquiring the asset by purchasing the
asset using debt capital. The first step of the Lease-Or-Borrow model is to determine the net
present value of owning an asset, using the following formula
11
𝑵𝒆𝒕 𝒑𝒓𝒆𝒔𝒆𝒏𝒕 𝒗𝒂𝒍𝒖𝒆 𝒐𝒇 𝒑𝒖𝒓𝒄𝒉𝒂𝒔𝒆 = −𝑪 + 𝑫𝒏𝒕
(𝟏 + 𝒊)𝒏
𝒌
𝒏+𝟏
[𝟐. 𝟑]
Where C = Purchase Price
Dnt = Depreciation tax savings in year n
t = tax rate
i = Cost of capital
K = Life of the project
The second step is to determine the net present value of the lease payments, using the
following equation:
𝑵𝒆𝒕 𝑷𝒓𝒆𝒔𝒆𝒏𝒕 𝑽𝒂𝒍𝒖𝒆 𝒐𝒇 𝒍𝒆𝒂𝒔𝒆 = 𝑨𝒏𝒕
(𝟏+𝒊)𝒏𝒌𝒏=𝟏 −
𝑳𝒏
(𝟏+𝒓)𝒏𝒌𝒏=𝟏 [𝟐. 𝟒]
Where An = non interest portion of the lease payment in year n.
Ln = Lease payment in year n.
r = Basic interest rate.
k = Life of the asset.
i = Cost of capital
The highest positive NPV between the NPV of the lease and the NPV of purchasing indicates
the best alternative of acquiring the asset.
The Lease-Or-Buy model was developed by Johnson & Wilbur (1972). This model is similar
to the Lease-Or-Borrow model because it also develops the NPVs associate with leasing and
owning equipment. The difference between the two models is that the Lease-Or-Buy model
includes costs that are common when leasing or purchasing equipment, on the other hand the
Lease-Or-Borrow model omits these costs. Another significant difference between the two
models is that the Lease-Or-Buy model compares the costs of acquiring an asset through
leasing to the costs of acquiring through purchasing using own equity. On the other hand the
Lease-Or-Borrow model compares leasing to purchasing using debt capital.
The Lease-Or-Buy model consists of the following equations
𝑵𝑷𝑽 𝒑𝒖𝒓𝒄𝒉𝒂𝒔𝒆 = −𝑪 + 𝒕𝑫𝒏
(𝟏+𝒊)𝒏𝒌𝒏=𝟏 +
𝑹𝒏 (𝟏+𝒕)
(𝟏+𝒊)𝒏𝒌𝒏=𝟏 [2.5]
12
𝑵𝑷𝑽 𝒍𝒆𝒂𝒔𝒆 = 𝑹𝒏 +𝑶𝒏 (𝟏−𝒕)
(𝟏+𝒊)𝒏𝒌𝒏=𝟏 −
𝑳𝒏(𝟏−𝒕)
(𝟏+𝒓𝒕𝒊)𝒏𝒌𝒏=𝟏 [2.6]
Where Ri = Operating cash flow from the project in year i.
Oi = Operating costs that would occur under ownership of the asset but not under
the lease agreement.
rt = after tax interest rate.
Ln = Lease payment in year n.
Sartoris & Paul (173, 46:52) compared the two models (Lease-Or-Borrow and Lease-Or-
Buy) and reached a conclusion that Lease-Or-Borrow model leads to the correct decision
while Lease-Or-Buy model leads to an incorrect decision.
13
Chapter 3: Solution
3.1 Engineering methods and tools Leasing and purchasing equipment are both capital budget investments. Brigham et al.,(1999)
define the following capital budgeting decision rules that should be used to decide whether a
capital investment should be included in the capital budget or not.
Payback period – Compares the number of years required to recover the investment in
each project. The project with the lowest payback period is selected. It is applicable to
mutually exclusive projects.
𝑵𝒖𝒎𝒃𝒆𝒓 𝒐𝒇 𝒚𝒆𝒂𝒓𝒔 = 𝑰𝒏𝒊𝒕𝒊𝒂𝒍 𝑰𝒏𝒗𝒆𝒔𝒕𝒎𝒆𝒏𝒕
𝑨𝒏𝒏𝒖𝒂𝒍 𝒏𝒆𝒕 𝒄𝒂𝒔𝒉 𝒇𝒍𝒐𝒘 [𝟑. 𝟏]
Net Present Value (NPV) – NPV refers to the sum of the discounted cash flows at the
cost of capital. If NPV = 0, then the project is acceptable because the cash inflow is
sufficient to repay the initial investment at required rate of return of the capital. If
NPV > 0, then the project is still acceptable since the cash inflows will pay back the
cost of capital at a rate higher than the required cost of capital. If NPV < 0 then the
project is not acceptable since capital will be repaid at a rate that is less than the
required rate of return.
IRR (internal rate of return) –IRR is the rate of return required by a company to
ensures that the NPV of cash inflows is equal to zero. If the rate of return of any
project is less than the IRR of the company then that project is not included in the
capital budget.
MIRR (modified internal rate of return) – This decision making rule is an
improvement of the IRR. When using this rule, the terminal value (TV) has to be
defined. The TV is the future value of cash inflows. The MIRR is the discount rate
that ensures that the present value of cash outflows (PV cost) is equal to the present
value of the terminal value.
Profitability Index (Benefit cost ratio) – Shows the relative profitability of a project. A
project is acceptable if the Profitability index is greater than 1.0.
𝑷𝑰 = 𝑷𝑽 𝒃𝒆𝒏𝒆𝒇𝒊𝒕𝒔
𝑷𝑽 𝑪𝒐𝒔𝒕 [𝟑. 𝟐]
14
Brigham et al.,(1999) further mention that the net present value decision rule is the most
reliable and accurate decision rule.
3.2 Method selection and development To compare purchasing equipment and leasing equipment a cash flow analysis is used and the
cash flows are presented on spreadsheet models. This method is selected because it is easier
to prepare and understand spreadsheet models than to set up and understand mathematical
models. Hence, this method can be applied by any company. The NPV rule is used to analyse
the spreadsheets that represent the options of leasing and purchasing equipment in this study
because according to Brigham et al., (1999) this is the rule that managers prefer to use when
comparing projects. The reason for this is that the NPV value directly links to the economic
value added (EVA) to the company by a certain project and this is the information that
shareholders and investors are interested in. For example the NPV refers to the present value
of the EVA (Brigham et al., 1999). Brigham et al., (1999) further mentioned that well
managed companies cannot purchase equipment cash because cash is usually tied up in
assets.
To implement the method mentioned in the paragraph above, the following steps must be
followed.
I. State assumptions.
II. Collect the information that will be used to develop the spreadsheet models.
III. Present the expected cash flows on spreadsheet models.
IV. Determine the net present value in each of the spreadsheet models and decide on the
best alternative. The alternative with the highest positive NPV value will be accepted.
If the NPV value derived from the spread sheet calculations is negative, the option
represented by that spreadsheet is not accepted.
V. Determine how some inputs of the spreadsheet models affect the NPV, by changing
one input variable while keeping all other parameters and variables the same.
The final step is optional. It can be done if the company would like to know how certain
parameters will affect the cash flows associated with leasing and the cash flows associated
with purchasing. This step will be demonstrated in chapter 4.
To test this methodology, the steps listed above were used to decide whether to purchase or
lease an asset called the hydraulic mixer with scale (see figure 1). The relevant information
about the hydraulic mixer (e.g. purchase price, lease payments, operating costs) was made
available by the Turner and Morris Company located in Pretoria town Skinner Street. The
trade of the Turner and Morris Company is to sell and lease out fixed assets that are used in
the construction industry.
15
Figure 1: Hydraulic mixer
I. State assumptions
A loan is used to finance the purchase of the asset.
Payback period of the loan is 4 years.
The market value of the asset once it has been purchased decreases at a 10%
rate.
Life of the project is 15 years.
The minimum allowed rate of return (MARR) of the company is 15% since it
is normally stated to be higher than the rate of return charged by banks.
The lease presented on the spreadsheet model is an operating lease whereby
the lessor is responsible for the overhaul maintenance cost but the lessee is
responsible for the daily maintenance cost.

II. Collect relevant information
The data that is used to prepare the spread sheet models is presented on input tables
and calculations that precede each spread sheet model.
Steps III & IV are presented simultaneously on the spreadsheet models.
Below is the input table which represents data used to prepare the spreadsheet model that
represents the purchasing alternative.

The purchase price of this asset was provided by the Turner and Morris Company.
The loan used to purchase this equipment covers the entire purchase price. According
to Brigham et al., (1999) well managed companies cannot afford to purchase such
equipment cash since the company’s cash is tied up in fixed assets. The effect that the
percentage of own equity used to purchase the equipment is still to be investigated
further in this study.
The annuities and interest rates were calculated using discount factors published by
Blank Tarquin (2008).
The interest rate on the loan is 7% as this is the official rate of interest published by the
Legal and Policy division South African Revenue Services, March 2011.
18
The MARR before tax is 15% and it is based on the interest rate charged by the banks.
The MARR expected by management in companies is always higher that the interest
charged by the banks in order to declare a profit.
The depreciation used is straight line depreciation (Brigham et al., 1999:446)
The tax life of this equipment (cement mixer) is 3 years as stated on the Binding
General Ruling (Income Tax Act): NO.7 published 11 April 2011.
The Normal and Secondary tax rates are as published by the South African Revenue
Services.
To determine the market value at the end of the life of the project, it was assumed that
the market value decreases by 10% per year. The formula used is stated under
calculations.
The operating expenses and income are specific to the equipment being evaluated.
Below is the spreadsheet model that represents the option of purchasing the asset.

All cash flows are considered to be at the end of the year.
CFBT refers to cash flow before tax, and CFAT refers to cash flow after tax
The CFBT is the income generated by the equipment; in this case it is determined
under calculations.
The depreciation is calculated as stated on the calculations above.
The taxable income is calculated by subtracting the tax saving from depreciation and
expenditure and loses actually incurred during the year of assessment in the
production of income not of a capital nature (Income Tax Act, 1962) from the gross
income. In this case these expenses include the interest rate on the loan and operating
expenses.

After the life of the project (15 YEARS) the market value of the equipment is higher
than the book value (40 000). Capital gains tax is paid on the difference between the
market value and book value. The capital gains tax was assumed to be 28% of the
difference between the book value and the market value.
The NPV for the option to purchase equipment using a loan to finance it is positive,
which means that this option is acceptable.

Next, the option of leasing the asset is considered. Steps III & IV will be presented in the
same manner as in the option of purchasing the asset.

The lease payment is always paid at the beginning of the year. However, the first
lease payment can be paid along with the second payment at the beginning of the first
year.
Lease payments are considered to be an expense, hence, there are tax savings
experienced due to lease payments. Equation [3.4] was used to determine the tax
savings associated with the lease payment.
The value of operating expenses represents the expenses experienced daily, not the
overhaul expenses. This value was calculated in the calculations preceding the
spreadsheet model that represents the purchasing option. Equation [3.4] was used to
determine the tax savings associated with this expense.
The NPV is positive which makes this alternative acceptable.
When considering the NPV values on the spreadsheets we notice that the NPV on the
spreadsheet that represents purchasing is higher (R 1 414 270.19) than the NPV valve on the
spreadsheet that represents leasing (R 364 691.2973). These values suggest that the
purchasing alternative should be implemented. According to the NPV rule the alternative
with the highest positive NPV should be implemented. However, there is still another factor
to consider; the lives of the projects are not the same. In order to compare projects with
different lives the Equivalent Annual Annuity (EAA) value should be used (Brigham et al.,
1999). In each spreadsheet the EAA value is calculated right after the NPV value. The option
with the highest positive EAA value should be chosen. The EAA of the purchasing
calculations is R 1960682.556 and the EAA value of the leasing calculations is R
560173.40053. The purchasing option has a higher EAA value which means the asset should
be purchased rather than leased.

Chapter 4: Analysis
To accomplish step V sensitivity analysis was carried out on both spreadsheet models, to
determine how certain parameters affect the cash flows associated with leasing and
purchasing.
To determine how the percentage of own equity used to purchase the equipment affects the
NPV, different purchasing spreadsheet models were prepared where the amount of own
equity used to purchase the asset varied from 0% of the purchase price to 100% of the
purchase price. The spreadsheet model representing 0% own equity can be seen on table 2
and the spreadsheet models representing 25% to 100% own equity can be found in appendix
A. From figure 2 it can be seen that when the percentage of own equity used to finance the
purchase price increases, the NPV or profit that is expected from a project will decrease at a
constant rate. This shows that it would be best to purchase the asset using a loan rather than
use own equity (company’s money) to purchase the equipment.

Figure 3, below demonstrates how the NPV of a project changes if the duration of the project
decreases, when the asset is purchased using a loan. When the project life is varying the
market value of the asset at the end of the project life is affected, as well as the total income
generated since the number of operating years is varying. A project life of 15 years is the
normal scenario depicted on table 2, for further investigation the project life was reduced to 3
years (these spreadsheet models are shown in appendix B). On figure 3 it can be shown that
as the project life decreases from 15 years to 3 years the NPV or the return on the project
decreases. This is simply because the number of operating years has decreased hence less
profit is made.

The graph bellow (figure 4) depicts how the payback period of a loan used to purchase an
asset affects the NPV. The payback period is increased from 4 years to 8, 12 and 15 years
(spreadsheet models representing these payback periods are found in appendix C). The
change in the payback period affects the annual loan payment expense. When the payback
period of the loan is increased to 8 years the NPV also goes up. This is because the loan is
paid over a longer period and in smaller quantities which leads to high annual after tax cash

flows, resulting in an increased NPV. The same manner of reasoning applies if the payback
period is increased to 12 years; the NPV is increased due to higher annual after tax cash
flows. On the other hand if the payback period is equal to the life of the project (15 years),
this means the loan payments are spread over the entire life of the project, hence each annual
income is reduced by the loan payment. This has an adverse effect on the NPV, as seen on
figure 4 the NPV is drastically reduced if the payback period is equal to the life of the project.

Figure 5 below illustrates how inflation affects the NPV associated with purchasing
calculations. The spreadsheets that support the information presented in figure 5 are
presented in appendix D. Inflation is the annual increase in the amount of money required to
purchase the same amount of goods. If the inflation rate is incorporated into the spreadsheet
model that represents purchasing, this results in the operating expenses increasing yearly at
the rate of inflation. As the inflation rate increases from 5% to 6.6% to 9.6% the NPV value
decreases since the yearly operating expenses also increases. The current inflation in South
Africa at the moment is estimated to be 6.6%, this estimate was determined through a process
called inflation targeting (de Jager & Kahan, 2011).

Further analysis was also done on the leasing spreadsheet. To investigate the effect of
inflation on the NPV if an asset is leased multiple leasing spreadsheets were prepared with
varying inflation rates. These spreadsheets can be seen in appendix E. Figure 6 below

demonstrates the results. The change in the inflation rate affects only the operating expenses
if the asset was leased. The lease payment expense is not affected because these payments are
determined at the beginning of the lease period and cannot be adjusted for inflation during the
duration of the lease; the inflation rate is considered when the payments are first established
at the beginning of the lease period. In figure 6, as the inflation rate increases from 5%, to
6.6% and to 9.6% the NPV of the leasing spread sheet is decreasing, the reason for this is that
as inflation gets higher the operating expenses get even more expensive. Once the inflation
hits 9.6%, the NPV will be negative, which makes the leasing option unacceptable. If the
inflation rate were to actually rise to 9.6% the asset would not be leased since the NPV when
the asset is leased is negative, the asset would be purchased because as seen in figure 5 the
NPV is positive when the asset is purchased and the inflation rate is 9.6%.

Figure 8 shows how different project lives can affect the NPV if an asset is leased. The
relevant spreadsheets are in Appendix F. As the life of the project is decreased from 12 to 9
years the NPV is also decreasing. The reason is that when the project life gets shorter, there
are less operating years hence, less income. When the asset is leased the market value of the
asset at the end of the project duration does not affect the NPV of profit from the project.

To investigate how an increase in the interest rates would affect the profit expected from a
project whether the asset is leased or purchased further analysis was done on the leasing and
purchasing spreadsheet models and the results are show on figure 8 and figure 9. The
spreadsheet models supporting these graphs are on appendix G and appendix H respectively.

From figure 8 and 9 it is evident that when the interest rate increases the return that is
expected on a project decreases, whether the asset was leased or purchased. However the
slope of the graph on figure 8 is –R 382 466.44 and the slope of the graph in figure 9 is
-R 3.7041E-07, these values show that an increase in the interest rates will have a higher
effect on the profit of a project if the assets used on the project are purchased.

Chapter 5: Conclusions Based on the analysis in chapter 4, certain conclusions can be made regarding the effect that
inflation, interest rates and project life has on the decision to lease or purchase equipment.
The analysis also gave further insight on the effect of the loan payback period and the
percentage of equity used to purchase the equipment on the NPV if the asset is purchased.
The sensitivity analysis in figure 5 and 6 demonstrates the effect of different inflation
rates on the NPV when an asset is purchased and leased, respectively. The slope of
the graph in figure 5 is –12 277 451 and the slope of the graph in figure 6 is
-13 666 561, since figure 6 has a greater slope than figure 5 this implies that inflation
has a greater effect on the NPV if the asset is leased than when the asset is purchased.
Therefore, when an increase in inflation rate is expected it would be best to purchase
than to lease the asset.
The sensitivity analysis in figure 3 and in figure 7 show how the duration of the
project affects the NPV if the asset is purchased and leased respectively. The graph in
figure 3 has a slope of 37 551.576 and the slope of the graph in figure 7 is 27
743.55378. The slope of the sensitivity analysis graph (37 551.576) that reflects the
effect of the project life on the NPV when the asset is purchased is higher than the
slope of the sensitivity analysis graph (27 743.5) that shows the effect of the project
life when the asset leased. Therefore it can be concluded that it is best to lease the
asset than to purchase if the project life of the asset is less than 15 years.
Figure 8 demonstrates that as the interest rate increases the profit expected on a
project decreases at a rate of -382466 if the asset is purchased. On the other hand
figure 9 shows that as the interest rate increases the profit expected if the asset is
leased will decrease at a rate of -3.041E-07. From this it can be concluded that if a
rise in interest rates is anticipated it is best to lease the equipment.
If the decision to purchase the asset has been made the following conclusions can be made
based on figure 2 and 4.
Figure 2 shows the effect of using different values of own equity to purchase an asset
on the NPV when the asset is purchased. From this graph it can be concluded that it is
best to use a loan to purchase equipment since the return or profit of a project
decreases if own equity if used to finance the purchase price.
Figure 4 illustrates how different payback periods affect the NPV. Based on this
graph it can be concluded that as the loan payback period in increased the NPV will
also increase however, if the payback period is equal to the project life this leads to a
decrease in the NPV.
