B. Present Worth Analysis
• Principle – find the equivalent present worth of the economic merit of the project.
• How – compute the present worth of the total benefits (cash inflows) and the present worth of the total costs (cash outflows). Then, determine the net present worth by PW(i) = PW(i)cash inflows – PW(i)cash outflows
• Decision – Project can be justified if the net present worth is positive.
Procedure Principle: Compute the equivalent net surplus at n = 0 for a given interest rate of i. Decision Rule for Single Project Evaluation: Accept the project if the net surplus is positive. Decision Rule for Comparing Multiple Alternatives: Select the alternative with the largest net present worth.

Present Worth Amounts at Varying Interest Rates
Can you explain what $30,065 really means?1. Project Balance Concept2. Investment Pool Concept
1. Project Balance Concept• Suppose that a firm has no internal funds to
finance the project, so it will borrow the entire investment from a bank at an interest rate of 12%.
• Then any proceeds from the project will be used to pay off the bank loan.
• Then we should see if how much money would be left over at the end of the project period.
Calculating Project Balances
End of Year (n ) 0 1 2 3 4
Beginning Project Balance (76,000)$ (49,560)$ (18,147)$ 11,525$
Interest Charged (12%) (9,120)$ (5,947)$ (2,178)$ 1,383$
Payment (76,000)$ 35,560$ 37,360$ 31,850$ 34,400$
Ending Project Balance (76,000)$ (49,560)$ (18,147)$ 11,525$ 47,308$
PW(12%) $47,308( / ,12%,4) $30,065P F

2. Investment Pool Concept• Suppose a company has $76,000. It has two options:
(1)Take the money out and invest it in the project, or (2) leave the money in the pool and continue to earn 12% interest.
• If you take Option 1, any proceeds from the project will be returned to the investment pool and earn 12% interest yearly until the end of the project period.
• Let’s see what the consequences are for each option.
If $76,000 were left in the investment poolfor 4 years
$76,000(F/P,12%,4) $119,587
If $76,000 withdrawnfrom the investmentpool were invested inthe project

What Factors Should the Company Consider in Selecting a MARR in Project Evaluation?
• Cost of capital– The required return necessary to
make an investment project worthwhile.
– Viewed as the rate of return that a firm would receive if it invested its money someplace else with a similar risk
• Risk premium– The additional risk associated with
the project if you are dealing with a project with higher risk than normal project
