Standard CostsStandards are benchmarks or “norms” for

measuring performance. In managerial accounting,two types of standards are commonly used.

Quantity standardsspecify how much of aninput should be used to

make a product orprovide a service.

Price standardsspecify how muchshould be paid foreach unit of the

input.

Examples: Firestone, Sears, McDonald’s, hospitals, construction, and manufacturing companies.

Setting Standard CostsShould we use

ideal standards that require employees towork at 100 percent

peak efficiency?

Engineer Managerial Accountant

I recommend using practical standards that are currently

attainable with reasonable and efficient effort.

Learning Objective 1

Explain how direct materials standards and

direct laborstandards are set.

9-7

Setting Direct Material Standards

Summarized in a Bill of Materials.

Final, deliveredcost of materials,net of discounts.

StandardQuantity Per Unit

9-8

Setting StandardsSix Sigma advocates have sought to

eliminate all defects and waste, rather than continually build them into standards.

As a result allowances for waste andspoilage that are built into standards

should be reduced over time.

9-9

Setting Direct Labor Standards

Standard RatePer Hour

Often a singlerate is used that reflectsthe mix of wages earned.

Standard HoursPer Unit

Use time and motion studies for

each labor operation.

9-10

Setting Variable Manufacturing Overhead Standards

PriceStandard

The rate is the variable portion of the

predetermined overhead rate.

QuantityStandard

The quantity is the activity in the

allocation base for predetermined overhead.

9-11

Standard Cost Card

A standard cost card for one unit of product might look like this:

(1) (1) x (2)Standard Standard StandardQuantity Price Cost

Inputs or Hours or Rate per Unit

Direct materials 3.0 lbs. 4.00$ per lb. 12.00$ Direct labor 2.5 hours 14.00 per hour 35.00 Variable mfg. overhead 2.5 hours 3.00 per hour 7.50 Total standard unit cost 54.50$

9-12

Price and Quantity StandardsPrice and quantity standards are

determined separately for two reasons:

The purchasing manager is responsible for raw material purchase prices and the production manager is responsible for the quantity of raw material used.

The purchasing manager is responsible for raw material purchase prices and the production manager is responsible for the quantity of raw material used.

The buying and using activities occur at different times. Raw material purchases may be held in inventory for a period of time before being used in production.

Glacier Peak Outfitters has the following direct material standard for the fiberfill in its mountain

parka.

0.1 kg. of fiberfill per parka at $5.00 per kg.

Last month 210 kgs. of fiberfill were purchased and used to make 2,000 parkas. The material cost a total

of $1,029.

Let’s calculate the material price and quantity variances.

Materials quantity varianceMQV = SP (AQ - SQ) = $5.00/kg (210 kgs-(0.1 kg/parka 2,000

parkas)) = $5.00/kg (210 kgs - 200 kgs) = $5.00/kg (10 kgs) = $50 U

Direct Materials Variances – Points of Clarification

I need the price variancesooner so that I can better

identify purchasing problems.

You accountants just don’tunderstand the problems thatpurchasing managers have.

I’ll start computingthe price variancewhen material is

purchased rather than when it’s used.

9-28

Direct Materials Variances – Points of Clarification

Glacier purchased and used 210 kilograms.

How are the variances computed if the amount purchased differs from

the amount used?

The price variance is computed on the entire

quantity purchased.

The quantity variance is computed only on

the quantity used.

I am not responsible for this unfavorable material

quantity variance.

You purchased cheapmaterial, so my peoplehad to use more of it.

Your poor scheduling sometimes requires me to

rush order material at a higher price, causing

unfavorable price variances.

Direct Labor Variances – Points of Clarification

Production Manager

Production managers areusually held accountable

for labor variancesbecause they can

influence the:

Mix of skill levelsassigned to work tasks.

Level of employee motivation.

Quality of production supervision.

Quality of training provided to employees.

9-47

I am not responsible for the unfavorable labor

efficiency variance!

You purchased cheapmaterial, so it took more

time to process it.

I think it took more time to process the

materials because the Maintenance

Department has poorly maintained your

equipment.

ColaCo: Reconciling Overhead Variances and Underapplied or Overapplied Overhead

In a standardcost system:

Unfavorablevariances are equivalent

to underapplied overhead.

Favorablevariances are equivalentto overapplied overhead.

The sum of the overhead variancesequals the under- or overapplied

overhead cost for the period.

Computing the Variable Overhead Variances

Variable manufacturing overhead rate varianceVMRV = (AH × AR) – (AH × SR) = $100,000 – (88,000 hours × $1.00 per hour) = $12,000 unfavorable

Glacier Peak Outfitters - Revisited

We will use information from the Glacier Peak Outfittersexample presented earlier in the chapter to illustrate journal

entries for standard cost variances. Recall the following:

Material

AQ × AP = $1,029AQ × SP = $1,050SQ × SP = $1,000MPV = $21 FMQV = $50 U

Material

AQ × AP = $1,029AQ × SP = $1,050SQ × SP = $1,000MPV = $21 FMQV = $50 U

Labor

AH × AR = $26,250AH × SR = $25,000SH × SR = $24,000LRV = $1,250 ULEV = $1,000 U

Labor

AH × AR = $26,250AH × SR = $25,000SH × SR = $24,000LRV = $1,250 ULEV = $1,000 U

Now, let’s prepare the entries to recordthe labor and material variances.

Cost Flows in a Standard Cost System

Inventories are recorded at standard cost.

Variances are recorded as follows: Favorable variances are credits, representing

savings in production costs. Unfavorable variances are debits, representing

excess production costs.

Standard cost variances are usually closed out to cost of goods sold. Unfavorable variances increase cost of goods sold. Favorable variances decrease cost of goods sold.
