Standard Costs and

Operating Performance

Measures

Chapter 11

Standard Costs Standards are benchmarks or “norms” for

measuring performance. In managerial accounting,

two types of standards are commonly used.

Quantity standards

specify how much of an

input should be used to

make a product or

provide a service.

Price standards

specify how much

should be paid for

each unit of the

input.

Examples: Firestone, Sears, McDonald’s, hospitals,

construction and manufacturing companies.

Deviations from standards deemed significant

are brought to the attention of management, a

practice known as management by exception.

Setting Standard Costs Accountants, engineers, purchasing

agents, and production managers

combine efforts to set standards that encourage

efficient future operations.

Setting Standard Costs

Engineer

Should we use

ideal standards that

require employees to

work at 100 percent

peak efficiency?

Managerial Accountant

I recommend using practical

standards that are currently

attainable with reasonable

and efficient effort.

Price and Quantity Standards

Price 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.

Price Variance Quantity Variance


Actual Quantity Actual Quantity Standard Quantity × × × Actual Price Standard Price Standard Price





Actual quantity is the amount of direct

materials, direct labor, and variable

manufacturing overhead actually used.




Standard quantity is the standard quantity

allowed for the actual output of the period.




Actual price is the amount actually

paid for the input used.


Standard price is the amount that should

have been paid for the input used.




(AQ × AP) – (AQ × SP) (AQ × SP) – (SQ × SP)

AQ = Actual Quantity SP = Standard Price

AP = Actual Price SQ = Standard Quantity

Rate/Price Variance Usage/Quantity Variance


PV = AQ (AP - SP)

QV = SP (AQ - SQ)

Compute the direct

materials price and

quantity variances and

explain their significance.

Material Variances – An Example

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 @ $4.90/kgs

210 kgs. 210 kgs. 200 kgs.

Material Variances: Using the Factored Equations

Materials price variance

MPV = AQ (AP - SP)

= 210 kgs ($4.90/kg - $5.00/kg)

= 210 kgs (-$0.10/kg)

= $21 F

Materials quantity variance

MQV = 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

Isolation of Material Variances

I need the price variance sooner so that I can better

identify purchasing problems.

You accountants just don’t understand the problems that purchasing managers have.

I’ll start computing

the price variance

when material is

purchased rather

than when it’s used.

Material Variances

A Business purchased and used 1,700 pounds. 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.

Materials Price Variance Materials Quantity Variance

Production Manager Purchasing Manager

The standard price is used to compute the quantity variance

so that the production manager is not held responsible for

the purchasing manager’s performance.

The standard price is used to compute the quantity variance

so that the production manager is not held responsible for

the purchasing manager’s performance.

Responsibility for Material Variances

I am not responsible for this unfavorable material

quantity variance.

You purchased cheap material, so my people had to use more of it.

Your poor scheduling sometimes requires me to

rush order material at a higher price, causing

unfavorable price variances.

Responsibility for Labor

Variances

Production managers

are usually held

accountable

for labor variances

because they can

influence the:

Mix of skill levels

assigned to work tasks.

Level of employee

motivation.

Quality of production

supervision.

Quality of training

provided to employees.

I am not responsible for the unfavorable labor

efficiency variance!

You purchased cheap material, 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.
