Standard Costs and Operating Performance Measures
Chapter 12
McGraw-Hill Education (Asia) Garrison, Noreen, Brewer, Cheng & YuenMcGraw-Hill/Irwin Slide 2
Standard Costs
Standards are benchmarks or “norms” formeasuring 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 Standards
Six Sigma advocates have sought toeliminate 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.

The rate is the variable portion of the
predetermined overhead rate.
QuantityStandards
The quantity is the activity in the
allocation base for predetermined overhead.

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.

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.

Material Variances: The Line-by-line Method
AQ x AP = 210 x AP = 1,029(21) F Price variance
AQ x SP = 210 x 5 = 1,05050 U Quantity variance
SQ x SP = (2000 x 0.1) x 5 = 1,00029 U Total Variance
SQ = (Aouput x standard quantity for production) = standard quantity allowed for the actual output
Calculation of Actual Purchase Price (AP) per unit can be done but is not necessary because AP will not be used in subsequent calculation and the total actual purchase cost in total is sufficient for the variance calculation.

Material Variances:Using the Factored Equations
Materials price varianceMPV = AQ (AP - SP)
= 210 kgs ($4.90/kg - $5.00/kg)
= 210 kgs (-$0.10/kg)
= $21 F
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)

Isolation of Material Variances
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.

Material Variances
Hanson 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.

Variable Manufacturing Overhead Variances: Using Factored Equations
Variable manufacturing overhead rate varianceVMRV = AH (AR - SR)
= 2,500 hours ($4.20 per hour – $4.00 per hour)
= 2,500 hours ($0.20 per hour)
= $500 unfavorable
Variable manufacturing overhead efficiency varianceVMEV = SR (AH - SH)
= $4.00 per hour (2,500 hours – 2,400 hours)
= $4.00 per hour (100 hours)
= $400 unfavorable

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.
