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” 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

Accountants, engineers, purchasing
agents, and production managers
combine efforts to set standards that encourage
efficient future operations.

Setting Standard Costs
Should we use
ideal standards that
require employees to
work at 100 percent
peak efficiency?
Engineer Managerial Accountant
I recommend using practical
standards that are currently
attainable with reasonable
and efficient effort.

direct labor

Setting Standards
Six Sigma advocates have sought to
eliminate all defects and waste, rather than
continually build them into standards.
As a result allowances for waste and
spoilage that are built into standards
should be reduced over time.
McGraw-Hill Education (Asia) Garrison, Noreen, Brewer, Cheng & YuenMcGraw-Hill/Irwin Slide 10
Setting Direct Labor Standards
Rate
Standards
Often a single
rate is used that reflects
the mix of wages earned.
Time
Standards
Use time and
motion studies for
each labor operation.
McGraw-Hill Education (Asia) Garrison, Noreen, Brewer, Cheng & YuenMcGraw-Hill/Irwin Slide 11
Setting Variable Manufacturing Overhead

Standards
The rate is the
variable portion of the

Standards
The quantity is
the activity in the
allocation base for
predetermined overhead.

Standard Cost Card – Variable Production Cost
A standard cost card for one unit of
product might look like this:
A A x B
Standard Standard Standard
Quantity 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$

McGraw-Hill Education (Asia) Garrison, Noreen, Brewer, Cheng & YuenMcGraw-Hill/Irwin Slide 13
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 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.

quantity variances and
explain their significance.

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 – An Example
McGraw-Hill Education (Asia) Garrison, Noreen, Brewer, Cheng & YuenMcGraw-Hill/Irwin Slide 25
Material Variances: The Line-by-line Method
AQ x AP = 210 x AP = 1,029

SQ = (Aouput x standard quantity for production)

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 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 variancesooner so that I can better
identify purchasing problems.
You accountants just don’tunderstand the problems thatpurchasing managers have.
I’ll start computing
the price variance
when material is
purchased rather
than when it’s used.
McGraw-Hill Education (Asia) Garrison, Noreen, Brewer, Cheng & YuenMcGraw-Hill/Irwin Slide 31
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.

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.

I am not responsible forthis 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

Variable Manufacturing Overhead Variances: Using Factored Equations
Variable manufacturing overhead rate variance
VMRV = 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 variance
VMEV = SR (AH - SH)
= $4.00 per hour (2,500 hours – 2,400 hours)
= $4.00 per hour (100 hours)
= $400 unfavorable

Unfavorablevariances are equivalent
to underapplied overhead.
Favorablevariances are equivalentto overapplied overhead.
The sum of the overhead variances
equals the under- or overapplied
overhead cost for the period.

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.
