Setting Standard Costs
Accountants, engineers, personnel
administrators, and production managers
combine efforts to set standards based on
experience and expectations.

Setting Standard Costs
Engineer&Managerial
Accountant: “Should we
use practical standards
or ideal standards?”
Production Manager: “Practical standards
should be set at levels that are currently
attainable with reasonable and efficient
effort.”
HRD: ”I agree. Ideal
standards, based on
perfection, are unattainable
and discourage most
employees.”

Standards vs. Budgets
Are standards the
same as budgets?
A budget is set for
total costs.

A standard is a per
unit cost.
Standards are often
used when
preparing budgets.

Standard Cost Variances
A standard cost variance is the amount by which
an actual cost differs from the standard cost.
Cost
Standard
McGraw-Hill/Irwin
This variance is unfavorable
because the actual cost
exceeds the standard cost.

Standard Cost Variances
I see that there
is an unfavorable
variance.
But why are
variances
important to me?
McGraw-Hill/Irwin
First, they point to causes of
problems and directions
for improvement.
Second, they trigger
investigations in departments
having responsibility
for incurring the costs.

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.

Note: Using the formulas
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

Quick Check 
Suppose only 190 kgs of fiberfill were used to
make 2,000 parkas. What is the materials

cost of $5 per kg of fiberfill.
a. $50 F
