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

Often a single

each labor operation.

The rate is the
variable portion of the
predetermined overhead
rate.
The quantity is
the activity in the
allocation base for
predetermined overhead.
11-8
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.

Responsibility for Material Variances
Materials Quantity Variance
Production Manager
Materials Price Variance
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.
11-18
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.
Production Manager
Quality of training
provided to employees.

Potential Problems with Standard Costs
Emphasizing standards
may exclude other
important objectives.
Standard cost
reports may
not be timely.
Invalid assumptions
about the relationship
between labor
cost and output.
Potential
Problems
Favorable
variances may
be misinterpreted.
Emphasis on
negative may
impact morale.
Continuous
improvement may
be more important
than meeting standards.
