Chapter Outline
V. Overhead Standards and Variances⎯A predetermined overhead rate is used
to assign standard overhead costs to products or services produced;
predetermined rate often based on relation between standard overhead and
standard labor cost, standard labor hours, standard machine hours, or another
measure of production.
A. Setting Overhead Standards
1. Standard overhead costs are amounts expected to occur at a certain
level of activity.
B. Predicting Activity Levels – to establish standard overhead cost rate, use
same cost structure as that used to construct flexible budget at end of a
period.
1. Management selects a level of activity (volume) and predicts total
overhead costs. It then divides this total by the allocation base to get
the standard rate.
2. Many factors affect predicted activity level.
difficulties in scheduling work, equipment under repair or
maintenance, and insufficient product demand.
standard rate.
C. Computing Overhead Cost Variances
1. Cost accounting system applies overhead using predetermined
variable and fixed overhead.
D. Controllable and Volume Variances
1. Controllable variance is the difference between actual overhead costs
incurred and budgeted overhead costs based on a flexible budget.
volume of production and standard volume of production based solely
on fixed overhead.
expected volume, and is computed based on standard direct labor
hours allowed for the expected production volume.
b. Applied fixed overhead is based on standard direct labor hours
