(2) (a) Variable setup-related overhead spending variance = actual variable setup–
related overhead costs − budgeted variable setup-related overhead costs based
on inputs (i.e., based on actual setup hours worked during the year)
= (actual batches × actual setup hours/batch × actual variable setup-related
overhead costs/setup hour) − (actual batches × actual setup hours/batch ×
(b) Variable setup-related overhead efficiency variance = FB for variable setup–
related overhead costs based on Inputs − FB for variable setup-related
overhead costs based on Outputs
= $3,825 − (36 batches × 4 setup-hours/batch × $20.00/setup hour)
variance for variable setup-related overhead costs is due to a combination of the
following two factors: (1) the actual output of the period (9,000 units) took 9 more
batches than standard (actual # of batches = 45; standard allowed batches = 36,
as shown above); and (2) each setup took slightly more time than standard (4.25
hours/setup vs. 4.00 hours/setup). The net unfavorable variable setup-related
overhead variance indicates that the favorable spending variance was not
enough to offset the unfavorable efficiency variance.
(3) Fixed setup-related overhead costs are controlled primarily prior to the point of
operations. That is, they are controlled primarily through the planning process (for
example, the capital budgeting process or the use of zero-based budgeting). These
costs basically relate to the capacity/ability to produce.
On the other hand, variable setup-related costs, by definition, vary in response to
one or more underlying causal factors (cost drivers). Therefore, these costs are
controlled by attempting to identify and eliminate non-value-added activities and to
perform value-added activities more efficiently. ABC systems, because of their
