Cost
a. Bike frames
Variable
b. Screws for assembly
Variable
c. Repair expense for tools (If these costs are only remotely related
to volume, they may be better classified as fixed)
Variable
d. Direct labor (If employees receive monthly salaries, this cost would
be fixed)
Variable
e. Bike tires
Variable
f. Gas used for heating**
Variable
g. Incoming shipping expenses*
Variable
h. Taxes on property
Fixed
i. Office supplies (This item can be a variable cost, but it usually is
not because it doesn’t often change in direct proportion to changes in
the volume level)
Fixed
j. Depreciation on tools (If the company uses the units-of-
production method, the depreciation would be variable)
Fixed
k. Management salaries
Fixed
* Incoming shipping expenses are variable with respect to the number (volume) of
incoming shipments, not production.
** Gas used for heating is often a mixed cost rather than strictly variable.

1. Preliminary computations
Actual quantity: 22,000 bd. ft. (given)
Standard quantity: 3,000 units x 8 bd. ft./unit = 24,000 bd. ft.
Actual price: $266,200/22,000 bd. ft. = $12.10/bd. ft.
Standard price: $12.00/bd. ft. (given)
$2,200 U
(Price variance)
$24,000 F
(Quantity variance)
$21,800 F
(Total materials variance)
Alternate solution format
Price variance
= AQ x (AP – SP)
= 22,000 board feet x ($12.10 - $12.00)
= $2,200 U
Quantity variance
= (AQ – SQ) x SP
= (22,000 - 24,000) board feet x $12.00/board foot
= $24,000 F
