Exercise 3-13 (30 minutes)
High activity level (First quarter) …
Low activity level (Third quarter) …
Variable cost = Change in cost ÷ Change in activity
= $120,000 ÷ 60,000 units
= $2.00 per unit produced
Total overhead cost (First quarter) ………………………..
Variable cost element ($2.00 per unit × 80,000 units) .
Fixed cost element …………………………………………….
These fixed and variable cost estimates can be used to estimate the to-
tal manufacturing overhead cost for the fourth quarter as follows:
Y = $140,000 + ($2.00 per unit)(60,000 units)
Estimated fixed manufacturing overhead ………………
Estimated variable manufacturing overhead
$2.00 per unit × 60,000 units …………………………..
Estimated total manufacturing overhead cost …………
Total manufacturing cost and unit product cost:
Direct materials ……………………………………………..
Direct labor ………………………………………………….
Manufacturing overhead ………………………………….
Total manufacturing costs ………………………………..
÷ Number of units to be produced …………………….
= Unit product cost (rounded) ………………………….
