Evanson Company
Flexible Monthly Budget
Activity Level:
Finished goods (Units)          40,000         60,000          80,000
Variable costs:
Direct materials                $560,000     $840,000    $1,120,000
Direct labor                         600,000       900,000     1,200,000
Manufacturing overhead   640,000       960,000     1,280,000
Total variable costs       $1,800,000  $2,700,000  $3,600,000
Fixed manufacturing
  overhead                          135,000         135,000        135,000
Total production costs $1,935,000  $2,835,000  $3,735,000
Explanation:
a) Data and Calculations:
Expected production units per year = 540,000
Average monthly production units = 45,000 (540,000/12)
Manufacturing costs per unit:
Direct materials                            $ 14 
Direct labor                                      15 
Variable manufacturing overhead 16 
Fixed manufacturing overhead       3
Total yearly fixed overhead = $1,620,000 (540,000 * $3)
Monthly fixed overhead = $135,000 ($1,620,000/12)
b) A flexible budget has varying activity levels from one period to the next.  One interesting feature of the flexible budget is that the variable costs are fixed per unit, but their totals vary with the volume levels.  On the other hand, the fixed costs remain static in totals but vary per unit.
