Answer- Variable Cost per hour = $1.3 per hour.
Total variable cost at 90000 direct labor hours = $117000.
Total fixed costs = $48000.
Explanation:-High-Low Method:-
Variable Cost per Unit
Variable cost per unit (b) is calculated using the following formula:
Variable cost per unit = (Y2-Y1)/(X2-X1) |
|
Where,
y2 is the total cost at highest level of activity;
y1 is the total cost at lowest level of activity;
x2 are the number of units/miles/ labor ,machine hours etc. at
highest level of activity; and
x1 are the number of units/miles/ labor, machine hours etc. at
lowest level of activity
The variable cost per unit is equal to the slope of the cost volume line (i.e. change in total cost ÷ change in number of machine hours).
Total Fixed Cost
Total fixed cost (a) is calculated by subtracting total variable cost from total cost, thus:
Total Fixed Cost = (y2 – b)*x2 = (y1 – b*x1) |
We have,
at highest activity: x2 = 90000 hours;
y2 = $165000
at lowest activity: x1 = 40000 hours;
y1 = $100000
Variable Cost per labor hour = ($165000 - $100000) /(90000 hours − 40000 hours)
= $65000/50000 hours
= $1.3 per hour
Total variable cost on 90000 hours = 90000 hours*$1.3 per hour
= $117000
Total fixed costs= $165000 - $117000
= $48000
