Exercise 216A Estimating fixed and variable costs using the
Solution
1.
First let’s calculate variable cost per unit using the identified high and low activity levels:
Variable cost =
(Total cost of high activity – Total cost of low activity)/(Highest activity unit- Lowest activity unit)
= ($ 158,880 - $ 52,000)/(200 – 33)
= $ 106,880/ 167 = $ 640 per unit
We can input the value of variable cost in high or low cost to find out total fixed cost as:
Total cost = (Variable cost per unit x Units produced) + Total fixed cost
$ 158,880 = ($ 640 x 200) + Total fixed cost
Total fixed cost = $ 158,880 - ($ 640 x 200)
Total fixed cost = $ 158,880 - $ 128,000 = $ 30,880
2.
Total cost = Fixed cost + (Variable cost per unit x Units produced)
= $ 30,880 + ($ 640 x 120)
= $ 30,880 + $ 76,800 = $ 107,680
