Answer:
First question:
What is the cost effect of the growth component for conversion costs?
Conversion Cost growth component: 0
Second: Throughput contribution
Revenues minus all direct material costs of goods sold
Explanation:
1st: Q: What is the cost effect of the growth component for conversion costs?
Givens: 2017 2018
Manufacturing capacity: 50,000 48,400
Conversion Cost
per unit of capacity: 25 25
As there is capacity for 50,000 units on 2017 there is no additional cost incurred for a capacity of 48,400
Thus, this makes the grow component effect for conversion cost equal to zero.
2nd Q: Throughput contribution is the difference between the sales revenue generated and the cost of the materials. It indicates the value added to the raw materials through the manufacturing process That's why his named "throughput contribution"
There is a difference with the common term "contribution margin" as this takes all variable cost into consideration.
