Answer:
Contribution margin = Revenue − Variable costs
Step-by-Step Explanation
For example, if the price of your product is $20 and the unit variable cost is $4, then the unit contribution margin is $16.
The first step in doing the calculation is to take a traditional income statement and recategorize all costs as fixed or variable. This is not as straightforward as it sounds, because it’s not always clear which costs fall into each category.
Hope this helps and if it does, don't be afraid to rate my answer as well as maybe give it a "Thanks"? (Or even better a "Brainliest"). And if it’s not correct, I am sorry for wasting your time, and good luck finding the correct answer :)
