Formula and methodology
Formula: CM = sales - variable; ratio = CM / sales x 100.
Contribution margin is what remains from sales after variable costs to cover fixed costs and profit. The ratio expresses that remainder per 100 of sales.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Sales — Total sales for the period; must be greater than zero.; minimum 0; maximum 1000000000000
- Variable costs — Costs that scale with volume; zero or more.; minimum 0; maximum 1000000000000
Worked example
| Input | Value |
|---|---|
| Sales | 100000 |
| Variable costs | 60000 |
CM 40000.00; ratio 40.00%.
Assumptions and limits
- Sales and variable costs cover the same period in one currency.
- Costs split cleanly into variable and fixed; fixed costs are out of scope.
