Worked Example
Example: $60,000 Contribution Margin on $100,000 Sales
- Contribution Margin: $60,000.00
- Sales Revenue: $100,000.00
Applying the formula yields:
Contribution Margin Ratio: ($60,000 / $100,000) * 100 = 60.00%
Variable Cost Ratio: 100% - 60% = 40.00%

Frequently Asked Questions (FAQ)
What is the contribution margin ratio?
The contribution margin ratio is the percentage of sales revenue remaining after variable costs, representing the portion of revenue that pays down fixed costs and generates net profit.
How do you calculate contribution margin ratio?
Divide contribution margin by total sales revenue and multiply by 100: CM Ratio % = (Contribution Margin / Revenue) * 100.
What does a 60% contribution margin ratio mean?
A 60% CM ratio means that for every .00 of sales generated, .60 goes toward covering fixed overhead and profit, while .40 pays variable costs.
How is CM ratio used in break-even revenue calculation?
Break-Even Revenue = Total Fixed Costs / CM Ratio. A higher CM ratio lowers the sales volume needed to break even.
What is the relation between CM ratio and variable cost ratio?
CM Ratio + Variable Cost Ratio = 100%. If variable costs are 40% of revenue, the CM ratio is 60%.
Why do SaaS businesses have high CM ratios?
Software businesses deliver products digitally, resulting in minimal hosting and variable delivery costs per user.
Can CM ratio change with scale?
Yes, volume discounts on raw materials reduce variable costs, expanding the contribution margin ratio.
How does price discounting impact CM ratio?
Discounting selling prices lowers sales revenue without reducing variable unit costs, shrinking the contribution margin ratio.
