Contribution Margin Calculator — Calculate contribution margin and ratio from revenue and variable costs. Enter Revenue, Variable costs, Price per unit (optional), Variable cost per unit (optional) to get an instant, accurate result.

計算式

Contribution margin = revenue − variable costs. Contribution margin ratio (%) = (contribution margin / revenue) × 100. Per-unit contribution margin = price per unit − variable cost per unit.

ステップごとの説明

  1. Enter the Revenue.
  2. Enter the Variable costs.
  3. Enter the Price per unit (optional).
  4. Enter the Variable cost per unit (optional).
  5. Click Calculate to see your result instantly.

実例

Example: With Revenue = 100000, Variable costs = 60000, Price per unit (optional) = 0, Variable cost per unit (optional) = 0, the Contribution Margin Calculator gives Contribution Margin: 40000, Contribution Margin Ratio Pct: 40, Contribution Margin Per Unit: 0.

よくある質問

How is contribution margin different from gross profit?
Gross profit subtracts all cost of goods sold (which can include some fixed manufacturing costs); contribution margin subtracts only variable costs, isolating how much each sale contributes to covering fixed costs.
Why does the contribution margin ratio matter?
It shows what share of every revenue dollar remains after variable costs to pay down fixed costs and generate profit — a higher ratio means each sale is more profitable before fixed costs.
What inputs does the Contribution Margin Calculator need?
You'll need to provide: Revenue, Variable costs, Price per unit (optional), Variable cost per unit (optional). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Contribution Margin Calculator?
The Contribution Margin Calculator applies the formula exactly as calculated — Contribution margin = revenue − variable costs. Contribution margin ratio (%) = (contribution margin / revenue) × 100. Per-unit contribution margin = price per unit − variable cost per unit. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Contribution Margin Calculator free to use?
Yes, the Contribution Margin Calculator is completely free, requires no signup, and runs instantly in your browser.
