Contribution Margin Calculator

Contribution margin is the revenue remaining after subtracting variable costs. It shows how much each sale contributes to covering fixed costs. For example, if you sell a product for $100 with $60 in variable costs, your contribution margin is $40 per unit.

A contribution margin ratio of 40-60% is considered healthy for most businesses. High-margin businesses (software, consulting) often achieve 70%+. Retail and manufacturing typically operate at 20-40%. Higher ratios mean more flexibility in pricing and marketing spend.

Use contribution margin to determine minimum viable pricing. Your price must cover variable costs and contribute to fixed costs. If your CM per unit is $40 and monthly fixed costs are $10,000, you need to sell 250 units to break even. This helps set sales targets and pricing floors.

Contribution margin considers only variable costs (materials, direct labor). Gross margin includes both variable and some fixed manufacturing costs (like factory overhead). Contribution margin is more useful for decision-making because it shows the true incremental profit from each sale.

Improve contribution margin by: 1) Raising prices strategically, 2) Reducing variable costs through better supplier terms, 3) Improving operational efficiency, 4) Eliminating low-margin products, 5) Increasing sales of high-margin items through bundling or promotions.
