What is contribution margin?

Contribution margin is the amount each unit sale contributes toward covering fixed costs and generating profit. It is calculated as: Selling Price − Variable Cost per Unit. For example, if you sell a product for $50 and it costs $30 to produce, your contribution margin is $20 per unit. The contribution margin ratio expresses this as a percentage of the selling price: $20 / $50 = 40%.

What are fixed costs vs. variable costs?

Fixed costs stay the same regardless of how many units you produce or sell — examples include rent, salaries, insurance, and loan repayments. Variable costs change directly with production volume — examples include raw materials, packaging, direct labor per unit, and shipping. Understanding the distinction is critical for accurate break-even analysis and pricing decisions.

How can I lower my break-even point?

There are three main levers: (1) Reduce fixed costs — negotiate lower rent, streamline operations, or cut overhead. (2) Reduce variable costs — find cheaper suppliers, improve production efficiency, or reduce waste. (3) Increase selling price — if the market allows, a higher price means each sale contributes more margin, so fewer units are needed to break even. Use this calculator to test each scenario.

What is the margin of safety?

The margin of safety is the difference between your actual (or projected) sales and the break-even point. It tells you how much sales can drop before you start losing money. For example, if your break-even is 500 units and you sell 800, your margin of safety is 300 units (37.5%). A higher margin of safety means your business is more resilient to downturns in demand.

Frequently Asked Questions

The break-even point is the sales volume at which total revenue equals total costs — meaning you make neither a profit nor a loss. Any sales below this point result in a loss; any sales above it generate a profit. Knowing your break-even point is essential for pricing, budgeting, and evaluating the viability of a business or product.
