Break-even is the revenue level where contribution margin covers all fixed costs. Beyond break-even, each contribution unit becomes profit. Before break-even, each unit reduces losses.
Many operators use 'break-even' casually to mean 'sustainable.' In practice, break-even is a specific calculation: the revenue point where contribution margin covers fixed cost.
This guide explains break-even analysis in the context of the decisions that actually matter: pricing, volume, and cost structure choices that move the break-even point.
The result is the revenue level at which the business stops losing money and begins creating profit.
A business with no fixed costs never has a break-even point. Every unit contributes immediately to profit. The larger the fixed cost base (payroll, rent, overhead), the higher the break-even revenue needs to be.
If break-even requires 200 units per month and the market will not support that volume, the business model is broken regardless of how good the unit margin looks. Break-even forces that reality check early.
Worked example
A SaaS business has $200,000 in monthly fixed costs and a $99-per-month subscription with 60% contribution margin.
Break-even shows when the business reaches profitability, not just when it achieves growth.
