What Is Break-Even Point?

Break-even is calculated by dividing total fixed costs by the contribution margin (price per unit minus variable cost per unit): Fixed Costs ÷ (Price − Variable Cost per Unit) = Break-Even Units. A business selling a product for $50 with $30 in variable costs per unit and $40,000 in monthly fixed costs needs to sell 2,000 units a month ($40,000 ÷ $20) just to cover its costs — the 2,001st unit is the first one that generates actual profit.

Break-even analysis is one of the most practical tools for pricing and cost decisions: it shows exactly how a price change, a new fixed cost (like a new hire), or a shift in variable costs (like a supplier price increase) moves the sales volume needed just to stay afloat. It's also a standard requirement in lender and investor financial models, since it demonstrates the founder understands their own unit economics.

Many small businesses set prices based on competitor benchmarks or gut feel without ever calculating their actual break-even point, and end up unknowingly selling at a loss once all costs are accounted for. An accountant or fractional CFO can build a break-even model tied to your real cost structure, so pricing, hiring, and expansion decisions are grounded in the number of sales actually required to support them.
