Break-Even Analysis Calculator

About Break-Even Analysis Calculator

The break-even point is the exact number of units a business needs to sell before it starts making a profit — below that number, total costs still exceed total revenue, and above it, every additional unit sold contributes pure profit. Knowing this number precisely, rather than a rough guess, is foundational to pricing decisions, budgeting, and evaluating whether a new product or business idea is financially viable at all.

This tool uses the standard break-even formula: fixed costs divided by the contribution margin per unit, where contribution margin is the selling price per unit minus the variable cost per unit. Fixed costs are expenses that don't change with production volume (rent, salaries, insurance), while variable costs scale directly with each unit produced (materials, per-unit labor, packaging).

The contribution margin is the real engine of this calculation — it represents how much of each unit's sale price is left over after covering that unit's own variable cost, available to go toward paying off the fixed costs first, then toward profit once fixed costs are fully covered. A thin contribution margin means needing to sell a lot of units just to break even; a healthy margin means reaching profitability with far fewer sales.

Beyond the break-even unit count, the tool shows the break-even revenue (units × price) — useful for comparing against a sales target or forecast — and the contribution margin per unit itself, which is worth watching independently since even small changes in price or variable cost can shift the break-even point substantially.

How it works

1. Enter your fixed costs. Total costs that don't change with how many units you sell.
2. Enter variable cost and price per unit. The cost to produce each unit, and what you sell it for.
3. View your break-even point. The exact number of units, and the revenue that represents.
