How to use Break-Even Calculator
- 1Enter your fixed costs (rent, salaries, subscriptions — costs that don't change with sales volume).
- 2Enter your price per unit and variable cost per unit (materials, per-unit fees).
- 3See your break-even point in units and revenue instantly.
- 4Optionally add expected monthly sales to see time-to-break-even.
The formula
contributionMargin = pricePerUnit − variableCostPerUnit (how much each sale contributes toward fixed costs). breakEvenUnits = fixedCosts ÷ contributionMargin. Below this many units sold, you're operating at a loss; above it, each additional unit is pure profit.
Fixed vs variable costs
Fixed costs stay the same regardless of sales volume (rent, salaries, software subscriptions). Variable costs scale with each unit sold (materials, packaging, payment processing fees). Getting this split right is essential for an accurate break-even point.
Frequently Asked Questions
What if my variable cost is higher than my price?
Then you lose money on every unit sold and can never break even, no matter the volume — the calculator will flag this. You need to raise price or cut variable cost first.
Does this account for seasonal or one-time costs?
Fixed costs should be your typical recurring monthly costs. For one-time costs like equipment, consider adding them to your break-even target directly or spreading them across a set period.
