Free Break-Even Calculator

Find how many units you must sell — and at what revenue — to cover your fixed costs, from price and variable cost.

The break-even calculator computes the point where your revenue exactly covers your costs: enter the selling price, the variable cost per unit, and your total fixed costs, and it returns the contribution margin per unit, the break-even quantity in units, and the break-even revenue. The method is standard: every unit sold contributes price minus variable cost toward fixed costs, so the break-even quantity is fixed costs divided by that contribution. If the price is at or below the variable cost, the calculator refuses to compute — every sale then adds a loss and no break-even point exists. The calculator assumes the business is break-even in the accounting sense (operating profit of zero) and does not include taxes, interest, or one-off items unless you fold them into fixed costs. Full decimal precision is kept internally; rounding applies only to displayed units and money. Everything runs locally in your browser — your numbers never leave your device and are never logged.
