Break-Even Calculator

A free break-even calculator built on contribution margin — what each sale leaves behind after its own variable cost to chip away at fixed costs. The default view solves break-even in whole units from fixed costs, price, and variable cost per unit; a sales-dollars view solves break-even revenue from a blended contribution margin ratio when there is no single "unit"; and a target-profit view extends the formula to the volume that clears a profit goal on top of the bills. Everything is computed in your browser on the numbers you enter, and nothing is uploaded or stored. Treat the result as a planning estimate for sizing a price, a budget, or a sales target — not business, tax, or accounting advice.
