Break-Even Calculator
Find the break-even point for a product or service: the number of units you must sell to cover your costs. Enter fixed costs, the price per unit, and the variable cost per unit; the calculator returns the contribution margin per unit and as a ratio, the break-even unit count and revenue, and — if you enter an actual sales level — the profit at that volume and the margin of safety. All arithmetic runs locally in your browser.
Contribution margin per unit = price − variable cost. Break-even units = fixed costs ÷ contribution margin per unit (rounded up to a whole unit). Break-even revenue = break-even units × price. Contribution margin ratio = contribution margin ÷ price. Margin of safety = (actual units − break-even units) ÷ actual units. Profit at actual volume = (price − variable cost) × actual units − fixed costs. All values must be non-negative and price must exceed variable cost to break even. Runs locally.
