Break-Even Calculator
Find how many units you need to sell to cover costs.
Planning estimate. Real-world break-even depends on taxes, lender fees, and other costs this calculator does not model. Not financial advice.
About Break-Even Calculator
Break-Even Calculator tells you how many units you have to sell to cover your costs, and the revenue level at which the business stops losing money. It is the first number every founder, freelancer, and product manager should know before pricing or scaling: below break-even every additional unit deepens the loss; above it, every unit adds to profit.
Worked example: a business has $5,000 a month in fixed costs (rent, salaries, software). Each unit costs $20 to make and sells for $45. The contribution margin per unit is $45 − $20 = $25. Break-even is 5,000 ÷ 25 = 200 units a month, or $9,000 in revenue. Sell 250 units that month and you are $1,250 in profit; sell 150 and you are $1,250 in the red.
What counts as fixed versus variable matters and is the easiest place to get it wrong. Fixed costs are everything that does not move with sales volume — rent, payroll, subscriptions, equipment leases. Variable costs are per-unit — raw materials, packaging, payment processing fees, fulfillment, shipping. Mixing them up — treating a salary as variable, or shipping as fixed — gives a wrong break-even and a wrong sense of how much you can scale before the next round of fixed costs kicks in. The calculator also assumes a single price and a single variable cost; for a multi-product business use the weighted average across your mix.
