In-depth explanation
Find how many units you must sell to cover fixed costs, given price and variable cost per unit. Also shows contribution margin and revenue at break-even. Everything runs locally in your browser — your inputs are not uploaded to produce the result.
Fixed costs stay roughly the same regardless of sales (rent, salaried staff). Variable costs rise with each unit (materials, shipping). Price minus variable cost — the amount each sale contributes toward covering fixed costs and profit.
Otherwise every sale loses money on a unit basis and you can never break even by selling more. Use Break Even Calculator for quick planning; confirm important money, tax, or health decisions with an official source or professional when needed.
Break-even units = fixed costs ÷ (price − variable cost). If variable cost is above price, more sales make the hole deeper. Contribution margin is that gap per unit.
Fixed vs variable is a judgement: a warehouse might be fixed this year and variable if you scale. This model is one product, one price. Real businesses have mix, discounts, and tax. Use it for a first sketch.
