Break-even analyzer

Find how many units you need to sell to cover your costs, and see how a change in price moves the answer.

Your numbers

Fixed costs ($)Costs that do not change with volume (rent, salaries, software) for the period you are analyzing, such as one month.

Price per unit ($)

Variable cost per unit ($)

Variable cost is what each additional unit costs you: materials, fulfillment, payment fees.

Target profit, optional ($)

Expected units, optionalSame period as fixed costs.

What if you change your price?

Price change	Price	Break-even units	Break-even revenue

Break-even units = fixed costs divided by (price minus variable cost per unit), rounded up to whole units. The analysis assumes a single product with a constant price and constant variable cost per unit, and that fixed costs stay fixed across the range shown. Margin of safety is the share of expected units above break-even. This is a planning estimate, not financial advice.
