Small Business Break-Even Calculator

Find how many units you need to sell to cover costs for one period. Use the same currency for every amount.

Fixed costs must cover this entire period.
Examples: rent, subscriptions, and equipment leases.
Amount received for each unit sold.
Costs that arise with each unit, such as materials.

Amounts accept up to two decimal places and a maximum of 1,000,000,000. Revenue equals rounded-up units × selling price, so it may slightly exceed the exact cost-covering threshold. Assumes every unit is sold and prices and unit costs stay constant.

How to use the break-even calculator

Choose a period, then enter the fixed costs that apply to that entire period. For example, use monthly rent and monthly subscriptions when you select Month. Next, enter your selling price per unit and the variable cost of producing or delivering one unit. Use the same currency throughout. A unit can be a physical item or a consistently defined service package.

Select Calculate break-even to see your contribution per unit: selling price minus variable cost. The calculator divides fixed costs by this contribution and rounds the result up to a whole unit. It then multiplies that rounded unit count by the selling price to show the corresponding sales revenue. For example, fixed costs of 3,000, a price of 50, and a variable cost of 20 produce a contribution of 30, a threshold of 100 units, and sales revenue of 5,000.

Why it helps

This calculation makes the relationship between costs, prices, and sales volume easier to understand. Change one input at a time to compare scenarios. If price is no greater than variable cost, the tool explains why there is no break-even point with those inputs. Results assume constant prices and costs, with every unit sold; they are not a forecast of demand or a guarantee of profitability. All calculations happen locally in your browser.
