Good to know
Good to know
The break-even calculator calculates directly in your browser either the break-even quantity and corresponding revenue, the required selling price, or the required revenue from a contribution margin ratio. Units can be treated as whole-only or fractional, and an optional revenue-based cost is additionally factored in.
Typical searches include calculate break-even, break-even point, and contribution margin calculator. Calculation runs locally in the browser. An optional target profit and a comparison with expected sales additionally show a safety margin or revenue gap; the model assumes constant prices and variable costs.
Typical use cases
Determine minimum sales volume for a new product
Enter fixed costs, selling price, and variable cost per unit to calculate the minimum sales volume to reach break-even.
Calculate the required selling price for a cost target
Use the “required selling price” direction to find, at a fixed sales volume, the price that reaches break-even.
Tips for better results
Deliberately choose whole or fractional units
For physical products, only whole units usually make sense; for services or bulk goods, fractional units can be more realistic.
Don't forget revenue-based costs
Commissions, payment fees, or marketplace costs that scale with revenue should be enabled separately as revenue-based costs.

Frequently asked questions
Frequently asked questions
Does the calculator account for discounts or volume pricing?
No. The model assumes constant prices and variable costs; discounts, capacity limits, and demand effects change the model and would need to be factored in separately.
