Multi-product break-even calculator

Enter fixed costs for the period, and for each product its price, variable cost per unit, and share of total sales. The calculator works out the mix's weighted contribution margin and the revenue threshold at which the business breaks even.

How it is calculated

A basic break-even calculation assumes a single product with a single margin. With several products at different margins, you need the mix's weighted contribution margin: each product's margin [(price − variable cost) ÷ price] is multiplied by its share of sales, and the results are summed.

Break-even revenue = fixed costs ÷ weighted mix margin. That's the revenue at which the combined contribution profit from every product together just covers fixed costs.

The result depends heavily on the assumed sales mix — if the actual mix shifts toward lower-margin products, the break-even threshold rises even if prices and costs haven't changed. It's best to use a realistic mix based on past actuals rather than a hoped-for one.
