How break-even is calculated

The break-even point is where total revenue matches total cost. This calculator divides fixed costs by contribution per unit to estimate how many sales you need before profit starts.

Example

Example use case

With £1,000 fixed costs, a £25 sale price and £10 variable cost, the contribution per unit is £15 and break-even is about 67 units.

Frequently asked questions

Why is break-even useful?

It helps you understand minimum sales targets.

What if price equals variable cost?

Then contribution per unit is zero and break-even cannot be reached.

Can I use this for services?

Yes, if you can estimate price and variable delivery cost per sale.
