About this tool

The break-even point is the sales volume at which total revenue equals total costs: you make neither a profit nor a loss. Every unit sold above it adds its contribution margin to your profit.

Frequently asked questions

What is a break-even point?

It is the number of units (or the amount of revenue) at which your sales exactly cover your fixed and variable costs, so profit is zero.

What is the difference between fixed and variable costs?

Fixed costs stay the same whatever you sell (rent, salaries, subscriptions). Variable costs grow with each unit sold (materials, packaging, shipping, payment fees).

What if my price is lower than my variable cost?

Then each sale loses money and you can never break even: raise the price or lower the variable cost.

Are my numbers saved or sent anywhere?
