Break-even calculator for small business.
Enter your monthly fixed costs, what you sell things for on average, and what each sale costs you. See how much you need to sell — per month and per day — to break even.

Defaults work for most small shops in the EU.
Units per day to break even
Why contribution margin is the only break-even input that matters.
Break-even is simple: how many sales does it take to cover all your fixed costs? The answer is monthly fixed costs divided by what each sale "contributes" toward covering them.
The formula
Sales per month = monthly fixed costs ÷ (price − variable cost)Sales per day = monthly ÷ days open
What contribution margin tells you
A €25 sale that costs you €9 contributes €16 to the fixed costs. If your rent and salaries add up to €4.500/month, you need 282 sales to break even — about 11 per day if you're open 26 days. Below that you're losing money; above it, every additional sale is profit.
Three levers that move break-even
Lower your fixed costs, raise your price, or lower your variable cost per sale. Most owners obsess over the third and ignore the second. Pricing is usually the biggest unused lever.
