Enter a price, a cost per sale and your fixed costs to see the result.
How it is calculated
- Margin per sale = price − cost per sale.
- Break-even sales = fixed costs ÷ margin per sale, rounded up.
- Monthly profit = expected sales × margin per sale − fixed costs.
- Payback period = start-up money ÷ monthly profit.
A worked example (invented numbers)
A coffee cart sells a cup for 15. The coffee, milk and cup cost 5, so the margin is 10. Rent, wages and its other fixed costs come to 9,000 a month, so it needs 9,000 ÷ 10 = 900 cups a month to break even: about 30 a day. At 1,500 cups a month it makes 1,500 × 10 − 9,000 = 6,000 a month, and 36,000 of start-up money comes back in 36,000 ÷ 6,000 = 6 months. These numbers are made up to show the method. They are not market data.
What this does not tell you
- Whether anyone will buy. The sales figure is your estimate: test it with real customers before you rely on it.
- Slow months. Most businesses take months to reach their usual sales, and some months are seasonal. The payback period assumes every month is like the one you entered.
- Tax, financing and your own salary, unless you have included them in the costs above.
