Result
Enter your monthly fixed costs, your average sale and the cost of each sale.
How to use it
- Add up your fixed costs for one month: rent, salaries, bills, loan payments.
- Enter your average sale (or the price of one item) and what that sale costs you — stock, packaging, card fees.
- Optionally enter the days you open each month to see sales needed per day.
The formula
- Contribution per sale = average sale − cost per sale
- Break-even sales = fixed costs ÷ contribution per sale (rounded up)
- Break-even revenue = break-even sales × average sale
Questions
What counts as a fixed cost?
Costs you pay whether you sell or not: rent, salaries, electricity standing charges, internet, software, loan payments. Costs that grow with each sale — stock, packaging, delivery, card fees — go in “cost per sale”.
Why does it say break-even is not possible?
If each sale costs you as much as you charge (or more), every extra sale adds to the loss. Raise the price or lower the cost per sale first.
Should I use prices with or without tax?
Without tax. The tax you collect is passed on to the government.
Is my data saved?
No. The calculator runs in your browser and nothing you type is sent or stored.
