The break-even calculator tells you the daily sales your shop needs to pay for its goods and its monthly costs, with nothing left over. Sales above that line are profit; below it, you are losing money that day. It is free, needs no account, and runs in your browser.
Use it
- Pick your currency. It starts on US dollars.
- Enter your monthly costs: rent, wages, electricity, water and internet, and anything else that is due whether or not you sell anything. Include your own pay if you draw one, or the answer will look better than it is.
- Enter your cost of goods as a percentage: out of every 100 you sell, how much went on buying or making it?
- Enter the days you are open each month.
- Optionally, enter your average sale per customer to see how many customers a day that takes.
Why the answer is bigger than your bills
The goods you sell cost money too, so only part of each sale is left to pay the fixed costs. If the goods are 70% of the price, each 100 sold leaves 30. To cover 15,000 of monthly costs you need 50,000 in sales, not 15,000.
Finding your cost of goods
Divide what you spent on stock in a month by what you sold. Kasenso's reports show your sales and cost side by side, which replaces the guess.
When the number looks out of reach
You can cut a fixed cost, lower what the goods cost you, or raise prices. A few points off the cost of goods moves the target a lot. Use the pricing calculator to see what a price change does for each item.
Frequently asked questions
Why does it say break-even is impossible?
If the goods cost 100% or more of what they sell for, each sale loses money and more sales make it worse. Fix your prices or your supplier cost first.
Should I include my own salary?
Yes, if you take one. Otherwise you can break even on paper while working for nothing.
Is this a forecast?
No. It is the arithmetic of your own numbers. It does not know about slow seasons, so use a typical month.
Is my data saved or sent anywhere?
No. It is calculated in your browser and gone when you close the page.
