Break-even calculator
The rent, the wages and the power bill are owed before you’ve sold a thing. Put in your own numbers to see how many sales it takes to cover them, then try a change beside it.
How to use it: pick your main product or service. Enter what a customer pays, what one costs you to make or buy, and the bills you pay each month whatever you sell (rent, wages, power, insurance, subscriptions). Round figures are fine. Leave GST out.
Option B is there to compare: a rent rise, a new hire, a dearer supplier or a price rise.
This treats your running costs as fixed and your cost per item as the same for every sale. Real businesses are lumpier than that, and most sell more than one thing, so use an average or your main seller. The day of the month assumes sales come in evenly. Nothing you type is saved or sent anywhere.
