Know the sales you need each month to cover your costs.

Every business has a number: the sales needed each month to cover the bills. Enter your monthly overhead, your average sale, and what each sale costs you to deliver. The calculator shows the sales you need per month and per week, and the revenue that represents.

Once you pass that number each month, you're working for profit. And if each sale costs as much as it brings in, the calculator warns you, because more sales alone won't fix it.

You enter: monthly overhead, average sale, and the cost of each sale.

You get: sales needed per month and per week, and your monthly break-even revenue.

Best for: every owner who wants to know their monthly target, and anyone planning a price change or a new hire.
