The number of sales and the average ticket. Everything else follows from them. The calculator below shows your revenue and profit today — and what happens when you nudge each of the two levers.
We talk to business owners every week. Ask how their revenue is built, and many say: “My accountant knows that.” The accountant knows what happened last month. Running a business means deciding what happens next.
And that comes down to two numbers:
That’s it. Ads, the website, staff, discounts, photos, reviews — they all affect your business through these two levers only: how many times people buy and how much they pay each time. You can cut costs, but costs have a floor. Sales and ticket don’t.
Costs stay put. Only the number of sales and the average ticket move.
A simplified model: fixed costs stay flat, variable costs stay the same % of the ticket. In real life more sales may need more staff or ads — factor that in yourself.
Move both levers by 10%. Revenue grows 21%: 1.1 × 1.1 = 1.21. Profit grows much more. The reason is simple: rent and payroll don’t go up because you sold more. Once fixed costs are covered, almost every extra sale drops to profit.
That’s why two small wins — a few more customers and a slightly higher ticket — usually beat one big painful move, like slashing costs.

Revenue = number of sales in a period × average ticket. Profit = revenue − costs: variable costs (which grow with each sale) and fixed costs (the same every month).
An accountant reports what already happened. How to get more sales and raise the ticket is the owner’s call — and it starts with knowing the two numbers.
Sometimes it’s worth it. But costs have a floor — rent never goes to zero. Growth in sales and ticket has no such ceiling, and profit grows faster because fixed costs stay the same.
The number of sales a month at which revenue covers all costs. Everything above it is profit. The calculator works it out for you.
For a business with a ticket in the thousands, one customer from search is enough for a website to pay off. A calculator on your own numbers.
