Divide your total fees by your total volume — the only number that compares cleanly across processors.

Enter your price and your revenue goal. Get the number of customers — and the pace to reach it.

Drag the price and watch the customer count collapse. Same revenue, very different companies.

The MRR you need to cover a real salary and your running costs — not just to break even.

Four numbers in. Revenue, costs, profit, margin and break-even out.

Blended and paid CAC side by side — the gap between them is the number that matters.

A verdict, not just a number — including whether you should be spending more.

Customer churn and revenue churn side by side — because the gap between them tells you who is leaving.

The metric investors ask about first — and what it compounds to over three years.

Itemise your cost of goods sold and see exactly what each line costs you in margin.

An ARR multiple range driven by growth, retention and margin — presented as a range, because that is what it is.

How many months before a customer has paid back what you spent to win them.

Growth plus profit against the 40 line — and what the other half would need to be.
