How to use the marketing roi calculator
What it does: Enter what a campaign cost and how people responded to see revenue, profit, return on spend, and cost per new customer.
When to use it: Use it before you spend on marketing or sales, and after a campaign to see what worked.
- Start with the example numbers to see how it works.
- Replace them with your own figures from your bank statements, invoices, or bookkeeping. Estimates are fine.
- Read the plain-language result at the top, then change one number at a time to see what moves it most.
The calculator is free, needs no account, and doesn't store what you type.
