Cash Back Calculator
Work out whether a rewards card actually pays: cash back earned, the annual fee subtracted, and the spending level where the fee breaks even.
Every figure below is labelled in the currency you pick. Amounts are not converted — enter values in the same currency.
How to use the Cash Back Calculator
- Fill in each field with your own figures — the defaults are only there as an example.
- The result updates as you type, so there is no button to press.
- Check the breakdown under the main result for the supporting numbers.
- Use the copy button to take the result with you, or share the link to reload the same inputs.
Cash Back Calculator — frequently asked questions
Do rewards matter if I carry a balance?
No. At a typical 22% APR, interest on a carried balance costs roughly ten times what 2% cash back returns. Rewards cards only make sense when the statement is paid in full every month.
Is this cash back calculator free to use?
Yes. Every calculator on the site is free, needs no sign-up, and runs entirely in your browser, so your figures never leave your device.
How accurate is the result?
The maths is exact for the formula shown on the page. Accuracy in the real world depends on your inputs and on assumptions the formula cannot see, so treat the output as a well-grounded estimate rather than a quote.
Can I use it on my phone?
Yes. The page is responsive, weighs a few kilobytes and works offline once loaded, so it behaves the same on a phone as on a desktop.
