Quick answer

Spending $2,000 a month on a 2% card with no fee earns $480 a year — about $40 a month.

How it works

Cash back is a percentage of what you spend returned to you. If your card has an annual fee, subtract it — a fee card only wins if the extra rewards beat the fee.

Formula

Net cash back = (Monthly spending × 12 × Rate) − Annual fee

Assumptions & limitations

All spending earns the same rate
No spending caps or rotating categories
Balance paid in full — interest would erase rewards

Frequently asked questions

Is a card with an annual fee worth it?

Only if the extra rewards exceed the fee. Compare the net cash back here against a no-fee card.

Does cash back expire?

Usually not while the account stays open, but check your card's terms.
