Fine print worth reading

Rewards only pay out if you pay in full each month. Carrying a balance at 22% APR wipes out 3% cashback on day one. Also: annual fee cards only beat 2% flat if your spend matches the bonus categories โ€” check the math with your real monthly numbers.

How we built this tool

How we rank them

Step 1

Real spending beats marketing copy

A card advertising 6% grocery is only worth it if you actually spend $500+/month on groceries. We multiply your numbers by each card's category rate, not the advertised max.

Step 2

Annual fee is subtracted every year

Welcome bonuses inflate year 1. We show year 1 net AND year 2+ steady state so you can see which card wins long term โ€” often a different answer.

Step 3

The assumption that kills all rewards

You must pay in full monthly. Carrying a balance at 22% APR on $5,000 eats $1,100/yr in interest โ€” which wipes out even the best 5% categories.
