A high rewards rate only helps when it applies to purchases you actually make and the value you receive exceeds the costs.
Use your own spending
Break down a typical month by category. A dining bonus is less useful if most of your spending is groceries. Check whether the advertised rate has a quarterly or annual cap, requires activation or applies only to purchases through a particular portal.
Count the redemption value
Points, miles and cash back can have different redemption rules. Look for minimum redemption thresholds, expiration rules and limits on the advertised value. Treat a welcome bonus separately from ongoing earnings because it may require spending within a deadline.
Subtract costs
Use our rewards calculator for a simple flat-rate illustration. Subtract the annual fee and consider whether interest or other fees would erase the benefit. If you expect to carry a balance, compare the APR before focusing on rewards.
A modest reward you can use may be more valuable than a larger advertised reward with rules that do not match your habits.
