Most credit cards offer rewards programs. Usually, these take the form of points that you can accumulate by using the card (which are almost always tied to the dollar amount you charge) and are redeemable for gifts, discounts from various merchants, or services.

Some rewards cards offer cash back or rebates. However, make sure you understand the fine print on these programs. In many cases, you can benefit from them only if you pay off your full balance every month.

If you carry a balance on your credit card, the high interest rate you pay will dilute the value of your rewards almost immediately. If you ordinarily carry a balance, you should consider a credit card with a low annual percentage rate (APR), rather than one that offers a rewards program.

You can benefit the most from a rewards program that gives you discounts or rebates from a retailer or supplier you frequent a lot. For example, if you travel on a particular airline and your credit card offers you frequent flier miles on that airline, it might be a good deal.

Some credit cards offer rewards specific to a certain category, such as travel, automotive, or home improvement, among others. If you spend a lot of money working on your house and garden, it might make sense to find a credit card that offers rewards for products or services you would be able to use.
