Rewards credit cards pay you back for spending you would do anyway. Used well, they can return hundreds of dollars a year. Used poorly, they encourage overspending and interest charges that wipe out every reward. This guide explains how rewards work and how to judge whether a card is worth it for you.

Rule number one: pay in full

A card that earns 2% back but charges a 22% APR on a carried balance is a very bad deal if you don’t pay in full. Rewards only make sense when you pay your full statement balance every month. If you carry a balance, focus on a low APR or a balance transfer instead.

The three types of rewards

Cash back

Returned as a statement credit, bank deposit or check.

• Flat-rate: the same percentage on every purchase. Simple and predictable.
• Tiered categories: higher rates in fixed categories like groceries, dining or gas.
• Rotating categories: higher rates in categories that change quarterly, often with activation required and spending caps.

Points

Issuer currencies redeemable for travel, statement credits, gift cards, merchandise or transfers to airline and hotel partners. The value per point varies by redemption method.

Miles

Tied to an airline or hotel loyalty program. Often most valuable for flights or stays with that brand, and may come with perks like free checked bags or priority boarding.

How to value rewards

Convert everything into cents per dollar spent:

• A 1.5% cash back card returns 1.5 cents per dollar.
• A card earning 3 points per dollar on dining, with points worth 1 cent each, returns 3 cents per dollar on dining.

Then estimate your annual rewards based on your actual spending and subtract the annual fee.

Example: $20,000 in annual spending

Spending mix: $6,000 groceries, $3,000 dining, $2,000 gas, $9,000 everything else.

Hypothetical cards for illustration. Actual earning rates, caps and fees vary.

In this example, the simple flat-rate card wins. With heavier grocery and dining spending — or higher-value travel redemptions — the premium card could come out ahead. That is why you should run your own numbers.

Sign-up bonuses

Many cards offer a bonus for spending a set amount within the first few months. Bonuses can be valuable, but:

• Only pursue them with spending you would do anyway.
• Make sure you can pay the full balance.
• Opening several cards in a short time can lower your score and may conflict with issuer application rules.

Annual fees: when are they worth it?

An annual fee makes sense only when the extra rewards and benefits you will actually use exceed the fee compared with a no-fee alternative. Benefits such as travel credits, lounge access or insurance only count if you would otherwise pay for them.

Other features to compare

• Foreign transaction fees — important if you travel abroad.
• Redemption flexibility and minimums.
• Caps on bonus categories.
• Purchase protections such as extended warranties and return protection.
• Intro APR offers on purchases or balance transfers.

Rewards traps to avoid

• Carrying a balance to earn rewards.
• Spending more because you’re “earning points.”
• Letting rewards expire or forfeiting them by closing an account.
• Paying an annual fee for perks you never use.
• Chasing too many cards — more complexity, more fees, more risk of a missed payment.

How issuers pay for rewards

Rewards are funded mainly by the interchange fees merchants pay each time a card is used, and by interest and fees from cardholders who carry balances or pay late. Understanding this makes the core rule obvious: the cardholders who benefit most from rewards are the ones who pay in full and never trigger fees. If you carry a balance, you are helping fund other people’s rewards.

Getting the most from any rewards card

• Automate full payment of the statement balance so you never pay interest.
• Redeem regularly — for many cash back programs, statement credits or deposits are the simplest, full-value option.
• Check your card’s benefits page once a year; programs change their categories, partners and redemption values.

Which rewards card fits you?

• Want simplicity? A no-annual-fee flat-rate cash back card.
• Spend heavily in a few categories? A category card that matches your spending.
• Travel often and like optimizing? A travel points card, if the benefits exceed the fee.
• Building credit? Focus on approval and on-time payments first — see credit cards for beginners and how to build credit.

The bottom line

Credit card rewards are a nice bonus for disciplined cardholders — not a reason to spend. Pay in full every month, choose a card that matches how you actually spend and redeem, and make sure any annual fee pays for itself. Learn more in our credit card rewards section.
