Do credit card rewards actually pay? Run the numbers
What 1%, 2%, and 5% are worth on real spending, and the one thing that erases all of it.
On this page
Rewards are real money, and they are also much smaller than the marketing implies. On typical spending the difference between a good card and a mediocre one is a few hundred dollars a year, and a single month of carried balance can erase it.
What each rate is worth
Take $2,000 a month of card spending, which is a realistic figure for someone putting groceries, fuel, and bills on a card.
Two things stand out. A flat 2% card earns $480 a year, double the 1% card. And the headline 5% rotating card earns only $300, because the 5% applies to a capped slice of spending in changing categories, not to everything.
For most people a single flat-rate card beats a wallet of category cards, because it earns the full rate on everything with no tracking, no activation, and no caps.

The number that erases it all
Here is the comparison that settles the question. Carrying a $2,000 balance at a 24% APR costs about $40 in interest for one month. A 2% card on $2,000 of spending earns $40 in rewards for that month.
They cancel exactly. Carry a balance for a single month and the year of rewards is a month behind. Carry one all year and rewards are irrelevant, because you are paying roughly ten times what you earn. See how card interest compounds.
Rewards are only real for people who pay in full every month. For anyone carrying a balance, the only number that matters is the APR.
What else quietly reduces the return
- Annual fees. A $95 fee on $480 of rewards leaves $385, which can put a no-fee 2% card ahead of a headline-rate card.
- Redemption value. Cash back is worth its face value. Points are worth whatever the redemption gives you, which is often less than the advertised cent-per-point.
- Category caps and activation. Rotating categories that need quarterly activation are worth nothing in a quarter you forget.
- Spending more to earn more. The most expensive mistake. Earning 2% by spending an extra dollar is a 98 cent loss.
How to work out your own number
- Take your actual monthly card spend from a statement, not an estimate.
- Multiply by the flat rate for a simple card, or split by category for a tiered one.
- Multiply by 12 and subtract any annual fee.
- Compare that to what a no-fee 2% card would earn on the same spending.
Sign-up bonuses are where the real money is
Ongoing rewards are a few hundred dollars a year. A single sign-up bonus frequently exceeds an entire year of earning, which changes how to think about card choice: the bonus is usually the largest one-off return available, and the ongoing rate is what matters afterwards.
Bonuses require minimum spend inside a window. Spending more than you otherwise would to reach it converts a bonus into a loss. Only chase one you would hit on normal spending.
Comparing two cards properly
Put both on the same spending and subtract the fees. On $2,000 a month:
| No-fee 2% card | $95-fee card at 3% on some categories | |
|---|---|---|
| Annual rewards | $480 | Depends entirely on category mix |
| Annual fee | $0 | $95 |
| Net if half your spend hits 3% | $480 | $600 minus $95 = $505 |
| Net if a quarter hits 3% | $480 | $540 minus $95 = $445 |
The fee card wins only if enough of your real spending lands in its bonus categories. That is an empirical question about your statements, not a judgement about the card.
The behavioural cost nobody prices
Research on payment methods consistently finds people spend more when paying by card than cash, and rewards add a further nudge to route spending through the card. If a 2% return encourages even a 3% increase in spending, the reward is negative.
The defence is simple and boring: a fixed budget that does not change with the payment method, and autopay set to the full statement balance so the card behaves like a debit card with a rebate.
A sensible setup for most people
- One no-fee flat-rate card as the default for everything.
- Autopay the full statement balance, not the minimum.
- Add a second card only if a specific category is a large share of your spending.
- Revisit annually, and cancel or downgrade a fee card whose benefits you did not use.
Rather than closing an old card outright, ask about downgrading to a no-fee version of the same account. That keeps the account age and the credit limit, which both help your score.
Frequently asked questions
Is cash back better than points?
It is simpler and its value is certain. Points can be worth more with specific redemptions, and can also be devalued by the issuer without notice.
Do rewards count as taxable income?
Rewards earned by spending are generally treated as a rebate rather than income. Sign-up bonuses that require no spending can be treated differently. Ask a tax professional about your situation.
Is an annual fee ever worth it?
When the benefits you actually use exceed the fee. Work it out with your real spending rather than the marketing.
Does opening a rewards card hurt my credit?
A small, temporary dip from the hard inquiry, usually offset over time by the extra available credit lowering your utilization.
Do rewards expire?
Cash back on most flat-rate cards does not, while points programs often have expiry or forfeiture rules, particularly if the account closes. Check the terms.
Is it worth opening a card just for the bonus?
It can be, if you meet the spend naturally and pay in full. Repeatedly opening accounts adds inquiries and lowers your average account age, so it is not free.
What happens to rewards if I close the card?
Unredeemed rewards are commonly forfeited on closure. Redeem first, then close.
Are store cards worth it for the discount?
The upfront discount is real, and the APRs are typically high and the utility narrow. They make sense only if you pay in full and shop there often.
