Are Credit Card Rewards Worth It? Run the Break-Even

Credit card rewards are one of the few consumer products where the arithmetic is genuinely favorable for some people and genuinely predatory for others, using the identical card, on the identical terms. The variable isn't the card. It's whether you pay the statement balance in full.

So before anything else, one number. The Federal Reserve's G.19 release put the average rate on credit card accounts assessed interest at 22.15% in the second quarter of 2026. A 2% cash back card returns two cents per dollar spent. A 22.15% APR charges roughly twenty-two cents per dollar carried for a year. If you carry a balance, the rewards program is a rounding error inside a much larger bill.

The three currencies

Cash back is the only one with a fixed, knowable value. A dollar of cash back is a dollar. It doesn't expire in a way that surprises you, and nobody can quietly reprice it.

Points issued by a bank sit in the middle. They're often worth one cent each toward statement credits or a travel portal, and sometimes more when transferred to an airline or hotel program. That "sometimes more" is the entire pitch of the premium card market, and it depends on a partner program the bank doesn't control and you can't audit.

Miles and hotel points are the most volatile. The CFPB's May 2024 issue spotlight on credit card rewards analyzed several hundred consumer complaints and identified four recurring themes that ended with people not getting the rewards they were promised: unexpected promotional conditions, devaluation, redemption problems, and revocation. On devaluation specifically, the Bureau described issuers and merchant partners reducing the value of rewards consumers had already earned by increasing the number of points or miles needed for a redemption.

That last mechanism has no equivalent in cash. Nobody can announce that your $400 of cash back is now worth $310. They can absolutely do it to 40,000 miles.

Treat unredeemed points like a gift card from a company with a shaky balance sheet: fine to hold briefly, foolish to hoard. The CFPB also found nearly 1 in 10 dollars consumers earn in rewards is tied to sign-up bonuses — which are, by design, one-time.

The break-even math on an annual fee

An annual fee is not automatically bad. It's a subscription, and subscriptions have a break-even point you can calculate in about ninety seconds.

The formula: annual fee ÷ (rewards rate on the fee card − rewards rate on the best no-fee card you'd otherwise carry) = the annual spending required to break even.

Work it. A card charges $95 a year and returns 3% on dining and groceries. Your alternative is a no-fee card returning 2% on everything. The incremental rate is 3% − 2% = 1%, or one cent per dollar.

$95 ÷ 0.01 = $9,500 of spending in those categories per year. That's $792 a month on dining and groceries, every month, before the fee card beats the free one by a single dollar.

If you spend $400 a month in those categories, the math runs: $4,800 × 1% = $48 of extra rewards against a $95 fee. You are paying $47 a year for the privilege of earning rewards.

Two adjustments people forget. First, count credits only if you'd have spent the money anyway — a $120 credit for a service you don't use is worth zero, not $120, and a $120 credit for something you already buy is worth the full $120. Second, if the fee card's category bonus applies to spending you'd only do because of the bonus, it isn't a reward, it's a discount on an expense you invented.

The number that erases everything

Here is the same spending, run two ways.

Case A. You spend $2,000 a month on a 2% cash back card and pay the statement balance in full. Annual rewards: $2,000 × 12 × 0.02 = $480. Interest paid: $0, because the grace period holds. Net: +$480.

Case B. Same $2,000 a month, same 2% card, but you carry an average balance of $5,000 across the year at 22.15%. Annual rewards: still $480. Annual interest: $5,000 × 0.2215 = roughly $1,108. Net: −$628.

The rewards program did its job perfectly in both cases. In the second one, you paid $1,108 to collect $480, and the card did exactly what the issuer expected. The CFPB has said plainly that consumers who carry revolving balances often pay far more in interest and fees than they get back in rewards.

There's a compounding detail that makes Case B worse than it looks. The CFPB explains that once you lose the grace period by not paying in full, you're charged interest on the unpaid balance and also on new purchases starting the day each purchase is made. And if you pay in full some months and not others, you can lose the grace period for the month you missed and the month after. So the rewards-earning purchases in Case B start accruing interest immediately, at the register.

When rewards chasing costs more than it returns

• You spend more because the card is earning. The industry has a name for this and it is not a secret. If a 5% category bonus moves your grocery spending from $600 to $750, you earned $37.50 and spent an extra $150.
• You open cards for sign-up bonuses on a file that can't absorb the inquiries. The CFPB notes scoring models look at how recently and how frequently you apply for credit; a mortgage application eighteen months out makes this a genuinely expensive hobby.
• You hold points instead of redeeming them. Devaluation is a real, documented mechanism, and the loss lands on the balance you were saving.
• You keep an annual-fee card out of inertia. Two years past the point where the math worked is $190 nobody noticed.
• You choose a card by its rewards and inherit its APR. The CFPB's data from the January-to-June 2023 card terms survey found median purchase APRs at the 25 largest issuers ran 22.99% even for the 'great credit' tier of 720 and above — and eight to ten percentage points lower at small banks and credit unions across every tier.

The honest negative: some people should not have a rewards card at all

If you have ever revolved a balance you didn't plan to, the correct rewards rate for you is 0%, and the correct card is whichever one has the lowest APR you can get. That isn't a moral judgment about discipline. It's the same arithmetic as above with the sign flipped: the interest you avoid is guaranteed and untaxed, and the rewards you forgo are worth about 2%.

The Federal Reserve's 2025 Survey of Household Economics and Decisionmaking found 63% of adults said they'd cover a hypothetical $400 emergency expense entirely with cash, savings, or a credit card paid off at the next statement — which means well over a third would not. If a $400 surprise would put a balance on the card, a rewards card is a mechanism for making that balance more expensive, not a benefit.

And if you're already carrying card debt, the rewards question is the wrong question entirely. This site has articles on the balance-transfer window and on escaping high-interest debt; either is worth more to you than any cash back rate ever printed.

A twenty-minute audit

1. List every card, its annual fee, and its reward rate. Most people are wrong about at least one of these.
2. For each fee card, run annual fee ÷ (its rate − your best no-fee rate) and compare the answer to what you actually spend in that category. Use last year's statements, not your estimate.
3. Check every rewards balance and redeem anything sitting idle. Unredeemed points are exposed to repricing; cash in your account is not.
4. Pull twelve months of statements and add up interest charged. If that number is anything but zero, stop optimizing rewards and go fix the balance.
5. If a fee card fails its break-even, call and ask to downgrade to the issuer's no-fee version rather than closing it. Downgrading usually keeps the account's age and its limit in your utilization math; closing removes both.
