Credit Card Rewards Guide for Cynics (2026)

Almost every guide to credit card rewards explains the same half of the subject: how you earn them. Multipliers, categories, sign-up bonuses, the funding mechanism. All useful, all covered — including on this site, where points versus cashback versus miles does the valuation question and cashback cards explained does the structures.

This page is about the other half, and it is the half where the money actually goes missing. Between the moment you tap and the moment a reward is irreversibly yours, there are five stages, and a reward can quietly fail at every one of them.

The five stages between the tap and the money

1. Authorisation. The terminal asks your issuer to reserve the amount. This is a hold on your credit line, not a completed transaction. Nothing has moved and, for most programmes, nothing has been earned.

2. Settlement and posting. The merchant submits the transaction, it clears, and it appears on your account as posted. This is normally the point at which a reward can be calculated at all, because until now the final amount was not known. Hotels, car hire and restaurants with tips routinely settle for a different figure from the one authorised.

3. Accrual. The issuer applies the earn rate to the posted amount, using the merchant's category to decide which rate applies. This is where a purchase you thought was a bonus category turns out not to be.

4. Statement. The accrued rewards are added to your balance at the end of the cycle. Many programmes only make rewards redeemable after this point, which is why an app can show a number you cannot yet use.

5. Redemption. You convert the balance into a statement credit, a transfer, or a booking. Only here does the value become fixed. Everything before this is an entry in someone else's ledger.

The single most useful habit in this whole article follows directly from that list: a reward is provisional until it is redeemed. Every mechanism below is a way that a provisional reward becomes a smaller one.

Pending is not earned

The most common support question about rewards is why a purchase is not showing. The answer is usually stage one: the transaction is authorised, not settled.

That gap matters in three specific situations, and they are the expensive ones.

• Deposits and holds. A hotel or car hire firm authorises an estimate, then settles a different amount days later. The reward, when it comes, is calculated on the settled figure.
• Month-end and bonus deadlines. If a minimum-spend window closes on the 30th and the merchant settles on the 2nd, the purchase may land in the wrong window entirely. This is how people miss a bonus with money genuinely spent in time. Make the qualifying spend early in the window, never on the last day.
• Refunds in flight. A purchase that settles and is then refunded takes its reward with it.

Refunds, returns and the reward that goes backwards

If a purchase is refunded, disputed successfully, or otherwise reversed, the reward earned on it is generally reversed too. This is not a penalty; the transaction the reward was paid on no longer exists.

It becomes a real problem in one pattern in particular: buying something expensive to hit a minimum spend and then returning it. The spend is undone, the reward on it is undone, and if the return drops you below the bonus threshold the bonus can be undone as well. The rule we give in hitting a sign-up bonus without burning cash is the one that survives this — only ever count money you were going to spend anyway, on things you are going to keep.

It is worth knowing the direction the protection runs, too. Card networks and consumer-credit law give you real leverage against a merchant who will not resolve a dispute; they give you nothing at all against a rewards programme reversing an accrual on a transaction you cancelled yourself. The dispute rights are covered in chargebacks, Section 75 and Regulation Z; the reward reversal is simply the arithmetic correcting itself.

The merchant category code decides what counts

Here is the mechanism behind the second most common complaint: a purchase that obviously belongs in a bonus category did not earn the bonus rate.

Issuers define bonus categories by the merchant's category code — a classification attached to the business, not to your basket. It describes what the merchant is, and it is not chosen by you, by the till, or by what you bought. The practical consequences are consistent everywhere:

• A supermarket concession inside a department store can code as the department store.
• A warehouse club, a delivery platform and a petrol station with a shop attached each code as themselves, not as the groceries you bought there.
• A travel agent, an airline and an online travel platform can code differently from one another for what is functionally the same booking.
• Paying through an intermediary — a wallet, a marketplace, a bill-pay service — can change the code your issuer sees entirely.

Your issuer's own terms are the only document that states which codes qualify, and issuers vary. Two things follow. First, ask for that list in writing before you build a strategy on a category. Second, test it cheaply: make one small purchase at the merchant, wait for it to post, and read what actually accrued. One small transaction settles the question permanently; a year of assuming does not.

How a cap is actually measured

A capped bonus rate is not one design, it is several, and they behave very differently on identical spending. The measurement basis is usually in the terms and almost never in the headline.

That last row is not an accident of design. A category that requires quarterly activation is priced on the assumption that a meaningful share of holders will not activate, and the ones who forget are subsidising the ones who do not.

A worked example: the same spending, two cap designs

Take 12,000 a year of grocery spending, unevenly distributed — 1,500 a month for eight months, and 0 for four. Two cards, both advertising the same headline.

Card A: 4% on groceries, capped at 500 of spending per statement cycle, 1% thereafter. In each of the eight active months, 500 earns 4% (20) and 1,000 earns 1% (10), so 30 a month, 240 a year. The four empty months earn nothing and the unused cap does not carry forward. Blended rate on 12,000: 2.0%.

Card B: 4% on groceries, capped at 6,000 of spending per calendar year, 1% thereafter. The first 6,000 earns 4% (240); the remaining 6,000 earns 1% (60). Total 300. Blended rate: 2.5%.

Same headline rate. Same spending. A 60 difference, entirely from how the cap is measured — and the second card wins precisely because this spender's pattern is lumpy. Reverse the pattern to a flat 1,000 a month and the gap narrows sharply.

The instruction that comes out of this is short: never compare headline rates. Compute the blended rate against your own twelve months of spending. Our rewards calculator does the arithmetic; three months of statements is enough input to get the shape right.

Expiry, forfeiture and what happens when the account closes

Three separate clauses decide whether a balance survives, and they are usually in three different places in the terms.

Expiry on a timer. Some balances expire a fixed period after they are earned. Where this exists it is generally stated plainly, and it is the easiest of the three to plan around.

Expiry on inactivity. More common and much easier to trip. The clock is reset by activity on the account rather than by earning, so a card left in a drawer can lose a balance that was never going anywhere.

Forfeiture on closure. The one that costs the most, because it interacts with a decision people make for unrelated reasons. Closing an account — or having it closed for you — commonly forfeits an unredeemed balance outright. If you are considering dropping a card because the annual fee no longer earns its keep, redeem the balance first and read why downgrading beats closing before you call.

The defence against all three is the same, and it is not loyalty. It is liquidity. Redeem regularly. A balance you can spend this year at today's rate is worth more than a larger balance under next year's rules.

The exchange rate you never see

A cashback balance is denominated in money and cannot be repriced. A points balance is denominated in a unit the issuer or its partner programme controls, and the number of points a redemption costs is set by them — after you earned it.

The regulator has looked directly at this. The CFPB's rewards issue spotlight documents consumers reporting rewards devalued, revoked, or made harder to redeem than the marketing implied, and its Circular 2024-07 of 18 December 2024 warns operators that materially reducing the value of rewards consumers have already earned, or revoking them on vague conditions, can be unfair or deceptive.

Read that as a description of the asset class rather than as an accusation. A points balance is an unindexed, revocable claim on a company with a commercial incentive to reprice it. That is not a reason to refuse points — transferable points can be worth considerably more than cash to somebody who redeems them well, and turning everyday points into premium travel is how that is actually done. It is a reason not to treat a balance as savings.

Where the money comes from, briefly

Rewards are funded largely out of interchange — the fee the merchant's bank pays your issuer on each transaction — and the size of that pool is set by regulation. The EU caps consumer interchange at 0.2% for debit and 0.3% for credit; the Federal Reserve's Regulation II caps debit interchange only, leaving US consumer credit uncapped. That single asymmetry is why American rewards cards can advertise multipliers that a European issuer structurally cannot fund.

That is the whole of it here, deliberately. The mechanism is set out properly in interchange fees: who pays for rewards, and repeating it at length is exactly what made this page redundant against four of its own neighbours.

What to check, and what to ask

Six answers, all obtainable from your issuer, that decide more of your return than the earn rate does.

1. When does a reward move from pending to posted, and does the earn date or the posting date determine which promotional window it falls in?
2. Which merchant category codes qualify for each bonus category? Ask for the list, in writing.
3. How is the cap measured — statement cycle, calendar quarter, calendar year, or anniversary year?
4. Does anything require activation, and does it repeat?
5. What expires, and on what trigger — a timer, inactivity, or account closure?
6. What happens to the balance if I close, downgrade, or am closed?

Who this is wrong for

The honest limits, because a lifecycle this fiddly is not worth managing for everyone.

If you carry a balance, none of it matters. The Federal Reserve reports the average rate on US commercial bank credit card plans at 20.94% across all accounts and 22.15% on accounts assessed interest. At those rates one month of unplanned carry costs more than a year of optimisation returns, and the grace period — which the CFPB defines as "the period between the end of a billing cycle and the date your payment is due" — is the only thing keeping that at zero.

If your spending is small or flat, the difference between a well-managed and a badly-managed rewards card is tens of units a year. That is real, and it is not worth reading your terms quarterly for.

If most of your spending is in another currency, the rewards question is the wrong question. A card charging 3% abroad while paying 2% back returns minus 1% on every foreign purchase, and no cap design fixes that. Keep the rewards card for domestic spending and hold a low-cost multi-currency card such as Wise for anything denominated elsewhere.

And the genuine counter-argument: an ordinary person who puts everything on one decent flat-rate card, pays in full, and redeems once a year captures most of the available value with none of this administration. The lifecycle mechanics above are worth managing when the sums are large — a business routing supplier invoices through a service such as Melio, or a household with heavily concentrated category spending. Below that, the simple version is not a compromise. It is the correct answer.

The bottom line

Earning a reward is the easy part and the only part the marketing describes. What decides your actual return is what happens next: whether it posts, whether it survives a refund, whether the merchant coded the way you assumed, how the cap is measured, and whether the balance is still worth what it was when you earned it.

Redeem regularly. Test a category before you build on it. Compute a blended rate against your own spending rather than trusting a headline. And pay the statement in full, because every calculation on this page collapses at 22% interest.
