Points vs Cashback vs Miles: What Each Is Really Worth

Reward programmes are deliberately complex because complexity hides value — yours and theirs. Rewards are also close to universal: the CFPB notes that since 2019, more than 90 percent of general-purpose credit card spending in the United States has happened on rewards cards. Almost everyone is earning something. Very few people know what that something is actually worth. Here is the honest breakdown of the three currencies, starting with where the money comes from — because once you understand the funding, the rest of the design stops looking arbitrary.

Where Reward Money Actually Comes From

When you pay by card, the merchant does not receive the full ticket price. Their acquiring bank deducts a merchant service charge, and the largest single component of that charge is interchange — a fee handed from the merchant's bank to your card issuer on every transaction. Your issuer keeps part of it to cover fraud, funding and operations, and hands the rest back to you as rewards. Rewards are not a gift. They are a partial rebate of a fee the merchant already paid, and which merchants price into what everyone pays, cardholder or not.

That mechanism explains the single most confusing thing about global rewards: why the same brand pays wildly different rates in different countries. In the European Union, interchange is capped by law. Regulation (EU) 2015/751 states at Article 4 that providers "shall not offer or request a per transaction interchange fee of more than 0,3 % of the value of the transaction for any credit card transaction," with Article 3 setting a 0,2 % cap for debit. In the United States, by contrast, the Federal Reserve's Regulation II governs debit card interchange only — credit cards are not covered by it at all.

The size of that gap is visible in the Fed's own data. In its 2024 Regulation II reporting, debit transactions from capped ("covered") issuers averaged $0.23 per transaction, or 0.47% of value, while exempt issuers averaged $0.51, or 1.21% — roughly two and a half times more, on the same rails, for the same purchase. Caps compress the pool that funds rewards.

The practical consequence for you: in a capped market, no card can durably pay 2% back on general spending out of interchange alone. The money has to come from somewhere else — an annual fee, interest from people who revolve, or a co-brand partner's marketing budget. That is precisely why the generous cards outside the US are usually annual-fee products or airline co-brands, and why a flat 2% everyday cashback card is largely an American phenomenon. If someone in a capped market offers you an uncapped-looking rate, read the terms for the caps, the category exclusions, or the fee that is paying for it.

The other funding source is interest, and it deserves blunt treatment. If you carry a balance, the interest almost always exceeds the rewards by a wide margin. The UK's Financial Conduct Authority defines persistent debt as the state where customers are "paying more in interest, fees and charges than they are paying of their balance" — and estimated that firms addressing it properly could save customers up to £1.3bn a year in lower interest charges. Nobody in that position is winning on points. If that describes you, stop reading about reward currencies and go read about balance transfer cards instead.

Cashback

Cashback is the simplest and most transparent. A dollar back is a dollar, full stop. No valuation games, no blackout dates, no transfer charts. For anyone who does not want to optimise, cashback is almost always the right choice because you cannot misjudge its worth.

It has two further underrated advantages. First, it is currency-agnostic — it lands in the currency of your statement, so it never becomes stranded value in a programme you no longer use. Second, it is denominated, meaning the issuer cannot quietly reduce what you already earned. A points balance can be devalued overnight by changing the award chart. A cash balance cannot.

The trade-off is a ceiling. Cashback is normally paid at the rate the interchange pool supports, so it clusters in a narrow band. You will rarely see an outlier. That predictability is the product.

Points

Flexible bank points are worth more if you learn to use them — transferring to airline or hotel partners can yield outsized value, sometimes 1.5–2x a cash redemption. But that value only exists if you do the work of finding good transfer redemptions. Redeem points lazily, for statement credit or merchandise, and they are often worth less than plain cashback. Points reward effort.

The mechanism behind the upside is worth understanding, because it is not magic. An airline sells its miles to banks for cash, at a wholesale rate. When you transfer bank points into that airline, you are converting into a currency the airline can issue at will and price however it likes. When the airline prices a seat cheaply in miles — typically premium cabins on routes with unsold inventory — the arithmetic runs in your favour. When it prices dynamically against the cash fare, the arbitrage disappears and you are back to roughly cash-equivalent value. Transferable-points cards such as those earning Membership Rewards on the Amex Gold exist to give you optionality between those two worlds; the optionality is the asset, not the points themselves.

Two structural risks come with that optionality. Transfers are one-way and almost always irreversible, so a mistimed transfer converts flexible value into a specific airline's currency permanently. And bank points typically live in a programme account tied to your card. American Express states plainly that if you cancel and hold no other eligible Card or Checking account, the points you have not redeemed "will be forfeited immediately" — with one narrow exception on that same page, for New York Card Members, who as of 10 December 2023 "may be able to redeem for 90 days after notice of account closure". That wording was confirmed on American Express's own cancellation FAQ in July 2026. A large points balance is therefore a soft lock-in on the annual fee. Budget for that before you accumulate one.

Miles

Miles are airline-specific points. Powerful for committed flyers loyal to one alliance, frustrating for everyone else — award availability is limited, values swing, and they pressure you to keep flying one carrier. Only worth it if your travel already centres on that airline.

The core failure mode of miles is that you hold inventory in a currency whose issuer sets both the supply and the price, and has every incentive to adjust both. The CFPB has flagged exactly this, reporting that consumers describe issuers and merchant partners reducing the value of rewards already earned by increasing the number of points or miles needed for a redemption (CFPB), alongside balances vanishing on account closure and through expiration policies applied without prior notice. Treat a large mileage balance as a depreciating asset with no announced depreciation schedule. Earn towards a specific trip; do not hoard.

The Valuation Trap

Issuers advertise rewards at their best-case redemption value, which most people never hit. A "worth up to 2 cents per point" card is worth that only on optimal transfers — for typical use, value it lower and compare honestly.

The trap compounds with sign-up bonuses. The CFPB found that nearly 1-in-10 dollars earned by consumers in rewards are linked to sign-up bonuses — a large slice of total programme value that arrives once and never repeats. A card that looks brilliant in year one on a bonus-inclusive calculation can be mediocre in year two on earn rates alone. Always run the numbers twice: once with the bonus, once without. The second number is the one you will live with.

A Worked Example: One Year of Spending, Five Redemptions

The two cards below are illustrations, not real products — the rates are chosen to show how the arithmetic behaves, and no issuer is being described. Take 20,000 USD a year of card spending, split 4,000 dining, 5,000 groceries, 3,000 travel and 8,000 everything else. The method works in any currency, provided you keep the spending and the per-point valuations denominated in that same one.

A flat 2% cashback card with no fee pays 20,000 × 0.02 = 400 USD. Done, no decisions.

Now a points card charging a 250 USD annual fee, earning 4x on dining and groceries, 3x on travel and 1x elsewhere. That is (4,000 × 4) + (5,000 × 4) + (3,000 × 3) + (8,000 × 1) = 16,000 + 20,000 + 9,000 + 8,000 = 53,000 points. What those points are worth depends entirely on how you redeem them.

The break-even against the free 2% card is the number to memorise: you need 400 + 250 = 650 USD of value from 53,000 points, which is 650 ÷ 53,000 = 1.23 US cents per point. Redeem below that and the "premium" card has cost you money despite the flashier earn rate. Redeem at transfer values and it pays two to three times as much. The card did not change. Your behaviour did.

Note also what the table does not include: the effort. The business-award row assumes you found award space at a sensible price on dates you can actually travel, which is a real research task, not a formality. If you want to see what that work looks like end to end, the award-search walkthrough covers it. If you would not do it, your honest valuation is the statement-credit row.

Which Currency Behaves How

Who This Is Wrong For

Rewards optimisation is oversold. It is the wrong project for you if any of the following is true.

• You carry a balance. Interest on revolving debt dwarfs any realistic reward rate. Clear the balance first; the maths is not close.
• Your spending is low or lumpy. On modest annual spend, the difference between a good and a mediocre earn rate is small in absolute terms, and an annual fee will usually swallow it. Run the break-even calculation above with your real numbers before assuming otherwise.
• You will not redeem strategically. If you know you will take the statement credit, buy the card that pays the statement credit best. There is no shame in it and it is frequently the higher-net answer.
• You travel rarely or unpredictably. Award availability rewards flexibility. If you must travel on fixed dates in peak periods, miles and hotel points will consistently underperform their advertised value.
• You are building or repairing credit. Approval odds, reporting quality and cost matter far more than earn rate at this stage. Start with building credit from scratch.

Questions People Actually Ask at This Point

Are points better than cashback? Only if you redeem them above roughly 1.2–1.3 cents each on a fee-paying card, and above 1 cent on a no-fee card. Otherwise cashback wins. Work out your own break-even rather than accepting a headline valuation. The cashback versus travel points comparison goes further into the choice.

Should I hold points or transfer them? Hold, until you have identified a specific award you can book. Transfers are one-way, and holding keeps your value flexible against devaluation in any single partner.

Do points expire? It depends on the programme, and the more important risk is not the clock but the account. Bank points are typically forfeited if the underlying card account closes, as Amex's own terms confirm above. Closing a card is a decision about your points balance as much as your annual fee.

Is an annual fee ever worth it? Yes, when the fee buys either a materially better earn rate on categories you genuinely spend in, or credits you would have spent the money on anyway. The test is whether the fee survives contact with your actual statement, not the marketing sheet — see when annual fees are worth it for how to run that test properly.

The Simple Rule

Want zero effort and guaranteed value: cashback. Willing to learn transfers for trips: flexible points. Loyal to one airline and fly a lot: miles. Match the currency to how much effort you will actually put in — not the marketing.

If you are somewhere in the middle — happy to learn transfers but unwilling to restructure your travel around one carrier — a transferable-points card such as the Amex Gold is the usual compromise, because it lets you decide later whether a given balance becomes a flight or a statement credit. That deferred decision is the whole value proposition. Just remember to check the annual fee against the break-even arithmetic above, with your own spending, before you commit.
