FREQUENT FLYER GLOSSARY
What is cashback in credit card rewards?
Cashback (also written cash back) is a credit card rewards model that returns a percentage of what the cardholder spends, usually as a credit on the card account or as cash paid out. [1] Cards differ in whether they pay one flat rate on everything or a higher rate in selected spending categories, and category rates are often capped. [1]
Facts checked: 18 October 2026
Key takeaways
- Cashback is a percentage of spend rather than a currency held in a separate loyalty account; Discover describes a cash back credit card as one that earns rewards as a percentage of the amount spent. [1]
- Bonus rates usually come with a ceiling and sometimes require activation: the Discover it Cash Back card pays 5% in rotating quarterly categories up to a quarterly maximum when the cardholder activates, and 1% on everything else. [1]
- A statement credit is not the same thing as cashback. A points programme can also produce one: American Express charges the purchase to the card, deducts Membership Rewards points and applies a statement credit for the points used. [5]
What is cashback and how does it work?
Cashback is a reward calculated from the amount of a purchase, so the return rises and falls with spending rather than sitting in a separate mileage or points balance. [1] Discover groups cash back cards into three common structures: a flat rate, such as 1% or 1.5% on every purchase; rewards categories, where certain kinds of spending earn more and everything else earns less; and rotating categories, where the higher-rate categories change during the year. [1]
How the reward reaches the cardholder depends on the issuer. Discover lists statement credit, a cash deposit into a bank account, gift cards and payment for purchases as possible redemption routes, and states that redemption options vary by card issuer. [1] Because cashback is a rate applied to spend, a card with no annual fee can still pay a low flat rate, while a card with a high headline rate may restrict that rate to a capped category. [1]
How does cashback differ from points and miles?
Points and miles are programme currencies rather than a rebate on spend: American Express awards one Membership Rewards point for every dollar of spend on an eligible purchase with an enrolled card, and states that the value of points varies according to how the cardholder chooses to use them. [5] Membership Rewards points may be transferred to participating airline and hotel loyalty programmes, at a rate that varies by partner, and a transfer cannot be reversed once made. [5] The name on the card and the name on the partner loyalty account must match for the accounts to be linked. [6]
The two models can look alike on a statement, which is where confusion starts. Under Pay with Points, American Express charges the full purchase to the card, deducts the points used and then applies a statement credit to reflect them, so a purchase covered with points shows as a charge and a credit; any part not covered by points stays charged. [5] The cardholder can also redeem points for a statement credit directly, with a minimum of $1 worth of points, and that credit cannot be used to pay the Minimum Payment Due. [5] A cashback rate, by contrast, is earned from spending in the first place rather than from giving up a stored balance. [1]
Where do category caps apply?
Category rates are where most of the conditions sit, and the figures below are those published by Discover as of 18 October 2026. [1]
| Card | Bonus rate | Ceiling | Base rate |
|---|---|---|---|
| Discover it Cash Back | 5% at different places each quarter, once activated | Quarterly maximum | 1% on all other purchases |
| Discover it Chrome Gas & Restaurants | 2% at gas stations and restaurants, automatically | $1,000 in combined purchases each quarter | 1% unlimited on all other purchases |
The 2% rate on the Discover it Chrome Gas & Restaurants card applies to the first $1,000 in combined gas station and restaurant purchases each calendar quarter, with quarters beginning on 1 January, 1 April, 1 July and 1 October; purchases above the cap, and all other purchases, earn 1%. [1] Restaurant spending covers merchants classified as full-service restaurants, cafes, cafeterias, fast-food locations and restaurant delivery services, while restaurants inside or affiliated with another business, such as a hotel or retail store, and establishments classified as a bakery may not qualify. [1] Gas station purchases cover merchants classified as selling automotive fuel, whether at the pump or inside the station, plus some public electric vehicle charging stations, and stations affiliated with supermarkets, supercenters or wholesale clubs may not be eligible. [1]
The purchases must be made with merchants in the U.S., and the transaction date must fall on or before the last day of the offer or promotion. [1] For online purchases the merchant's transaction date may be the date the item ships. [1] Categories are matched using merchant category codes, so a purchase can miss the extra rate when the merchant is coded differently — a food truck billing as merchandise, for example — and the issuer states it is not responsible for the codes merchants use. [1] Rewards are added to the account within two billing periods. [1]
Limits, exclusions and expiry
- Activation and caps. The 5% rate on the Discover it Cash Back card applies only up to the quarterly maximum and only when the cardholder activates the offer for that quarter; everything else earns 1%. [1]
- What counts as a purchase. Earnings apply to net purchases, meaning purchases minus any credits or returns; cash advances, balance transfers, transfers from deposit accounts and checks used to access the account are not purchases and earn nothing. [1]
- First-year match. Discover matches all the cash back earned from account approval through the first 365 days and adds it to the rewards account within two billing periods, with no limit and no purchase minimums; the offer is for new cardholders and excludes rewards processed after the match period, statement credits, rewards transfers from deposit accounts and rewards for closed accounts. [1]
- Expiry. Discover states that rewards on its cards will not expire for the life of the account, and notes that other cards may have cash back rewards that expire. [1]
- Statement credits from points. Redeeming Membership Rewards points for a statement credit requires at least $1 worth of points, the credit cannot pay the Minimum Payment Due, and Corporate Card Members are not eligible for that redemption option. [5]
Frequently asked questions
Is cashback the same as a statement credit?
No. Cashback is a reward earned as a percentage of spending, while a statement credit is a credit applied to the card account, which a points programme can also generate when points are redeemed. [1] [5]
Does cashback expire?
On Discover cards, rewards will not expire for the life of the account, but Discover notes that other cards may have cash back rewards that expire, so the card terms decide. [1]
Do category bonuses apply to every purchase?
No. The higher rate is limited to defined categories, may require activation, and usually stops at a quarterly maximum, after which the base rate applies. [1]
Can cashback be taken as cash?
That depends on the issuer. Discover lists a statement credit, a cash deposit into a bank account, gift cards and payment for purchases among possible redemption options. [1]
