Blue Cash Preferred® Card from American Express Review: The Highest-Paying Supermarket Card in America

Who should get the Blue Cash Preferred — and who should skip it

Four things decide this: whether you have ever transferred points, whether you were buying it for a specific transfer partner, whether you are under 5/24, and — the one that overrides the other three — whether you carry a balance.

This is a family card, and the arithmetic is unusually easy to run yourself: multiply your annual supermarket spending by the elevated rate, cap it at the annual ceiling, add the streaming and transit earning, and compare to the fee. If your grocery bill is large and goes to a regular supermarket, it wins by a wide margin. If it is not, it does not, and no amount of optimization changes that.

It fits alongside a travel card rather than instead of one. Cash back is not a currency you can transfer, so this card is the earning engine for the food budget while a transferable-points card handles travel and dining out.

Skip it if your food shopping happens at a warehouse club, a superstore or a delivery service — none of them reliably code as supermarkets. Skip it too if you would rather have points with a redemption ceiling; the cash back here is worth exactly its face value and never more.

What is the Blue Cash Preferred welcome offer worth?

The offer is a statement credit, and the number that matters is not the headline — it is what the headline converts to at a redemption value we publish and defend. Here is the whole calculation.

The current offer

$300 after you spend $3,000 on purchases in the first 6 months from account opening, paid as Reward Dollars, redeemable as a statement credit or at Amazon.com checkout. The issuer writes the offer as a ceiling and states that welcome offers vary and that you may not be eligible for one^†

The welcome offer is paid as a statement credit rather than in points, which makes its value unambiguous — there is no valuation to argue about and no redemption skill required.

The requirement runs over a six-month window at a modest level, so it is one of the easiest bonuses in our set to earn without changing anything. The catch is the once-per-lifetime rule: having held this card before disqualifies you.

How fast does the Blue Cash Preferred earn?

The multiplier is only half of an earn rate. The other half is what the currency is worth, and a high multiplier on a weak currency loses to a low multiplier on a strong one. The right-hand column below is the one to read: it multiplies each rate by our published valuation to give what a dollar of spending in that category actually returns.

Everything outside those categories earns 1%, which is 1.0¢ back per dollar at our valuation. That is the rate most of a normal household’s spending earns, so it deserves more weight than the headline multiplier when you compare cards.

The supermarket rate is the reason to hold the card and the cap is the reason to check your own numbers first. Once annual supermarket spending crosses the ceiling, every subsequent grocery dollar earns the base rate, so a very large family can find the card’s effective rate is far below the headline by autumn.

The streaming and transit categories are the quiet value. Both are recurring bills that earn at an elevated rate with no decision required, and transit is defined broadly enough to include rideshare, tolls, trains and parking.

Fuel earns at a middling rate and everything else earns the base rate. This card should not carry your general spending.

What are the Blue Cash Preferred perks actually worth?

Issuers publish a benefits total that assumes you claim every credit, in the right channel, in the right month, every year. Almost nobody does. So we discount each credit by how hard it is to claim, and we publish the discount rather than the conclusion — if you think a discount is wrong for your own habits, the table gives you everything you need to redo the arithmetic yourself.

These benefits carry no dollar value in our model, either because they are insurance that pays only on a claim or because their value depends entirely on circumstances we cannot generalize. They are real, and they are excluded from the arithmetic above deliberately — counting them would let us inflate the card’s value without evidence.

• Return protection. Amex will refund eligible purchases the merchant will not take back, within a limited window and per-item cap.
• Purchase protection and extended warranty. Coverage against damage or theft on eligible new purchases, plus additional warranty coverage.
• Car rental loss and damage insurance. Secondary coverage on eligible rentals charged to the card, underwritten by AMEX Assurance Company and subject to its own exclusions.
• Global Assist Hotline. Coordination and referral services more than 100 miles from home. The service itself costs nothing; the third-party providers it refers you to do not.
• Amex Offers. Targeted merchant credits added to the account throughout the year. Value varies widely by cardholder, so we assign none.
• American Express Venue Collection concessions credit. Statement credits worth 10% back on food and drink at participating stadiums and arenas, capped per calendar year, on one enrolled card. Carried at no value in our model: it is a dated promotion that ends December 31, 2026, not a recurring benefit you can count on in year two.

Both credits attached to this card are merchant-specific subscriptions, and we discount them harder than almost anything else we model. The entertainment bundle credit only pays if you subscribe to a specific package; the meal-kit credit only pays if you have an active subscription to one particular service.

The genuinely useful protections are the unglamorous ones: return protection, purchase protection and extended warranty. They cost nothing to have and occasionally pay for the fee in one claim, but they are not a reason to choose the card.

The introductory fee waiver in year one changes how you should evaluate this card. Judge it on year two, when the fee is real, and use year one to measure what your actual grocery spending returns.

What the card really costs each year

This is the number to compare across cards, and it is the one almost nobody publishes: the annual fee minus the credits a realistic person claims. A negative figure means the card pays you to keep it.

The fee is reduced in the first year, so year one and year two are different products. The figure above is the ongoing cost; the first-year fee is $0 against an ongoing $95, which is why the retention question below matters more on this card than on most.

How do you redeem Cash Back?

Redemption is a statement credit and nothing else. That is the point: there is no currency to value, no transfer partner to research, no devaluation risk, and no way to redeem badly.

The consequence is a hard ceiling. Cash back is worth what it says and never more, so a household that would enjoy learning transfers will find the same grocery spending produces materially more value on a points card with a strong partner list — at the cost of having to do the work.

If you want both, the answer is two cards: this one for the supermarket run, a transferable-points card for everything else.

Our rating, axis by axis

Every card in the Award Rate database is scored on the same five axes, by the same people, before any commercial arrangement is considered. The rationale below is the reasoning, not a summary of the number.

Is it worth keeping in year two?

Year two is the decision, because the fee starts then. Take your first-year supermarket total from a statement, apply the cap, and check whether the earning beats the fee against a no-fee flat-rate card. If it is close, the credits will not save it — our discounts on them are heavy for good reason.

What to consider instead of the Blue Cash Preferred

These are the cards we would genuinely put in front of the same reader. Sort the table by whichever column is binding for you — net annual cost matters if you are fee-sensitive, first-year value if you are optimizing a single year.

The card we score highest here is not the one you clicked on: it is the Sapphire Preferred. The badge on the Blue Cash Preferred row says Reviewed here rather than Our pick because that is all it means — it marks the subject of this page, not a recommendation. Our scores are set before any commercial arrangement is considered, and we would rather publish the contradiction than hide it: if the rating column disagrees with the page you landed on, the rating column is the one to read.

Amex Gold

Wins if you also eat out often and want points you can transfer, and if you will run its monthly credits like errands. Read the full Blue Cash Preferred vs Amex Gold comparison.

Freedom Unlimited

Wins if you want no annual fee and a flat rate, particularly if you already hold a Sapphire card that turns the same points into airline miles.

Sapphire Preferred

Wins if what you actually want is travel rewards rather than a grocery rebate.

Will you be approved? The rules that get people declined

Being declined is the reader’s real risk on this page. A rejection costs a hard inquiry and leaves you with nothing, and in almost every case the reason is an issuer rule rather than your credit score. American Express applies the following to this card. None of them are published as policy, and none of them have an appeal.

Credit profile expected by American Express for this product: Good to Excellent (690+). A score inside that band does not guarantee approval, and nothing on this page should be read as a prediction of one — issuers weigh income, existing exposure and account history alongside the score.
