The Blue Cash Preferred Card from American Express is built around one number: 6% cash back at U.S. supermarkets, the highest published grocery rate on any mainstream cash back card. The price of that rate is a $0 intro annual fee for the first year, then $95 — which means from year two onward, the card has to out-earn a crowded field of no-fee competitors by at least $95 before it earns you anything at all.
The short version: if your household runs roughly $265 a month or more through actual U.S. supermarkets — or a smaller grocery bill plus streaming subscriptions and a transit commute — the Preferred clears its fee with room to spare. Below that line, its no-annual-fee sibling quietly wins. This review works through the math, the category fine print that catches people off guard, and the spending profiles that should skip the card entirely.
Where the 6% Applies — and Where It Stops
The headline rate comes with both a cap and a definition. Per the card’s official terms, you earn 6% cash back on the first $6,000 of eligible purchases per calendar year at U.S. supermarkets, then 1% after that. At $500 a month in groceries you exhaust the cap in exactly twelve months; anything beyond it earns the same 1% as general spending.
The definition matters just as much as the cap. Amex’s terms exclude superstores, convenience stores, warehouse clubs, and meal-kit delivery services from the supermarket category — groceries rung up at Costco, Walmart, or Target earn 1%, not 6%. If a warehouse club handles most of your food spending, this is the wrong card; our guide to credit cards for Costco shoppers covers combinations that fit that pattern better.
Beyond the grocery aisle, the card earns 6% on select U.S. streaming subscriptions, 3% on transit, 3% at U.S. gas stations, and 1% on everything else. Transit is defined generously — taxis, rideshare, parking, tolls, trains, buses, ferries, and subways all count. Streaming has its own catch: a subscription billed through a third party, such as a cable provider or an app-store bundle, may not qualify. Rewards arrive as Reward Dollars redeemable for statement credits or at Amazon checkout; this is a pure cash back card, so there are no transfer partners or award charts to study.
The $95 Math at Three Grocery Budgets
Here is what the card actually returns at three realistic grocery budgets from year two onward, once the $95 fee applies. The right-hand column shows the no-fee Blue Cash Everyday, which earns 3% at U.S. supermarkets on the same $6,000 annual cap — the comparison that decides this card for most people.
| Supermarket spend | Blue Cash Preferred (6%, after $95 fee) | Blue Cash Everyday (3%, no fee) |
|---|---|---|
| $250/month — $3,000/yr | $85 | $90 |
| $450/month — $5,400/yr | $229 | $162 |
| $700/month — $8,400/yr | $289 | $204 |
Two things stand out. First, the grocery-only break-even against the Everyday sits near $264 a month: below that, the no-fee card wins outright, as the first row shows. Second, because both cards cap the category at $6,000 a year, the Preferred’s grocery advantage tops out at $180 a year — $85 after the fee — no matter how much you spend. Groceries get the card to the starting line; the other categories decide whether it wins.
The one-line test
The Preferred out-earns the no-fee Everyday by 3 cents per supermarket dollar (up to $6,000 a year) and 5 cents per eligible streaming dollar. Add those two numbers for your own spending. If the total clears $95 comfortably, the fee pays for itself; if it doesn’t, take the Everyday.
Preferred vs. Everyday: The Decision That Actually Matters
Amex itself sells the closest alternative. The Blue Cash Everyday charges no annual fee and earns 3% at U.S. supermarkets, 3% at U.S. gas stations, and 3% on U.S. online retail purchases — each on up to $6,000 a year in purchases, then 1%. It also carries a longer 0% intro APR window than the Preferred and a smaller version of the same Disney streaming credit.
| Category | Blue Cash Preferred | Blue Cash Everyday |
|---|---|---|
| Annual fee | $0 first year, then $95 | $0 |
| U.S. supermarkets | 6% (first $6,000/yr, then 1%) | 3% (first $6,000/yr, then 1%) |
| Select U.S. streaming | 6% | 1% |
| Transit | 3% | 1% |
| U.S. gas stations | 3% | 3% (first $6,000/yr, then 1%) |
| U.S. online retail | 1% | 3% (first $6,000/yr, then 1%) |
| Disney streaming credit | Up to $120/yr ($10/month) | Up to $84/yr ($7/month) |
| Intro APR on purchases and balance transfers | 0% for 12 months, then variable | 0% for 15 months, then variable |
The Everyday’s online retail category is the one place it beats its sibling: a household that spends more at Amazon than at the supermarket may earn more with the free card. In the other direction, streaming and transit are pure Preferred territory — a $60-a-month streaming stack adds about $36 a year to the Preferred’s side of the ledger, and a daily transit commute widens the gap further. If your spending splits across several categories, our guide to the best grocery cards shows how the Preferred stacks up against issuers beyond Amex.
The Disney Credit, the Intro APR, and the Fine Print
The card’s one recurring credit is easy to overlook and can nearly cancel the fee by itself: enroll and pay for a subscription directly at DisneyPlus.com, Hulu.com, or Stream.ESPN.com and Amex rebates up to $10 a month — up to $120 a year. The purchase has to be made on those U.S. websites; a subscription bought through a third-party device or platform does not trigger the credit. If you already pay for any Disney service, that is $120 of the $95 fee gone before groceries enter the picture — and if streaming drives your card choice generally, our streaming and subscriptions comparison ranks this card against its competitors.
New cardholders also get a financing window: 0% intro APR on purchases and balance transfers for 12 months from account opening, then a variable APR of 19.49% to 28.49%. As for the welcome offer, Amex currently advertises as high as $300 back after $3,000 in purchases in the first six months — but offers vary by applicant and you see your actual number only when you apply, so confirm the terms on the issuer’s page rather than planning around the headline figure.
One caution for travelers: the card charges a 2.7% foreign transaction fee on purchases made abroad. It is a card for the supermarket run, not the trip overseas — leave it home and carry a no-foreign-transaction-fee card instead.
The Verdict on the $95 Grocery Card
The Blue Cash Preferred is worth it for households that buy groceries at actual U.S. supermarkets to the tune of $265 a month or more, and it is decisively worth it for households that add streaming subscriptions or a transit commute on top. A family spending $450 a month on groceries with a couple of streaming services earns roughly $100 a year more than the best no-fee alternative — real money for zero effort.
It is not worth it for warehouse-club and superstore shoppers, for anyone whose online spending dwarfs their supermarket bill, for international use, or for anyone who wants transferable travel points rather than cash. And because the first year costs nothing, the decision is not a leap: put the card through a full year of your real spending, look at what it earned by the time the $95 fee is about to post, and keep it only if the math from this review held up. Rates, credits, and offers change — verify current terms on the American Express site before applying.
Frequently Asked Questions
At 6% back, the fee is covered by $1,584 a year — about $132 a month — at U.S. supermarkets. The more useful threshold is roughly $264 a month, the point where the Preferred starts beating the no-fee Blue Cash Everyday on groceries alone.
No. The card’s official terms state that superstores, convenience stores, warehouse clubs, and meal-kit delivery services are not considered supermarkets, so purchases there earn 1%.
The rate drops to 1% on supermarket purchases for the rest of the calendar year, then the $6,000 cap resets. The 6% streaming, 3% transit, and 3% gas categories are not part of that cap.
American Express advertises an offer of as high as $300 back after $3,000 in purchases in the first six months, but welcome offers vary by applicant and you may not be eligible — Amex shows your specific offer during the application before you accept the card.
