American Express Blue Cash Preferred

Advertiser disclosure: We may earn a commission if you’re approved for a card through links on this page. It doesn’t change what we recommend or what you pay. Rates and offers are current as of June 2026 and change often, so confirm the details on American Express’s site before you apply.

Last week our grocery receipt hit $214 for what felt like three bags and a rotisserie chicken. That’s the moment a card like this earns its keep. The American Express Blue Cash Preferred pays 6% cash back at U.S. supermarkets, and on a bill like that, you’re looking at almost thirteen bucks back from one trip.

But there’s a $95 annual fee waiting after the first year, and that 6% rate doesn’t run forever. So the real question isn’t whether 6% sounds good. It does. It’s whether your household spends enough on groceries to turn that headline rate into more cash than the fee costs you. Let’s do the actual arithmetic.

You can pull up the full terms on the official Amex Blue Cash Preferred page while you read.

The Welcome Offer

Right now Amex is offering a $250 statement credit after you spend $3,000 in eligible purchases in your first 6 months. Some application channels surface a higher offer (we’ve seen $300 floating around), and Amex is famous for showing different offers to different people, so it’s worth checking your personalized offer before you commit.

That $3,000-in-6-months requirement breaks down to $500 a month, which a grocery-heavy household clears without trying. Offers like this change constantly and aren’t guaranteed to every applicant, so confirm the current terms on Amex’s site before you apply rather than taking our number as gospel.

One nice extra during that window: there’s a 0% intro APR on purchases and balance transfers for the first 12 months from account opening. After that it reverts to a variable 19.49% - 28.49% APR depending on your credit. That intro rate is a genuine cushion if you’ve got a big planned purchase, but don’t treat it as free money. The day month 13 hits, that balance starts costing you real interest.

How You Earn Cash Back

Here’s the full earning structure, and the catch on each one:

The supermarket cap is the part people gloss over. 6% applies to your first $6,000 in grocery spending each year, which works out to $500 a month. Spend past that and you’re earning a plain 1% on the overflow. So the absolute most you’ll pull from the 6% bucket is $360 a year before the rate steps down.

That cap also has a definition problem worth knowing. “U.S. supermarkets” means stores Amex classifies as supermarkets. Warehouse clubs like Costco and big-box stores like Walmart and Target usually code as something else, so groceries bought there earn the 1% base rate, not 6%. If you do most of your food shopping at Costco, this card is the wrong tool.

The Disney Streaming Credit

Amex quietly improved one perk that’s easy to miss. The card now carries a Disney streaming credit worth up to $120 a year, doled out as up to $10 per month in statement credits on eligible Disney+, Hulu, ESPN, or HBO Max charges. Enrollment is required, and credits change over time, so confirm it’s still active when you sign up.

If you already pay for one of those services, that’s $120 that lands straight back in your account annually. On its own it more than covers the $95 fee. We’ll be honest though: a credit only counts if you’d spend the money anyway. Don’t subscribe to Disney+ just to “save” $10.

Let’s Do the Real Math

Forget the marketing and run your own numbers. Here’s a typical family that spends $700 a month on groceries plus some streaming and gas:

Subtract the $95 fee and that household nets roughly $505 a year. That’s a clear win. Now shrink it: a single person spending $250 a month on groceries earns about $180 at 6%, and once you net out the fee, the math gets thin fast. The card rewards volume. The more you feed, the better it pays.

Who Should Get This Card

The Blue Cash Preferred is a strong pick if you:

• Feed a household and spend $400 or more a month at actual supermarkets
• Pay for streaming that lands on Amex’s eligible list, especially Disney’s services
• Want simple cash back with no points to track or transfer partners to study
• Pay in full every month so the rewards aren’t eaten by interest

Who Should Skip It

Be honest and pass on this card if:

• You shop at Costco or Walmart for groceries. Those code outside the supermarket category and earn 1%, killing the whole point.
• You’re a light grocery spender. If you can’t put a few hundred a month through it, the $95 fee outruns your rewards.
• You carry a balance. A 19.49% - 28.49% variable APR wipes out 6% cash back in a hurry. Cash back cards only work if you pay in full.
• You want one flat-rate card for everything. This one’s built around categories, not general spending at 1%.

Blue Cash Preferred vs. Blue Cash Everyday

The comparison most people should make is against Amex’s own no-fee sibling, the Blue Cash Everyday. It charges $0 annually and pays 3% at U.S. supermarkets (on up to $6,000/year), 3% on U.S. online retail, and 3% at U.S. gas stations.

The Preferred only pulls ahead once your grocery spending is high enough that the extra 3% beats the $95 fee. The break-even is roughly $3,200 a year in supermarket spending (about $265 a month), where the extra 3% adds up to the fee. Below that, the free Everyday card wins. Above it, especially with the streaming credit, the Preferred earns its keep. If you’re squinting at the math, that closeness is your answer: take the Everyday and skip the fee.

If groceries aren’t your biggest line item, it’s worth seeing how this stacks up against the flat-rate options in our best cash back credit cards roundup before you decide.

Frequently Asked Questions

Is the 6% really capped? Yes. The 6% supermarket rate applies to your first $6,000 in spending each calendar year, then drops to 1%. The most you’ll earn at 6% is $360 annually.

Does Costco count as a supermarket? No. Warehouse clubs and superstores like Costco, Walmart, and Target generally don’t code as U.S. supermarkets, so those purchases earn the 1% base rate.

Is the annual fee waived? It’s $0 for the first year, then $95 after that. Offers and fees can change, so confirm the current terms on Amex’s site before applying.

Can I really cover the fee with the Disney credit? If you already pay for an eligible Disney, Hulu, ESPN, or HBO Max subscription, the up-to-$120 annual credit more than offsets the $95 fee on its own. Enrollment is required and the credit can change.

The Bottom Line

The Blue Cash Preferred is one of the most rewarding grocery cards you can carry, but only if your shopping cart matches its rules. A family putting $500-plus a month through a real supermarket, paying for streaming, and using the Disney credit will clear the $95 fee several times over and keep a few hundred dollars a year that would otherwise vanish.

Pull up your last three grocery statements and check two things: how much you spend, and where. If the total is healthy and the store actually codes as a supermarket, this card pays you well for shopping you’d do regardless. If you’re a Costco loyalist or a light spender, the no-fee Blue Cash Everyday is sitting right there doing most of the job for free.
