The American Express Blue Card is built for people who spend heavily on groceries, gas, and online purchases
The American Express Blue Cash Preferred card returns cash on everyday categories: 6% back on U.S. supermarket purchases (up to $25,000 per year, then 1%), 1% after that; 6% on select U.S. transit (including taxis, rideshare, parking, trains, buses, and more); 1% on all other purchases. There is an annual fee of $95. The card does not earn rewards on restaurant dining, travel, or other categories outside those listed.
This card makes sense if you spend $200 or more per month on groceries and gas combined. Below that threshold, the annual fee erodes the value of the cash back. Above it, the 6% rate on supermarket and transit spending can offset the fee within a few months of regular use.
American Express is a charge card company, not a bank. That means the card issuer is American Express itself, not a partner bank. Transactions settle differently than with Visa or Mastercard, and not all merchants accept Amex — though acceptance has widened significantly in recent years.
Key Takeaways
- The card returns 6% cash back on supermarket purchases up to $25,000 per year, then 1%, plus 6% on select transit and 1% on everything else.
- The $95 annual fee means you need to spend enough in bonus categories to make the rewards worthwhile — roughly $200 per month on groceries and transit combined.
- American Express cards are issued directly by Amex, not a bank partner, and not all merchants accept them.
- The card has no foreign transaction fees, which can save money if you travel internationally and use it abroad.
- Cash back is paid as a statement credit or direct deposit, not points that expire or require redemption through a portal.
How the cash back categories work in practice
The 6% supermarket rate applies to purchases at U.S. supermarkets coded as such by the merchant. Warehouse clubs like Costco and Sam's Club, gas stations, and convenience stores do not may have access to, even if they sell groceries. Once you hit $25,000 in supermarket purchases in a calendar year, the rate drops to 1% for the rest of that year. For most households, this cap is not a practical limit — $25,000 is roughly $2,000 per month in grocery spending.
The 6% transit category includes taxis, rideshare services (Uber, Lyft), parking, trains, buses, and tolls. It does not include airline tickets or hotel stays, which earn 1%. This makes the card useful if you use public transportation or rideshare regularly but not if you primarily fly for travel.
All other purchases — restaurants, retail, utilities, subscriptions — earn 1% cash back with no cap. The 1% rate is lower than many competing cards offer in their bonus categories, so the Blue Card's value depends almost entirely on how much you spend in the 6% categories.
Annual fee and when it makes financial sense
The $95 annual fee is charged once per year. To break even, you need to earn $95 in cash back. At 6% on supermarket purchases, that means spending roughly $1,583 per year, or about $132 per month. At 1% on other purchases, you would need to spend $9,500 per year to earn $95 back.
Most households that carry this card earn the bulk of their rewards from supermarket and transit spending. If you spend $300 per month on groceries and $50 per month on transit, you earn $25.20 per month in cash back, or about $302 per year — enough to cover the fee and keep roughly $207 in net rewards annually.
If your supermarket and transit spending is under $150 per month combined, the card likely costs more than it returns. In that case, a no-annual-fee card with a flat 2% cash back on all purchases would be a better fit.
Acceptance and how American Express works differently
American Express is not a Visa or Mastercard. It is a card network and issuer combined, meaning Amex both owns the card brand and issues the card to you. This structure has two practical effects: Amex sets its own acceptance rules, and transactions are processed differently.
Amex acceptance has improved significantly in the past decade. Most major retailers, grocery stores, gas stations, and online merchants now take Amex. However, some smaller merchants, certain regional chains, and a few categories (like some utility companies) still do not. Before opening the card, check whether your regular spending locations accept it. You can search the Amex merchant locator on their website.
Amex cards are charge cards, not credit cards. This means the full balance is due each month, not just a minimum payment. If you carry a balance, interest accrues, but the expectation is that you pay in full. This is different from most Visa and Mastercard products, which allow you to revolve a balance month to month.
Foreign transaction fees and international use
The Blue Cash Preferred card has no foreign transaction fees. If you travel internationally and use the card abroad, you pay no extra charge beyond the standard Amex processing rate. This is useful if you travel regularly or live part of the year outside the United States.
The 6% supermarket and transit categories explore only to U.S. merchants. Purchases made at foreign supermarkets or transit systems earn 1%. This limits the card's value for extended international stays but does not penalize you for occasional travel.
How cash back is paid and other account features
Cash back earned on the Blue Card is paid as a statement credit or deposited directly to a bank account you link to your Amex profile. You do not need to redeem it through a points portal or wait for it to post — it appears automatically. This is simpler than cards that require you to log in and convert points to cash or gift cards.
The card includes purchase protection, meaning Amex will reimburse you for may be able to access purchases that are damaged or stolen within a certain window. It also includes extended warranty coverage on may be able to access items, adding time to the manufacturer's warranty. These protections are standard on most premium cash back cards and are not unique to Amex.
Amex offers a mobile app for tracking spending, viewing statements, and managing your account. You can also set up alerts for large purchases or unusual activity. These tools are available to all Amex cardholders at no extra cost.
Comparing the Blue Card to other cash back options
The Blue Cash Preferred competes with cards like the Chase Freedom Unlimited (1.5% on all purchases, no annual fee) and the Citi Double Cash (2% on all purchases, no annual fee). If you do not spend heavily on groceries and transit, one of these flat-rate cards will return more cash back without an annual fee.
The Blue Card also competes with the Chase Freedom Flex, which offers 5% cash back on rotating categories (groceries for the first $1,500 per year, then 1%) and 1% on everything else, with no annual fee. The key difference is that the Blue Card's 6% supermarket rate is permanent, while the Freedom Flex's 5% rate on groceries is capped at $1,500 per year and requires set up each quarter.
If you spend $400 or more per month on groceries and transit combined, the Blue Card's 6% rate usually wins. Below that, a no-annual-fee card with a flat 2% rate is likely better. The choice depends on your actual spending, not on the card's brand or prestige.
Frequently Asked Questions
Do I have to pay the annual fee every year?
Yes. The $95 annual fee is charged once per calendar year. You can cancel the card at any time to stop future fees, but the fee is not waived or refunded if you close the account partway through the year. Some cardholders cancel after the first year if they determine the rewards do not justify the cost.
What happens if I don't pay the full balance?
Interest accrues on the unpaid balance at the card's APR, which varies based on your creditworthiness. Because this is a charge card, the expectation is that you pay in full each month. Carrying a balance defeats much of the card's value, since interest charges will exceed the cash back you earn.
Can I use this card outside the United States?
Yes, but the bonus categories only explore to U.S. merchants. Purchases at foreign supermarkets or transit systems earn 1% cash back. There are no foreign transaction fees, so you will not be charged extra for using the card abroad. The card is useful for travel, but you will not earn the 6% rate on everyday purchases made internationally.
What credit score do I need to open this card?
American Express typically requires a good to excellent credit score, usually 670 or higher, though the exact requirement varies. You can check your may be able to access without a hard inquiry using Amex's pre-qualification tool on their website. A hard inquiry will appear on your credit report once you formally request the card.
Is the cash back taxable income?
No. Cash back on credit cards is treated as a discount on your purchase, not as income. You do not report it on your tax return. This applies to all cash back cards, not just Amex.
