The short answer: The Sam’s Club Mastercard earns solid rates, including 5 percent on gas, but its rewards are capped at 5,000 dollars a year, loaded onto your Sam’s membership, and redeemable only if you keep an active paid membership. The gas rate is genuinely good for Sam’s loyalists, but the cap and the membership lock make a flexible card better for most people.
Good rates, but tied to Sam’s
The Sam’s Club Mastercard from Synchrony has no annual fee beyond your Sam’s membership and earns 5 percent on gas up to a yearly cap, 3 percent on dining and travel, and 1 percent elsewhere, paid as Sam’s Cash. The gas rate is genuinely strong. The catch is that Sam’s Cash is loaded onto your Sam’s membership and can only be redeemed if you have an active membership, so the rewards are gated behind paying Sam’s.

The cap and the lock
Sam’s Cash is capped at 5,000 dollars per year across all your accounts, so high spenders hit a ceiling, and you can earn but not redeem if your membership lapses. You can use Sam’s Cash in-club, at SamsClub.com, toward your membership fee, or cash it out at a club, which is more flexible than a Costco certificate, but it still revolves around the Sam’s ecosystem and the active-membership requirement. See the Costco card takedown.
Who it suits
If you are a committed Sam’s member who buys a lot of gas and will keep the membership, the 5 percent gas rate can beat a flat card on that spending. For everyone else, a flat 2 percent cash card pays uncapped rewards every month, with no membership required and no ecosystem lock. Match the card to whether Sam’s is truly central to your life.

Frequently asked questions
Is the Sam’s Club credit card worth it?
Only for committed Sam’s members who buy a lot of gas. It earns a strong 5 percent on gas, but rewards are capped at 5,000 dollars a year, gated behind an active membership, and tied to the Sam’s ecosystem.
How does Sam’s Cash work?
Rewards are paid as Sam’s Cash loaded onto your membership, capped at 5,000 dollars per year. You can redeem it in-club, online, toward membership fees, or cash it out at a club, but only with an active Sam’s membership.
Do I need a Sam’s membership to use the rewards?
Yes. You can earn Sam’s Cash without an active membership, but you must have an active membership to redeem it, so the rewards are gated behind continuing to pay Sam’s.
Is the Sam’s card better than a flat cash card?
Only for heavy gas buyers who stay Sam’s members. A flat 2 percent cash card pays uncapped rewards monthly with no membership or ecosystem lock, which suits most people better.
