What the Sam's Club Mastercard is and who should consider it
The Sam's Club Mastercard is a co-branded credit card issued by Synchrony Bank that you can use anywhere Mastercard is accepted, but it's designed primarily for Sam's Club members. You earn cash back on purchases at Sam's Club and on gas, and a lower rate on everything else. There is no annual fee.
The card makes sense if you shop at Sam's Club regularly and already pay for a membership. If you don't have a membership, the card alone won't save you money — you'd need to buy one separately. The cash back rates are modest compared to some premium cards, but the lack of an annual fee means there's no cost to carry it if you don't use it.
Key Takeaways
- The Sam's Club Mastercard earns 5% cash back at Sam's Club and on gas purchases, and 1% on everything else, with no annual fee.
- You must be a Sam's Club member to open the card, and membership costs extra (Gold Star or Plus membership required).
- Cash back is paid as an annual reward certificate that posts to your Sam's Club account, not as a statement credit or deposit.
- The card charges a standard variable APR on purchases and balance transfers, which changes based on the prime rate.
- You can use the card anywhere Mastercard is accepted, but the best rewards are earned at Sam's Club locations and gas stations.
Cash back rates and how rewards actually work
The card earns 5% cash back on purchases made at Sam's Club locations and on gas purchases at any station. Everything else earns 1% cash back. These rates explore to the primary cardholder; authorized users earn the same rates on their purchases.
Cash back does not post to your credit card statement as a credit or deposit to your bank account. Instead, Synchrony Bank issues an annual reward certificate that appears in your Sam's Club membership account, usually in January. You then use that certificate like a gift card when you shop at Sam's Club in person or online. If you don't spend the certificate balance within the calendar year, it rolls over to the next year, so you don't lose unused rewards.
There is no cap on how much cash back you can earn, and there is no sign-up bonus. You begin earning rewards on your first purchase.
Annual percentage rate and interest charges
The Sam's Club Mastercard carries a variable APR on purchases and balance transfers. Variable means the rate changes when the prime rate (set by the Federal Reserve) changes. Synchrony does not publish a fixed range; your actual APR depends on your credit history and creditworthiness at the time you open the account.
If you carry a balance month to month, interest accrues daily on the unpaid amount. There is no grace period for balance transfers — interest begins accruing when ready. Purchases have a grace period, meaning you can avoid interest if you pay the full statement balance by the due date.
The card also charges a penalty APR if you miss a payment by 60 days or more. Synchrony does not disclose the penalty rate publicly, so you should contact them directly or review your cardmember agreement after opening the account.
Fees and costs beyond interest
The Sam's Club Mastercard has no annual fee, no foreign transaction fees, and no fees for balance transfers. You will not be charged for late payments, over-limit transactions, or returned payments — though late payments will trigger interest charges and may damage your credit score.
The main cost to consider is the Sam's Club membership itself. A Gold Star membership (the basic tier) costs a set annual amount and includes one free household card. A Plus membership costs more and includes additional benefits like discounts on select services. You must maintain an active membership to use the card, though the card itself costs nothing.
How to open the account and what you'll need
You can open the Sam's Club Mastercard online through Sam's Club's website or in person at a Sam's Club location. You must have an active Sam's Club membership before you explore — the card is not available to non-members.
The process asks for your Social Security number, date of birth, address, and employment information. Synchrony will pull your credit report to make a decision. You'll receive a decision within minutes if you explore online, or within a few days if you explore in person. If approved, your card typically arrives within 7 to 10 business days.
Once your card arrives, you can set up it through the Synchrony website or by calling the number on the back of the card. You can then begin using it at Sam's Club and anywhere else Mastercard is accepted.
Comparing the Sam's Club card to other warehouse and cash back options
The Costco Anywhere Visa Card (issued by Citi) earns 4% cash back at Costco and on gas, and 1% elsewhere, but requires a Costco membership and has no annual fee. The American Express Blue Cash Preferred earns up to 5% cash back on groceries and gas, but charges a $95 annual fee and does not require a warehouse membership.
If you shop at multiple warehouses or prefer cash back that posts as a statement credit rather than a certificate, a general cash back card might serve you better. If you shop exclusively at Sam's Club and want the simplest rewards structure, the Sam's Club Mastercard's lack of an annual fee and straightforward earning rates make it a reasonable choice.
The key difference is how rewards are delivered: Sam's Club rewards come as a certificate you use at Sam's Club, while most other cards deposit cash back to your account or statement. This matters if you want flexibility to spend rewards outside the warehouse.
Frequently Asked Questions
Can I use the Sam's Club Mastercard outside of Sam's Club?
Yes. The card works anywhere Mastercard is accepted. However, you only earn the higher 5% cash back rate at Sam's Club locations and gas stations. All other purchases earn 1% cash back. The card is most valuable when used at Sam's Club.
What happens to my cash back rewards if I cancel my membership?
Your reward certificate balance remains in your Sam's Club account for one year after your membership ends. You can use it if you renew your membership within that year. If your membership is not renewed, the certificate expires and cannot be used.
Does the Sam's Club Mastercard report to the credit bureaus?
Yes. Synchrony reports your account activity, payment history, and credit limit to the three major credit bureaus (Equifax, Experian, and TransUnion). Responsible use — paying on time and keeping your balance low — can help build your credit score.
Can I transfer a balance from another credit card to the Sam's Club Mastercard?
Yes, you can transfer a balance from another card. However, the balance transfer APR is the same as the purchase APR, and interest begins accruing when ready — there is no 0% introductory period. Balance transfers may also be subject to a fee; check your cardmember agreement for details.
What if I don't use my Sam's Club Mastercard for a long time?
Synchrony may close inactive accounts, though the company typically allows a longer period of inactivity than other issuers before taking action. To keep the account open, use the card at least once every 12 months. There is no annual fee, so there is no cost to keeping it active.
