TL;DR

Two cards share the Sam’s Club brand:

1. Sam’s Club Mastercard (this page): open-loop Synchrony Mastercard, 20.40-28.40% APR, no deferred interest, behaves like a normal rewards Mastercard.
2. Sam’s Club Consumer Credit Card (separate page on this site): closed-loop store-only Synchrony card with deferred-interest promotional financing on big-ticket items, in the 28-31% APR range. See the store credit card payoff calculator for that product’s framework.

The card name on the front and the network logo on the back are how you distinguish them. The 5% gas reward is on the Mastercard version only.

Math worked example

$2,000 balance at 24.40% APR (midpoint), $80/mo payment:

• 32 months to payoff
• $605 interest paid
• Total cost: $2,605

Same balance, $160/mo payment:

• 15 months to payoff
• $279 interest paid
• Total cost: $2,279

Doubling the payment cuts interest by 54% and shortens payoff by 17 months. The marginal $80 a month buys you roughly $326 of interest savings.

The rewards math: 5% on $200/mo of gas spending = $10/mo. Interest on $2,000 at 24.40% = roughly $41/mo. Rewards offset 24% of interest in the best-case category, meaning carrying any balance is net negative.

Mastercard vs closed-loop Sam’s Club card

If you see a 28%+ APR on your Sam’s Club card and no Mastercard logo on the back, you have the closed-loop store card. That product:

• Is accepted at Sam’s Club locations and Sam’s Club gas pumps only
• Offers deferred-interest financing on appliances, tires, and HVAC
• Has materially worse carry-balance math than the Mastercard

Per the CFPB deferred-interest guide, the closed-loop product retroactively charges interest from the purchase date if the full balance is not paid by the promo deadline.

How the variable APR moves

Synchrony Mastercard APRs are quoted as “Prime + X.XX%”. With the prime rate at about 8.5% per the Federal Reserve H.15 release, a 24.40% APR implies prime plus roughly 15.9 percentage points. A one-point hike in prime raises your APR by one point and adds about $20 of annual interest per $1,000 of carried balance.

Rewards-vs-interest break-even

The 5% gas reward is the headline benefit, but it covers only a slice of total spending. Even at the $6,000 annual gas cap (the maximum 5% category), you earn $300 a year in cashback. Carrying a $2,000 balance for a full year at 24.40% APR costs roughly $488 in interest. The reward does not catch up.

The honest math: this card pays you when you transact and pay in full. It costs you when you revolve.

Annual cashback payout timing

A subtle gotcha: Synchrony pays Sam’s Club Mastercard cashback as a once-a-year lump sum each February, not monthly. If you cancel the card or your membership before February, accrued cashback can be forfeited per the cardholder agreement. The card is built around the assumption of an active multi-year relationship.

For someone working through debt payoff, this means deferred reward gratification while the interest meter is running. The math nearly always favors transferring the balance to a 0% APR card rather than waiting on rewards.

Balance transfer option

Sam’s Club Mastercard balances can be transferred to a 0% APR card from another issuer. On a $2,000 balance at 24.40%:

• Status quo, $80/mo: 32 months, $605 interest, $2,605 total
• Transfer to 18-month 0% APR with 3% fee ($60 fee): if paid in 18 months at $114/mo, total cost $2,060. Savings: $545.

The balance transfer calculator handles the precise math on your numbers.

When to keep the card after payoff

If you spend $2,000+ a year on gas, the 5% reward (worth $100) plus $100-$200 of Sam’s Club category rewards can offset the implicit cost of the $50-$110 membership. In that case, keeping the card open at zero balance is rational.

If your gas spending is low or you do not regularly shop at Sam’s Club, closing the card after payoff is fine. The credit limit on the Mastercard is typically larger than on closed-loop store cards, so the utilization impact is more pronounced; review your total available credit picture first.

Frequently asked questions

What is the APR on the Sam’s Club Mastercard?

20.40-28.40% variable as of May 13, 2026, per the Sam’s Club credit landing page. Your specific APR was assigned at application by Synchrony Bank based on your credit profile. The penalty APR can rise to 29.99% after 60 days late per the cardmember agreement.

Does the Sam’s Club Mastercard use deferred interest financing?

No. The open-loop Mastercard product does NOT use deferred interest on standard purchases. The separate Sam’s Club Consumer Credit Card (closed-loop, Sam’s Club only) DOES use deferred-interest promotional financing on big-ticket items, per the CFPB deferred-interest guide. Check the back of your card for the Mastercard logo to confirm which product you hold.

How is the 5 percent gas cashback paid?

Synchrony pays Sam’s Club Mastercard cashback once a year as a lump sum each February, either as a check or as a Sam’s Club gift card. The 5% rate is capped at $6,000 of gas spending per calendar year. Beyond that cap, gas spending earns 1%. Cashback is forfeited if the card or Sam’s Club membership is canceled before the annual payout.

Can I do a balance transfer onto the Sam’s Club Mastercard?

The Sam’s Club Mastercard does not advertise a 0% intro APR balance transfer promotion as of May 2026. If you transfer a balance in, it accrues at the standard 20.40-28.40% APR plus a transfer fee, which provides no savings. For balance transfer savings, transfer your Sam’s Club Mastercard balance OUT to a dedicated 0% APR transfer card from another issuer.

What is the minimum payment formula?

Per the Sam’s Club Mastercard cardholder agreement, the minimum is 1% of the balance plus interest and fees with a $29 floor. On a $2,000 balance accruing roughly $41 in monthly interest, the minimum is approximately $61. Paying only the minimum extends payoff well past 10 years and roughly doubles the principal in total interest paid.
