The Amazon Store Card's interest rate

The Amazon Store Card’s purchase APR is 29.74% variable (Synchrony — Amazon Store Card account agreement, verified 2026-11-09). This page previously carried that figure with a secondary-source flag, because Synchrony’s site did not respond to us. On our October 2026 re-check we reached Synchrony’s own account agreement for the card, so the rate is now read from the issuer. The revision it serves today states 29.74% on purchases — the prime rate plus 22.74% — varying with the Prime Rate and still capped at 29.99%.

That is a better citation, and it still is not the last word. Before you accept an offer, read the rate in the terms Synchrony shows you on your own application. A published agreement states the rate a card carries; your application states the rate your account carries, and that is the version that governs it.

“Variable” means the rate tracks a published index and moves when that index moves. It is not fixed for the life of the account.

The reported store card rate sits above the top of the Visa’s entire range. Even a Prime Visa holder who was offered the worst end of Chase’s range would be paying less to carry a balance than a store card holder at the reported rate.

That is not unusual and it is not a scandal — store cards routinely price higher than general-purpose cards, because they are underwritten for a more accessible credit tier and the risk is priced in. It does mean that if there is any chance you will carry a balance, the store card is the more expensive of the two Amazon options by a clear margin, and the head-to-head comparison should be read with that weighted in.

The card’s appeal is 5% back at Amazon.com and Whole Foods Market for cardholders with an eligible Prime membership (Yahoo Finance — Amazon Store Card review, secondary source, verified 2026-08-11). Here is what happens when that rate meets the interest rate on the same account.

The store card has a specific aggravating factor here, and it is the credit line. Starting limits are small, which means a carried balance is often a large percentage of the account. That does two things at once: it is expensive, and it reports badly. The people most likely to carry a balance on this card are the people most likely to be trying to rebuild credit with it, which is a genuinely unfortunate combination.

Everything above is about revolving a balance. The card has a second mode where the APR does not apply, and it is worth being clear about the difference.

a 0% APR plan that divides an eligible purchase into equal monthly installments with no retroactive interest, offered on qualifying purchases based on item eligibility and cart total rather than a published price band (Amazon — Store Card promotional financing, verified 2026-10-11). That is a real 0% structure: a fixed number of installments, a defined end date, no interest if you follow the schedule. Used deliberately on a purchase you can afford to repay on that schedule, it is a reasonable tool and the APR on this page is irrelevant to it.

It is also the safe successor to something that was not safe. Synchrony stopped offering deferred-interest promotional financing on new Amazon Store Card purchases; Equal Monthly Payments remains (Amazon — Store Card promotional financing, verified 2026-10-11), effective the week of February 16, 2026 (Amazon — Store Card promotional financing, verified 2026-10-11). Deferred interest accrued quietly during the promotional window and was charged retroactively in full on the original purchase amount if any balance survived to the end of it. At a rate near 29.74%, that was a genuinely punishing trapdoor, and its removal is the best thing that has happened to this card. The whole story is on the financing change page.

One caution that still applies: a financing plan is a commitment, not a discount. If you miss the schedule, you are back on the ordinary balance and the ordinary rate.
