Yes — 23 days. And by the account agreement's own wording, it does not apply to the promotional purchase you probably opened the card for.
The CareCredit Credit Card Account Agreement issued by Synchrony Bank states that your due date is at least 23 days after the close of each billing cycle, and that no interest is charged on non-promotional purchases if you pay your entire balance by the due date each month. That is a normal credit card grace period, and it works the way you would expect.
Two sentences later, the same agreement says something most people never read:
So the grace period is real, and it covers ordinary purchases. Your $4,000 dental promotion is not an ordinary purchase. Interest on that balance started accruing the day the dentist ran the card, has been accruing every day since, and is sitting in a reserve that gets released in full if any part of the promotional balance is still there when the promo ends. There is no 23-day window on that. There is no window on that at all.
This is the single most misunderstood thing about the card, and it is why people who paid on time every month still get hit. On-time payments protect you from late fees. They do not, by themselves, protect you from deferred interest.
The late fee is tiered, which is a detail almost every summary of this card gets wrong by quoting a single flat number:
Two things worth knowing about that table. First, the late fee is treated as a new purchase under the agreement's own balance math, so it starts accruing interest itself. Second, the paper statement fee is avoidable — switch to electronic statements and it stops.
There is no stated grace window on the due date itself. Cardholders on credit forums routinely report a fee posting for a payment made hours after the deadline. Whether a first-time fee gets reversed on request is a separate question, and the answer is often yes — see the section below.
The standard purchase APR on this card is 32.99% (a daily rate of .09039%). That is already high. The penalty APR is 39.99% (daily rate .10957%), and the agreement is specific about how you trigger it and how long it lasts:
Read that trigger carefully, because it is more forgiving than people fear and more dangerous than people realize. One late payment does not trigger the penalty rate. Two inside a rolling twelve-month window does — and they do not need to be consecutive. A missed minimum in January and another in October are enough.
This is the question underneath most searches that land here. The honest answer has three parts, and only one of them is alarming.
It does not cancel the promotion. A single late payment does not, by itself, void a deferred interest promotion or immediately release the reserve. The promotion still ends on its stated expiration date, and the reserve still fires only if a promotional balance remains on that date.
It does cost you a fee and it may cost you the grace period on everything else. Once you carry a balance into a new cycle without paying in full, ordinary purchases stop being covered by the 23-day window until you pay in full again for a full cycle.
It puts you one miss away from 39.99%. That is the real damage. A second missed minimum inside twelve months moves the whole account to the penalty rate, potentially permanently, and the balance you are trying to clear before the deadline just got substantially more expensive to carry.
Under 30 days late is generally not reported to the credit bureaus. Card issuers typically report a delinquency at the 30-day mark, not the day after a due date. Being four days late is a fee problem, not a credit-report problem. Being 30+ days late is both.
If this is your first late payment in a long stretch of on-time ones, call the number on the back of the card and ask for a courtesy adjustment. Keep it short and factual:
“I've had this account since [year] and this is my first late payment. It was [reason — autopay lapsed, payment posted a day late]. The balance is paid now. I'm asking for a one-time courtesy reversal of the late fee.”
A clean payment history is the leverage. Issuers grant these routinely for accounts in good standing because the alternative is losing a performing customer over $30. If the first representative declines, politely ask to escalate. If the fee has already pushed you toward a second miss, say so — the penalty APR is the thing worth fighting to avoid, not the fee.
Plenty of people arrive at this page looking for the grace period because they are hoping it buys them time on a promotional balance. It does not. If the promotion is the actual problem, the fee is a rounding error next to what is coming.
The exact release figure depends on your balance, your promo length, and how fast you paid it down — the CareCredit calculator computes it from your own numbers rather than a generic example.
Paying the promotional balance in full — including with a true 0% intro APR balance transfer — satisfies the promotion and waives the reserve permanently.
