People hear "account anniversary" and assume something happens on that date. Maybe the rate changes. Maybe a fee lands. The CFPB guidance I reviewed is narrower than that. It talks about the first year of an account and what comes after, and it never ties either one to an anniversary. That gap matters, so this piece sticks to what the guidance actually says.
A general protection is not the same as an absolute one.
What the first-year rule covers
Under the CFPB's plain-language guidance, a card issuer generally cannot raise the interest rate on new purchases during the first year of a credit card account. That is the rule most people connect to a card's early months.
Notice what the guidance does not say. It states the one-year rule, but it does not explain how to count that year, and it does not call the account anniversary the marker. So a cardholder should not assume protection flips off on a particular calendar day. If the exact date matters to you, the account agreement and the issuer are the places to confirm it.
Notice requirements after the first year
After the first year, the issuer generally must give 45 days' advance notice before raising the rate on new purchases. Think of it as a window to read the change and decide what to do.
Here is a scenario. A notice arrives on a Monday. Purchases made more than 14 days after that notice are treated as new transactions, so they can carry the higher rate. Purchases made before that point are handled differently under the guidance. A grocery run on day 5 and a flight booked on day 20 may not be treated alike. Checking dates on your statement against the notice date is worth the few minutes it takes.
Why existing balances are treated differently
Existing balances are generally protected from rate increases. The word "generally" is doing real work, because the CFPB lists exceptions:
- A temporary promotional rate, such as a low balance-transfer rate, that has expired. It can revert to a higher rate only if it lasted at least 6 months.
- A variable rate that rises with its index, for example the U.S. Prime Rate.
- A minimum payment not received within 60 days after its due date.
- Failing to meet the terms of an arrangement that lowered the rate.
These are different kinds of triggers. Some are about the calendar, like a promo ending. Some are about the market, like an index moving. One is about your own payment behavior. Protections under the Servicemembers Civil Relief Act may also apply depending on a cardholder's situation, though the sources do not explain how that works in practice.
Questions to answer from your own account records
Most of this can be checked against paperwork you already have. Start with the notices. Has the issuer sent a 45-day notice before any change on new purchases? Then look at the rate itself. Is it temporary, and when does it end? Is it variable and tied to an index?
Payment history belongs on the list too. Was any minimum payment received more than 60 days after its due date? That is one of the listed triggers for a rate change on an existing balance. Working through these questions is an educational exercise. It does not replace reading your agreement or asking the issuer directly.
What the available sources do not answer
Several things people expect an anniversary to explain are simply not covered here. The sources reviewed do not describe when annual fees are billed, or whether they can be refunded or prorated. For that, check the card agreement and the CFPB's current guidance on fees, including its page on limits on fees.
They also do not say how to request a lower rate, what a hardship arrangement looks like, or how a rate change affects credit scores. The exact regulatory text on rate-increase limits, found in section 1026.55, was not available in the material reviewed, so this article does not quote it. The plain-language starting point is the CFPB's page on when a card company can increase your interest rate.
