A penalty APR is a higher interest rate a credit card issuer can charge when you violate one of the account's terms. Most often that violation is a late payment or a returned payment, and the difference between your everyday rate and the penalty rate can be stark. While a penalty APR does not show up on every card, the terms sheet for any card that carries one must include a row titled "Penalty APR and When it Applies." That row tells you exactly which events trigger the higher rate and how long it lasts, so you know the cost before you miss a due date.
Federal rules limit when and how an issuer can apply a penalty rate. Those limits protect your existing balance until you cross a specific threshold of lateness and give you a path back to your regular rate if you follow the rules. Here is how penalty APR works, what the law requires, and the steps you can take to return to your old rate.
What a penalty APR is
A penalty APR is a fixed higher rate, not a rate that adjusts when your credit score changes. When a card has one, it is typically disclosed at application and set in the account agreement. Commonly cited penalty rates run as high as 29.99 percent, so the spread over a regular purchase rate can be substantial. Not every card has a penalty APR, which makes this disclosure one more detail to compare when you read a card's terms.
A penalty APR is generally applied to future purchases while it is in effect. Whether the higher rate also reaches your existing balance depends on the issuer's terms and how late your payment becomes. Federal law limits when a penalty can touch money you already owe, and understanding that limit helps you predict what a single missed payment will cost.
Limits on rate increases and the two routes a penalty can take
Issuers generally cannot raise the rate on new transactions during the first year of an account. After the first year, a rate increase for new purchases generally requires at least 45 days' advance notice. Purchases made before the notice takes effect, or within 14 days after the notice is sent, cannot be charged the higher penalty rate. This window gives you time to understand the change before it touches new spending.
The penalty can reach your existing balance only once a minimum payment is more than 60 days late. This is the 60-day rule. A single late payment usually affects only new purchases. A longer delinquency can extend the higher rate to money you already owe. These two routes mean that the same penalty APR can apply in different ways, depending on how long you have been behind.
Temporary rates, such as a promotional balance-transfer rate that expires, and variable rates that move with their index are permitted exceptions to the existing-balance protection. Knowing these exceptions helps explain why your rate might change even when no penalty has been triggered. The governing rules are in Regulation Z, specifically 12 CFR 1026.55, 1026.59, and 1026.60, which the Consumer Financial Protection Bureau publishes in full. Those regulations describe when a rate increase is allowed, when it must be reviewed, and what the issuer must disclose.
What can trigger a penalty and how long it lasts
Common triggers include late payments, failing to make the minimum payment, payments returned because of a closed account or insufficient funds, and, depending on the issuer, going over your credit limit. Paying less than the minimum can also count as a late payment. A triggered penalty can also end any active introductory APR you were receiving, so a single missed payment can affect more than one rate on your account.
A penalty rate may end when the issuer reviews the account after six months of on-time payments. If violations continue, the higher rate can stay in place longer. The cost of a penalty rate can be significant. Interest compounds, so if you pay only the minimum on a balance carrying a high rate, the debt can take much longer to clear and cost considerably more. An April 2025 article noted that average credit card rates were hovering close to 22 percent, with the average balance closing in on $8,000. A jump to a 29.99 percent penalty rate on that balance would add hundreds of dollars in interest over time if only minimum payments are made.
How to check your card's penalty terms
The Schumer box in your card agreement shows the APRs and includes the "Penalty APR and When it Applies" row. Read it to learn which events trigger the higher rate and how long it lasts before you apply for a card or when you receive new terms. Compare whether a card discloses a penalty APR at all. Because not every card has one, this detail can matter as much as the advertised rate when you evaluate the agreement.
Useful questions to ask the issuer include which events trigger the penalty, whether it applies only to new purchases or also to the existing balance, and what you must do to have your old rate restored. The sources available do not describe a specific script or method for making that request, so calling the customer service number on the back of your card and asking directly is the clearest route to an answer.
How to get back to your regular rate
The first step is to bring your account current and keep it that way. Make at least the minimum payment on time every month. Automatic payments or calendar reminders can help, and paying the full statement balance on time can avoid interest on new purchases. Consistency matters more than the size of the payment when you want to demonstrate that you are following the terms again.
Federal rules describe a route back for the existing balance. If a penalty increase has taken effect on your existing balance after a 60-day delinquency, six consecutive on-time minimum payments can return the old rate on that balance. This rule gives you a clear benchmark and a timeline. After six payments, the issuer restores your original rate on the money you already owed.
After a penalty increase that required 45 days' notice, the issuer must review the account at least every six months and lower the rate when appropriate. You can ask the issuer to review your account, though the sources available do not describe a specific script or method for making that request. If you have an arrangement with the issuer to lower the rate, completing or complying with its terms is one listed route back to your regular rate.
If you believe a penalty was applied incorrectly or the issuer did not follow these rules, the Consumer Financial Protection Bureau publishes consumer guidance on credit card interest rate increases and can explain your options. For how a penalty APR may affect your credit report or credit scores, consult the credit bureaus' consumer pages and the CFPB rather than assuming a result. A penalty APR is not the same as a delinquency notation, and the two can have different effects on your credit history.
