Credit card companies charge two different kinds of interest after you miss a payment

When you pay late, your card issuer does not charge you extra interest on top of what you already owe. Instead, they do two things: they stop giving you the low interest rate you had before, and they may charge you a penalty APR — a much higher interest rate that applies to your balance going forward.

The difference between these two is important. Your regular APR is what you pay interest on every day you carry a balance. Your penalty APR is what you pay if you miss a payment by 60 days or more. The penalty APR is almost always much higher — often 10 to 15 percentage points above your regular rate, though the exact amount depends on your card and your agreement with the issuer.

You also get charged a late fee — a flat dollar amount, usually $25 to $40 for a first late payment, higher for repeat lates. This fee is separate from interest and is charged once per missed payment cycle.

Key Takeaways

  • A penalty APR is a higher interest rate that kicks in after you miss a payment by 60 days or more, and it applies to your entire balance, not just the late amount.
  • Your regular APR stops explore once you hit 60 days late; the penalty APR can be 10 to 15 percentage points higher and stays in place for at least six months.
  • Late fees are charged separately from interest and typically range from $25 to $40 for a first late payment.
  • Paying at least the minimum before you reach 60 days late can prevent the penalty APR from being triggered, though you will still owe a late fee.

When the penalty APR actually takes effect

The penalty APR does not kick in the moment you miss a payment. Credit card companies are required by federal law to give you a grace period. If you are 30 days late, you get charged a late fee, but your regular APR still applies. At 60 days late, the penalty APR takes over.

This means if you are 30 to 59 days late, you are paying your regular interest rate plus a late fee. Once you hit 60 days, the interest rate itself jumps. The issuer will send you a notice before this happens — usually around day 45 or 50 — telling you the new rate and when it takes effect.

The penalty APR stays in place for a minimum of six months, even if you catch up on payments. After six months of on-time payments, the issuer may lower your rate back to the regular APR, but they are not required to do so. Some issuers keep the penalty rate indefinitely until you pay off the balance or close the account.

How the interest actually gets calculated on your balance

Interest on a credit card is calculated daily. Your issuer takes your balance at the end of each day, multiplies it by your APR, divides by 365, and adds that to what you owe. This happens every single day, so interest compounds — you pay interest on the interest you already owed.

If your regular APR is 18% and your penalty APR is 29%, the difference in what you pay each day is significant. On a $2,000 balance, the regular rate costs you about $0.99 per day in interest. The penalty rate costs you about $1.59 per day. Over a month, that is roughly $18 extra in interest charges just from the rate increase, before you even count the late fee.

The longer you stay late, the more this compounds. If you are 60 days late on a $2,000 balance and it takes you another 30 days to pay it off, you will have paid roughly $50 to $60 in extra interest just from the penalty APR, plus the late fees. The exact amount depends on your specific APR and how quickly you bring the account current.

What happens if you pay the minimum before 60 days

If you are 30 to 59 days late and you make a payment that brings your account current — meaning you pay everything you owe, including the late fee — the penalty APR does not trigger. You will have paid the late fee, and your interest will have been calculated at the regular rate for those days you were late, but you avoid the jump to the penalty rate.

This is why paying as soon as you realize you are late matters. If you can scrape together the full amount owed before day 60, you stop the penalty APR from ever taking effect. If you can only pay part of what you owe, you are still late, and the clock keeps running toward day 60.

Paying the minimum payment is not the same as bringing your account current. If you owe $500 and your minimum is $25, paying $25 does not stop the late clock. You have to pay the full $500 plus the late fee to be current again.

The difference between penalty APR and regular APR increases

Some credit card issuers also have the right to increase your regular APR if you are late, even without triggering the penalty APR. This is called a rate increase or repricing, and it is different from a penalty APR.

A rate increase can happen at any time — even if you are only 30 days late — and it applies to new purchases and future balances. A penalty APR applies to your existing balance. Both can happen to the same account. You might see your regular rate go up from 18% to 22%, and then your penalty APR kick in at 29% if you hit 60 days late.

Your card agreement spells out when the issuer can do this. Most agreements say they can increase your rate if you are 60 days late, but some allow it at 30 days. Read your agreement or call the number on the back of your card to find out what your issuer's policy is.

How to stop the interest from climbing once you are late

The fastest way to stop additional interest charges is to pay your full balance, including the late fee. Once you do, your account is current again, and the interest clock resets. You will not owe any more late fees for that cycle, and if you have not hit 60 days yet, the penalty APR will not trigger.

If you cannot pay the full amount, call your card issuer and ask about a hardship program. Many issuers have programs for people facing temporary financial difficulty. These programs can lower your interest rate, waive late fees, or set up a payment plan. You have to ask — the issuer will not offer this on their own. Be honest about your situation and ask what options are available.

If you are already at the penalty APR and cannot pay the full balance, paying on time going forward will eventually get you back to the regular rate after six months. In the meantime, every payment you make reduces the balance the penalty APR is being applied to, which reduces the total interest you pay.

What to do if the late fee or interest seems wrong

Credit card issuers make mistakes. If you see a late fee you do not think you owe, or an interest charge that does not match what you expected, you have the right to dispute it. Call the number on the back of your card and ask to speak with someone in the billing department. Have your statement in front of you and explain what you think is wrong.

If the issuer made an error — for example, they posted your payment late or applied it to the wrong account — they should reverse the fee and recalculate the interest. If you have a legitimate reason for the late payment (a mail delay, a bank error, a death in the family), some issuers will waive the fee as a one-time courtesy, especially if you have a good payment history otherwise.

If the issuer will not fix it and you believe they violated federal law, you can file a complaint with the Consumer Financial Protection Bureau (CFPB) at consumerfinance.gov. The CFPB investigates complaints about credit card companies and can force them to refund fees or interest if they find a violation.

Frequently Asked Questions

Can I negotiate the penalty APR down if I call the card company?

Some issuers will lower the penalty APR if you call and ask, especially if you have a long history of on-time payments and this is your first late. There is no harm in calling and asking. Be polite and explain your situation. The worst they can say is no.

Does the penalty APR explore to new purchases I make after I am late?

Yes. Once the penalty APR is in effect, it applies to your entire balance and to any new purchases you make. This is another reason to avoid carrying a balance on a card where you have been late — the interest rate on everything gets much higher.

If I pay off the balance, does the penalty APR go away when ready?

Yes. Once your balance is zero, there is nothing for the interest rate to explore to. If you later carry a balance again on the same card, the penalty APR will not explore unless you are late again. However, the issuer may keep your regular APR higher than it was before.

What if I am only one or two days late — do I still get charged interest?

You will be charged a late fee if you are even one day past the due date. Interest charges depend on your card's terms — some charge interest starting on day one of lateness, others only after 30 days. Check your card agreement or call to find out your issuer's specific policy.

Does paying late hurt my credit score even if I pay the late fee?

Yes. Paying the late fee stops additional interest and fees from piling up, but the late payment itself is already reported to the credit bureaus. Your credit score will be affected whether you pay the fee or not. The fee only stops future charges — it does not erase the late payment from your history.
