Credit card mistakes, and what each one costs
The most expensive credit card mistake is paying only the minimum. On $4,350, the New York Fed’s average credit card balance per person with a credit report at the end of 2025, at the Federal Reserve’s average 22.36% APR on accounts charged interest (August 2026), Capital One’s published minimum-payment rule takes 18 years and 1 month and $7,030 in interest to clear the balance. Paying $190 a month instead clears it in 2 years and 7 months for $1,374. Below, each mistake is priced the same way, from issuers’ own terms for the 141 US cards in our records and from official data.
What common credit card mistakes cost
Each figure is calculated from published terms or official data, on the stated example. Your own costs depend on your card, your balance and how long the mistake lasts.
| Mistake | What it costs | Calculated from |
|---|---|---|
| Paying only the minimum | $7,030 in interest over 18 years and 1 month | Capital One’s minimum-payment rule on $4,350 at 22.36% |
| Carrying a balance on a rewards card | $973 a year in interest | Against $357 a year from the median card’s rewards |
| Paying late | $39–$41 a time, and up to $848 more interest a year | Late fees on 33 cards; penalty APRs up to 39.99% on 17 |
| A balance transfer paid too slowly | $468 instead of $148 | The cheapest of 61 offers, at $124.56 against $190 a month |
| A fee card your spending doesn’t pay for | 15 of 15 fee cards | Worth less than the best no-fee card for the BLS middle-income household |
| A cash advance | $36.91 on $500 for 30 days | Median fee and cash APR across 106 cards |
| Foreign transaction fees | $60 on $2,000 spent abroad | 43 of 128 cards charge 3%; 82 charge nothing |
What does paying only the minimum cost?
Paying only the minimum on $4,350, the New York Fed’s average credit card balance per person with a credit report at the end of 2025, at the Federal Reserve’s average 22.36% APR on accounts charged interest (August 2026) takes 18 years and 1 month and costs $7,030 in interest, more than the balance itself. That is under Capital One’s rule, which its pricing pages state in these words: “your minimum payment will be the greater of $25 or 1% of your balance plus new interest and late payment fees”. The first minimum is $124.56, and it shrinks as the balance does, so most of each payment goes on interest for years.
A fixed $190 a month, enough to clear the balance in two years if no interest were charged, clears it in 2 years and 7 months for $1,374 in interest: $5,656 less. The CFPB found that about 15% of general purpose cardholders made only the minimum payment in 2024.
| How you pay | Paid off in | Interest paid |
|---|---|---|
| The minimum each month (starts at $124.56) | 18 years and 1 month | $7,030 |
| $190 every month | 2 years and 7 months | $1,374 |
Interest is worked out monthly at the APR divided by 12; issuers charge daily, so statements differ slightly. Other issuers set their own minimum: check the “minimum payment” wording in your card’s terms.
What does one late credit card payment cost?
One late payment costs a late fee of up to $39–$41 on the 33 cards whose pricing terms we saved, and it can do more damage than the fee. The CFPB warns that a missed minimum payment can raise your rate to the penalty APR for new purchases and end an introductory rate on your existing balance. (Source: CFPB) A late payment can also stay on your credit report for up to seven years. (Source: CFPB)
| Issuer | Late fee | Cards |
|---|---|---|
| American Express “Late Payment Up to $40.” | Up to $40 | 7 |
| Capital One “Late Payment Penalty Fee: Up to $40” | Up to $40 | 11 |
| Discover “Late Payment Penalty Fee: None the first time you pay late. After that, up to $41” | None the first time, then up to $41 | 4 |
| Fifth Third “Late Payment Fee of up to $41.” | Up to $41 | 4 |
| Regions “Late payment fee of up to $39.” | Up to $39 | 3 |
| Wells Fargo “Late Payment Up to $40” | Up to $40 | 4 |
How much more interest does a penalty APR add?
A penalty APR replaces your card’s own rate, so its cost depends on where you started. On $4,350 for a year, it adds between nothing and $848, depending on the issuer and on where your own APR sits in the card’s range. Penalty rates and the triggers for them differ widely: credit unions in our records apply theirs only after 60 days, while others apply theirs after a single late payment.
| Issuer | Penalty APR, up to | Triggered by | Extra interest a year on $4,350 |
|---|---|---|---|
| Citi 6 cards. “Penalty APR up to 29.99 % and applies if you pay late or your payment is returned” | 29.99% | A late or returned payment | $54 to $576 |
| Synchrony 1 card. “Penalty APR 30.49%, 37.49% or 39.99%” | 39.99% | A late payment, as its terms set out | $294 to $848 |
| Verizon (issued by Synchrony) 1 card. “Penalty APRs are 32.24%, 37.24% or 39.99%” | 39.99% | A late payment, as its terms set out | $294 to $772 |
| Navy Federal 6 cards. “Penalty APR is 18% and may apply to an account that is over 60 days past due” | 18% | Being more than 60 days past due | $0 to $338 |
| PenFed 3 cards. “Penalty APR and When 17.99% … If your minimum payment is not received within 60 days, your entire account is subject to change to the non-variable Penalty APR” | 17.99% | A minimum payment not received within 60 days | None: no higher than its cards’ own rates |
The pricing pages of the 15 Capital One and Discover cards we saved list their penalty fees and no penalty APR. Across the industry, the CFPB counted $17 billion in late fees charged in 2024, and the Atlanta Fed found that 8% of credit card holders paid a late fee in 2025.
Late fees and penalty APRs cover 33 and 17 of our 141 US cards: the cards whose saved pages include the issuer’s pricing table. For other cards, check the “Penalty Fees” and “Penalty APR” rows of the card’s own rate table.
Why is carrying a balance on a rewards card a mistake?
Because the interest is usually far more than the rewards. A year’s interest on $4,350, the New York Fed’s average credit card balance per person with a credit report at the end of 2025, at the Federal Reserve’s average 22.36% APR on accounts charged interest (August 2026) comes to about $973. On the spending of the BLS middle-income household, the median card in our records is worth $357 a year after fees, and the best is worth $498. Both are smaller than the interest. If you carry a balance, a lower APR or a balance transfer is worth more than any rewards rate: see what a balance transfer would cost on each card.
When does a balance transfer go wrong?
A balance transfer goes wrong when the payment is too small to clear the balance before the intro rate ends. On $4,350, paying $124.56 a month, the first minimum under Capital One’s rule, the cheapest of the 61 transfer offers in our records costs $468 in fees and interest over 3 years and 3 months. Paying $190 a month, the cheapest costs $148. Both still beat staying put, which costs $2,747 and $1,374 at those payments.
The other common slip is assuming a 0% transfer offer covers new purchases. 61 cards in our records have an intro rate on balance transfers; 39 have one on purchases. The transfer fee is usually charged up front: the median in our records is 3.5% and the highest 5%. A late payment can also end the intro rate early. (Source: CFPB)
When is an annual fee a mistake?
An annual fee is a mistake when your spending doesn’t earn it back. On the spending of the BLS middle-income household, 15 of the 15 cards with an annual fee that we can value are worth less, on rewards alone, than the best card with no annual fee. For 14 of them, no amount of spending in that household’s mix closes the gap. These cards can still pay for themselves through perks we don’t value, such as statement credits or lounge access, so check those against what you’d actually use.
To test your own card, choose it under “Your current card” in our credit card calculator: it shows where the card ranks on your spending and whether its fee pays off.
What does a credit card cash advance cost?
A $500 cash advance repaid after 30 days costs a median of $36.91 across the 106 cards in our records that publish their cash advance terms: a median fee of $25 plus interest at a median cash APR of 28.99%. Interest generally starts on the day of the advance, with no grace period. (Source: CFPB) The median cash APR is higher than the median top of the purchase APR range, 28.49%. 4 cards, all from PenFed, charge no cash advance fee.
What do foreign transaction fees cost?
A 3% foreign transaction fee adds $60 to every $2,000 spent abroad or with an overseas merchant (an illustration, not an average trip). Of the 128 US cards in our records that state the fee, 43 charge 3%, 3 charge less, and 82 charge nothing. If you travel or buy from overseas sites, a card without the fee avoids it entirely.
Why can interest appear after you pay a card off?
Interest keeps building between the statement date and the day your payment arrives. On $4,350 at 22.36%, the 21 days between a statement closing and its due date add about $55.96, which appears on the next statement. Ask your issuer for a payoff amount that includes it: see residual interest after payoff.
Is a “no interest if paid in full” offer the same as 0% APR?
No. A deferred-interest promotion, common on store cards, charges interest back to the purchase date if the balance isn’t paid in full by the deadline: the CFPB warns that you “could have to pay all of the interest that you expected to be deferred”. (Source: CFPB) A true 0% intro APR charges no interest for the intro period, and interest starts only on what’s left after it.
Our view: the mistakes that cost most are about time, not fees
The lists of credit card mistakes we read, from CNBC Select and Bankrate, give each mistake a numbered place without its cost. Our numbers say the mistakes are far from equal. On the average balance, paying only the minimum costs $7,030, and carrying a balance costs $973 every year it lasts. A single late fee is $41 at most, but the penalty APR it can trigger costs up to $848 a year. A cash advance or a foreign transaction fee costs tens of dollars.
So we think the order of priority is clear. First, pay at least the minimum on time, every month: autopay for the minimum prevents the late fee, the penalty APR and the credit report damage together. Second, pay down any balance as fast as you can, and move it to a lower rate if that clears it sooner. Only then do rewards, annual fees and foreign transaction fees matter. This would change if card rates fell sharply, or for someone who never carries a balance, for whom fees and rewards are the whole picture.
How we priced each mistake
The example balance is the New York Fed’s average credit card balance per person with a credit report; the APR is the Federal Reserve’s average on accounts charged interest (see credit card statistics). Card terms come from the issuers’ own pages, saved and checked automatically: late fees and penalty APRs are quoted word for word from each issuer’s pricing table, and cover only the cards whose saved pages include it. Interest is worked out monthly at the APR divided by 12, with no new spending. Rewards use the BLS Consumer Expenditure Survey’s middle-income household, as on our homepage.
We haven’t priced mistakes that have no reliable dollar figure, such as how closing a card or applying for several affects a credit score. For card security, including what the law caps your loss at, see our credit card security guide.
