Your card and payoff goal
- Monthly rate r = 21.5% ÷ 12 = 1.7917% per month
- Month 1 interest = $6,500.00 × 1.7917% = $116.46; month 1 principal = $225.00 − $116.46 = $108.54
- Payoff months N = ceil(−ln(1 − $6,500.00 × 1.7917% ÷ $225.00) ÷ ln(1 + 1.7917%)) = 42
- Total paid across 41 full payments of $225.00 + last payment $11.32 = $9,236.32
- Total interest = $9,236.32 − $6,500.00 = $2,736.32

Level payments for 12 to 60 months on $6,500.00 at 21.5% APR. The 36-month row ($246.56/mo) matches the 3-year box under 12 CFR 1026.7(b)(12).
How it works
Divide your card's APR by 12 to get the monthly rate r. On $6,500 at 21.5% APR, r is 1.7917% a month. Month 1 adds $6,500 × 1.7917% = $116.46 of interest. Only the rest of your payment lowers the debt.
When you enter a fixed payment M above the first month's interest, the exact month count is −ln(1 − B × r ÷ M) ÷ ln(1 + r). We round up to a whole month N. At $225 a month on $6,500 at 21.5% APR, you make 41 payments of $225.00 and a 42nd payment of $11.32.
When you pick a target month count N, the level payment is B × r ÷ (1 − (1 + r)^−N). At 0% APR it is B ÷ N. Clearing $6,500 at 21.5% APR in 24 months takes $335.61 a month and $1,554.53 of interest.
How the 3-year box on your statement works
Under 15 U.S.C. 1637(b)(11) and Regulation Z, 12 CFR 1026.7(b)(12), your monthly bill must show a Minimum Payment Warning box. When paying only the minimum takes more than 3 years after rounding, the box adds a 36-month row. It shows the level payment that clears the card in 3 years, the 3-year total cost, and what you save against the minimum.
Appendix M1 and the SAS program in Appendix M2 work that 3-year payment from the present-value annuity factor at your card's periodic rate. Comment 7(b)(12)-1 lets your card company round every dollar figure in the box to whole dollars or to cents. On $6,500 at 21.5% APR, the exact 36-month payment is $246.56 a month ($247 in whole dollars). Total cost is $8,876.15, with $2,376.15 in interest.
Why a fixed payment beats a falling minimum
Regulation Z sets the warning line on your bill: "Minimum Payment Warning: If you make only the minimum payment each period, you will pay more in interest and it will take you longer to pay off your balance;" (12 CFR 1026.7(b)(12)(i)(A)). In Appendix M1 (b)(1), card issuers apply the minimum payment formula in the cardholder agreement, such as 1% of the balance plus the month's interest or 2% of the balance with a $20 floor.
Because a minimum falls as the balance drops, you pay off less principal each month. On $6,500 at 21.5% APR, month 1 interest is $116.46 and 1% of the balance is $65.00, for a first minimum of $181.46. Locking in $225.00 every month clears the card in 42 months ($2,736.32 interest). Paying $325.00 a month (+$100) finishes in 25 months ($1,620.19 interest) and saves $1,116.13.
Payment allocation and daily interest
Two rules affect how fast your payment works in practice. First, under 12 CFR 1026.53(a), when you pay more than the required minimum, the card issuer "must allocate the excess amount first to the balance with the highest annual percentage rate." Any money left goes to the other balances from highest APR to lowest. You can see that bucket split in the credit card payment allocation calculator.
Second, CFPB Ask CFPB answer 51 notes that "Many credit card companies calculate the interest you owe daily, based on your average daily account balance." Once you carry a balance, paying earlier in the billing cycle lowers that daily average and trims the month's interest. Check one cycle's charge in the credit card interest calculator.

Read the transcript
How long will your card take to pay off
0:00 A card balance of $6,500 at 21.5% takes 42 months to clear, if you keep on paying $225 every month.
0:11 A fixed monthly payment sets the date; the interest sets the price.
0:15 But the very first payment is mostly interest.
0:18 about $116 of the money you send in that very first payment goes to interest; only about $109 of it comes off the balance that you owe.
0:29 Less than half of that first payment reduces the balance.
0:32 So out of everything you pay, about $2,700 goes to interest over the whole schedule, and you pay about $9,200 in all.
0:41 Interest makes paying off the card cost more than that balance.
0:45 You control the monthly payment, not the interest rate.
0:49 The card's interest rate and how big the balance is decide everything else.
How the interest is charged
0:54 Each month, the card charges interest on whatever you still owe.
0:57 The charge shrinks as the balance falls.
1:00 The APR, the yearly rate it charges, is divided by 12, and on this balance the first month's interest is about $116.
1:10 Here, month by month, the interest shrinks and the balance falls, until payment 42 clears the balance and leaves it at zero.
What the balance does each month
1:18 The balance falls slowly at first, then faster as the months go by.
1:22 By month 25, $3,250 of it is gone.
1:27 The last payment is about $11, not a full payment, because the balance, about that much, is all that remains.
1:34 The schedule ends with a zero balance.
What a bigger payment saves
1:37 On the same balance at the same rate, a bigger monthly payment saves interest: $275 a month finishes in 32 months and saves about $700 of interest in all.
1:50 Every dollar above the interest comes straight off the balance.
1:53 The interest charges tell the same story: about $2,000 on the same balance you started with.
2:00 The smaller monthly payment needs 10 months more to clear the balance.
2:04 In the end, paying more becomes the cheaper option overall.
Your own balance and payment
2:08 Now, your own card.
2:10 Switch the goal to a target time; the page calculates the monthly payment instead.
2:15 Enter $12,000 at 24.9%, and 18 months to pay off that whole balance.
2:21 The page recalculates as you type, with no button to press.
2:25 The results follow at once on the page: about $806 a month clears the card in 1 year 6 months, and the interest in total is about $2,500.
2:36 That is another card entirely: a target time, not a fixed monthly payment.
What the box on your bill means
2:42 If your statement has a 36-month box, it shows the payment that clears the card.
2:48 On this balance that is about $247 a month.
2:52 Your statement's box shows a benchmark payment, not a bill.
2:56 The CFPB's page on that box says no additional payment beyond the minimum is required of you.
3:02 The interest charge shrinks as the balance falls, and a bigger payment saves interest.
3:07 Your monthly payment decides how many months it takes.
3:10 Check your own card at fastcalc.us.
Formula
r = APR ÷ 12 first-month interest = B × r fixed payment mode: N = ceil(−ln(1 − B × r ÷ M) ÷ ln(1 + r)) target months mode: M = B × r ÷ (1 − (1 + r)^−N) (or B ÷ N at 0% APR) final payment = (B − M × (1 − (1 + r)^−(N − 1)) ÷ r) × (1 + r)^N total paid = (N − 1) × M + final payment total interest = total paid − B B card balance · r monthly rate · M monthly payment · N number of payments
Example
Fixed $225 payment on $6,500 at 21.5% APR. Month 1 charges $116.46 in interest, so $108.54 comes off the balance. You make 41 payments of $225.00 and a 42nd payment of $11.32. You are debt-free in 3 years 6 months and pay $2,736.32 in interest ($9,236.32 in all).
24-month target on $5,400 at 17.0% APR. Clearing a $5,400 balance at 17.0% APR in 24 months takes $266.99 a month ($6,407.72 in all, with $1,007.72 in interest). Stretching the same $5,400 to 36 months lowers the payment to $192.52 a month, which raises interest to $1,530.89.
$9,500 at the August 2026 Federal Reserve rate of 22.36%. Suppose you owe $9,500 at 22.36% APR and pay $332.14 a month. Month 1 interest is $177.02. It takes 41 payments of $332.14 and a 42nd payment of $79.71, for $4,197.45 in interest. At the 21.19% all-accounts average, the same payment takes 41 months and $3,846.20 in interest.
Assumptions and limitations
- Interest is added once a month at APR ÷ 12. Regulation Z Appendix M1 (b)(4)(vii) allows this monthly rate or a daily rate of APR ÷ 365 across 30.41667-day months.
- You add no new purchases, cash advances, or fees while paying the card off. As CFPB Ask CFPB answer 36 notes, statement payoff amounts "do not take into consideration any future purchases."
- In fixed-payment mode, you pay the same amount each month until the final cycle. In the last month you pay only the balance left plus that month's interest, so the card ends at $0.00 (Appendix M1 (b)(4)(v)).
- One fixed APR applies to the whole balance. The 21.5% default sits between the two August 2026 rates in the Federal Reserve G.19 release: 21.19% for all accounts and 22.36% for accounts assessed interest.
- If a card carries several APR buckets, 12 CFR 1026.53(a) sends every dollar above the minimum to the highest-APR bucket first.
These figures are estimates for learning and planning, not financial, tax, legal or investment advice. Terms of use.
What to do with the result
Stop putting new purchases on the card you are paying down. Once you carry a balance, new charges usually lose their grace period and add interest from day one. Keeping $6,500 free of new spending lets a $225.00 payment clear the debt in 42 months.
Automate a fixed payment above the 36-month box amount. On $6,500 at 21.5% APR, paying $275.00 instead of $225.00 (+$50 a month) cuts 10 months off the schedule and saves $707.35 in interest. You can also test a one-time lump sum in the loan extra payment calculator.
Compare a 0% balance transfer or a fixed-rate loan. Moving $6,500 from 21.5% APR can cut interest if the transfer fee is smaller than the interest you would pay; check the balance transfer calculator and the personal loan calculator.
Send your payment earlier in the billing cycle. Because issuers track your average daily account balance, paying $225.00 fifteen days early saves about $2.01 in the first month at 21.5% APR.
Call your card company right away if you cannot afford the payment. CFPB Ask CFPB answer 1697 notes that "Many card companies are willing to work with you to change your payment if you’re facing a financial emergency." You can also call the toll-free credit counseling number in your statement's warning box.
Frequently asked questions
How is credit card interest calculated each month?
Appendix M1 to Regulation Z uses a monthly rate of APR ÷ 12, or a daily rate of APR ÷ 365 across 30.41667-day months. On $6,500 at 21.5% APR, the monthly rate is 1.7917%. That adds $116.46 of interest in month 1.
Why is my final credit card payment smaller than the rest?
A fixed payment rarely divides the balance and interest into a whole number of months. On $6,500 at 21.5% APR with a $225.00 payment, 41 payments leave $11.12 of principal. Month 42 adds $0.20 of interest, so a final payment of $11.32 brings the balance to $0.00.
What does the 3-year payoff box on my credit card bill mean?
Under 15 U.S.C. 1637(b)(11) and 12 CFR 1026.7(b)(12), your bill must show the level payment that clears your balance in 36 months when minimum payments would take over 3 years. On a $5,000 balance at 22.0% APR, that 36-month payment is $190.95 a month ($191 rounded to the dollar) and costs $1,874.28 in interest.
Do I have to pay the 36-month amount shown on my statement?
No. CFPB Ask CFPB answer 36 states: "You do not have to pay any more than the minimum amount shown on your statement." Still, paying $246.56 instead of $225.00 on $6,500 at 21.5% APR finishes 6 months sooner and saves $360.17.
What happens if my payment is less than the monthly interest?
The debt grows each month because unpaid interest is added to the balance. Under 12 CFR 1026.7(b)(12)(ii)(A), your bill must warn that "you will never pay off the balance shown on this statement because your payment will be less than the interest charged each month." On $6,500 at 21.5% APR, any payment of $116.46 or less fails to reduce the balance.
How are extra payments split across balances with different APRs?
Under 12 CFR 1026.53(a), every dollar you pay above the required minimum goes first to the balance with the highest APR. In comment 53(a)-5.i's example — $500 at 20% APR and $1,500 at 15% APR — an $800 extra payment clears the $500 balance first and sends $300 to the 15% balance.
What is the average credit card interest rate in 2026?
In the Federal Reserve G.19 release of October 7, 2026 (for August 2026), commercial bank credit cards averaged 21.19% across all accounts and 22.36% on accounts assessed interest. In 2025 those averages were 21.22% and 22.32%. On $6,500 paid at $225.00 a month, 21.19% APR costs $2,673.17 in interest (41 months), while 22.36% APR costs $2,918.97 (42 months).
