How to use this calculator
- Enter your current balance. Use the balance on your latest statement, or today's balance from your card app.
- Enter your APR. It's printed on your statement next to “Annual Percentage Rate”. If you have several rates (purchases, cash advances, a promo rate), use the purchase APR — or run the calculator once per balance.
- Choose your goal. Pick Pay a fixed amount to see when a payment you can afford will clear the debt, or Pay off by a date to find the payment needed to be debt-free in a set number of months.
- Read the results. You'll see your payoff date, total interest, the interest you save compared with minimum payments, a balance chart and a year-by-year schedule. Use Copy link to save or share your plan.
How credit card interest is calculated
Your APR is a yearly rate, but card issuers charge interest daily. Most divide the APR by 365 to get a daily periodic rate, multiply it by your average daily balance for the billing cycle, and then multiply by the number of days in the cycle. At 22.99% APR, the daily rate is about 0.063%, so a $6,500 balance costs roughly $4.09 a day — about $124.50 a month.
Two rules make a big difference:
- The grace period. If you pay your full statement balance by the due date, you normally pay no interest on new purchases. Once you carry a balance, you lose the grace period and interest starts on new purchases from the day you make them.
- Interest compounds. Unpaid interest becomes part of the balance, so next month you pay interest on last month's interest. That's why small payments barely dent a high-APR balance.
The CFPB’s credit card guides cover grace periods and fees in more detail. This calculator applies interest monthly at APR ÷ 12, the standard way to model card payoff. The result is typically within a few dollars of what your issuer's daily method produces.
Why minimum payments take so long
Many large issuers set the minimum payment at 1% of the balance plus that month's interest (with a floor of around $25–$40). Because the minimum shrinks as your balance shrinks, most of every payment goes to interest, and the debt drags on for decades. That's why the Credit CARD Act requires your statement to show how long payoff will take at the minimum, and the payment needed to pay it off in three years. Our minimum payment calculator recreates that warning for your card.
| Monthly payment | Time to pay off | Total interest |
|---|---|---|
| Minimum only (starts at $189.53) | 21 years 6 months | $11,363 |
| $200 fixed | 4 years 4 months | $3,771 |
| $250 fixed | 3 years 1 month | $2,582 |
| $300 fixed | 2 years 5 months | $1,979 |
| $400 fixed | 1 year 8 months | $1,363 |
| $500 fixed | 1 year 4 months | $1,047 |
Notice that a fixed $200 payment — only about $10 more than the first minimum — cuts the payoff time from over 21 years to just over 4, and saves more than $7,500 in interest. The single most powerful move is to keep paying the same dollar amount every month instead of letting your payment fall with the minimum.
Worked example
Maria owes $6,500 on a card charging 22.99% APR. Her first month's interest is $6,500 × 22.99% ÷ 12 = $124.53. If she pays $250, $125.47 goes to principal and her balance drops to $6,374.53. Next month's interest is a little smaller, so a little more of her $250 goes to principal — and the process accelerates.
At $250 a month, Maria is debt-free in 37 months and pays $2,582 in interest. If she wants to be done in 24 months, she needs to pay $340.39 a month; to finish in 12 months, $611.46. Moving the balance to a 0% balance-transfer card could save even more — run the numbers with our balance transfer calculator.
7 ways to pay off a credit card faster
- Fix your payment. Pick a dollar amount and keep paying it even as the minimum falls.
- Stop adding new charges. Switch day-to-day spending to debit or cash until the card is clear.
- Target one card at a time. Pay minimums everywhere and throw all extra money at the highest APR (avalanche) or smallest balance (snowball). Compare both with the debt payoff calculator, or read debt avalanche vs snowball.
- Ask for a lower APR. If you've paid on time for a year, call your issuer and ask. Even a few points matter on a large balance.
- Use a 0% balance transfer. Transfer fees are usually 3%–5%, but 15–21 interest-free months can save far more. Aim to clear the balance before the promotion ends.
- Consider a consolidation loan. A fixed-rate personal loan at a lower APR gives you one payment and a set end date. Check the true cost, including origination fees, with the debt consolidation calculator. Our guide to balance transfer vs personal loan compares the two.
- Put windfalls to work. Tax refunds, bonuses and side-income payments applied directly to principal shorten the payoff dramatically.
The formula behind the numbers
With a monthly rate r = APR ÷ 12, balance B and fixed payment P:
If the payment P is less than or equal to the first month's interest (r·B), the balance never goes down and the calculator will tell you. Total interest is the sum of each month's interest charge until the balance reaches zero; the final payment is usually a little smaller than the others.
Minimum payment calculator
Find your credit card minimum payment, how long it takes to pay off the card if you only ever pay the minimum, and how much interest that costs. Then compare it with the payment that clears the balance in three years, the same comparison your statement’s minimum payment warning shows.
How to use this calculator
- Enter your balance and APR from your latest statement.
- Choose how your minimum is calculated. Your card agreement explains the formula. If you’re not sure, compare the first minimum shown here with the one on your statement.
- Enter the floor, the lowest minimum your issuer charges.
- Read the warning table. It compares paying only the minimum with paying the card off in three years.
The calculator assumes you make no new purchases and the APR doesn’t change.
How minimum payments are calculated
Every issuer sets its own formula, which is in your card agreement. The most common are:
- A percentage of the balance plus interest: usually 1% of the balance plus the month’s interest charge and any fees. This guarantees each payment reduces the balance a little.
- A flat percentage of the balance: often 2% to 4%, which includes the interest.
- A dollar floor: if the formula gives less than the floor, often $25 to $40, you pay the floor, or the whole balance if it’s smaller.
Past-due amounts and fees such as a late fee are usually added on top. On a $5,000 balance at 22.99% APR, the first minimum payment under common formulas is:
| Formula ($35 floor) | First minimum | Time to pay off | Total interest |
|---|---|---|---|
| 1% of the balance plus interest | $145.79 | 16 years 7 months | $8,053 |
| 2% of the balance | $100.00 | Never | — |
| 3% of the balance | $150.00 | 15 years 8 months | $7,484 |
| 4% of the balance | $200.00 | 9 years 10 months | $4,119 |
The minimum payment warning on your statement
Under the Credit CARD Act of 2009, every monthly credit card statement must include a minimum payment warning (Regulation Z §1026.7). It shows how long it would take to pay off your current balance if you paid only the minimum, and the total you’d pay. It also shows the monthly payment that would pay the balance off in three years, the total cost at that payment and how much you’d save.
This calculator rebuilds that comparison from your numbers. Your statement’s figures may differ slightly, because issuers calculate interest daily and round the payoff time.
Worked example
A $5,000 balance at 22.99% APR, with a minimum of 1% of the balance plus interest and a $35 floor:
- The first minimum is $145.79, and 66% of it is interest.
- Paying only the minimum takes 16 years 7 months and costs $8,053 in interest, for $13,053 in total.
- Paying $193.52 a month instead clears it in 3 years for $6,967, saving $6,086.
Minimum payments on common balances

Why paying the minimum takes so long
The minimum payment falls as your balance falls. Early on, most of each payment covers interest, and as the balance shrinks, so does the payment, so you never build up speed. With a “1% plus interest” formula, only about 1% of the balance is repaid each month, which stretches a typical balance over many years. The final years are spent paying the floor.
The fix is simple: keep paying the same dollar amount even as the minimum drops. Our credit card payoff calculator shows how fast a fixed payment clears the card.
How to get out of the minimum payment trap
- Pay a fixed amount. Start with the 3-year payment shown above, or whatever you can afford above the minimum, and don’t let it fall.
- Cut the rate. A 0% balance transfer or a lower-rate consolidation loan means more of each payment goes to the balance. Include the fees when you compare.
- Focus on one card at a time. Pay minimums on the rest and put every extra dollar on the highest-APR card. The debt payoff calculator builds the plan.
- Ask for help early. If you can’t make the minimum, call your issuer about hardship programs, or contact a nonprofit credit counseling agency before you fall behind.
Our guide to how credit card interest is calculated explains the daily rate and grace period behind these numbers.
How credit card interest is calculated
Your credit card statement shows an annual percentage rate (APR), but card issuers don’t charge interest once a year. They charge it every day, based on your balance, and add it to your bill each month.
Understanding the mechanics explains:
- why your balance can grow even when you make payments;
- why paying in full matters so much;
- why you might see “trailing interest” after paying off a card.
Step 1: From APR to a daily rate
Most issuers convert your APR into a daily periodic rate (DPR) by dividing by 365. Some use 360, which slightly increases the cost:
Daily periodic rate = APR ÷ 365
At 22.99% APR, the daily rate is about 0.063%. It sounds tiny, but it applies every day of the year.
Step 2: Your average daily balance
Most issuers use the average daily balance method, including new purchases:
- Take your balance at the end of each day in the billing cycle, adding purchases and fees and subtracting payments and credits.
- Add those daily balances together.
- Divide by the number of days in the cycle.
Example. A 30-day billing cycle:
- Your balance is $6,000 for the first 20 days.
- On day 21 you make a $1,000 payment, so the balance is $5,000 for the last 10 days.
- Average daily balance = (20 × $6,000 + 10 × $5,000) ÷ 30 = $5,666.67.
Timing matters. The same $1,000 paid on day 5 instead of day 21 would lower the average, and the interest, more.
Step 3: The interest charge
Interest = average daily balance × daily periodic rate × days in the billing cycle
Continuing the example at 22.99% APR:
$5,666.67 × (0.2299 ÷ 365) × 30 = $107.08 of interest for the cycle.
Many issuers effectively compound daily, adding each day’s interest to the balance before the next day’s calculation. That’s why the effective annual cost is slightly higher than the APR.
Why do minimum payments barely move the balance?
With a balance of $6,500 at 22.99%, interest is about $124 a month. A typical minimum payment is 1% of the balance plus that month’s interest, about $190 at first. So only about $65 of it actually reduces what you owe.
Because the minimum shrinks as your balance falls, paying only the minimum can take more than 20 years. The credit card payoff calculator shows how much faster a fixed payment gets you out.
The grace period: how to pay zero interest
Most cards offer a grace period on purchases, usually at least 21 days between the statement date and the due date. If you pay your full statement balance by the due date, you pay no interest on purchases.
The catch: once you carry a balance past the due date, you usually lose the grace period. New purchases then start accruing interest from the day you make them, until you’ve paid the balance in full, often for two consecutive billing cycles, to restore it.
What is trailing (residual) interest?
Suppose you carry a balance, then pay the statement balance in full. The next statement may still show a small interest charge. That’s trailing interest: interest that built up between the statement date and the day your payment arrived.
To stop it, call your issuer for a payoff amount that includes interest through the payment date, or pay a little more than the statement balance.
Different balances, different rates
One card can carry several balances at different APRs: purchases, balance transfers, cash advances, and a penalty rate if you pay late. Federal rules (the Credit CARD Act) set how your payments are applied:
- The minimum payment can be applied to whichever balance the issuer chooses, often the lowest-rate balance.
- Anything you pay above the minimum must go to the balance with the highest APR first.
Cash advances are especially expensive. They usually carry a higher APR, have no grace period (interest starts immediately), and come with a fee of around 3%–5%.
Penalty APRs
If your payment is 60 or more days late, an issuer can generally apply a penalty APR, often around 29.99%, to your existing balance. If you then make the next six minimum payments on time, federal rules generally require the issuer to restore the earlier rate on that existing balance. Set up autopay for at least the minimum so it never happens.
How to pay less interest
- Pay in full every month to keep your grace period.
- Pay early. Payments made earlier in the cycle lower your average daily balance.
- Pay more than the minimum, and keep your payment fixed even as the minimum falls.
- Ask for a lower APR. A good payment history gives you leverage.
- Move the balance to a 0% balance transfer card. Check the fee and the promotion length with the balance transfer calculator.
- Target your highest-APR card first if you have several, using the avalanche method in our debt payoff calculator.
