Calculation method: This calculator uses a simplified monthly-interest model (APR ÷ 12). Credit-card issuers may calculate interest using daily periodic rates and average daily balances, so your actual statement may differ. See our methodology.
Credit Card Payoff Calculator
Your estimated payoff date depends on three things: your balance, your APR, and your fixed monthly payment. The calculator above shows how many months it will take to pay off your credit card, the month you'd reach zero, your total interest, and how much sooner an extra $50 a month would get you there. For example, $5,000 at 22.99% APR paid off at $175 a month takes about 42 months. Have a deadline instead? Switch the calculator to "payment to be debt-free by a date" to see the monthly payment you need.
"How long is this going to take?" is the question most people carrying card debt want answered — not an abstract rate, but a date on the calendar. This calculator estimates that date, plus the total cost of getting there.
How the Calculator Works
Enter your current balance, APR, and the fixed amount you plan to pay every month. The calculator runs a month-by-month simulation: each month it adds interest on the remaining balance (APR ÷ 12), applies your payment, and carries the new balance forward. It stops when the balance hits zero and reports:
- Your estimated payoff date and how many months it takes
- Total interest and total amount paid
- A chart of your balance declining over time
- An automatic comparison showing what adding $50 a month would change
- Milestones: the month you reach 25%, 50%, 75%, 90% and 100% paid off
- A month-by-month schedule you can download as a CSV file or print
Still using the card? Enter the purchases you expect to keep making in New charges each month. The calculator adds them to the balance at the start of every month, before interest, until the card is paid off. Leave it at $0 if you've stopped using the card.
Formula
New Balance = Balance + New Charges + Monthly Interest − Payment
Repeat until New Balance ≤ 0 → months to payoff
This is a simplified estimate, not an issuer-specific statement calculation. A closed-form version is n = −ln(1 − B·r ÷ P) ÷ ln(1 + r), where r = APR ÷ 12, B = balance, and P = payment, with no new charges.
Example: $5,000 at 22.99% APR, paying $175 a month
| Month | Payment | Interest | Principal | Balance |
|---|---|---|---|---|
| 1 | $175.00 | $95.79 | $79.21 | $4,920.79 |
| 2 | $175.00 | $94.27 | $80.73 | $4,840.07 |
| 3 | $175.00 | $92.73 | $82.27 | $4,757.79 |
| 12 | $175.00 | $77.40 | $97.60 | $3,942.66 |
| 24 | $175.00 | $52.45 | $122.55 | $2,614.93 |
| 36 | $175.00 | $21.10 | $153.90 | $947.63 |
| 42 (final) | $135.32 | $2.54 | $132.78 | $0.00 |
At $175 a month, payoff takes about 42 months (3 years, 6 months) and roughly $2,310 in interest. Adding $50 (a $225 payment) cuts that to about 30 months and $1,577 in interest — 12 months sooner and about $734 saved.
How Much to Pay to Be Debt-Free in 1, 2 or 3 Years
In "debt-free by a date" mode the calculator works backward from your deadline using the standard payment formula: Payment = Balance × r ÷ (1 − (1 + r)−n), where r is APR ÷ 12 and n is the number of months.
| Balance | 12 months | 24 months | 36 months |
|---|---|---|---|
| $3,000 | $282.22 | $157.11 | $116.12 |
| $5,000 | $470.36 | $261.85 | $193.53 |
| $10,000 | $940.72 | $523.69 | $387.05 |
Stretching $5,000 from 12 to 36 months cuts the payment by more than half but triples the interest, from about $644 to about $1,967.
How Many Months Until Each Milestone?
| Milestone | Reached at | Balance remaining |
|---|---|---|
| 25% paid off | Month 14 | $3,742 |
| 50% paid off | Month 25 | $2,490 |
| 75% paid off | Month 35 | $1,102 |
| 90% paid off | Month 39 | $468 |
| Paid off | Month 42 | $0 |
The first quarter takes 14 months, but the last quarter takes only 7, because less of each payment goes to interest as the balance falls.
What New Charges Do to the Payoff Date
Keep spending $50 a month on the same card and the same $175 payment takes 78 months instead of 42, with about $4,745 in interest instead of $2,310. In month 1, the $50 is added first ($5,050), interest is $96.75, and the balance after the $175 payment is $4,971.75. At $100 a month of new charges, $175 no longer covers the charges plus interest, so the balance never reaches zero.
| New charges each month | Time to pay off | Total interest |
|---|---|---|
| $0 | 42 months | $2,310 |
| $50 | 78 months | $4,745 |
| $100 | Never | — |
If the Answer Is "Never"
If your payment doesn't cover the monthly interest (balance × APR ÷ 12, about $96 in this example), the balance never goes down. The calculator says so and shows the payment you need to start making progress.
Why Payoff Isn't a Straight Line
Because interest is charged on whatever balance remains, early payments are mostly interest and later payments are mostly principal. That's why a balance can feel stuck for the first year before it starts dropping visibly — the table above shows the principal share growing each month.
When the Result May Differ
Treat the results as a planning estimate. Your real numbers can differ because of:
- Daily periodic rate: many issuers apply APR ÷ 365 (or 360) each day instead of APR ÷ 12 once a month, which can produce different interest.
- Average daily balance: your balance moves during the cycle as purchases post and payments arrive; this calculator uses a single month-start balance.
- Fees: annual, late, foreign-transaction, cash-advance, and balance-transfer fees aren't included unless the calculator asks for them.
- New purchases: the estimate assumes you stop adding charges unless you enter them under New charges each month, and then it assumes the same amount every month.
- Grace period: whether new purchases accrue interest depends on whether you pay your statement balance in full and on your card's terms.
- Different APR categories: purchases, balance transfers, cash advances, and penalty APRs can carry different rates on the same card, and how payments are allocated between them affects the total.
- Payment changes: the calculator assumes the same payment every month. Skipped, late, or larger payments change the date.
Your statement and cardholder agreement are the final word. See our methodology for how every calculator on this site works.

Frequently Asked Questions
How long will it take to pay off my credit card?
It depends on your balance, APR, and monthly payment. For example, a $5,000 balance at 24% APR with $150 monthly payments takes about 56 months (4 years, 8 months) and roughly $3,300 in interest under the simplified monthly model. Enter your own numbers above for an estimated payoff date.
How much should I pay to pay off my credit card in a year?
Choose "payment to be debt-free by a date" above and enter 12 months. For example, $5,000 at 22.99% APR takes about $470 a month to clear in 12 months, $262 a month for 24 months, or $194 a month for 36 months, assuming no new charges.
What's the smallest payment that makes progress?
Your payment has to be larger than one month's interest, estimated here as balance × (APR ÷ 12). On $5,000 at 22.99%, that's about $96 a month; anything above it starts reducing the balance, and the calculator tells you if your payment falls short.
Does paying more than the minimum really make a big difference?
Yes. Extra money goes straight to principal, which reduces the interest charged every month after. On a $5,000 balance at 22.99% APR, raising the payment from $175 to $225 cuts payoff by about a year and saves over $700 in interest in this calculator's estimate.
Should I pay off my credit card in full or make payments?
On cards with a grace period, paying your full statement balance by the due date typically avoids interest on purchases. If you can't pay in full, paying as much above the minimum as your budget allows shortens payoff and reduces interest.
Why is my estimated payoff date different from my statement's?
Many U.S. statements show how long payoff would take at the minimum payment, while this calculator uses the fixed payment you enter. It also uses a simplified monthly model (APR ÷ 12), while issuers may use a daily rate and average daily balance.
Does this calculator account for new purchases?
Yes, if you enter them. Put the purchases you expect to keep making in "New charges each month" and the calculator adds them to the balance every month before interest. For example, $5,000 at 22.99% APR paid at $175 a month takes 42 months with no new charges, but 78 months with $50 of new charges each month.
What if my APR changes?
Most card APRs are variable, so your rate can move with benchmark rates. The calculator assumes one fixed APR; re-run it with the new rate if yours changes.
This calculator provides estimates for educational purposes only and is not financial, tax, or legal advice. Most results use a simplified monthly-interest model (APR ÷ 12); your card issuer may use a daily periodic rate and average daily balance, plus its own fees and grace period rules, so your actual figures may differ — always confirm against your official statement.
