Quick answer
Each month the balance becomes balance × (1 + APR ÷ 12) − payment. A $5,000 balance at 18% APR with $200 monthly payments takes 32 months (2 years 8 months), costs $1,313.96 in interest and totals $6,313.96.
Enter the balance, APR and monthly payment. The calculator returns months to pay off, total interest and total paid. Use this credit card payoff calculator to check your own figures.

Formula and method
Formula
each month: balance ← balance × (1 + APR ÷ 12) − payment
IEEE-754 double precision; money shown to cents, rates to 4 decimals. Results are estimates, not financial advice.
Simulates month by month until the balance is cleared; the payment must exceed the first month's interest.
Worked examples
These examples are verified: each one is an automated test case that the live calculator must reproduce exactly.
Example 1
Inputs: Balance = 5000; APR = 18; Monthly payment = 200.
| Result | Value |
|---|---|
| Months to pay off | 32 |
| Total interest | $1,313.96 |
| Total paid | $6,313.96 |
| Time | 2 years 8 months |
Example 2
Inputs: Balance = 12000; APR = 24.99; Monthly payment = 500.
| Result | Value |
|---|---|
| Months to pay off | 34 |
| Total interest | $4,806.40 |
| Total paid | $16,806.40 |
| Time | 2 years 10 months |
Example 3
Inputs: Balance = 1000; APR = 0; Monthly payment = 100.
| Result | Value |
|---|---|
| Months to pay off | 10 |
| Total interest | $0.00 |
| Total paid | $1,000.00 |
| Time | 10 months |
The first line is the headline result (months to pay off). Below it the credit Card Payoff Calculator lists total interest, total paid and time, which describe the same case from other angles. IEEE-754 double precision; money shown to cents, rates to 4 decimals. Results are estimates, not financial advice.
Paying more helps a lot
At $300 a month the same balance clears in about 20 months with roughly $800 of interest (see the calculator for the exact figure). The payment must exceed the first month's interest ($75 here), or the balance never falls.
Stop adding purchases
The calculation assumes no new purchases or fees and a fixed APR. Balance transfers at a lower rate or consolidation loans can cut interest, but check fees.
How the result changes with balance
Holding every other input at the first worked example, this table changes only balance. It shows how sensitive the answer is to that one value; each row was produced by running this calculator.
| Balance | Months to pay off | Total interest | Total paid |
|---|---|---|---|
| 2500 | 14 | $289.31 | $2,789.31 |
| 5000 | 32 | $1,313.96 | $6,313.96 |
| 10000 | 94 | $8,622.36 | $18,622.36 |
What happens with invalid input
These messages are produced by the calculator itself, so you know what to fix.
- Monthly payment: entering "50" shows "The payment must exceed the first month's interest ($83.33), or the balance never falls." beside that field and no result.
- Balance: entering "0" shows "Balance must be greater than 0." beside that field and no result.

Background: personal finance estimates
Financial calculators project from the numbers you give them. Long-range tools depend on guesses about returns and tax rates that are unlikely to hold exactly, payoff tools assume a fixed payment and rate, and tax or salary results depend on the tax year, filing status and country. Official calculators say their output is for reference only.
For decisions that matter, use conservative inputs and check the figures against your lender, plan documents or a qualified adviser.
Assumptions and limitations
- Payment must exceed monthly interest
Results are estimates for planning, not financial advice. Lender terms, fees, taxes and rounding rules can change real figures, so confirm important numbers with your lender or a licensed adviser.
If a required value is empty, not a number, or outside its allowed range, the form marks that field with a message and shows no result instead of a misleading number. The automated checks deliberately try invalid entries for monthly payment and balance to confirm this.
