About This Calculator
Credit cards typically carry high interest rates, so paying only the minimum can take years and cost far more than the original balance. This calculator shows how long it will take to pay off your card at a fixed monthly payment, and how much total interest you'll pay.
How This Is Calculated
n = −log(1 − (B·r)/M) / log(1 + r)
- B
- — Current balance
- r
- — Monthly interest rate (APR ÷ 12)
- M
- — Fixed monthly payment
A $5,000 balance at 24% APR with a $200/month payment takes about 32 months to pay off, costing roughly $1,376 in interest.
Assumptions
- Assumes a fixed payment and fixed APR — promotional 0% rates or rate changes will alter results.
- Assumes no new charges are added to the balance.
