What is the credit card payoff calculator?

In short

A $5,000 credit card balance at 24% APR takes 8.5 years to pay off at a $120 minimum payment — and costs $3,365 in interest. Raise the payment to $200/month and it's gone in 2.5 years with only $954 in interest. Your payment must exceed the monthly interest charge (balance × APR ÷ 12 = $100/month at 24% on $5,000) or the balance never falls. Every extra dollar above the interest threshold directly reduces what you owe.

This credit card payoff calculator shows how long it takes to clear your balance at a given monthly payment, and how much interest you'll pay — so you can see the impact of paying more each month.

How to use this calculator

  1. 1Enter your current balance.
  2. 2Set the card's APR.
  3. 3Enter your planned monthly payment.
  4. 4See the payoff time and total interest.
  5. 5Increase the payment to see how much faster you're debt-free.

The formula

N=−ln(1−rBM)ln(1+r)
This gives the number of months to clear the card. Your payment M must be larger than the monthly interest (r × B) or the balance never falls and N has no solution.
N
— Months to pay off
B
— Outstanding card balance
r
— Monthly rate (APR ÷ 12, decimal)
M
— Fixed monthly payment

KalkWise simulates each month until the balance reaches zero, which also handles the final partial payment exactly.

  • Making a realistic debt-payoff plan
  • Seeing the cost of paying only the minimum
  • Comparing payoff speed at different payment levels
  • Motivating faster repayment of high-interest debt

Limitations & assumptions

  • Assumes a fixed APR and fixed monthly payment.
  • Does not model promotional 0% periods or balance-transfer fees.

Frequently asked questions

Minimum payments are usually 1–2% of the balance plus interest, so almost all goes to interest. $5,000 at 22% APR with $100/month minimum takes 79 months and costs $2,889 in interest. Paying $200/month cuts that to 31 months and $1,111 in interest — a saving of $1,778.
