Credit card payoff calculator

Estimate months to credit-card payoff, total interest, or the payment needed to hit a target payoff month.

What this calculator covers

Use this credit card payoff calculator to see how a fixed monthly payment changes the payoff month and total interest cost on a revolving balance.

You can also flip the problem around and solve for the payment required to hit a target payoff month, which is useful when you are working backward from a debt-free deadline.

The model uses a simplified monthly rate and assumes no new spending or fees, so it works best as a payoff-planning baseline rather than a replica of card servicing statements.

Frequently asked questions

What happens if my payment is too low to cover the monthly interest?
The calculator warns you when the planned payment does not exceed the first month's interest charge. Under that condition, the balance never starts falling and no payoff month can be shown.
Can I find out what payment I need to be debt-free by a specific month?
Yes. Switch the mode to solve for payment from target months, enter the month count you want, and the calculator returns the monthly payment required to amortize the balance in that time.
Why does the result differ from my actual card statement?
Card issuers typically use daily average-balance methods, not a simplified monthly rate. This tool is useful for planning, but your lender's statement will reflect actual billing rules.
Does the calculator account for new purchases during payoff?
No. The model holds the starting balance fixed and assumes no new charges, fees, or rate changes. Adding spending after the plan starts will extend the actual payoff horizon.

Primary result

59 months

$8,000.00 at 21.99% takes about 59 months to clear at $225.00 per month, with $5,063.09 in interest.

Monthly payment
$225.00
First month's interest
$146.60
Months to payoff
59 months
Total interest
$5,063.09
Total paid
$13,063.09

Step-by-step solution

  1. 1.The fixed payment plan uses $225.00 per month.
  2. 2.Each month adds interest at the simplified monthly periodic rate before the fixed payment is applied to the statement balance.
  3. 3.Repeat that payoff cycle until the balance reaches zero, which produces about 59 months to payoff and $5,063.09 of interest.

Walkthrough

Visual walkthrough

A fixed credit-card payoff plan is a month-by-month loop of interest accrual and payment reduction.

  1. 01

    Set the monthly payment plan

    The entered payment becomes the recurring monthly amount in the payoff simulation.

    $225.00 per month

  2. 02

    Add monthly interest

    The APR is simplified into a monthly periodic rate and applied to the remaining balance each cycle.

    $146.60 first interest charge

  3. 03

    Track the payoff horizon

    Repeating the payment-and-interest cycle until the balance hits zero yields the payoff month and total interest cost.
