How long does a fixed credit-card payment take to clear the balance?
A card payoff schedule charges monthly interest on the remaining balance, then applies the rest of the payment to principal. As principal falls, more of the same payment becomes available for principal reduction.
Interest first, then principal reduction
i = APR ÷ 100 ÷ 12Each month: Interest = Balance × i Balance = Balance − (Payment − Interest)Repeat until the balance reaches zero. If the payment is notlarger than the first month's interest, the balance never clears.A fixed payment until the card reaches zero
The default case repeats the monthly interest-and-principal calculation until the balance reaches zero, then totals elapsed months, interest and payments.

- Card balance
- $6,000.00
- APR
- 22%
- Monthly payment
- $250.00
Step-by-step calculation
- Monthly rate = 22 ÷ 100 ÷ 12 = 0.018333. First interest charge = 6,000 × monthly rate = 110.
- First principal reduction = payment 250 − interest 110 = 140. Apply the same process to each smaller balance.
- With no new spending and a capped final payment, payoff takes 32 months. Total paid = 7,979.048949, including 1,979.048949 interest.

Why increasing payment saves interest twice
A larger fixed payment reduces both payoff time and total interest. The first month’s interest is shown so the entered payment can be checked against the minimum needed to reduce principal.
The payment must exceed accrued interest
If payment is equal to or below accrued monthly interest, the balance never clears under a fixed-rate model. The page displays an explicit warning for that case.
- APR is fixed and converted to a monthly rate.
- The same payment is made monthly with no new purchases.
- Late fees, promotional rates and issuer minimum-payment rules are excluded.

Quick answers
Frequently asked questions
Why will my credit-card balance never clear at some payment amounts?
If the monthly payment is no larger than the interest charged, none of the payment reduces principal.
Does the calculator use daily credit-card interest?
No. It converts APR to a monthly rate and runs a monthly balance simulation.
Are new purchases and fees included?
No. The calculation assumes no additional spending, fees or rate changes.
