Extra payment calculator
The answer
Adding $50.00 a month to a $200.00 payment on a $6,000.00 balance at 22.99% APR gets you there 1 yr 1 mo sooner, around Jul 2029, saving $898.58 in interest.
- Interest saved
- $898.58
- Without the extra
- 3 yr 10 mo · $3,011.78
An estimate from the inputs shown, not a promise of a particular date. How we calculate this.
The answer above is the same payoff engine run with the extra and again without it. The difference between those runs is the whole answer.
Assumptions
- Interest accrues once a month, before that month's payment.
- The APR stays at 22.99% for the whole term.
- No new spending, fees, penalty rate or promotional rate.
- You pay the payment plus the extra in full, on time, every month.

Why a small extra does more than it looks like it should
In this model everything above the month's interest reduces the balance, and balance you have removed stops accruing interest for the entire remaining term. The saving compounds against the length of the plan, which is why the effect is largest on long, high-rate balances and slight on brief balances.
On a real card, an amount paid above your minimum is allocated to your highest-rate balance ahead of the others under federal rules, and the minimum itself is allocated however your issuer chooses. With a single rate and no fees those come to the same thing; with a cash advance or a promotional transfer sitting on the same card, they do not.
It also shortens the term, and a shorter term is fewer months of interest charges at all.
Questions about this calculator
Does this model a lump-sum payment?
No. It assumes the same extra amount every month for the whole term. A lump sum lowers the balance once; to see its effect, reduce the balance by that amount and compare the dates.
What does the schedule's last column show?
The balance each month without the extra, from a separate run of the same engine on the same card. The gap between the columns is what the extra is doing, month by month.
What if my monthly payment does not cover the interest?
Then the balance cannot fall without the extra, and the calculator says so. It still shows whether the payment with the extra clears the balance, and when.
Should I pay extra or save the money?
The arithmetic cannot decide that. It shows what the extra does to this debt; it does not weigh an emergency fund, a retirement match or your other debts. A non-profit credit counsellor can help with that decision.

Reviewed 2026-09-19. Every figure on this page is produced by the same payoff engine the Dang!

The dates printed here were computed from a plan starting October 2026; the calculator re-anchors to the current month in your browser, so a date you read with JavaScript disabled is the one for that starting month rather than for today.
