Debt Payoff Calculator

See what an extra monthly payment really does. Enter the balance, the rate, what you pay now, and any extra amount — and compare how long the debt takes to clear, and how much interest you pay, with and without the extra payment.

No live data. Every rate, price, and percentage on this page is entered by you. Nothing is fetched from a bank, a market, or a government source, and no figure here is presented as a live or official rate.

What you still owe on the loan or card balance.

The yearly rate on the balance. Enter the rate your lender charges — no bank rate is used.

What you pay each month now, without any extra payment.

Any extra amount you would add each month. Enter 0, or leave blank, for no extra payment.

How it works

  1. Enter the balance you owe, the annual interest rate, and the monthly payment you make now.
  2. Add an extra monthly payment to see the difference. The extra amount goes straight to reducing the balance, because the month's interest is charged first.
  3. You see the payoff time and total interest with the extra payment, and the same figures without it, so the saving is plain to see.

The balance is reduced month by month, using the same reducing-balance approach as the EMI / Loan Calculator. If the payment does not even cover the month's interest, the balance would never fall, and a clear error is shown instead of a result.

Formula

Monthly interest = Balance × (Annual rate ÷ 12)

Balance reduction each month = Monthly payment − Monthly interest

The balance is worked out month by month until it reaches zero. Interest saved = Total interest without the extra payment − Total interest with the extra payment.

Worked example

Example: A balance of Rs 500,000 at 20% a year, paying Rs 15,000 a month, takes 50 months and costs Rs 235,909.43 in interest. Adding Rs 5,000 a month extra (Rs 20,000 in total) clears it in 33 months, with Rs 152,210.26 in interest — saving Rs 83,699.17 and 17 months.

Frequently asked questions

How does paying extra each month help?

Each month's interest is charged first, and the rest of your payment reduces the balance. An extra payment goes straight to the balance, so later months charge interest on a smaller balance, and the debt ends sooner and costs less.

What happens if my payment does not cover the interest?

The balance would grow instead of falling, and the debt would never clear. The calculator shows a clear error in that case, so you can raise the payment or the extra payment.

Why is the interest saving so large?

Because interest compounds on the balance. Cutting the balance early removes interest from every remaining month, so a small extra payment each month can save many times its own size in interest over the life of the loan.

Should I pay extra on the highest-rate debt first?

Usually, yes: extra payments save the most on the highest-rate balance. This calculator works out one balance at a time, so run it separately for each debt and compare.

Does this include fees or penalties?

No. Fees, late charges, and any early-settlement penalty are not included. Check your loan agreement, because a penalty could reduce or remove the saving.
