How to Pay Off a Loan Faster With Extra Payments

Published 1 November 2026 by Kloora Tools

Quick answer: paying a fixed extra amount each month goes straight to the principal, so you pay interest on a smaller balance and finish earlier. On a 1,000,000 loan at 12 percent over 5 years, adding 5,000 a month finishes the loan in 46 months instead of 60 and saves about 82,000 in interest.

Does paying extra on a loan really save interest?

Yes. Interest is charged on the outstanding balance each month. An extra payment lowers the balance sooner, so the next month's interest is smaller. The saving compounds every month for the rest of the loan. The earlier you start, the larger the saving.

How much can you save? A worked example

Take a loan of 1,000,000 at 12 percent a year for 60 months. The monthly rate is 1 percent.

• Normal payment: 22,244 a month. Total paid 1,334,667. Interest 334,667.
• With 5,000 extra each month (27,244 total): the loan is cleared in 46 months. Total paid about 1,252,275. Interest about 252,275.

You pay 14 months less and keep about 82,000. The extra 5,000 a month adds 230,000 over 46 months, yet you still come out ahead because the interest saved is larger than the shorter term costs.

What are the best ways to pay a loan off early?

1. Fixed extra monthly amount. Easiest to plan and automatic.
2. Annual lump sum. Use a bonus or tax refund once a year.
3. Round up the payment. Move 22,244 to 25,000 and keep it there.
4. Pay half monthly. Where the lender allows it, it can add one extra payment per year.
5. Refinance to a lower rate if the new fees are smaller than the interest saved.

Will the bank charge a prepayment penalty?

Many lenders charge a fee for early settlement, or only allow extra payments after a fixed period. Ask for the written terms. A common form is a percentage of the amount prepaid. If the fee is 1 percent and you prepay 100,000, you pay 1,000. Compare that with the interest saved before you decide. Also confirm that extra payments reduce the principal, and are not simply held as advance instalments.

Should you prepay or invest the money?

Compare the loan rate with what you can reliably earn. If the loan costs 12 percent and a safe savings option pays less, prepaying is a guaranteed return equal to your interest rate. If your loan is cheap and you can earn more after tax and risk, investing may win. Keep an emergency fund first. Never prepay with money you will need next month.

Which loans should you pay off first?

Start with the most expensive: credit cards and short-term personal loans. A card at 36 percent or more is far costlier than a home loan at a lower rate. The Credit Card Payoff Calculator shows how long a balance lasts at a given payment.

How do you use the calculator to plan?

1. Enter the loan amount, annual rate and term in the Loan Calculator.
2. Note the monthly payment and total interest.
3. Add your planned extra amount to the payment and compare the new months and interest in a spreadsheet or by re-running with a shorter term.
4. Choose an amount you can keep for the full period.
