Home Loan Prepayment: How Much Interest You Save with Extra EMIs
Published 10 October 2026 · 5 min read · Clean EMI Editorial
Prepayment is the most powerful and least used tool in home loan planning. Because interest is charged on the outstanding balance, every rupee you pay early cuts interest for every month that remains.
Part of the Home Loan guide series.
The example
Loan: ₹50 lakh at an illustrative 8.5% for 20 years. EMI is about ₹43,391 and total interest about ₹54.1 lakh. Now add ₹5,000 extra every month. The loan ends in about 15 years 7 months, and total interest falls to about ₹40.2 lakh: a saving of roughly ₹13.9 lakh and more than four years of EMIs.
Why early prepayment works best
In the first years most of each EMI is interest. Extra payments in those years remove principal that would otherwise have accrued interest for many years. Prepaying in year 15 saves far less.
Reduce tenure or reduce EMI?
Reducing the tenure saves the most interest. Reducing the EMI gives monthly relief. If your budget is tight, choose the EMI cut; otherwise choose the shorter tenure.
Charges
Under RBI rules, banks cannot levy foreclosure or prepayment charges on floating-rate loans to individuals. Fixed-rate loans can carry charges, so check your sanction letter.
Prepay or invest?
Prepayment gives a guaranteed return equal to your loan rate, with no market risk. If your tax deduction on interest applies (old regime), the effective cost is a little lower. Keep your emergency fund separate and read how to choose the right EMI and tenure.
If the rate itself is high
Moving to a lower rate may beat prepaying. See the balance transfer page, and test amounts on the home loan calculator. For one PSU lender’s rules, see Bank of Baroda.
Frequently Asked Questions
How much can I prepay in a year?
There is typically no limit on floating-rate loans to individuals, though banks may set a minimum part-payment amount. Check with your branch.
Is it better to make one big prepayment or many small ones?
The earlier the money reaches the loan, the more interest it saves. Small monthly extras work well if you do not have a lump sum.
Will prepayment reduce my EMI automatically?
Usually the tenure reduces unless you ask the bank to reduce the EMI. Confirm which option you want in writing.
Are there taxes on prepayment?
There is no tax on prepaying. Interest deductions fall as your interest falls, so ask a tax professional how it affects your return.
