Home Loan Prepayment: Reduce the EMI or the Tenure?

A bonus, a maturing FD or an inheritance lands, and the home loan is the obvious place to put it. The bank then asks a question most borrowers have never thought about: do you want to reduce the EMI or the tenure? The lump sum is the same either way, but the interest you save is not. This guide works through both options with the same function that powers our prepay-or-invest calculator, then explains what the Reserve Bank’s 2025 Directions say about prepayment charges.

The example loan

• Outstanding principal: ₹30,00,000
• Interest rate: 9% per annum (floating)
• Remaining tenure: 180 months (15 years)
• Current EMI: ₹30,428.00
• Interest still to be paid if nothing changes: ₹24,77,040.00
• Lump sum available: ₹5,00,000

After the prepayment the balance is ₹25,00,000. Now the bank re-works the loan in one of two ways.

Option 1: keep the EMI, shorten the tenure

The EMI stays ₹30,428.00. Because the balance is smaller, more of each EMI is principal, and the loan closes early.

• New tenure: 129 months instead of 180, so 51 months (about 4.3 years) are cut
• Interest on the shortened loan: ₹13,99,843.67
• Interest saved: ₹10,77,196.33

Option 2: keep the tenure, lower the EMI

The loan still runs for 180 months, but on ₹25,00,000.

• New EMI: ₹25,356.66, which is ₹5,071.34 less every month
• Interest over the 180 months: ₹20,64,198.80
• Interest saved: ₹4,12,841.20

Side by side

The same ₹5,00,000 saves ₹6,64,355.13 more when you keep the EMI. The reason is simple: in option 1 you keep paying at the old pace, so the balance falls faster and there is less of it to charge interest on in every later month. In option 2 you take the benefit now, as a lower EMI, and the bank keeps the balance (and its interest) around for the full 15 years.

That does not make option 2 wrong. The ₹5,071.34 a month it frees is real money. If the lower EMI stops you from missing payments, lets you clear a costlier personal-loan or credit-card balance, or funds an SIP that you would otherwise skip, it can be the better choice for you. The point is to choose with the numbers in front of you rather than by default.

When prepaying is not the best use of the money

Prepaying a 9% loan is equivalent to earning 9% risk-free, after tax, with no lock-in. That is a good deal, but it is not automatically the best one. Our calculator compares the prepay option (keep the EMI, then invest the EMIs you no longer pay) with simply investing the lump sum, measured on the original loan-end date so the two are fair:

Below the loan rate, prepaying wins; above it, investing wins on paper. But the loan’s 9% is certain, while an investment return is an assumption that can be wrong for years at a time. Before choosing “invest” because a spreadsheet says 12%, ask whether you would actually hold the investment for the full 15 years, whether the return is after tax and costs, and whether the lump sum would stay invested or get spent. Many households split: part prepayment, part investment, and an emergency fund kept aside first.

Prepayment charges: the RBI Directions of 2025

The Reserve Bank of India (Pre-payment Charges on Loans) Directions, 2025 (dated 2 July 2025) apply to all loans and advances sanctioned or renewed on or after 1 January 2026, by all commercial banks (excluding payments banks), co-operative banks, NBFCs and All India Financial Institutions. For a home loan, the points that matter are:

• Floating-rate loan to an individual for a non-business purpose, with or without co-borrowers: no prepayment charge at all. This covers the ordinary home loan.
• The rule applies whether you prepay in part or in full, whatever the source of the money, and with no minimum lock-in period.
• For a dual or special-rate loan (fixed for some years, then floating), what counts is whether the loan is on a floating rate at the time of prepayment.
• Fixed-rate loans are outside this ban: any charge is as per the lender’s approved policy, and for a term loan it must be based on the amount being prepaid.
• Whatever applies to your loan must be disclosed in the sanction letter, the loan agreement and the Key Facts Statement. A charge that was not disclosed there cannot be levied, and a lender cannot reinstate a charge it had earlier waived.
• If the prepayment happens at the lender’s instance, no charge applies.

For loans sanctioned before 1 January 2026, the earlier circulars listed in the Directions’ annex governed; most floating-rate home loans to individuals were already free of foreclosure charges under them, but check your agreement and ask the bank for the current position in writing.

Prepayment versus a balance transfer

A lump sum is not the only way to cut interest. If another lender offers a materially lower rate, transferring the loan can save more than a one-time prepayment, and the two can be combined. Run the numbers with the EMI calculator: enter the outstanding balance, the remaining tenure and the new rate, and compare total interest with your current schedule. Then subtract the transfer costs (processing fee, legal and valuation charges, stamp duty on the new mortgage where applicable). A transfer pays off when a long tenure remains and the rate gap saves more interest than the transfer costs (processing fee, legal and valuation charges, stamp duty); work out both figures with the EMI calculator before deciding. Late in the loan, when little interest is left, neither a transfer nor a prepayment moves the needle much. Whatever you choose, keep the EMI the same after a transfer if you can afford it: a lower rate with the old EMI shortens the tenure just like a prepayment does.

How to do it well

1. Keep an emergency fund first. Six months of expenses, including the EMI, in a liquid account. A prepayment cannot be undone.
2. Prepay early rather than late. Interest is front-loaded; the same ₹5 lakh paid in year 2 of a 20-year loan saves far more than in year 15. Run the calculator with your actual remaining tenure.
3. Tell the bank which option you want. Most banks default to reducing the tenure; some default to reducing the EMI. Get it in writing with the revised schedule.
4. Check the statement after the prepayment. Confirm the new balance, the new tenure or EMI, and that no charge was deducted.
5. Repeat with small amounts if you can. Several banks allow part-prepayments throughout the year; even one extra EMI a year on a long loan removes years from the tenure. Test it in the calculator.

Frequently asked questions

Is it better to reduce the EMI or the tenure? Reducing the tenure saves more interest, in the example ₹10,77,196.33 against ₹4,12,841.20. Reduce the EMI only if you need the monthly room, for example to clear costlier debt.

Can the bank charge me for prepaying my home loan? Not if it is a floating-rate loan taken by an individual for a non-business purpose and sanctioned or renewed on or after 1 January 2026 (RBI Directions, 2025). For fixed-rate loans, only a charge disclosed in your sanction letter, agreement and Key Facts Statement can be levied.

Does the tax deduction on home-loan interest change the answer? It lowers the effective cost of the loan for those who claim it, which narrows the gap in favour of investing. The calculator does not model tax; adjust the loan rate downward yourself if you claim the deduction.

Should I prepay a loan that is nearly over? The interest left in the last couple of years is small, so the saving is small too. Compare the interest saved with what the money could earn elsewhere.
