Prepaying Rs 10 Lakh on a Rs 1 Crore Bengaluru Home Loan: Shorter Tenure or Lower EMI?

Two years into a Rs 1 crore home loan on a flat in Electronic City, a software engineer receives a Rs 10 lakh bonus and a choice from the lender's app: reduce the EMI or reduce the tenure. The screen does not say which saves more. The difference, on the numbers below, is roughly Rs 19.5 lakh of interest.

With the repo rate at 5.50 percent after RBI's October 2026 hike, more Bengaluru borrowers are looking at prepayment as a way to control interest costs. This guide runs the arithmetic on one illustrative loan and sets out what RBI's rules for housing finance companies say about prepayment charges.

The short answer. On an illustrative Rs 1 crore loan at 8.50 percent over 20 years, the EMI is Rs 86,782. A Rs 10 lakh prepayment after 24 EMIs saves about Rs 29.1 lakh of interest if you keep the EMI and cut the tenure by about 45 months, but only about Rs 9.6 lakh if you keep the tenure and cut the EMI to Rs 77,728. The trade-off: cutting tenure saves far more interest, while cutting the EMI frees about Rs 9,055 a month of cash flow. For floating-rate HFC loans, RBI's Directions say no prepayment charge applies.

What do RBI's rules say about prepayment charges?

Paragraph 163 of the Reserve Bank of India (Housing Finance Companies) Directions, 2025, shown as updated on October 1, 2026, deals with foreclosure and prepayment of housing loans. Paragraph 163(1) provides that no prepayment charge is levied on floating-rate housing loans, whatever the source of funds used to prepay.

Paragraph 163(2) covers fixed-rate loans. No charge applies when such a loan is prepaid from the borrower's own sources. The paragraph adds that funds borrowed from a bank, HFC, NBFC or financial institution are not own sources. Paragraphs 163(3) to 163(5) say that dual-rate or special-rate loans follow the fixed or floating norm that applies at the time of prepayment.

For a typical Bengaluru buyer with a floating-rate loan, the practical effect is simple: a bonus, an ESOP sale or a maturing deposit can go into the loan without a penalty. Our earlier piece on RBI's pre-payment charges directions for banks and other lenders covers the parallel rules beyond HFCs.

How much does a Rs 10 lakh prepayment save, and when?

The table uses one illustrative loan: Rs 1 crore at 8.50 percent over 240 months, with an EMI of Rs 86,782. It shows what a Rs 10 lakh prepayment does at different points in the loan, under the two choices a borrower typically weighs. The rate is an assumption, not a quote; your own figures will differ.

Two patterns are clear. First, the earlier the prepayment, the bigger the saving, because more of the loan's future interest is still ahead of you. Second, at every point, keeping the EMI and shortening the tenure saves roughly three times as much interest as keeping the tenure and lowering the EMI.

Why does cutting tenure save so much more?

When you keep the EMI at Rs 86,782 after a prepayment, every rupee of that EMI above the new, lower interest charge goes to principal. The loan shrinks faster each month, so the interest on the following month is smaller again. The effect compounds, which is why about 45 months disappear from the end of the loan in the first row.

When you keep the tenure and lower the EMI, the lender recalculates a smaller EMI over the same remaining months. You still pay interest for the full remaining period, just on a slightly lower balance. You save interest, but far less of it.

Our explainer on EMI math at a 5.50 percent repo for larger Bengaluru loans shows the same tenure effect from the other direction, when rates rise and tenure stretches.

When does cutting the EMI make more sense?

The table measures interest only. Cash flow matters too. Lowering the EMI by about Rs 9,055 a month gives a household breathing room if a second income is uncertain, if school fees are about to rise, or if the buyer wants to rebuild an emergency fund that the down payment drained. Over the remaining 216 months of the loan, a Rs 9,055 lower EMI adds up to about Rs 19.6 lakh of cash kept in hand, spread thinly across 18 years, against the larger interest saving that the shorter tenure delivers.

There is also a middle path. Some borrowers keep the EMI unchanged after a prepayment for as long as they comfortably can, knowing that they can ask the lender to reset the EMI later if circumstances change. Whether and how your lender allows that is a matter for your loan agreement, so ask before you assume it.

Rates matter as well. RBI's FAQ on resetting floating rates on EMI-based loans, updated as on October 1, 2025, lists prepayment, in part or in full, as one of the options a lender must offer when rates rise for a class of borrowers. A prepayment ahead of a possible rate increase reduces the balance on which any higher rate will apply.

Does prepaying reduce your tax deduction on interest?

For most Bengaluru borrowers at these loan sizes, not in the early years. The government's Memorandum explaining the Finance Bill, 2026 states that Section 22(2) of the Income-tax Act, 2025 caps the deduction for interest on a self-occupied property bought or built with borrowed capital at Rs 2 lakh a year.

On our illustrative loan, the outstanding balance after the Rs 10 lakh prepayment in year two is about Rs 85.8 lakh, and the interest paid over the following 12 EMIs works out to about Rs 7.2 lakh. That is still well above Rs 2 lakh, so the deduction you can claim on a self-occupied home does not shrink because of the prepayment. The interest you no longer pay was above the cap in any case. The picture changes only once annual interest falls toward Rs 2 lakh, which on these terms happens much later in the loan. If the flat is let out, or your tax position is unusual, ask your adviser how the rules apply to you.

How should a Bengaluru borrower plan a prepayment?

Start by confirming the type of loan. If you bought in a project such as Godrej Nurture in Electronic City with an HFC loan, the sanction letter and Key Fact Statement will say whether the rate is floating, fixed or dual. That decides which part of paragraph 163 applies.

Then check the lender's process. Ask how your lender accepts part prepayments, and make sure the confirmation states the new outstanding balance and either the new EMI or the new tenure. Keep that confirmation with your loan papers, together with the bank statement showing the payment.

1. Confirm from your sanction letter whether your loan is floating, fixed or dual rate.
2. For a floating-rate HFC loan, note that paragraph 163(1) bars a prepayment charge regardless of the source of funds.
3. For a fixed-rate loan, check whether the money is from your own sources, as paragraph 163(2) defines them.
4. Decide between cutting tenure and cutting EMI, using your own loan figures.
5. Keep an emergency fund in place before you prepay.
6. Ask the lender to confirm the new balance and the new EMI or tenure in writing.
7. Recheck the statement after the next EMI to confirm the prepayment was applied to principal.

Should you prepay or keep the money invested?

That depends on your own finances, and this article does not recommend one over the other. A prepayment gives a known saving at your loan rate, while money kept aside gives liquidity. A household with an adequate emergency fund and no higher-cost debt may find prepayment attractive; one without a cushion may prefer to hold cash. Whatever you choose, make the choice on your own figures rather than on the default option the lender's app shows first.

Frequently asked questions

Does an HFC charge a fee if I prepay a floating-rate home loan?

No. Paragraph 163(1) of RBI's Housing Finance Companies Directions, 2025, updated as on October 1, 2026, provides that no prepayment charge is levied on floating-rate housing loans, whatever the source of the funds used. Fixed-rate loans are treated differently, so check which kind of loan you hold before you plan a lump sum.

Is it better to reduce tenure or reduce EMI after a prepayment?

On our illustrative Rs 1 crore loan at 8.50 percent, a Rs 10 lakh prepayment after 24 EMIs saves about Rs 29.1 lakh of interest if you keep the Rs 86,782 EMI and cut about 45 months, against about Rs 9.6 lakh if you keep the tenure and cut the EMI by Rs 9,055.

Does prepaying early save more than prepaying later?

Yes, on these numbers. The same Rs 10 lakh with the EMI kept unchanged saves about Rs 29.1 lakh after two years, about Rs 21.4 lakh after five years and about Rs 11.4 lakh after ten years, because there is less future interest left to remove as the loan matures.

Can I prepay a fixed-rate home loan without a charge?

Paragraph 163(2) of the HFC Directions says no charge applies when a fixed-rate loan is prepaid from the borrower's own sources, and it states that borrowing from a bank, HFC, NBFC or financial institution is not own sources. So refinancing a fixed-rate HFC loan through another lender may attract a charge under your agreement.
