Prepay a Loan: Reduce EMI or Tenure? Real Numbers on a ₹50 Lakh Loan

Open your home loan statement and look at two lines: principal outstanding, and EMIs left. A part payment always brings the first one down. What happens to the second depends on one question on the bank's prepayment form, or a toggle in the app if your bank bothers to show it: should this money reduce your EMI, or reduce your tenure?

Most people tick whatever the branch staff suggest, or leave it blank and let the bank's system decide. On a ₹50 lakh home loan, that one choice can decide whether the same ₹5 lakh saves you about ₹4.5 lakh of interest or about ₹13 lakh. The numbers for a home loan and a personal loan are below, along with what RBI lets lenders charge, whether the money would do better in a fund, and, at the end, how to actually file the request and check that the bank did what you asked.

What a prepayment does to the loan

Home loans and personal loans in India work on a reducing balance. Each month the bank charges interest only on the principal still outstanding, and the rest of your EMI goes towards cutting that principal.

In the early years the outstanding amount is big, so most of the EMI is interest. On a ₹50 lakh loan at 8.5% for 20 years, the EMI is ₹43,391. In the first year you pay ₹5.21 lakh in EMIs, and only about ₹99,500 of that reduces the loan. More on that split in how EMI is calculated.

A prepayment skips the interest part completely. Every rupee goes straight into principal, and lower principal means lower interest every month for the rest of the loan. That's why money prepaid early saves far more than the same money prepaid in the last few years.

Once the principal drops, the bank rebalances the loan. It can keep your EMI the same and finish sooner, or keep the end date and lower your EMI. That is the choice on the form.

The two boxes on the form

Reduce tenure. You keep paying the same EMI, and since less principal is left, the loan closes earlier. The saving is bigger, because the principal you knocked off stops attracting interest for all the remaining years.

Reduce EMI. The loan still ends on the original date, but the EMI is recalculated on the lower principal. You get some breathing room every month. The interest saving is smaller, because the loan runs just as long as before.

Banks differ here. Some cut the tenure by default, some reduce the EMI. If you don't say, you get whatever their system does.

The numbers on a ₹50 lakh home loan

Say you took ₹50 lakh at 8.5% for 20 years. (The best borrowers at big banks have been getting roughly 7.25–8%, but plenty of loans run at 8.5% or more.) The EMI is ₹43,391 and, with no prepayment, total interest over 20 years is ₹54.14 lakh. More than the loan itself.

After 36 EMIs, ₹46,74,300 is outstanding. Now you prepay ₹5 lakh:

Same ₹5 lakh. Reducing the EMI saves about ₹4.47 lakh and leaves ₹4,641 a month extra in hand. Reducing the tenure saves about ₹13.2 lakh and the loan closes 41 EMIs early. Three times the saving.

You can check this on the home loan EMI calculator: ₹46,74,300 for 17 years at 8.5% gives back the old EMI, and ₹41,74,300 for 17 years gives the reduced one. For the tenure side, put ₹41,74,300 at 8.5% for 13.5 years into the EMI calculator. The EMI comes out at ₹43,400, just above what you pay, which is why it takes about 162 more EMIs to finish.

Can't decide? Choose "reduce EMI" so your fixed commitment is lower, then keep paying the old EMI amount, sending the difference as regular part payments. Keep it up and you get close to the reduce-tenure saving. If money gets tight one year, stop the extra. Check first that your bank accepts small part payments without fuss.

₹1 lakh every year: what the habit does

You don't need ₹5 lakh in one go. Say you prepay ₹1 lakh at the end of every year on the same loan, out of your bonus, and keep the EMI unchanged each time.

You end up prepaying 13 times, ₹13 lakh in all, and the loan closes after 168 EMIs. That's 14 years instead of 20. Total interest drops from ₹54.14 lakh to about ₹35.58 lakh, a saving of about ₹18.55 lakh. Six years without an EMI is a big deal when it lines up with your child's college fees.

The habit matters more than the size. Even ₹25,000 a year, started early, cuts months off the loan. Started in year 17, it barely moves anything.

Prepaying a personal loan

Personal loans cost more. Big banks advertise starting rates around 10%, but many people pay 13–16% or more depending on credit score and employer. Take ₹5 lakh at 14% for 5 years. The personal loan EMI calculator shows an EMI of ₹11,634 and total interest of ₹1,98,048. After 12 EMIs, ₹4,25,746 is outstanding, and you prepay ₹1 lakh.

Most personal loans and car loans are on a fixed rate, so the lender can charge for prepayment. Many banks take around 2–4% (of the amount prepaid or of the outstanding, depending on the bank) plus GST, some waive it after a year or so, and some allow a part payment only once a year up to a cap. At 14%, a year into the loan, the saving is still well worth it. Late in the loan the maths flips: a 4% charge on a loan with a year left can wipe out most of what you'd save. Read the exact terms in your sanction letter or Key Facts Statement first.

Prepayment charges: what RBI allows

For floating-rate loans taken by individuals for non-business purposes, which covers most home loans, there are no prepayment or foreclosure charges. That has been the rule for floating-rate home loans and term loans to individuals since 2012–2014, and RBI's Pre-payment Charges on Loans Directions, 2025 tightened it for loans sanctioned or renewed from 1 January 2026:

• It covers banks, co-operative banks and NBFCs, housing finance companies included.
• Part or full, from your savings or from another bank's loan when you switch: no charge, and no minimum lock-in.
• Floating-rate business loans to individuals and small businesses are covered too, though small finance banks, RRBs and some others can charge on loans above ₹50 lakh.
• For other loans, like fixed-rate ones, charges follow the lender's policy but must be shown in the sanction letter, agreement and Key Facts Statement. An undisclosed charge can't be levied, and a fee waived earlier can't be charged later.

The Key Facts Statement has been compulsory for retail loans since October 2024 under RBI's KFS circular. If your bank tries to charge you for part-prepaying a floating-rate home loan, ask which clause allows it, in writing.

One catch: on loans that are "fixed for a few years, then floating", what counts is whether the rate is floating on the day you prepay.

When a rate rise quietly stretches your loan

RBI raised the repo rate by 0.25% to 5.50% on 7 October 2026. Most new floating-rate home loans are linked to the repo rate, so they move up at the next reset. And many banks don't raise your EMI. They stretch the tenure instead, and you only notice when you read the statement.

Take the same loan after 3 years: ₹46.74 lakh left, 17 years to go. If the rate goes from 8.5% to 8.75%, the EMI would need to rise by ₹710, to ₹44,102, to finish on time. If the bank keeps the EMI at ₹43,391, the remaining tenure goes from 204 months to about 212. Eight more EMIs from a quarter-percent rise.

Under RBI's 2023 circular on floating-rate resets, the bank must tell you, let you choose a higher EMI, a longer tenure or a mix, and let you prepay any time. It also has to send a quarterly statement showing the EMIs left, so check it after every rate change. A prepayment with "reduce tenure" pulls those months back. More on this in how a repo rate change moves your EMI.

Prepay or invest the money instead

Prepaying a loan at 8.5% is a guaranteed 8.5% return with zero risk. An equity fund might give more over 15–20 years, but not for sure.

Take the same ₹5 lakh, with 17 years left on the loan:

• Invest it in an equity fund. At an assumed 12% a year it grows to ₹34.33 lakh in 17 years on the lumpsum calculator. At 10%, ₹25.27 lakh. At 8.5%, ₹20.01 lakh.
• Prepay it with reduced tenure, then put the freed EMI (₹43,391 a month for the last 41 months) into the same fund till the original end date. That builds about ₹22.22 lakh at 12%, ₹21.51 lakh at 10% and ₹20.98 lakh at 8.5%.

At 12%, investing wins by about ₹12 lakh before tax. Long-term capital gains tax (12.5% above ₹1.25 lakh, plus cess) takes about ₹3.65 lakh of that lumpsum gain, so investing is still clearly ahead, if 12% actually shows up. At 10% the gap shrinks to under ₹4 lakh before tax, for 17 years of market risk. At 8.5%, prepaying wins.

What decides it for most people:

• Compare after tax. An FD at 6–6.5% loses a chunk to tax in higher slabs. For spare money that would otherwise sit in an FD, prepaying an 8.5% loan is the better deal.
• Costliest loan first. A 14% personal loan, or credit card dues that cost far more, eat up more than most investments can reliably earn. The order is credit card, then personal loan, then car loan, then home loan.
• Split it. Plenty of people put half the bonus into prepayment and half into a SIP. Some guaranteed saving, some growth.

Whichever way you lean, prepay with fresh money: a bonus, a matured FD, an arrears payout. Selling a long-term fund in a falling market just to prepay turns a temporary fall into a real loss.

Does prepaying waste the ₹2 lakh deduction?

In the new regime, which most salaried people now use, a self-occupied home loan gives no deduction at all. Every rupee of interest saved is a full saving.

In the old regime, you can claim up to ₹2 lakh a year of interest on a self-occupied house (old section 24(b)), and principal repaid, prepayments included, counts towards the ₹1.5 lakh limit of section 123 (old 80C). People worry that prepaying "wastes" the deduction. On our loan, year-4 interest is ₹3.92 lakh. After the ₹5 lakh prepayment it's ₹3.48 lakh, still above the ₹2 lakh cap, and it stays above ₹2 lakh till about year 11. You claim the same ₹2 lakh either way, and the interest above the cap gets no tax benefit anyway.

The deduction matters only once yearly interest falls below ₹2 lakh, and the 80C limit is usually full already with PF and the regular EMI's principal. Run both regimes on the income tax calculator if you're unsure.

Tenure, EMI, or not yet

Reduce tenure if the EMI is comfortable (say under 35–40% of take-home), income is steady, and you'd like to be loan-free before big expenses like children's higher education or retirement. For most salaried people in their 30s and 40s, this is the default.

Reduce EMI if the EMI is squeezing your monthly budget, yours is the only income at home, your job feels shaky, or a rate reset just pushed your EMI up. A lower EMI also helps if you plan another loan soon, because banks check how much of your income already goes into EMIs.

Hold off for now if you don't yet have a few months of expenses sitting in an FD or savings account that you won't touch. Money sent to the bank as a prepayment doesn't come back, and if a hospital bill lands next month you end up borrowing at 14% to cover it. Wait too if you're carrying credit card dues or a costlier loan, or if the loan is in its last few years. Late in the loan the interest part is small, so prepaying saves little. On long loans the case is stronger (see 20 vs 30 year home loans).

Sending the money, and making sure the tenure actually drops

Start with the latest loan statement or the loan section of your bank's app. Note three things: the principal outstanding today, the number of EMIs left, and whether the rate is floating on this date. If the loan is on a fixed rate, find the prepayment charge in the Key Facts Statement before you pay anything, so there's no surprise later.

Then the request. Many banks take part payments through net banking or the app. Others want a cheque or NEFT along with a signed request at the branch that services your loan. Some apps show the EMI-or-tenure choice on the payment screen, many don't, and then the bank's default applies. So put your choice in writing either way. A short letter, or an email from the email ID registered with the loan, is enough: loan account number, amount, date of payment, and one plain line like "Please apply this amount to principal and reduce the tenure, keeping the EMI unchanged." Ask for an acknowledgement and keep it.

When the revised repayment schedule comes, check three things. First, the principal should have dropped by the full amount on the day you paid. If the money shows up as "advance EMI", or sits as an unadjusted credit, it isn't saving you any interest yet, so take it up straight away. Second, the EMI should be exactly what it was. Third, the EMIs left should have fallen. In the ₹50 lakh example, ₹5 lakh prepaid after 3 years should pull the last EMI in by 41 months, to about 16 years 7 months from the start. If you chose the lower EMI instead, look for ₹38,750 and the old end date. The next quarterly statement should show the same thing.

If the bank has done the opposite of what you asked, write back quoting your acknowledgement and ask for it to be corrected. If there's no proper reply within 30 days, you can complain to the RBI Ombudsman at cms.rbi.org.in.

Keep every acknowledgement and revised schedule in the same file as your sanction letter. If you ticked "reduce tenure" a few times, the loan will close years before the date on that letter, and when it does, you want the closure letter and your original property papers back without a chase. RBI's rules give the lender 30 days from the final payment to return them.
