# Prepay Home Loan or Invest? How to Decide, with Numbers > Prepay your home loan or invest the money? A fair side-by-side with real numbers, the tax angle in both regimes, and a checklist before you prepay. Source: https://trykosh.com/learn/home-loan-prepay-or-invest Guide - Loans # Should you prepay your home loan or invest? Prepaying a home loan earns exactly your loan's interest rate, with no risk. Investing might earn more, or less. The answer depends on that gap, on tax, and on what else your money needs to do first. Updated 25 October 20266 min readBy the Kosh team On this page[The core idea](#core-idea)[What prepaying actually does](#what-prepaying-does)[A fair comparison over the same 15 years](#fair-comparison)[The tax angle](#tax)[Before you prepay: a checklist](#checklist)[Middle paths that work](#middle-paths)[FAQs](#faq) ## The core idea Every rupee you prepay stops being charged interest for the rest of the loan. So prepaying is like an investment that earns **your loan rate, guaranteed and tax-free**. On an 8.5% loan, prepaying earns 8.5% a year. Investing the same money only wins if it earns more than that **after tax and after accounting for risk**. An equity fund might average more over 15 years, but it won't do so every year, and the gains are taxed. A fixed deposit at 7% taxed at your slab can't beat an 8.5% loan at all. The real question is whether the expected extra return from investing is worth the uncertainty. ## What prepaying actually does Take a INR 40 lakh loan at 8.5% for 15 years. The EMI is **INR 39,390** and total interest over the loan is **INR 30,90,125**. Now prepay INR 5 lakh in month 6. The [loan prepayment calculator](/tools/loan-prepayment-calculator) shows two ways the bank can apply it: INR 5 lakh prepaid in month 6 on INR 40 lakh at 8.5% for 15 years Option EMI Loan ends Interest saved No prepayment INR 39,390 15 years INR 0 Prepay, keep EMI, cut tenure INR 39,390 11 years 11 months INR 9,94,307 Prepay, keep tenure, cut EMI INR 34,381 15 years INR 3,71,434 Cutting the tenure saves almost three times as much interest, because the whole prepayment keeps working for the full remaining term. Ask your bank to apply prepayments this way unless you specifically need a lower EMI. Under RBI rules, banks can't charge a prepayment penalty on floating-rate home loans taken by individuals. ## A fair comparison over the same 15 years "Interest saved" and "investment gains" aren't directly comparable, because prepaying pays you back later: the loan ends 37 months early, and the EMI you no longer pay can then be invested. So compare where you stand at the end of the original 15 years: - **Invest:** put INR 5 lakh into equity in month 6 and leave it for the remaining 174 months. - **Prepay:** prepay INR 5 lakh in month 6, then invest the INR 39,390 EMI each month for the 37 months after the loan closes. Value at the end of year 15, after long-term capital gains tax (returns are assumptions) Assumed equity return Invest INR 5 lakh Prepay, then invest the freed EMI Better option 8% a year INR 14,63,540 INR 16,47,905 Prepay 10% a year INR 19,24,596 INR 16,96,050 Invest 12% a year INR 25,38,268 INR 17,46,196 Invest The break-even is an equity return of about **9% a year before tax**. Above it, investing ends ahead; below it, prepaying wins. Long-run equity returns have often been above 9%, which is why investing usually wins on paper. But that's an average over long periods, not a promise for your 15 years, and the prepay column is the same in every row: it doesn't depend on markets at all. **How these figures were worked out** Equity values are worked out with monthly compounding, and tax as 12.5% on long-term gains above INR 1.25 lakh plus cess, assuming everything is redeemed at the end. They're illustrations, not forecasts. ## The tax angle Tax can tilt the answer either way, and it depends on your regime: - **New regime:** no deduction for interest or principal on a self-occupied home. Prepaying costs you no tax benefit, so its return is the full loan rate. - **Old regime, interest above INR 2 lakh:** section 24(b) allows up to INR 2 lakh of interest a year on a self-occupied home. On the loan above, year-one interest is about INR 3.35 lakh and stays above INR 2 lakh for years, so prepaying mostly removes interest that wasn't deductible anyway. - **Old regime, interest below INR 2 lakh:** here every rupee of interest saves tax at your slab. At 30% plus cess, an 8.5% loan really costs about 5.85%, which makes investing more attractive. - **Principal** counts toward the INR 1.5 lakh 80C limit in the old regime, but most salaried people fill that with EPF already. Check the regime question first: with a INR 20 lakh salary, INR 3 lakh of interest and INR 1.2 lakh of principal, the [home loan tax benefit calculator](/tools/home-loan-tax-benefit-calculator) shows the loan saves INR 93,600 in the old regime, yet the new regime still comes out lower (INR 1,92,400 against INR 3,04,200). For many borrowers the deduction they're trying to protect isn't even being used. ## Before you prepay: a checklist 1. **Emergency fund in place?** Money prepaid into a loan is very hard to get back. Keep 6 or more months of expenses and EMIs liquid first. See [how much emergency fund you need](/learn/how-much-emergency-fund-do-i-need). 2. **Costlier debt cleared?** Credit cards, personal loans and car loans almost always cost more than a home loan. Pay those first. 3. **Adequate term and health cover?** If you die, term insurance clears the loan; prepaying doesn't protect your family the same way. 4. **Big goals in the next 5 years?** A child's admission or a down payment needs cash on a date. Don't lock it into the house. 5. **Any prepayment charge?** Usually none on floating-rate loans to individuals, but fixed-rate loans can charge one. Check your sanction letter. 6. **Could a cheaper rate do more?** If your rate is well above what new borrowers get, a [balance transfer](/tools/home-loan-balance-transfer-calculator) or simply asking your bank to reprice may save more than a prepayment. ## Middle paths that work - **Split it.** Prepay half, invest half. You get a guaranteed return on part and growth potential on the rest, and you're never entirely wrong. - **Raise the EMI with your salary.** Increasing the EMI by 5% a year shortens the loan sharply without needing lump sums. - **Prepay when rates rise.** On a floating-rate loan, a rate increase raises the guaranteed return on prepaying. That's a natural time to shift the balance. - **Prepay early, not late.** Interest is front-loaded. In the last few years of a loan, most of the EMI is principal and prepaying saves little. ### What about PPF or an FD instead? Against safe options the maths is simpler. An FD at 7% taxed at 30% plus cess earns under 5% after tax, well below an 8.5% loan. PPF's 7.1% is tax-free but still below 8.5%. So if your alternative to prepaying is a safe deposit, prepaying usually wins, unless you need the 80C deduction in the old regime and have no other way to fill it, or you need the money to stay accessible.

It explains options; it doesn't recommend specific funds. ## Frequently asked questions Is it better to prepay a home loan or invest? Prepaying earns your loan's interest rate with no risk; investing wins only if it earns more after tax. In our example, an 8.5% loan breaks even with an equity return of about 9% a year before tax. Many people split the money between the two. Should I reduce EMI or tenure after prepaying my home loan? Reducing tenure saves much more interest. On a INR 40 lakh loan at 8.5% for 15 years, a INR 5 lakh prepayment saves about INR 9.94 lakh by cutting tenure, against about INR 3.71 lakh by cutting the EMI. Is there a penalty for prepaying a home loan? Under RBI rules, banks and housing finance companies can't charge prepayment penalties on floating-rate home loans to individuals. Fixed-rate loans may carry a charge, so check your loan agreement. Do I lose the tax benefit if I prepay my home loan? Only in the old regime, and only if your interest falls below the INR 2 lakh limit under section 24(b). In the new regime there's no deduction for a self-occupied home, so prepaying costs nothing in tax. When should I not prepay my home loan? Hold off if you don't have an emergency fund, if you carry costlier debt like credit cards, if you lack adequate term or health insurance, or if you need the money for a goal within a few years. ## Sources - [Reserve Bank of India](https://www.rbi.org.in/) - [Income Tax Department](https://www.incometax.gov.in/) Written by the Kosh team and checked against the rules in force on 25 October 2026.
