Prepaying your home loan makes more financial sense when your interest rate is above 9% and you're in the first half of your tenure — the guaranteed interest saving beats a conservative FD or debt fund on a risk-adjusted basis. Investing in a SIP wins over the long run if your equity returns exceed your loan rate, which the Nifty 50 TRI has historically done at ~13% CAGR over 20+ years. The right answer depends on your specific loan rate, tenure remaining, and risk appetite — use this calculator to see your personal numbers before deciding.

The best time to prepay is in the early years of your loan — ideally within the first 5–8 years. EMIs in this period are heavily weighted toward interest, so prepaying principal now eliminates years of compounding interest. Prepayment in the final 3–4 years of a loan has much lower impact because most of the interest has already been paid through your regular EMIs.

Prepayment reduces your outstanding principal, which reduces the interest component of your future EMIs — and a lower interest component means a smaller Section 24(b) deduction, currently capped at ₹2 lakh per year for self-occupied property. The principal repayment portion of your regular EMI remains eligible under Section 80C (up to ₹1.5 lakh), but a one-time lump sum prepayment made outside your regular EMI schedule is NOT eligible for Section 80C deduction.

Choosing tenure reduction saves you significantly more interest than reducing your EMI — it eliminates months or years of future interest accrual entirely. Choosing EMI reduction keeps your tenure the same, which means you pay interest for just as long. Unless you have a cash flow constraint and need the lower monthly outgo, tenure reduction is almost always the mathematically better option for Indian borrowers.

Floating rate home loans in India carry zero prepayment penalty — the RBI mandated this in 2012. If you're on a fixed-rate home loan, your lender may charge a foreclosure fee of 2–4% of the prepaid amount. Most borrowers in India are on floating rate loans linked to the repo rate (RLLR or MCLR), which means prepayment is completely free of charge.

Prepaying your home loan is typically better than an FD for borrowers on a rate above 8%, because the guaranteed interest saving on the loan outpaces the post-tax FD return. FD interest is taxed at your income slab rate — for someone in the 30% bracket, a 7% FD yields just 4.9% after tax. Your home loan interest rate is almost certainly higher than that, making prepayment the mathematically superior option in most cases in 2026.

Equity mutual fund returns held for more than 1 year are subject to Long Term Capital Gains (LTCG) tax at 12.5% on gains above ₹1.25 lakh per year, as updated in Union Budget 2024. The calculator applies this tax to the investment scenario so the comparison is on a post-tax basis — not a gross return basis that would flatter the investment option. FD returns are modelled at your applicable income tax slab rate.

The comparison is based on the opportunity cost principle — if you use ₹X to prepay your home loan, you save a fixed, guaranteed amount of interest over your remaining tenure. If you invest the same ₹X in a monthly SIP, you earn a variable, market-dependent return. This calculator models both scenarios using your actual loan figures and your chosen return assumption, then shows the net rupee difference — so you make the decision with data, not gut feel.
