What is Loan Prepayment?
Loan prepayment means making a payment over and above your scheduled EMI, applied directly to your outstanding principal. Since your future interest is calculated on the remaining balance, reducing the principal reduces every subsequent month's interest charge. Over a long tenure like 20–30 years, the compounding effect of this interest reduction is dramatic. A ₹5 lakh prepayment on a ₹50 lakh home loan early in the tenure can save ₹8–12 lakh in total interest and cut 2–4 years off the loan.
How Much Can You Save by Prepaying?
The savings depend on three factors: the prepayment amount, when you make it, and your loan's interest rate. The earlier in the tenure you prepay, the more interest you avoid — because the prepaid principal would have attracted interest for many remaining years. At 8.5% on a 20-year loan, every ₹1 lakh prepaid in year 2 saves approximately ₹1.4–1.6 lakh in total interest. Monthly prepayments (even small ones, like ₹5,000/month extra) have a powerful compounding effect over time. Use the calculator above to model your exact scenario.
When is the Best Time to Prepay?
Prepay as early in the tenure as possible — the first 5 years are the most interest-heavy. In a standard amortization schedule, over 70% of your EMI in the early months goes toward interest. Prepaying in this period eliminates principal that would have attracted interest for the longest remaining period. If you receive an annual bonus, a salary hike, or a windfall, put it toward prepayment before considering other investments — the guaranteed "return" of eliminating 8–9% home loan interest is hard to beat risk-free.

Frequently Asked Questions
What is loan prepayment?
Loan prepayment means paying an amount over and above your regular EMI, directly reducing the outstanding principal. This reduces the total interest you pay because future interest is calculated on a lower balance. There are two types: partial prepayment (paying extra without closing the loan) and full foreclosure (repaying the entire outstanding balance at once).
Does prepayment reduce EMI or tenure?
Most Indian banks give you the choice. Reducing tenure keeps your EMI the same but you repay the loan faster — this saves more total interest. Reducing EMI keeps the tenure the same but lowers your monthly payment. If your goal is to save the most interest, always choose to reduce tenure when making a prepayment.
When is the best time to prepay a home loan?
Prepayment saves the most interest when done early in the loan tenure — in the first few years when the interest component of each EMI is highest. A prepayment in year 2 of a 20-year loan saves significantly more than the same prepayment in year 15. Even a small prepayment in the first 5 years can cut 2–3 years off your loan tenure.
Do banks charge a penalty for prepayment?
Many floating-rate loans have no prepayment charge, but terms differ by lender and product — check your loan agreement or ask the lender before prepaying.
How much should I prepay to save significantly?
Even prepaying 5–10% of the outstanding principal once a year can reduce your total tenure by 3–5 years on a 20-year home loan. Use this calculator to model different scenarios. As a rule of thumb: for a ₹50 lakh loan at 8.5% for 20 years, a one-time prepayment of ₹5 lakh in year 2 saves approximately ₹8–10 lakh in total interest.
