On a ₹50 lakh loan at 8.75% with 20 years remaining, an extra ₹7,000–₹8,000 per month typically cuts 4–5 years off your tenure. Use the monthly and annual prepayment inputs above to find the exact figure for your loan. The higher your outstanding balance and rate, the greater the impact of each rupee prepaid.
Monthly prepayment almost always saves more interest than an equivalent annual lump sum because your principal reduces every month instead of once a year. For example, ₹5,000 extra per month on a ₹40L loan at 8.75% saves roughly ₹2.1L more interest than a single ₹60,000 annual payment over the same period.
You can instruct your bank to either keep EMI the same and reduce tenure, or keep tenure the same and reduce EMI. Reducing tenure saves significantly more total interest. On a ₹50L loan at 8.75% with 15 years remaining, a ₹3L lump sum prepayment saves roughly ₹4.8L in interest when used to cut tenure, versus only ₹2.1L when used to reduce EMI. Unless cash flow is very tight, always choose to reduce tenure.
Most floating-rate home loans for individual borrowers do not carry prepayment penalties under RBI guidelines. Fixed-rate loans may have a foreclosure charge of 1–2%. Always confirm with your lender before making a large lump sum payment.
