Free Prepayment Calculator — No Sign-up Required
Enter your outstanding loan balance, interest rate, remaining tenure, and the lump-sum amount you plan to prepay. Instantly see how much interest you save and how many months you cut off your loan.
Enter the current outstanding principal — not the original loan amount. Check your latest bank statement or loan account portal.
Enter the number of months or years still left on the loan — not the original tenure.
The lump-sum amount you plan to pay now, in addition to your regular EMI. Check with your lender for any prepayment charges first.
Reducing tenure saves more interest overall. Reducing EMI improves monthly cashflow. Most financial advisors recommend reducing tenure.

Interest Remaining vs Saved
See how the prepayment accelerates your loan payoff compared to the original schedule.
Loan Balance — With vs Without Prepayment
Every rupee saved on interest is a rupee that can compound elsewhere. Add your loan to the Net Worth Calculator to see its impact on your projected wealth — or calculate the original EMI on a new loan with the EMI Calculator.
This is the current principal you still owe — not the original loan amount. Find it in your latest bank statement, loan account portal, or by calling your lender.
Use your current applicable rate. For floating-rate loans, use today's rate. Enter the years or months still remaining on the loan — not the original tenure.
How much do you plan to pay as a lump sum today? Check your loan agreement for prepayment charges — many home loans have nil charges after the first year.
Reduce Tenure keeps your EMI the same but you become debt-free sooner — maximising total interest savings. Reduce EMI keeps the same tenure but lowers your monthly payment, improving cashflow.
See your total interest saved, new tenure or new EMI, and the chart comparing how your outstanding balance drops with and without the prepayment.
Outstanding: ₹30L | Rate: 8.5% | Remaining: 15 yrs | Prepayment: ₹5L | Strategy: Reduce Tenure
Both strategies reduce your total interest paid compared to making no prepayment. However, reducing tenure saves more interest because the principal is cleared faster, reducing the base on which interest compounds.
Interest Saved = Total Interest (original) − Total Interest (after prepayment)
For floating-rate home loans from banks, RBI guidelines prohibit prepayment penalties. Fixed-rate loans and loans from NBFCs may still have charges (typically 1–4% of the prepaid amount). Always check your loan agreement before prepaying.
Early in the loan tenure — when the outstanding principal is highest and most of your EMI is going toward interest. A prepayment in year 2 of a 20-year loan saves far more than the same prepayment in year 15.
Compare your loan interest rate to the post-tax return on your investment. If the loan rate (e.g. 8.5%) is higher than the expected post-tax investment return, prepaying wins. If you can reliably earn more after tax (e.g., equity SIP at 12%), investing may be better — though prepaying provides a guaranteed, risk-free return equal to your interest rate.
This calculator models a single lump-sum prepayment made now. For a series of prepayments over time, run the calculator after each payment by updating the new outstanding balance and remaining tenure.
