How much does prepaying save?

Got a bonus or some savings? Putting it towards your loan is a guaranteed way to cut interest. This loan prepayment calculator compares your loan as it stands with two choices after a prepayment: keep the same EMI and finish years earlier, or keep the same end date with a smaller EMI. Add a regular extra amount each month to see how small top-ups add up.

How to use it

  1. Enter the original loan amount, interest rate and tenure.
  2. Enter a one-time prepayment and when you'll make it, and/or an extra monthly amount.
  3. Compare total interest and tenure across the options.

Example

A ₹30 lakh home loan at 8.5% for 20 years has an EMI of about ₹26,035 and total interest of about ₹32.5 lakh. Prepaying ₹5 lakh after 2 years and keeping the EMI finishes the loan68 months earlier and saves about ₹12.9 lakh of interest. Keeping the tenure instead drops the EMI to about ₹21,507 but saves only ₹4.8 lakh. Even ₹5,000 extra a month from the start saves about ₹11.7 lakh and 76 months. Check your EMI first with the EMI calculator.

Tips

  • Ask the bank to reduce tenure rather than EMI when you prepay, if you can afford the EMI.
  • Keep 6 months of expenses as an emergency fund before prepaying.
  • Remember the tax deduction on home-loan interest under the old regime when comparing with investing.

Frequently asked questions

Is it better to reduce EMI or tenure after prepaying?
Reducing the tenure (keeping the same EMI) saves much more interest, because the loan is paid off sooner. Reducing the EMI eases your monthly budget but saves less. The calculator shows both side by side.
Are there charges for prepaying a home loan?
RBI rules don’t allow banks and other regulated lenders to charge prepayment or foreclosure penalties on floating-rate loans to individuals, such as most home loans. Fixed-rate loans can carry charges — check your loan agreement.
When is the best time to prepay?
As early as possible. In the first years most of each EMI is interest, so every rupee prepaid early cuts the most future interest.
Should I prepay or invest?
Prepaying earns a guaranteed “return” equal to your loan rate (after tax benefits). If you can reliably earn more by investing — and keep an emergency fund — investing may build more wealth; many people do a bit of both.
