In the early years of a home loan, most of each EMI goes towards interest. That's exactly why part-payments made early are so powerful: every rupee of principal you repay stops attracting interest for all the years that remain.
The example
Take a ₹50 lakh home loan at 8.5% for 20 years. The EMI is about ₹43,391, and over the full term you'd pay roughly ₹54.1 lakh in interest — more than the loan itself.
- ₹2 lakh once, at the start: saves about ₹8.05 lakh of interest and ends the loan 23 months sooner
- ₹50,000 every year (₹8 lakh in total over the life of the loan): saves about ₹11.5 lakh and ends it 44 months sooner
- The same ₹2 lakh, but used to lower the EMI instead: the EMI drops to about ₹41,656 and saves about ₹2.2 lakh
Shorter tenure or smaller EMI?
Keeping the EMI and shortening the tenure saves far more interest, because the loan stops earlier. Lowering the EMI makes sense when monthly cash flow is tight or you want breathing room. Many lenders let you choose, so ask before you pay.
Before you prepay
- Keep an emergency fund of 3–6 months of expenses first
- Compare your loan rate with what the money could reasonably earn elsewhere, after tax
- If you're in the old tax regime, remember the home-loan interest deduction under section 24(b) shrinks as interest falls
- Floating-rate home loans for individuals usually have no prepayment charges in India, but confirm with your lender
- Ask for an updated repayment schedule after every part-payment
