Frequently Asked Questions

Why does Strategy A (keep EMI, reduce tenure) save far more interest?
Loan interest is calculated every month on the outstanding principal balance. By keeping your monthly EMI at the original amount, a much higher portion of each monthly payment goes directly towards reducing principal rather than interest. This creates an exponential acceleration that cuts years off your loan.
Are there penalties for prepaying a loan in India?
Under RBI directives, commercial banks and housing finance companies (HFCs) cannot charge any prepayment penalty or foreclosure fee on floating-rate individual loans (including home loans). Some fixed-rate personal loans or business loans may have prepayment fees, so always verify your loan agreement.
When is the best time in the loan tenure to prepay?
The earlier in your loan tenure you make prepayments, the higher your interest savings. During the initial years of a long-term loan (e.g. Years 1–7 of a 20-year home loan), interest constitutes 60–80% of each EMI. Prepaying during this phase eliminates years of compounding interest.
Is it better to prepay a home loan or invest in an equity SIP?
This depends on your loan interest rate versus expected investment return. If your home loan is at 8.5%–9.0% and you can earn 12%–14% CAGR in equity mutual funds, investing often generates higher net wealth over 15+ years. However, loan prepayment guarantees a risk-free, tax-free effective return equal to your loan interest rate.
