Every time you inject a lumpsum payment into your outstanding loan, you directly attack the principal. Due to the amortization structure, banks continuously charge interest on the remaining principal. This calculator models how a one-time prepay event of alters the amortization curve, ultimately saving you lakhs of rupees in unnecessary interest payouts.
The 'Early Bird' Prepayment Rule
The most effective time to prepay a home loan is in the first 25% of its tenure. Since early EMIs are heavily front-loaded with interest, a ₹1 Lakh prepayment in the 2nd year can eliminate up to ₹4 Lakhs in future interest. If you wait until the 15th year of a 20-year loan, the same prepayment saves very little, as you've already paid the bulk of the interest.
ROI vs ROI: Prepay or Invest?
If your home loan interest is 8.5% (effective ~6.5% after tax benefits) and you can earn 12% in an Index Fund, mathematically, you should invest. However, prepaying gives a guaranteed return, while the market is volatile. For most Indian families, a hybrid approach—investing 70% and prepaying 30% of surplus—is the most balanced strategy.
The Tax Benefit Paradox
Many borrowers avoid prepaying because they want to keep the Section 24b tax deduction (up to ₹2 Lakhs). However, remember that you are paying ₹1 to save 30 paise in tax. The total interest you save by prepaying is always mathematically superior to the tax benefit you 'lose'.
