A worked example
A ₹50,00,000 home loan at 8.5% over 20 years produces an EMI of roughly ₹43,391/month — and over the full term, total interest paid comes to about ₹54,13,840, more than the original loan amount itself. Shortening the tenure to 15 years raises the EMI to around ₹49,238/month but cuts total interest to about ₹38,62,840 — a savings of over ₹15 lakh for roughly ₹6,000 more per month.
