Making even one extra EMI payment a year, or a lump-sum prepayment whenever you have surplus cash (like a bonus), can shave years off a 20-year home loan because it directly reduces the principal early, when interest is compounding on the largest balance.
A shorter tenure at the same EMI, or a small increase in EMI each time your income rises, both cut total interest dramatically compared to leaving the loan on autopilot for the full original term.
It’s also worth periodically comparing your current interest rate against what new borrowers are getting — refinancing or requesting a rate reduction from your existing lender can be worthwhile if the gap is wide enough to outweigh the switching costs.
Example.On a ₹50 lakh, 20-year loan at 8.5%, prepaying ₹1 lakh once a year can cut the effective tenure by several years and save well over ₹5 lakh in total interest.
