Lump-sum vs extra EMI — which works better?

A bonus prepayment in year 2 saves more interest than the same amount paid in year 8 — because more of the early EMI goes to interest. If you have a one-time windfall, deploy it early. If you have a steady surplus, an extra ₹5,000–10,000 monthly is the easier habit and matches a mid-cycle lumpsum in total impact.

Prepayment penalty — the rule

For floating-rate home loans for individuals, RBI prohibits prepayment penalty (Aug 2012 circular). Fixed-rate or business loans can have penalties — typically 2-4% of the prepaid principal. Always check your sanction letter.
