Prepay early for maximum benefit

Prepayments made in the early years of a loan save far more interest than the same amount paid later — most of your early EMIs go toward interest, not principal. Check with your lender for any prepayment charges (typically none on floating-rate home loans in India).

How the Loan Prepayment Calculator Works

You enter your existing loan details plus a one-time or recurring extra payment. The calculator re-runs the amortization schedule with that prepayment applied entirely to principal, and shows exactly how much interest you save and how many months earlier the loan closes.

Example Scenarios

Scenario Result
₹30 lakh loan, 8.5%, 20 years, ₹2 lakh one-time prepayment in year 3 Saves several lakh in interest, shortens tenure
₹20 lakh loan, ₹5,000 extra every month from year 1 Larger interest savings from prepaying earlier
₹10 lakh loan, one-time ₹1 lakh prepayment near the end Minimal interest saved — timing matters

Frequently Asked Questions

Common Mistakes to Avoid

  • Assuming there's always a prepayment penalty — RBI bans this on floating-rate individual home loans.
  • Prepaying very late in the loan tenure, when most of the EMI is already going toward principal anyway.
  • Prepaying instead of building an emergency fund first, leaving no buffer for unexpected expenses.
