Home Loan Prepayment
Calculate interest savings and tenure reduction by making a part-payment.
What is a Home Loan Prepayment Calculator?
A Home Loan Prepayment Calculator is a powerful mortgage tool that shows you exactly how much money and time you can save by paying off a chunk of your loan early. When you make a lump-sum "part-payment" towards your home loan, 100% of that money goes directly toward reducing your principal balance, which drastically cuts down your future interest burden.
How Prepayment Magic Works
Because home loans use a reducing balance method, your monthly EMI is split between Interest and Principal. In the early years of a 20-year loan, almost 80% of your EMI goes entirely toward interest! By making a prepayment, you force the principal down immediately, which means every future EMI pays off significantly more principal than before.
Two Prepayment Strategies
- Reduce Tenure (Recommended): You keep your monthly EMI exactly the same, but the loan gets paid off years earlier. This maximizes your interest savings.
- Reduce EMI: You keep the original 20-year tenure, but your required monthly payment drops. This is useful if you are facing cash-flow issues, but it saves you much less interest.
Why You Should Prepay
- Massive ROI: If your home loan interest rate is 9%, making a prepayment gives you a guaranteed, risk-free 9% return on your money (tax-adjusted).
- Debt Freedom: Prepaying just 5% of your loan balance once a year can shave 5 to 7 years off a 20-year mortgage.
The Mathematical Formula
Interest Saved = (Old EMI × Old Tenure) - (New EMI × New Tenure)
