Prepayment figures computed with the Quantum EMI engine on a 50,00,000 loan at 8.5% for 20 years: EMI 43,391, total interest 54,13,879 with no prepayment; balance after 12 EMIs 49,00,489; a 5,00,000 prepayment at month 13 keeps the EMI and closes the loan in 180 further months instead of 229. Verify with the EMI Calculator and the FD Calculator.
Step 1 - emergency fund first. Six months of expenses stays liquid before any prepayment or investment. Prepaying out of your buffer converts a safety cushion into illiquid home equity.
Step 2 - clear the most expensive debt. Credit cards at 36-42% and personal loans at 11-16% always come before home loan prepayment. Priority order is by rate, not by sentiment.
Step 3 - compare like with like. Your loan rate is a guaranteed post-tax return. Compare it against the post-tax, risk-adjusted return of the alternative. Eight percent guaranteed usually beats ten percent with a 25% drawdown risk if you might need the money in five years.
Step 4 - consider the split. If you are deeply uncertain, split the surplus: prepay part to lock in the guaranteed saving and invest part for growth. A 60-40 split keeps both levers working and removes the regret either way.
Step 5 - prepay early, not late. Interest is front-loaded. A 5 lakh prepayment in year 2 saves several times more than the same amount in year 15, because the remaining balance has less time to accrue interest.
RBI prohibits foreclosure charges on floating rate home loans to individuals, so prepaying a floating home loan in India is penalty-free. Ask your lender to apply the prepayment to reduce tenure rather than EMI if your goal is total interest savings - and the reverse if your goal is monthly cash-flow relief. Some loans allow both; state your choice explicitly, in writing.
Keep the tax angle in view: home loan interest on a self-occupied property remains deductible up to 2 lakh per year under the old regime. Prepaying too aggressively can consume the interest that would have been deductible - a consideration mainly if you are on the old regime with a large loan.
Is it better to prepay or invest?
Prepaying earns a guaranteed tax-free return equal to your loan rate. Fixed deposits usually lose to it after tax; a diversified equity portfolio can win over long horizons but carries market risk.
How much does a 5 lakh prepayment save?
On a 50 lakh loan at 8.5% over 20 years, about 16.04 lakh in interest and roughly 49 months, if made early and the EMI is kept constant.
Are prepayment charges legal on home loans?
Not on floating rate home loans to individuals in India - RBI prohibits them. Fixed rate loans may carry a penalty.
