Start with the right calculator
Home-loan prepayment vs investment
Compare using surplus money to prepay your home loan against investing it, including expected returns, inflation, tax benefit and freed-up EMIs.
Open the home-loan comparison calculatorReduce EMI or tenure
After a part-prepayment, see whether keeping EMI similar and reducing tenure saves more than lowering the monthly EMI.

If you have already decided to reduce loan cost, compare EMI reduction, tenure reduction, foreclosure, rate reset and balance transfer choices in one place.
Open the prepayment and transfer guideEMI affordability stress test
Check whether your current EMI still leaves enough room for expenses, savings and temporary income shocks before using surplus cash.

Reverse-check how much EMI capacity your income can safely support before deciding whether to keep liquidity invested.
Open the loan eligibility calculatorTax benefit impact
Estimate whether home-loan tax deductions materially change the true cost of borrowing before you prepay.

The Home Loan Prepayment vs Investment Calculator compares two full paths:
- Use the surplus amount to prepay the loan now.
- Invest the surplus amount instead.
It also considers:
- interest saved by prepayment;
- investment growth on the lump sum;
- investment of EMIs freed after the loan closes early;
- prepayment charges;
- inflation;
- optional loan tax benefit.
For a more general comparison across loan types, use the Loan Prepayment vs Investment Calculator.
A simple framework
1. Keep emergency money first
Do not use all liquid savings for prepayment. Once money goes into the loan, getting it back usually requires a new loan, top-up, overdraft or sale of an asset.
2. Compare post-tax returns with post-tax loan cost
The loan rate and investment return are not always directly comparable. Tax benefits can reduce the effective cost of a home loan. Taxes and exit loads can reduce investment returns.
3. Test conservative investment returns
If investment wins only under an optimistic return assumption, the decision is fragile. Re-run the calculator with lower returns and see whether the answer changes.
4. Consider timing
Prepayment made early in the loan can save more interest because more future EMIs remain. Late prepayment can still help, but the interest-saving effect may be smaller.
5. Decide what problem you are solving
If the problem is stress, reduce the EMI. If the problem is total interest, reduce tenure. If the problem is wealth creation, compare prepayment with investing and consider splitting the surplus.
Example comparison
Suppose you have:
- ₹40 lakh outstanding home loan;
- 8.5% annual interest;
- 10 years remaining;
- ₹5 lakh surplus;
- 11% expected post-tax investment return;
- no prepayment charge.
In this case, investing may look attractive if the return assumption is achieved. But prepayment becomes stronger if returns are lower, the loan rate rises, or you value certainty and lower debt more than market upside.

If you have already decided to reduce the loan
For operational decisions — when to prepay, whether to reduce EMI or tenure, how amortisation changes, whether to foreclose, or whether a balance transfer is better — use the Home Loan Prepayment and Balance Transfer Guide.
That guide keeps the repayment execution topics together, while this page stays focused on the prepay-versus-invest decision.

Final rule of thumb
Prepay if you want certainty, lower debt and peace of mind.
Invest if your EMI is comfortable, your emergency fund is ready, and your expected post-tax return is meaningfully higher than the loan cost.
Split the amount if both goals matter and the calculator result is close.
