Home Loan Prepayment vs Investing: Which Is Better?
1 Oct 2026You have an extra ₹10,000 a month. Should it go into the loan or into investments?
What prepayment does
For a ₹50 lakh loan at 8.5% for 20 years, adding ₹10,000 a month brings the loan down from 20 years to about 12 years 11 months. The interest falls from ₹54.1 lakh to ₹32.4 lakh, saving about ₹21.8 lakh. Test your own loan in the Loan Prepayment Calculator.
The investing side
If the same ₹10,000 a month earned 12% for 20 years, it could grow to about ₹1 crore. But that is an assumption. Equity returns are uncertain, and gains may be taxed.
How to think about it
| Prepay | Invest | |
|---|---|---|
| Return | Saves your loan rate (here 8.5%) | Uncertain, could be higher or lower |
| Risk | None | Market risk |
| Feels like | Certain saving | Possible growth |
A practical approach
- Build an emergency fund first, enough for 6 months of expenses.
- If your loan rate is high, lean toward prepaying.
- If your rate is low and you can handle market risk, lean toward investing.
- Many people split the extra money between both.
