Buying a home is one of the biggest financial commitments for most people. While opting for a longer loan tenure helps reduce the monthly EMI, it also increases the total interest paid over the life of the loan. EMI calculator can help borrowers estimate their EMI, total interest outgo, and repayment schedule before taking a loan.
Some borrowers also consider investing in a Systematic Investment Plan (SIP) alongside their regular EMI. Over time, the SIP may build a corpus that can be used for a part-prepayment of the loan, potentially reducing the remaining tenure and interest burden.
Assume you take a home loan of ₹50 lakh at an interest rate of 8.5% per annum for 30 years.
Particulars | Value |
Loan Amount | ₹50 lakh |
Interest Rate | 8.5% p.a. |
Loan Tenure | 30 years |
Monthly EMI | ~₹38,445 |
Total Amount Payable | ~₹1.38 crore |
Total Interest Payable | ~₹88.40 lakh |
Although the EMI remains manageable, the interest paid over 30 years exceeds ₹88 lakh.
Now assume that instead of increasing the EMI, you invest ₹10,000 every month in an equity mutual fund through a SIP, earning an assumed annual return of 12%.
Particulars | Value |
Monthly SIP | ₹10,000 |
Investment Period | 15 years |
Total Investment | ₹18 lakh |
Assumed Annual Return | 12% |
Estimated Corpus | ~₹50 lakh |
After paying EMIs for 15 years, a substantial portion of the home loan principal is still outstanding. If the SIP has grown to around ₹50 lakh, you may be able to use the accumulated corpus to make a one-time prepayment.
Depending on the outstanding loan balance, the prepayment could significantly reduce the remaining loan tenure or, in some cases, help close the loan much earlier than the original 30 years. However, whether the loan can be fully repaid in exactly 15 years depends on factors such as:
Home loan interest rate
Original loan amount
SIP return earned
Timing and amount of the prepayment

Before using a SIP to prepay a home loan, keep these points in mind:
SIP returns are market-linked and can be higher or lower than expected.
Home loan interest rates may change if the loan is on a floating rate.
Check whether your lender has any conditions for part-prepayment.
Ensure you have an emergency fund before using your investment corpus to reduce debt.
Review the strategy periodically to ensure it aligns with your financial goals.
Investing ₹10,000 every month in a SIP while continuing to pay your home loan EMI can help create a sizeable corpus over the long term. Using that corpus for a part-prepayment may reduce your home loan tenure and lower the total interest paid.
