A common trap is ignoring the time difference. If you prepay, the loan ends early. What if you invested the EMI amount for the remaining years?
Verdict: Invest Surplus creates a larger corpus by ₹9,67,370 at the end of original tenure.
A common question for anyone with a home loan is whether to use extra cash to pay off the loan or invest it to grow their wealth. This calculator helps you compare both paths so you can see which one makes more financial sense for you.
Option 1: Prepayment involves paying off a portion of your outstanding principal early. This directly reduces the interest you pay over the remaining tenure, offering a risk-free return equivalent to your loan interest rate.
Option 2: Investment involves using that same surplus amount to invest in assets like Mutual Funds (SIP), Stocks, or Fixed Deposits. If your investment returns exceed your loan interest rate, this option generates wealth.
The decision mostly depends on comparing your Loan Interest Rate against your Expected Investment Return.
If Investment Return > Loan Rate: Investing is generally better. The wealth you create will exceed the interest you save.
If Loan Rate > Investment Return: Prepayment is better. It guarantees a risk-free return equal to your loan rate.
Tax Benefits: Home loans offer tax deductions under Section 24(b) (Interest) and 80C (Principal). Prepaying reduces your interest outgo, potentially reducing your tax benefits.
Psychological Peace: Being debt-free has immense psychological value that a spreadsheet cannot capture.
Liquidity: Investments are usually more liquid than locked-in home equity.
We simulate two parallel universes for you:
Scenario A (Prepay): You use your extra cash to make loan payments. We show you how much interest you save and how much sooner you'll be debt-free.
Scenario B (Invest): You keep your loan as is and invest the extra cash instead. We calculate how much that investment could grow over time.
*For monthly investments (SIP), we use the Future Value of Annuity formula: P × ([ (1+r)^n - 1 ] / r) × (1+r).*
The Result: We compare the potential investment gains against the interest savings to show you which choice leaves you with more money in the end.
