Bonus Windfall: Prepay Loan Or Invest It?

Say you have a ₹50 lakh home loan at 8.5%, 20-year tenure, EMI ₹43,391. Put a ₹1 lakh bonus toward prepayment in year 2, and you save roughly ₹3.5–4 lakh in total interest, shaving almost a year off your tenure.
Now invest that same ₹1 lakh in an equity SIP earning 12% average annually for 18 years — it grows to nearly ₹7.7 lakh.
On paper, investing wins. But prepayment is a guaranteed, risk-free return equal to your loan rate.

What this means for you

• Prepaying ₹1 lakh now cuts future interest outgo — like a safe, certain gain.
• Investing the same ₹1 lakh could beat that gain, but only if markets cooperate over the long run.
• Your loan's real interest cost (after your home loan tax deductions) may already be lower than 8.5%.

What you can do

• If your loan rate is above 9% or you're debt-averse, prepay — it's the safer win.
• If you have 7+ years and no emergency fund gap, let the bonus work in equity instead.

There's no universally right answer here — just the one that matches your comfort with risk and your loan's real cost.
