Prepay your home loan or invest the surplus?
Most Indian advice on this question was written when home loan interest carried a large tax deduction. Under the new tax regime — now the default — that deduction is gone for self-occupied property, and the old conclusion no longer follows.
What changed, and why old advice is now wrong
Under the old tax regime, a self-occupied home loan carried two deductions: up to ₹2 lakh a year of interest under Section 24(b), and up to ₹1.5 lakh of principal repayment within the Section 80C limit. Together these could cut the effective cost of a home loan by two percentage points or more.
Under the new tax regime, verified as of August 2026, neither is available for a self-occupied property. Section 24(b) interest deduction: not allowed. Section 80C principal: not allowed. Sections 80EE and 80EEA: not available.
The one surviving case is a let-out property, where interest can still be deducted against rental income — though any resulting loss that exceeds rental income cannot be set off against salary beyond ₹2 lakh a year.
The practical consequence: if you are on the new regime with a self-occupied home, your loan's effective cost is now simply its stated interest rate. Roughly 8.5% instead of an effective 6.5% or lower. That is a significant shift, and it moves the answer toward prepayment.
Tax rules change and depend on your circumstances. Confirm your own position with a qualified CA before acting.
The comparison as it now stands
Prepaying earns you a guaranteed, tax-free return equal to your loan rate — around 8.5% for a typical borrower in 2026. There is no market risk and no tax on the benefit, because you are avoiding a cost rather than earning income.
Investing in equity has historically returned more over long periods, but with volatility, no guarantee, and now with tax: long-term capital gains on listed equity are taxable above the annual exempt threshold.
So the honest comparison is a guaranteed 8.5% tax-free against an uncertain, post-tax equity return. That is much closer than it was under the old regime, and for many borrowers prepayment now wins on a risk-adjusted basis.
Prepay early or not at all
Whatever you decide, timing dominates. Because interest is charged on the outstanding balance, a prepayment in year three removes far more future interest than the same amount in year fifteen.
On a ₹50 lakh loan at 8.5% over 20 years, a ₹5 lakh prepayment in year two saves roughly ₹14 lakh in interest and cuts around three years off the tenure. The identical ₹5 lakh in year fifteen saves a small fraction of that. Test your own numbers in the EMI calculator using the extra payment field.
Also: when you prepay, ask the bank to reduce the tenure rather than the EMI. Most default to reducing the EMI, which feels better monthly and saves far less. Reducing tenure captures nearly all of the benefit.
What comes before either choice
Two things take priority over both options.
Clear high-interest debt. Credit cards in India commonly run 36–42% annualised. Nothing else comes close, and no investment or prepayment competes with eliminating that.
Build an emergency fund. Six months of expenses, liquid. Money prepaid into a home loan is effectively gone — retrieving it means a top-up loan or a loan against property, at a worse rate and only if the bank agrees. A borrower who prepays aggressively and then faces a job loss with no cash is in a worse position than one who did neither.
The case for splitting
Prepaying and investing are not exclusive. Directing part of your surplus to prepayment and part to a diversified equity SIP captures the guaranteed return on one side and the growth potential on the other, while keeping some liquidity.
For most borrowers this is the sensible answer, and the psychological value of watching the loan shrink is real — a plan you actually stick to beats an optimal plan you abandon.
Frequently asked questions
Are home loan tax benefits available under the new tax regime?
For a self-occupied property, no. As of August 2026 the new regime does not allow the Section 24(b) interest deduction, the Section 80C principal deduction, or 80EE/80EEA. Interest on a let-out property can still be set off against rental income, with the loss set-off against other income capped at Rs 2 lakh. Confirm your position with a CA.
Is it better to prepay a home loan or invest in an SIP?
Under the new regime, prepaying gives a guaranteed tax-free return equal to your loan rate, typically around 8.5%, while equity returns are uncertain and taxable. That is much closer than it was under the old regime, and for many borrowers prepayment now wins on a risk-adjusted basis. Splitting the surplus is a reasonable middle path.
Should I reduce the EMI or the tenure when I prepay?
Reduce the tenure. Most banks default to reducing the EMI, which feels better each month but saves far less interest. Reducing the tenure captures nearly all of the benefit of the prepayment.
When is the best time to prepay a home loan?
As early as possible. On a Rs 50 lakh loan at 8.5% over 20 years, a Rs 5 lakh prepayment in year two saves roughly Rs 14 lakh in interest; the same amount in year fifteen saves a small fraction of that, because there is much less future interest left to cancel.
