Prepay Home Loan or Keep an FD? A Simple Rate Test (2026)
Short version: Compare your FD's after-tax return to your home loan's effective interest rate. Because FD interest is fully taxable at your slab rate, a fixed deposit paying 7% pre-tax often works out to only 4.5–5% after tax for someone in the 30% bracket — well below a typical 8.5–9.5% floating home loan rate. In almost every case, breaking or skipping the FD to prepay wins on pure numbers, unless the FD is your emergency fund.
Why the comparison isn't 7% vs 9%
It's tempting to compare the FD's quoted rate directly to your loan's quoted rate. That's the wrong comparison, because FD interest is added to your taxable income every year and taxed at your marginal slab rate, while a home loan prepayment's "return" (the interest you stop paying) is not taxed at all.
- A 7% FD for someone in the 30% tax slab nets roughly 4.9% after tax.
- A 7% FD for someone in the 20% slab nets roughly 5.6% after tax.
- Compare that against a floating home loan at 8.5–9.5% — even after any Section 24(b) benefit narrows the gap slightly, prepayment still comes out meaningfully ahead for most borrowers.
A worked example
Take a ₹3 lakh FD earning 7% and a home loan at 9% with several years remaining.
- Keep the FD: after 30% tax, you net about ₹14,700 a year on that ₹3 lakh — compounding slowly, fully liquid at maturity.
- Break the FD and prepay ₹3 lakh: you save 9% a year on that amount for as long as it would have remained outstanding — roughly ₹27,000 in the first year alone, and considerably more in total interest saved over the remaining tenure, since prepayment compounds against a reducing balance too.
The gap — roughly 4 percentage points a year — adds up fast over a multi-year horizon.
When keeping the FD makes sense anyway
- It's your emergency fund. Never break your liquid safety net to prepay — see our how much should you prepay guide on funding this first.
- It's about to mature and breaking it early costs a penalty that eats most of the benefit — in that case, just wait for maturity and prepay then.
- You have a specific near-term goal the FD is earmarked for (a planned expense within 6–12 months) — don't disturb goal-based savings for a marginal rate gain.
- You're already fully using your Section 80C limit and interest deduction, and the after-tax FD rate happens to be very close to your effective loan rate — in that narrow case the difference is small enough that either choice is reasonable.
The practical rule
If the FD isn't your emergency fund and isn't earmarked for something specific and near-term, run the after-tax FD rate against your loan's effective rate — for most floating-rate borrowers today, prepayment wins by a comfortable margin.

Frequently asked questions
Is it better to prepay a home loan or keep money in an FD? For most borrowers, prepaying wins because a home loan's effective rate (typically 8–9.5%) beats an FD's after-tax return (usually 4.5–6% depending on your slab), unless the FD is your emergency fund or earmarked for a near-term goal.
Does the FD's tax-saving option (5-year tax-saver FD) change this? It reduces your taxable income under the old regime up to the 80C limit, but the underlying FD interest is still fully taxable, so the after-tax return comparison still generally favors prepayment for a market-rate floating loan.
Should I break an existing FD to prepay my home loan? Only if it isn't your emergency fund, isn't earmarked for a near-term need, and any early-withdrawal penalty doesn't wipe out the rate advantage. Run the numbers before breaking it.
What if my home loan rate is close to the FD rate? Then the decision is closer, and factors like liquidity, discipline, and your comfort with debt matter more than the last fraction of a percentage point. Either choice is reasonable in that narrow case.
