FD or debt mutual fund: which is better now?

For years the case for debt funds over FDs was tax. That changed in April 2023, and for most people the tax gap has nearly closed. What is left is a choice about safety, access to your money and how long you will hold it, so here are the numbers and the cases where each one wins.

What changed in 2023

For debt fund units bought on or after 1 April 2023, all gains are taxed at your income-tax slab rate, however long you hold them, and the old long-term rate with indexation no longer applies. FD interest has always been taxed at your slab rate. So on tax rate alone the two are now the same, and the one difference left is timing: FD interest is taxed every year as it is earned, while a debt fund's gain is taxed only when you sell. Units bought before April 2023 and held for more than two years are taxed differently, at 12.5% without indexation, so check the purchase date before you switch old money.

One sum, worked through

Take ₹5 lakh. Put it in an FD at 7% compounded quarterly, with the tax on the interest paid each year, or in a debt fund that earns 7% a year after its costs, with the tax paid when you sell. Here is what you keep:

Over three years the two are almost level, and the FD is a few hundred rupees ahead because quarterly compounding makes 7% work out to about 7.19% a year. Over ten years the fund is ahead by about ₹22,600, because tax that is paid only at the end leaves more money compounding in the meantime. In the 5% slab the FD stays ahead even at ten years, because there is little tax to defer. The fund's 7% is an assumption and the FD's is fixed, so treat the fund column as an example of the method, and run your own numbers.

The differences that matter more than tax

1. Safety. Deposits in a bank are insured by DICGC up to ₹5 lakh per depositor per bank. A debt fund has no such cover, and its value can fall when interest rates rise or when a company it lent to fails to repay.
2. Access. Breaking an FD early usually costs you part of the interest, as a penalty set by the bank. A liquid or overnight fund can usually be sold on any working day, with the money in your account the next working day.
3. TDS and paperwork. Banks deduct TDS on FD interest above ₹50,000 a year (₹1 lakh for senior citizens), and you report the interest every year. A debt fund has nothing to report until you sell.
4. Choosing. One FD is like another, but debt funds differ a lot in what they hold and how long they lend for, so picking one needs more care, and the cheaper direct plan is worth the effort to find.

When the FD is the better choice

1. The money is needed within about three years, where the after-tax returns are close and the FD's fixed rate removes the guesswork.
2. You are in the 5% slab or below the taxable limit, where there is little tax to defer.
3. You want the deposit insurance, and you keep each bank's total within ₹5 lakh.
4. You would worry about seeing the value dip, even if only for a few weeks.

When a debt fund is the better choice

1. A large safe portion, held for ten years or more, in the 20% or 30% slab, where paying tax only at the end adds up.
2. Money you may need at short notice, where a liquid fund avoids the FD's early-exit penalty.
3. You want to spread safe money beyond the ₹5 lakh that DICGC covers in one bank, and you choose funds that lend to the government and the strongest borrowers.

Many people end up using both, with FDs for near goals and the first part of the emergency fund, and a debt or liquid fund for the rest, and that is a reasonable split.
