FD vs mutual funds — why the risk is different

The return of an FD is contractual

When a bank offers a 7.5% FD, that rate is a contract for the tenure. Barring the bank failing — which is why deposit insurance exists up to ₹5,00,000 per depositor per bank — you know what you will get. There is no market to fluctuate.

The return of a mutual fund is not contractual. An equity fund reflects the value of the underlying stocks; a debt fund reflects the value of the bonds it holds. Both change every day. Past averages are not a promise.

Tax treatment moves the finish line

FD interest is added to your income and taxed at your slab rate. In the 30% slab, a 7.5% FD lands closer to 5.2% after tax. That gap is not a rounding error — it is the entire reason to think about the safe bucket in after-tax terms.

Equity mutual funds held over 12 months qualify for long-term capital gains at 12.5%, above a ₹1,25,000 per-year exemption. Held under 12 months, it is 20%. Debt funds bought after April 2023 are taxed at slab like an FD, so they lost the old indexation edge.

Different risks, different jobs

• FDs answer the question "how do I make sure money I will need in 6 months is still there in 6 months?" They trade upside for certainty.
• Equity mutual funds answer "how do I grow money that I do not need for 7+ years, accepting that it will fall 30% at some point along the way?" They trade certainty for upside.
• Debt mutual funds sit in between and are useful for horizons of a few years, but the 2023 tax change has made them look more like FDs for many investors.

The right question

The useful question is not "which is better" but "what is this money for, and when will I need it". Match the instrument to the horizon and the risk you can afford — then, and only then, look at the post-tax return.
