What Is a Debt Mutual Fund: Types, Benefits, Risks & Taxation Rules

A debt mutual fund is a type of investment scheme that mainly puts your money in fixed-income instruments like corporate bonds, treasury bills, commercial papers, and government securities.

Suppose Kajal invests ₹4,00,000 in a short-term debt fund that yields an average return of 7.2% per annum. After 2 years, the value of her investment will be:

Maturity Amount = ₹4,00,000 × (1 + 0.072)² = ₹4,61,862 approx.

So, she earns nearly ₹61,862 without taking on much equity risk. This makes debt funds a practical option for those aiming for capital preservation along with modest growth. In this blog, we will understand how these funds work, their types, benefits, risks, and taxation rules.

How Do Debt Mutual Funds Work?

Debt mutual funds gather money from investors and invest it in instruments that provide fixed interest. The returns are generated in two ways:
 

1. Interest income: Just like Fixed Deposits, these funds earn interest on the bonds they hold.
2. Price appreciation: When interest rates fall, bond prices rise, and the fund's Net Asset Value increases.

For example, you, as an investor, put ₹3,00,000 in a gilt fund (a type of debt mutual fund) when the average yield is 7%. If interest rates fall by 1%, the value of long-term bonds rises significantly, say by 3%. So, your investment could become:

Maturity Amount = ₹3,00,000 × (1 + 0.03) = ₹3,00,000 × 1.03 = ₹3,09,000

This ₹9,000 gain came just from market dynamics without waiting for maturity.

For example, Sneha invested ₹2,00,000 in a debt mutual fund on April 5, 2023. She redeemed it on August 1, 2025, for ₹2,50,000.
 

• Capital Gain = ₹50,000
• Since the investment was made after 1 April 2023, tax is calculated based on Sneha’s income tax slab.

If Sneha falls in the 20% tax slab, then:
 

• Tax = ₹50,000 × 20% = ₹10,000

But if she is in the 10% tax slab, the tax would be:
 

• Tax = ₹50,000 × 10% = ₹5,000

From this example, you can conclude that the final tax amount entirely depends on the investor’s applicable income slab.
