What is Expense Ratio? Meaning, Formula & Importance in Mutual Funds

The expense ratio in mutual funds is the percentage of your money that is used to pay for managing your fund. This cost is not paid separately; it is quietly taken every day from the fund's value.

Ravi Mehta, a school teacher in Indore, wanted to invest ₹10,000 in a mutual fund for his daughter’s future. He selected two mutual funds. One had an expense ratio of 2% and the other had 1%. Over 5 years, Ravi noticed something surprising. The fund with the lower expense ratio gave him ₹14,000. 

The other one, though having the same returns before costs, gave him only ₹13,000. The ₹1,000 difference was the cost of the higher expense ratio. “Itna sannata kyun hai bhai?”,  Ravi thought, shocked. He hadn’t realised how a small percentage could take away so much from his future returns.

This blog will help you learn more about the expense ratio and its formula.

What is the Expense Ratio in a Mutual Fund?

The expense ratio in mutual funds shows how much of your investment is taken as a fee by the Asset Management Company (AMC) to manage your money. It is not paid separately. Instead, it is removed quietly every day from your investment value.

Let’s take an example. Neha Sharma, a college student from Jaipur, invested ₹5,000 in a mutual fund. The expense ratio of the fund was 2%. This meant ₹100 was being charged yearly to manage her investment. 

Every single day, about ₹0.27 was automatically taken out, without her needing to do anything. Neha didn’t notice it at first. But after a year, when she compared it with another fund with a 1% expense ratio, she realised her returns were lower.

The expense ratio may seem small, but over time, it can reduce your final earnings. As the saying goes, “Thoda thoda karke sab kuch chala jaata hai.”

Expense Ratio Formula:

The expense ratio is calculated using a simple formula. It helps you understand how much of your money is used to run the mutual fund. The formula is:

Expense Ratio = Total Expenses ÷ Average AUM

Here, AUM means Assets Under Management, or the total money handled by the fund.

Let’s look at Arjun Patel, a shopkeeper from Surat. He picked a fund that managed ₹700 crore. The total cost to run the fund was ₹14 crore. So, using the formula:

₹14 crore ÷ ₹700 crore = 2%

This told Arjun that 2% of the money in the fund was used to cover costs like salaries, audits, and promotion. He realised this percentage could make a difference in his returns over time. “Chhoti chhoti cheezein, bada farak daalti hai,” he thought.

What are the Components of the Expense Ratio?

The expense ratio is not just one cost. It is a mix of small charges put together. Each part pays for a specific job in managing your mutual fund.

Let’s see how this worked for Pooja Rathi, a young IT professional from Pune. She noticed that ₹150 was taken yearly from her ₹7,500 fund. Curious, she asked her fund advisor. He explained that the money went to three main areas:

1. Fund Manager’s Fee – to pay the expert managing the fund
2. Legal/Audit Charges – to ensure the fund follows all rules
3. Marketing & Distribution Fees – to promote and run the fund

Pooja laughed and said, “Rishtey mein toh hum tumhare baap lagte hain… lekin paisa le jaate ho har din chupke!”

Even small costs like these matter over time. It’s always good to know where your money goes.

SEBI Limits on Expense Ratio:

The Securities and Exchange Board of India (SEBI) has placed limits on how much mutual fund companies can charge investors. These limits depend on the fund size. Larger funds are allowed to charge less.

Iqbal Khan, a retired railway officer from Lucknow, compared two equity mutual funds.

• Fund A had an AUM (Assets Under Management) of ₹400 crore and charged a 2.25% expense ratio.
• Fund B had ₹6,000 crore AUM and charged only 1.5%.

He was confused. “Why does the big fund cost less?” he asked his son. His son explained that SEBI sets rules, big funds have to charge less to protect small investors. Iqbal now understood that a bigger AUM means lower costs for each investor.

Expense Ratio in Passively Managed Funds:

Passively managed mutual funds usually follow an index. Because they don’t need an expert to manage them every day, they cost less.

Meera Nair, a school principal in Kochi, invested in an index fund. It had an expense ratio of just 1%. She compared it to an active fund that charged 2.25%. Over time, she saved more money with the passive fund. That’s when she said, “Kam paisa lo, zyada bacha lo.”

Expense ratios for passive funds are capped too, and SEBI has made clear rules for each type.

Impact on Returns:

Even a small change in the expense ratio can lead to a big difference in how much money you make.

Rohit Joshi, a banker from Bhopal, invested ₹1 lakh in two funds:

• Fund A had a 1% expense ratio, and after 10 years it grew to ₹2.15 lakh.
• Fund B had a 2% ratio and gave him ₹1.95 lakh.

He earned ₹20,000 less, even though both funds gave the same return before expenses. Rohit smiled and said, “Bade bade deshon mein, aisi choti choti cheezein hoti rehti hai.” But then added, “Lekin investment mein nahi honi chahiye!”

Expense ratios reduce your net return, especially in the long run.

Regular vs Direct Funds:

There are two types of mutual fund plans: Regular and Direct. Regular plans involve agents or distributors and cost more. Direct plans go straight through the fund house and cost less.

Kirti Deshmukh, a homemaker from Nagpur, chose a regular plan for ₹50,000. Her cousin selected a direct plan with the same amount. After 5 years:

• Kirti’s regular fund grew to ₹70,000
• Her cousin’s direct fund reached ₹75,000

Kirti lost ₹5,000 just because of higher expense charges.

Use Expense Ratio as Comparison Tool:

When choosing between mutual funds, checking the expense ratio helps you find the cost-effective one.

Faizan Alam, a college lecturer in Hyderabad, wanted to invest ₹50,000. He compared three funds offering the same 9% return.

• Fund A had 1.8% expense ratio
• Fund B had 1.2%

After 3 years,

• Fund A gave him ₹64,000
• Fund B gave him ₹66,000

By choosing a lower expense fund, Faizan earned ₹2,000 extra. He now tells everyone, “Compare karo, fir invest karo.”

Why Expense Ratio Matters for Debt Funds?

The expense ratio is even more important in debt mutual funds, which give lower returns.

Sneha Kapoor, a chartered accountant in Delhi, invested in a debt fund offering 6% annual return. The fund had a 2% expense ratio, so her net return was only 4%. This return was just enough to fight inflation, but not to grow her money.

For Sneha, this made it clear that when returns are already small, every percentage charged matters even more.

“Khud pe kharcha theek hai, lekin returns ke paison pe nahi,” she told her friend.
