What Is a Mutual Fund Expense Ratio Impact Calculator?

A Mutual Fund Expense Ratio Impact Calculator helps investors understand how mutual fund fees can affect long-term investment returns.

What Is an Expense Ratio?

An Expense Ratio is the annual fee charged by a mutual fund scheme for managing investor money.

It covers:

• Fund management
• Administration
• Operations
• Distribution costs (where applicable)

Expense ratios are expressed as a percentage of assets under management.

Example:

Investment:
₹1,00,000

Expense Ratio:
1%

Annual Cost:
₹1,000 (approximately)

---

Why Is Expense Ratio Important?

A difference of:

0.5% to 1%

may appear insignificant.

However, over long periods, compounding can magnify this difference substantially.

Small costs today can translate into large wealth differences decades later.
