What is XIRR in Mutual Funds: Meaning, Example, Formula, How to Calculate XIRR

Extended Internal Rate of Return or XIRR is a calculator that helps you figure out how much your money has grown, considering you’re investing or withdrawing at different times. It’s a simple way to measure your returns when cash flow is irregular.

Key Highlights

• XIRR shows the actual annual return on your mutual fund investment by factoring in every cash inflow and outflow.
• It works perfectly for SIPs and irregular investments, where money is added at different times.
• Unlike CAGR, XIRR reflects real-world investing, adjusting for market ups and downs and timing.
• Simple tools like Excel or apps make XIRR easy to calculate and use, even for beginners.

What is XIRR in Mutual Funds?

XIRR is a tool for calculating the true profit in terms of the percentage of your investment in mutual funds when you don’t invest all your money at once. People often invest in mutual funds through SIPs (Systematic Investment Plans), where they put in a small amount every month, or they might add lump sums and withdraw some money later. 

XIRR tells you the growth of your money over time, considering all these irregular inflows and outflows.

Example:

Let’s assume Akshay invests in a mutual fund

• January 1, 2023: She puts in Rs. 10,000 (this is her investment).
• July 1, 2023: She adds another Rs. 5,000.
• April 1, 2025: Her total investment is now worth Rs. 18,000, and she decides to check her returns.

Here, Akshay didn’t invest all her money at once (Rs. 15,000 total), and the value grew to Rs. 18,000 over time. XIRR calculates her annual return percentage, considering the different dates. Using a tool like Excel, his XIRR might come out to be 9.13% per year. 

This means her money grew by 9.13% annually, on average, despite the staggered investments.

What is the Importance of XIRR in Mutual Funds?

XIRR is important because it gives you a real picture of your earnings. Mutual funds aren’t like a bank fixed deposit where you put money once and get a fixed interest rate. In mutual funds:

1. You invest at different times: Like Akshay’s example, you might invest monthly or whenever you have extra cash.
2. Market changes daily: The value of your fund goes up and down.
3. You might take money out: Sometimes you redeem (withdraw) some units.

A simple return calculation like Akshay invested Rs. 15,000 and got Rs. 18,000, so he made 20% doesn’t work here because it ignored when the money went in or out. XIRR considers the timing, making it accurate and fair.

For example, if Akshay had invested all Rs. 15,000 on Day 1 and it grew to Rs. 18,000, his return might look different. XIRR adjusts for her step-by-step investments, so she knows exactly how his money performs.

Why XIRR is Relevant in Real-Life Investing?

XIRR is useful because real-life investing doesn’t happen in one go. Most people invest gradually, Rs. 5,000 one month, Rs. 10,000 the next, based on when they have money. Since investments happen at different times and markets fluctuate, XIRR helps measure returns accurately by considering the timing of every contribution.

The stock market also doesn’t grow in a straight line. It’s bumpy. XIRR smooths out these bumps and gives you one number to understand your growth.

Imagine you’re selling mangoes. Some days, you sell 10 mangoes for Rs. 100, and some days, you sell 5 for Rs. 50. XIRR is like figuring out your average profit per day, even though every day is different.

Formula of XIRR in Excel

You don’t need to calculate XIRR manually. It’s a complex formula that computers handle automatically. XIRR finds one annual rate of return that balances all your investments and withdrawals according to their dates. You just enter your cash flows and dates in Excel or a calculator, and it does the rest.

XIRR finds a single rate (percentage) that makes the value of all your investments equal to the value of all your returns, considering the dates. Mathematically, it’s this

=XIRR(VALUES,DATES)

• XIRR: The rate we’re trying to find.
• Values: cash inflows and outflows of all investments from start to end.
• Dates: dates of all investments made on.

In plain terms, it balances your inflows (investments) and outflows (returns) over time. You just need a tool like Excel or a financial calculator to do it.

How to Calculate XIRR in Excel

Let’s make this super easy with Akshay’s example again. You can calculate XIRR using Microsoft Excel or Google Sheets. Here’s how:

1. List your cash flows and dates:
2. Open Excel:
3. Use the XIRR function:

Press Enter, and you get like 9.13%

Benefits of Calculating XIRR in a Mutual Fund

Clear Picture: It tells you exactly how your money is growing, no guesswork.

Example:  Akshay knows her 9.13% is better than a 6% bank FD.

Compare Easily: You can compare different mutual funds or even other investments (like stocks or gold).

Example: If Akshay’s friend got 10% XIRR in another fund, he might switch.

Plan Better: Knowing your real return helps you decide if you’re on track for goals like buying a house.

Example:  Akshay wants Rs. 50,000 in 5 years, 9.13% XIRR tells him if he’s close.

Handles Complexity: Works even if you invest irregularly or withdraw money.

Example: If Akshay took out Rs. 2,000 in 2024, XIRR adjusts for that.

What is the Difference between XIRR and CAGR?

Final Word

XIRR is a simple yet powerful way to understand how your mutual fund investments have actually grown over time. It factors in every deposit, withdrawal and date, giving you a clear and realistic picture of your true annual returns.

Whether you invest Rs. 1,000 a month or larger amounts, XIRR helps you measure real performance and make smarter financial decisions. It’s easy to calculate using Excel or investment apps, making it a reliable tool for any investor.
