XIRR in Mutual Funds: Meaning, Formula and Example

XIRR means Extended Internal Rate of Return. It is a way to figure out the annual return on investments when money goes in and out at different times. It looks at both how much you invested or withdrew and when you did it.

XIRR in mutual funds gives you a clearer and more accurate picture of how your portfolio is actually performing based on your real cash flows. This blog will guide you to know more about XIRR with an example, its advantages and more.

Quick Synopsis 

• XIRR calculates annualised returns for portfolios with irregular investments or withdrawals, making it ideal for SIPs and non-uniform cash flows.
• It factors in the exact date and amount of every transaction for a more accurate return.
• It combines all inflows and outflows into one annualised growth rate.

Understand XIRR in Mutual Funds with an Example 

Suppose you started a monthly SIP of ₹10,000 in a mutual fund and kept investing for 4 years. After 5 years, the total value of your investment grew to ₹8.5 lakh.

In this case, each ₹10,000 contribution was invested for a different period, with the first contribution being invested for the longest (5 years), and the last contribution being invested for the shortest (1 month). The return for each contribution will vary based on how long it was invested. 

Calculating the CAGR (Compound Annual Growth Rate) for each contribution would be complicated. To make this simpler, the CAGRs of all contributions are combined and adjusted to reflect a single, common growth rate. 

This overall growth rate is represented by XIRR for the mutual fund scheme for different schemes.

Advantages of Using XIRR to Calculate Returns from Mutual Funds 

The primary advantage of using XIRR in mutual funds is its ability to provide an accurate picture of your cash flow and investments. Other key advantages are:

Accurate Calculation of XIRR for Investments

XIRR takes into account every cash inflow and outflow, which gives you an annualised return that reflects the true performance of your investment.

Comparing Different Portfolios

Another key benefit of XIRR is its ability to compare portfolios with varying investment patterns. Since XIRR standardises the return over time, you can effectively compare the performance of different mutual funds, even if their investment schedules or amounts differ.

Time-Dependent Calculations

XIRR also factors in the timing of each investment. This allows investors to understand the exact duration for which their money has been in the market. Thus, it gives a more detailed view of how long-term investments have performed over time.

Why is XIRR More Appropriate to Calculate SIP Returns? 

Internal Rate of Return (IRR) calculates returns assuming equal time intervals between each investment, redemption or dividend. However, this assumption often does not match reality. For instance, SIPs may have different intervals due to varying month lengths or holidays. It leads to inaccurate results if we use IRR to calculate SIP returns.

XIRR in mutual fund investments for the actual dates of each transaction is more accurate. It adjusts for varying intervals between investments and redemptions and provides a true picture of your returns. 

This makes XIRR ideal for SIP investors, as it offers precise calculations by considering real-world timing.

Can We Use CAGR Instead of XIRR to Calculate Returns? 

CAGR gives us the annualised return of an investment over a specific period, assuming the investment grows at a steady rate. 

For example, if a mutual fund shows 3-year returns of 10%, a ₹10,000 investment three years ago would now be worth ₹13,310.

While calculating CAGR for a single lump sum investment is simple, it becomes complex for SIP investments.

For instance, if you invest ₹5,000 monthly for 3 years and your total portfolio value at the end is ₹2,00,000, you would need to calculate the CAGR for each of the 36 instalments made over the 3 years. This can get complicated.

The SIP XIRR calculator simplifies this by calculating a single return for all your investments, taking into account the exact date of each contribution. If you want to easily calculate returns on your mutual fund SIP, XIRR is the ideal method.

In Excel, the XIRR formula is: XIRR (value, dates, guess)

Final Word 

XIRR is a useful metric for mutual fund investors, especially when your investments do not happen on the same dates, like with SIPs or occasional lump-sum additions. This makes it a much more accurate way to see how your investments are truly performing. 

Since XIRR is available on most investment platforms, it is easy to refer to and has become an important part of long-term wealth tracking.
