What Is XIRR in Mutual Funds? How Is it Different from CAGR?

XIRR meaning

XIRR is a method used to compute annualised returns from mutual funds applicable for investments made via systematic investment plans (SIPs). It is a single rate of return applicable for every SIP instalment and redemption.

XIRR in mutual funds gives the annual average return for each SIP instalment. Unlike CAGR, it accounts for irregular cash flows and multiple periods, making it an essential tool for analysing mutual fund returns.

Importance of XIRR

XIRR is crucial for measuring returns when investments are made at different times, such as SIPs. It accounts for irregular cash flows and reflects the true annualised return, helping investors understand how effectively their money is actually growing over time.

XIRR advantages and limitations

The advantages of XIRR are as follows:

• More accurate performance measurement

XIRR helps you measure the performance of your mutual fund investments more accurately. This is because it factors in the exact timing of cash flows. Also, since it considers withdrawals, it helps you measure the performance of your mutual funds in a more nuanced manner.

• Factors in time value for money

XIRR factors in the time value of money by factoring in specific dates and cash flows. Thus, it helps you evaluate the actual return on your investment.

• Helps compare different investment options

XIRR enables you to compare returns across various investment avenues like mutual funds, fixed deposits, or real estate. Since it standardises returns by accounting for timing and cash flow variations, you can make informed decisions by evaluating which option has delivered better real-world returns over time.

• Simplifies portfolio tracking

XIRR allows you to track the overall performance of your portfolio even if it includes multiple funds and irregular transactions. By consolidating all cash inflows and outflows with their respective dates, it gives a single annualised return figure, making portfolio performance easier to understand and monitor.

Limitations of XIRR

• Warrants accurate cash flow data

XIRR requires you to input accurate and complete cash flow data. This includes the date and amount of each cash flow. If you input incomplete or inaccurate data, it can affect the calculation.

• Sensitive to small changes in data

XIRR is a sensitive metric. Even minor alterations in cash flow data can make it challenging to compare different funds based solely on XIRR returns.

• Not useful for predicting future returns

XIRR is a retrospective metric that calculates historical performance based on past cash flows. It does not account for future market conditions, making it unsuitable for forecasting future returns or making forward-looking investment decisions.

• Difficult to interpret for short-term investments

XIRR can produce misleading or exaggerated results when applied to very short-term investments with limited transactions. Since it's an annualised figure, a small gain over a few days can show an inflated return, making it harder to assess real performance over short periods.

XIRR Formula and Example

You can quickly compute XIRR in MS Excel using the XIRR function. The formula to calculate XIRR in Excel is:

=XIRR (Values, Dates, [Guess]), where

• Values are the total amount invested, including redemption. For every SIP, the value is negative, whereas the investment value on the date of the XIRR calculation should be positive.
• Dates refer to the investment date
• Leave the guess part blank

To calculate XIRR in Excel:

• Enter the investments done on various dates in one column
• Enter the date of each transaction in another column
• Enter the current value of your investment along with the date in the last row
• Use the XIRR function given above in another row

Assuming you start an SIP of ₹10,000 on 10th January 2023 and continue investing the same amount throughout the year on the same date. As of 10th December 2023, your maturity amount is Rs 1.3 lakhs. In this case, the XIRR of your investment stands at 18.4% (see image below).

CAGR Meaning

CAGR is used to calculate the annualised return of your mutual fund investment when cash flow occurs at regular intervals. Assuming a constant growth rate over a specific period, it computes the average rate of returns during that period.

CAGR is most effective when there is a single investment and a single redemption, such as in lump sum mutual fund investments. It smooths out the volatility in returns by assuming steady growth, which helps you understand how your investment would have grown if it had progressed at the same rate every year.

CAGR Advantages

CAGR in mutual funds offers the following advantages:

• Easy to comprehend and calculate

CAGR is a simple metric that even beginners can understand. It shows the average annual growth rate of an investment over a set period. Since it assumes a steady growth path, it eliminates the complexity of daily market fluctuations, making performance evaluation more straightforward and consistent across different investment options.

• Helps compare fund performance over a specific period

CAGR allows you to compare the historical performance of various mutual funds over identical time frames. This standardisation helps in objective fund selection by offering a clear picture of past returns. Whether comparing equity or debt funds, CAGR gives a uniform benchmark for evaluating long-term investment outcomes.

• Helps assess long-term investment performance

CAGR is particularly useful for evaluating long-term investments, as it smooths out short-term market volatility. It provides a realistic view of how your investment has grown annually over time, making it ideal for assessing mutual fund performance over 3-, 5-, or 10-year periods and supporting informed financial planning decisions.

CAGR Limitations

• Constant growth assumption

CAGR assumes that the investment grows at a steady, uniform rate throughout the specified period. In reality, market movements are rarely consistent and returns often vary significantly year to year. This assumption can oversimplify actual performance and may mislead investors about the risks or irregular growth patterns in their investments.

• Smoothens volatility

CAGR masks the ups and downs experienced during the investment period by presenting a smoothed average return. This can be misleading for investors, as it hides periods of sharp declines or exceptional gains. As a result, it does not provide a complete picture of the investment’s risk or real-time behaviour.

• Not suitable for SIP or irregular cash flows

CAGR is designed for scenarios with a single investment and a single exit point. It does not account for multiple transactions like SIPs, withdrawals, or top-ups. For mutual fund investments involving regular or irregular cash flows, XIRR is a more accurate measure than CAGR.

CAGR Formula and Example

Use the following formula to calculate CAGR:

CAGR = [(End Value/Beginning Value) ^ (1/No. of years) - 1] x 100

Suppose you invested ₹50,000 in a mutual fund, and the value of your investment has grown to ₹1 lakh in 5 years. CAGR, in this case, would be 14.87%. There are online CAGR calculators that help you easily calculate CAGR.

XIRR vs CAGR for SIP Returns

XIRR provides a better measurement of SIP returns because it delivers more precise results than CAGR. SIP investments involve multiple instalments made on different dates, which CAGR cannot account for. The CAGR metric requires a single investment to be made at one time, and it does not consider investment timing.

XIRR evaluates all cash movements by considering their respective movement dates, which makes it the best metric to assess SIP performance.

Situations Where CAGR is the More Appropriate Method of Calculating Returns

The CAGR works most effectively when investments follow a basic structure that lasts for a specific duration without generating additional cash inflows. The system allows users to evaluate continuous compound growth during specific time frames while comparing various investment returns. In the following situations, CAGR works the best:

• You make a single lump-sum investment and withdraw it at a specific time.
• While comparing the long-term performance of mutual funds or stocks
• For fixed deposits, bonds, or instruments with a fixed investment period
• When analysing investments with steady growth and no intermediate cash flows

CAGR works best where timing variations do not impact returns.

XIRR vs CAGR for SIPs - Which Is Better?

As previously highlighted, CAGR shows the average annual growth and works well for a lump sum investment. Therefore, it doesn’t account for multiple cash flows. XIRR, on the other hand, factors in the timing and amount of each SIP instalment, giving a more accurate picture of returns. Thus, for evaluating SIP returns, XIRR is generally the better metric.

When XIRR Is More Useful Than CAGR – An Overview

For SIP investments: XIRR accounts for multiple instalments made at different times, unlike CAGR which assumes a one-time investment.

Irregular cash flows: If you invest or withdraw money at irregular intervals, XIRR gives a more accurate return than CAGR.

Multiple redemptions: When there are partial redemptions or withdrawals over time, XIRR captures the impact better.

Realistic return tracking: XIRR reflects actual investment behaviour, making it useful for tracking real-world returns in mutual funds or portfolio analysis.

When CAGR Is More Useful Than XIRR – An Overview

Lump sum investments: CAGR works best when the entire investment is made at once and held over a fixed period.

Simple return analysis: If you are looking for a straightforward measure of growth over time without multiple cash flows, CAGR is ideal.

Benchmark comparisons: It is commonly used to compare the long-term performance of mutual funds, stocks, or indices.

Consistent holding periods: When there are no additional investments or withdrawals, CAGR provides a clear picture of annual growth.

Conclusion

Depending on how you invest – whether through lump sum or systematic plans – you can choose between XIRR and CAGR to evaluate returns. Both metrics have their own strengths and limitations. CAGR offers a straightforward way to assess the growth of lump sum investments over time. However, if your investments involve multiple transactions, such as SIPs or redemptions at irregular intervals, XIRR provides a more accurate and comprehensive view.
