Sound investments breed profitable returns. Therefore, evaluating your return on investment (ROI) is critical, even when putting your money in the best long-term mutual funds. That said, the next important factor is to learn how to measure these returns accurately. ROI measurement entails calculating important metrics, especially XIRR (Extended Internal Rate of Return) and CAGR (Compound Annual Growth Rate). Both methods evaluate returns; however, each serves a unique purpose and is suitable for varying investment scenarios. This blog will help break down XIRR vs. CAGR so you can make informed investment decisions.
What is CAGR?
CAGR is the simple, clean average. CAGR tells you how much an investment has grown annually, assuming a steady, uninterrupted rate. It’s perfect for evaluating single investments over a fixed period.
Formula: CAGR = [(Final Value / Initial Value)^(1/n)] - 1
How to Calculate CAGR in Excel or Google Sheets
You don’t need to do the math manually—Excel or Google Sheets can handle it for you:

Example:
Imagine you invested ₹10,000 in a mutual fund five years ago. Today, the value is ₹20,000. The CAGR would be:
CAGR tells you that your investment grew at an annual rate of 14.87% over five years.
Key Features:
Ideal for one-time investments.
Assumes a single, lump-sum investment at the start.
You’re comparing the long-term performance of different funds with lump-sum investments.
Limitations of CAGR
Oversimplification: CAGR assumes uniform growth over time, disregarding market volatility and interim cash flows.
Lack of Real-World Applicability: In dynamic portfolios, investors frequently make additional investments or withdrawals, making CAGR an inadequate measure of actual returns.
What is XIRR
Real investments aren’t always so neat. You add money, withdraw funds, and reinvest dividends. That’s where XIRR comes in—it accounts for multiple cash flows and calculates the actual return based on when money moves in and out.
How to Calculate CAGR in Excel or Google Sheets
You can easily calculate CAGR in Excel or Google Sheets using the following formula:
=XIRR(cash flows, dates)
Let’s say you invest Rs 10,000, then add Rs 5,000 after a year, and withdraw Rs 3,000 later. CAGR won’t reflect this, but XIRR will. That’s why XIRR is the go-to metric for portfolios with irregular cash flows—real life, in other words.
Or
If you invest ₹10,000 every month for 12 months in a mutual fund and the fund’s value after a year is ₹130,000, XIRR takes into account the timing of each monthly investment and calculates the annualized return.
Limitations of XIRR
Principal Depletion Impact: XIRR may get tricky when the principal is redeemed from the total investment or when there is principal depletion, as it assumes the remaining capital continues to generate similar returns. This can distort performance evaluation, especially in drawdown scenarios.
Sensitivity to Input Data: Minor variations in cash flow dates can lead to significantly different results.
Comparability Issues: Unlike CAGR, which standardizes returns for comparison, XIRR varies based on investment timing, making direct comparisons challenging.

The Importance of XIRR and CAGR in Mutual Funds
When investors look for the best long-term mutual funds, they should understand the importance of XIRR and CAGR. Following are a few points that highlight how metrics like XIRR and CAGR help investors evaluate their returns:
SIP Investments: SIPs involve regular contributions over time. As a result, XIRR becomes the more accurate metric for calculating returns because it accounts for the timing and frequency of your investments.
Lump-Sum Investments: If you’re investing a lump sum in mutual funds, CAGR provides a clear picture of the fund’s annual growth rate.
Comparing Fund Performance: Both XIRR and CAGR allow you to compare the performance of mutual funds. Use CAGR to evaluate funds with stable, long-term growth and XIRR for SIP-based funds.
Return on Investment (ROI): A comprehensive understanding of these metrics helps you calculate the true ROI and make better financial decisions.
How to Use XIRR and CAGR Effectively
When you are unaware of your portfolio performance, then future investment decisions won't be well-informed. Therefore, evaluating investment performance is mandatory, especially when choosing the best long-term mutual funds. Here's how you can use XIRR and CAGR effectively to evaluate your returns:
1. Understand Your Investment Type
There are no one-size-fits-all metrics available to measure different investment types. For example, a one-time investment calls for CAGR asyour go-to metric. It provides a straightforward measure of your annualized returns over a specific period. On the other hand, SIPs made at multiple intervals require an XIRR metric, as it factors in the timing and amount of each cash flow.
2. Comparative Analysis
During the evaluation of mutual funds, you can choose one singular metric, either XIRR or CAGR, for a fair comparison. An inconsistent metric can lead to incorrect conclusions about which fund offers better returns. For instance, XIRR is more relevant for SIPs, while CAGR is ideal for lump-sum investments.
3. Leverage Technology
Manual calculations lead to potential errors that can be avoided by leveraging automated tools. Platforms like Cube Wealth offer ROI calculators to compute XIRR and CAGR effortlessly. These tools can simplify complex formulas to save you enough time and provide a precise return on investment value.
4. Consider Time Horizon
Both XIRR and CAGR yield meaningful insights over longer periods. They are valuable for assessing the best long-term mutual funds. During the evaluation of SIP investments or lump-sum mutual funds, a longer time horizon is needed to smooth market fluctuations and provide a clearer picture of performance.

FAQs
1. Why is XIRR used to calculate returns from SIP and not CAGR?
XIRR is used for SIPs because the principal invested keeps changing in a SIP, as you keep adding to your investments every month or week. In such cases, XIRR accurately accounts for several cash flows at regular or irregular intervals, which is characteristic of SIPs (Systematic Investment Plans), unlike CAGR.
2. Which is better, XIRR vs CAGR?
Honestly, both have their pros and cons. CAGR is inefficient when there is a change in the amount invested in between the periods, for example, an SIP or even if you keep investing and withdrawing ad-hoc in a mutual fund.
3. Which is better: CAGR or absolute return?
The choice depends on what you are looking to measure. Absolute returns do not take into consideration the period of investment. You should use absolute return when comparing short-term investments or when you simply want to know the total gain.
CAGR smooths out the growth rate over a period, showing how much your investment grew annually, assuming a steady rate.
Don’t be misled by absolute return. A 100% return sounds great, but over ten years, that’s just 7.18% CAGR.
Use CAGR for long-term planning. It helps in comparing different investments fairly.
Check both metrics. Absolute return tells you how much, and CAGR tells you how efficiently.
4. What XIRR is good?
This is a question that I frequently face from our users: is XIRR of 12% good or is 20% XIRR good? Honestly,It is difficult to answer this question. However, here are a few pointers that I use.
When I was starting this investment would I have been happy with 12% then?
Did I have other avenues where I could beat the returns I made aka Opportunity costs
But most importantly, returns are just one factor in evaluating your fund or portfolio’s performance. At Cube Wealth, we use more than 20 factors to evaluate a mutual fund. For example, what is the alpha (outperformance) of the fund, what is the period over which you are evaluating the performance, and how much risk did the fund take to deliver this return?

5. Are annualized returns and CAGR the same?
Annualized returns and Compound Annual Growth Rate (CAGR) are closely related, but they're not the same thing. Annualized returns represent the average return an investment has generated per year over a specific period. It smooths out the highs and lows, so you're essentially looking at what the return would have been if the investment performed at that rate every year. CAGR, on the other hand, is a more precise calculation. It measures the consistent, compounded rate of return that would have turned an initial investment into its final value over a set period. Unlike annualized returns, CAGR assumes that all gains are reinvested and grow at a constant rate year over year, regardless of any fluctuations in between. In simpler terms, while both deal with the yearly return, CAGR is a more accurate representation of an investment's growth over time because it accounts for the compounding effect. Annualized returns can sometimes be influenced by volatility or one-time events during the investment period.
6. Can we convert XIRR to CAGR?
To convert XIRR to CAGR, you essentially calculate the average annual growth rate assuming no further cash flows are made beyond the initial and final amounts, effectively “smoothing out” the variations in cash flows.
Let’s say you made an investment of ₹1,00,000 (initial value) in a mutual fund, and after 3 years, the value of your investment grew to ₹1,60,000. Assume that the XIRR of this investment, calculated based on irregular cash flows, was 15% annually.
To convert XIRR to CAGR, we can directly use the CAGR formula (since the cash flows are assumed to be similar to the constant annual growth implied by CAGR).
Initial Value = ₹1,00,000
Final Value = ₹1,60,000
Number of Years = 3
Now, using the CAGR formula:
So, in this example, the CAGR is approximately 16.9% per annum, which is a close match to the XIRR of 15% (considering that the cash flows in reality would have been irregular).
7. Are CAGR and XIRR the same?
No, CAGR (Compound Annual Growth Rate) and XIRR (Extended Internal Rate of Return) are related but not the same. CAGR measures the average annual growth rate of an investment assuming a consistent growth rate over a period. It’s useful for steady investments. XIRR, on the other hand, accounts for irregular cash flows and provides a rate of return that balances those varying inflows and outflows over time. For example, if you invest ₹1,00,000 and withdraw ₹10,000 at irregular intervals, XIRR reflects that complexity, while CAGR assumes the investment grows at a constant rate.
8. What is the difference between CAGR and the absolute return formula?
Think of CAGR as the smooth, steady growth of your money over time. It tells you what your average yearly return would be if your investment grew at the same rate every year. For example, if you invested ₹10,000 and after 5 years it became ₹20,000, CAGR would tell you the constant yearly growth that led to that result.
On the other hand, absolute return just tells you how much your money grew in total. If your ₹10,000 turned into ₹20,000, the absolute return is ₹10,000, with no focus on how the money grew year by year.
