XIRR in mutual funds is a method used to calculate the annualised return on investments that involve multiple and irregular cash flows, such as SIPs (Systematic Investment Plans), lump sum investments, and partial redemptions.
Unlike simple return metrics, XIRR accounts for both the timing and amount of each transaction, making it highly accurate for real-world mutual fund investments. It helps investors understand how their money has grown over time, factoring in every inflow and outflow.

XIRR Meaning and Full Form
Extended Internal Rate of Return (XIRR) is a method used to calculate the annualised return on investments when there are multiple transactions occurring at irregular intervals, such as SIPs, lump-sum top-ups, or partial redemptions.
XIRR takes into account both the amount and the exact date of each cash flow, giving a more accurate picture of real returns. It is widely used in mutual fund investments because most investors don’t invest or withdraw money in a single transaction. Instead, they:
- Invest through SIPs
- Make ad-hoc lump sum contributions
- Redeem partially at different times
XIRR helps calculate the true annual return for such irregular cash flows by accounting for the time value of money. This makes it the most suitable return metric for tracking actual investor performance over time.
How XIRR is Different from CAGR
While both XIRR and compound annual growth rate (CAGR) measure returns, they differ significantly:
| Feature | XIRR | CAGR |
| Full Form | Extended Internal Rate of Return | Compound Annual Growth Rate |
| Cash Flow Type | Irregular (multiple inflows/outflows) | Single investment and redemption |
| Date Sensitivity | Considers exact transaction dates | Assumes a fixed time period |
| Use Case | SIPs, partial redemptions, top-ups | Lump sum investment with no cash flow changes |
| Accuracy | More precise for mutual fund portfolios | Suitable for simple investment growth |
How XIRR Works in Mutual Fund Investments
XIRR helps you calculate the actual annualised return on mutual fund investments when the cash flows (investments and redemptions) happen at irregular intervals. Unlike simple return metrics, XIRR captures the impact of both amounts invested and dates of transactions, making it ideal for SIPs or staggered contributions.
How XIRR Calculates Returns on SIPs
In SIPs, you invest fixed amounts at regular intervals—say monthly—but the market value (NAV) changes each time. XIRR calculates the annualised return by considering each SIP investment as a separate cash flow and the final redemption value as the outcome.
It then computes a single percentage that answers:
“At what annual rate did my money grow, given the timing and size of each investment?”
This is especially useful because CAGR doesn’t account for multiple investments over time; it only works with a single inflow and outflow.
Role of Dates and Amounts in XIRR Formula
XIRR considers two critical inputs:
- The exact date of each transaction: This allows it to weigh investments that stayed longer in the fund more heavily.
- The amount of each investment or withdrawal: This helps reflect the real return based on actual money movement.
For example:
- ₹5,000 invested in Jan 2022
- ₹5,000 invested in June 2022
- ₹12,000 redeemed in May 2023
XIRR uses these amounts and dates to calculate the return that links these cash flows. A difference of just a few days in the transaction date can change the XIRR value, especially for short investment durations.

Examples of XIRR in Action
Let’s say that you invested ₹5,000 on the 1st of every month from Jan to Dec 2024. The fund grows steadily and reaches a total value of ₹70,000 by Dec 2024. In this case, using Excel, we would get an XIRR of 11.5%.
Similarly, in the case of irregular investments such as:
- ₹10,000 invested on 1 Jan 2024
- ₹15,000 invested on 15 Apr 2024
- ₹30,000 redeemed on 1 Jan 2025
The XIRR would be 13.7%, higher than the CAGR because of earlier growth and larger late investment.
What is a Good XIRR in a Mutual Fund?
A good XIRR in mutual fund investments depends on your financial goals, risk tolerance, and investment horizon. As a rule of thumb, any XIRR that exceeds the inflation rate is considered satisfactory since it indicates real wealth creation.
Generally, an XIRR of 12% or more is considered good for equity mutual funds, especially if it consistently outperforms the fund’s benchmark or similar funds in its category. In the case of debt mutual funds, a good XIRR is typically around 7.5% or higher.
However, these values can vary:
- A moderate-risk equity fund with a 7–9% XIRR may still be acceptable if inflation is low.
- An aggressive small-cap fund might be expected to deliver 12–15%.
- A conservative debt fund could target 5–6% depending on market cycles.
Ultimately, a good XIRR beats average market returns and aligns with your investment goals while maintaining consistency relative to benchmark indices and peer funds.
When and Why to Use XIRR
XIRR is a useful metric when you’re dealing with multiple, irregular investments, such as Systematic Investment Plans (SIPs), partial withdrawals, or ad-hoc top-ups in mutual funds. It helps you calculate the annualised rate of return, considering both the amount and the exact timing of each cash flow. Here’s how and when to use XIRR effectively:
XIRR vs Absolute Return: Which is Better?
Absolute return simply calculates the percentage gain or loss on your investment without considering time. It works well when you invest a lump sum and redeem once, over a short and clearly defined period.
XIRR, on the other hand, is better suited when:
- Your investments happen over months or years.
- Cash flows are irregular.
- You want to compare performance across different investment durations.
For example, if you invested ₹10,000 over several months and ended with ₹12,000, the absolute return is 20%. But XIRR may show 10.5% annually, which gives more context, especially for comparing with other funds or benchmarks.
When to Use XIRR for Tracking Your Portfolio
Use XIRR when:
- You’re reviewing mutual fund SIPs with monthly or irregular contributions.
- You’ve made multiple lump sum investments in the same scheme over time.
- You want to calculate returns from partial withdrawals or redemptions.
- You need a standardised return metric for comparing performance across multiple funds.
It’s especially valuable when you’re investing over different time horizons and want a consistent, time-adjusted return measure that accounts for compounding and timing.
Tools to Calculate XIRR (Excel, Online Calculators)
Some tools that you can use to calculate XIRR are:
Excel or Google Sheets
- List all your cash flows:
- Investments as negative numbers
- Withdrawals/redemptions as positive
- Add corresponding transaction dates
- Use the formula:
=XIRR(values, dates)
Excel gives the annualised return immediately, even if your investment spans months or years.
Online Mutual Fund XIRR Calculators
These require you to input:
- Investment dates and amounts
- Redemption date and value
And that’ it! You’ll have your data in seconds. These are ideal if you don’t want to track cash flows manually.
Limitations of XIRR
Relying solely on XIRR without context can lead to misleading conclusions, especially if your investment history or market conditions are complex. Here’s a deeper look at key limitations:
Factors That Can Distort XIRR
So important factors that distort XIRR are:
- Lump Sum Redemptions or Inflows Near the End: If a large investment or redemption occurs close to the end of the investment period, XIRR can get heavily skewed. For instance, a large redemption just before calculating XIRR can make the returns look extremely high or low, even if it doesn’t reflect the overall portfolio performance.
- Timing Sensitivity: XIRR is highly sensitive to the exact dates of each cash flow. A transaction made at the end of a month vs the beginning can create a notable difference in the output, especially when dealing with short investment periods or volatile funds.
- Assumption of Reinvestment at the Same Rate: XIRR assumes that interim cash flows (especially redemptions) are reinvested at the same rate of return. In practice, this rarely happens, which makes the actual realised return lower than what XIRR might suggest.
- Unrealistic Outlier Results in Short Durations: In cases where the investment duration is very short (a few days or weeks), XIRR can show inflated or negative values that don’t reflect long-term trends. For example, a ₹1,000 investment that grows to ₹1,050 in 10 days may show an XIRR of 900% +, which is technically correct but practically irrelevant.
Importance of Consistent Investment Tracking
XIRR is highly sensitive to how well your transactions are tracked:
- Missed Dates or Incorrect Cash Flow Entries: If you input the wrong date or amount for even a single SIP or redemption, the XIRR can deviate significantly from the actual return.
- Switches Between Funds: If you switch from one mutual fund scheme to another but treat them as one continuous investment in XIRR, it distorts results. Each switch ideally requires a new XIRR trail.
- Offline and Online Investments Not Merged: Many investors use different platforms. If transactions across them aren’t combined and recorded properly, your XIRR calculation will be incomplete or misleading.
XIRR Is Not Always a Predictor of Future Returns
XIRR reflects past performance based on historical cash flows. It does not account for:
- Future market volatility
- Changing fund performance
- Economic and interest rate cycles
Just because a mutual fund delivered a 15% XIRR over the past 3 years doesn’t mean it will do the same in the future. Investors often mistake high past XIRRs as a guarantee of future returns, leading to unrealistic expectations. Moreover, XIRR doesn’t factor in risk, so a high XIRR might come from a highly volatile fund unsuitable for conservative investors.
Conclusion
In mutual fund investing, XIRR is the most practical and precise way to track performance, especially when your investments don’t follow a fixed pattern. Whether you’re investing monthly through SIPs or making top-ups at different times, XIRR provides a clear, time-adjusted view of your annual returns. This helps you make better decisions and compare fund performance meaningfully.
FAQs
What is XIRR, and how is it calculated in mutual funds?
XIRR (Extended Internal Rate of Return) is a method used to calculate the annualised return on mutual fund investments when the cash flows (investments and withdrawals) happen at irregular intervals. It accounts for the exact timing of each transaction, unlike CAGR, which assumes uniform investment. To calculate XIRR, you need the date and amount of each cash flow—tools like Excel or online XIRR calculators do this automatically.
What is considered a good XIRR in mutual fund investments?
Typically, a good XIRR in mutual fund investments means:
- 7%–10% for equity mutual funds.
- 4%–6% above inflation for debt funds.
This varies based on market cycles, risk tolerance, and investment horizon. In general, what is best XIRR in mutual fund investing is one that beats inflation and aligns with your financial planning.
How is XIRR different from CAGR and IRR?
XIRR is best for mutual funds with multiple, irregular cash flows. CAGR (Compound Annual Growth Rate) only reflects the average growth rate, assuming one lump sum invested and redeemed once. IRR (Internal Rate of Return) is used more for project-based investments. So, for SIPs or multiple redemptions, XIRR offers the most accurate reflection of real returns.
Can XIRR be negative in mutual fund investments?
Yes. If your mutual fund’s current value is lower than your total invested amount, XIRR will show a negative return. This often happens when markets decline after you invest or if you withdraw early during a market correction.
How to calculate XIRR using Excel or online tools?
To calculate XIRR in Excel, simply enter your investment and redemption amounts (with withdrawals as positive and investments as negative) along with corresponding dates. Then use the formula, ‘=XIRR(values, dates).’ Similarly, to calculate XIRR using online tools, input your cash flows and dates into any trusted mutual fund XIRR calculator.
