XIRR (Extended Internal Rate of Return) calculates an annualized rate of return, not a cumulative one, but it does so by considering the exact timing and amounts of irregular cash flows (investments/withdrawals) over a specific period, making it a more accurate measure of your actual investment performance than simple cumulative returns. It essentially finds the single rate that makes the net present value of all your transactions zero, expressed as a yearly percentage.
Incorporating Systematic Investments
For investors practising SIP Investment where contributions are made regularly, XIRR offers a reliable method to calculate the annualised return, considering the staggered nature of investments.
The fact that XIRR can generate daily results does not mean it compounds daily; in fact, XIRR compounds annually, but it simply has the ability to provide results based on inputs from any given day. The underlying formula that XIRR utilizes is as follows: (1+R)^(#days/365)-1.
XIRR allows cash flows to occur on any date, with values that may vary and represent either income (positive) or expenditure (negative). At least one value must be negative and at least one value must be positive. XIRR assumes that all years (including leap years) comprise 365 days.
XIRR is an annualized type of return, whereas the annualized return signifies what investment will be returned over some time when the annual return is compounded.
The meaning of XIRR in mutual fund investments refers to the 'Extended Internal Rate of Return,' - a financial metric that calculates the annualised return on investments involving multiple cash flows occurring at irregular intervals.
In simpler terms, IRR tells you the rate of return an investment is expected to generate over its lifetime. For example, if a project has an IRR of 15%, it means that the project is expected to generate an annual return of 15% on the invested capital, provided that assumptions about cash flows hold .
Difficult to interpret for short-term investments
XIRR can produce misleading or exaggerated results when applied to very short-term investments with limited transactions.
One thing to keep in mind as you watch is that the =XIRR() formula annualizes the IRR, whereas the =IRR() formula will return the rate of return for the period (month, quarter, year, etc.). In other words, if you measure the IRR for one month using the =IRR() formula the function will return the IRR for that month.
Compared to annual compounding, monthly compounding provides higher returns. This is because interest is added to the principal twelve times a year, helping your funds to grow quicker.
"12% interest" means that the interest rate is 12% per year, compounded annually. "12% interest compounded monthly" means that the interest rate is 12% per year (not 12% per month), compounded monthly. Thus the interest rate is 1% (12% / 12 ) per month.
Is XIRR compounded monthly? XIRR is not inherently compounded monthly. It represents an annualised rate of return that considers all cash flows' timing and amounts, regardless of whether they occur monthly, quarterly, or at any other interval.
XIRR stands for Extended Internal Rate of Return. In contrast to IRR, the XIRR formula provides you with an extended rate of return that takes into account cash flows and discount rates, as well as the corresponding dates, providing you with a more accurate ROI percentage.
Generally, an XIRR of 12% is considered good for equity mutual funds, while in the case of debt funds, it is 7.5%. Is XIRR better than CAGR? It depends on the investment type for which you are calculating the return. XIRR is better when there are irregular cash flows in the investment, such as SIPs in mutual funds.
XIRR provides an annualised rate of return that considers the timing and amount of each cash flow. In contrast, absolute return measures the total return without regard to the investment period or cash flow timings.
XIRR Formula
The formula takes into account both the magnitude and timing of the cash flows, and calculates the rate at which the net present value of the cash flows is zero. The XIRR formula requires two arguments: A range of cash flows which represents the amount of money received or paid out at each date.
The problem? Excel's built-in XIRR function expects the first value in its range to be negative. So, if the first cell (or the first several cells) are zero, XIRR will always return 0.00%, even if cash flows materialize later.
Assume Excel returns an XIRR of 15%. It means your investment in the mutual fund has generated an annualized return of 15%, considering all contributions, dividends, and the final investment value.
How to Calculate XIRR Manually?
The return generated by XIRR is an annualized return (over the period defined by the dates).
The best way to calculate your return is to use the Excel XIRR function (also available with other spreadsheets like Google Sheets and financial calculators). This gives you a dollar-weighted return because it takes into account the timing and amount of your cash flows into and out of your retirement funds.
A 10% annualized total return might be considered good by some investors, while others would prefer to see a higher rate. It depends on your investing goals, timeframe, and strategy.
