Yes, the XIRR function in Excel is always annualized. It calculates the internal rate of return for a series of cash flows with irregular dates, assuming a 365-day year. The resulting percentage represents the annualized effective return rate.
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.
XIRR helps you calculate annualised returns on investments when you have made multiple transactions at different times, particularly for Systematic Investment Plans (SIPs).
What is the XIRR Function? The XIRR Function[1] is categorized under Excel financial functions. It will calculate the Internal Rate of Return (IRR) for a series of cash flows that may not be periodic. It does this by assigning specific dates to each individual cash flow.
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 .
The XIRR calculation considers the size and timing of cash flows. It finds the discount rate that makes the present value of all cash flows (both positive and negative) equal to zero. The resulting rate is then annualised to provide a percentage representing the annual return rate.
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.
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.
Dynamic XIRR can be achieved with a combination of functions including MATCH, INDEX, ADDRESS and INDIRECT. It is dynamic because if the first negative cash flow changes, so will the XIRR inputs. It can therefore be replicated with copy and paste.
As we've explained, the key difference between IRR and XIRR is the way each formula handles cash flows. IRR doesn't take into account when the actual cash flow takes place, so it rolls them up into annual periods. By contrast, the XIRR formula considers the dates when the cash flow actually happens.
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.
It is suitable for lump sum investments with no interim transactions. XIRR is used in scenarios with multiple transactions, such as SIP or staggered investments. It considers the amount and timing of each cash flow, providing an annualised return that reflects the overall investment experience.
XIRR is considered a more precise and accurate measure of returns on investment, which are irregular compared to other financial metrics like CAGR and SAR. XIRR considers the dates on which transactions and cash flows occurred, making it a more accurate measure of an investment's annual performance.
The formula for XIRR is: XIRR = (NPV of Cash Flows / Initial Investment) × 100. The ideal XIRR varies based on the type of fund and individual financial goals. For example, a conservative debt fund might target an XIRR of 5–6%, while an aggressive small-cap fund may aim for 12–15%.
Step by Step Process to Calculate in Excel
The XIRR function yields the implied internal rate of return (IRR) given a schedule of cash inflows and outflows. But unique to the XIRR function, the cash flows are NOT necessarily required to be periodic, i.e. the dates at which the cash flows occur can be irregular with regard to timing.
In most cases you do not need to provide guess for the XIRR calculation. If omitted, guess is assumed to be 0.1 (10 percent). XIRR is closely related to XNPV, the net present value function. The rate of return calculated by XIRR is the interest rate corresponding to XNPV = 0.
XIRR determines the yearly return rate by calculating the total value of all money invested and the total value of all money withdrawn based on their dates and adjusting the return rate until both sides balance.
How much XIRR to double in 3 years? To double your investment in 3 years, you need an approximate XIRR of 24% per annum as per the Rule of 72. 72 divided by the number of years (72/3 = 24).
The following is the process for calculating SIP returns in MS Excel:
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 Limitations
XIRR calculations rely on the accuracy and completeness of cash flow estimates. Any inaccuracies in these estimates can significantly affect the XIRR calculation and produce misleading results. It assumes that cash flows are reinvested at the same rate as the calculated XIRR.
Use IRR for projects or investments with regular cash flows, such as annual business payments. Use XIRR for investments with differing dates or timing, such as SIPs, real estate, or staggered transactions. If timing is uncertain, XIRR may provide a more realistic picture of performance.
