**IRR (Internal Rate of Return)**

**What it Measures:** IRR calculates the annual rate of return for investments where cash flows regular or we can say that they are expected to be consistent over time.

**Use Case: **It’s typically used for evaluating the profitability of investments or projects where cash inflows and outflows are evenly spaced over time, like equal annual payments.

**Calculation Method: **IRR assumes that all cash flows are reinvested at the same rate as the IRR itself.

**Limitation:** Doesn’t accurately reflect the return for investments with irregular cash flows or varying reinvestment rates and so this is not always practical measure for annualized returns.

**XIRR (Extended Internal Rate of Return)**

**What it Measures:** XIRR is a more generalized version of IRR, designed to handle investments with cash flows that are not periodic.

**Use Case:** Ideal for calculating returns on investments like stocks, mutual funds, or any scenario where investments or withdrawals occur at irregular intervals.

**Calculation Method**: It takes into account the exact dates of each cash flow, making it more precise for irregular investments.

**Advantage**: Provides a more accurate reflection of the annualized return for investments with irregular or random cash flows.

Example: Returns on Stocks or Mutual Funds, or even your overall portfolio returns.

**CAGR (Compound Annual Growth Rate)**

**What it Measures:** CAGR calculates the mean annual growth rate of an investment over a specified time period longer than one year.

** Use Case: **Useful for comparing the growth rates of investments over time. It’s often used to** understand the growth of a single investment** or to compare the historical returns of different investments.

**Calculation Method:** It assumes that the investment grows at a steady rate over the period. The formula is

**Limitation: **Oversimplifies performance as it doesn’t account for volatility or fluctuating cash flows within the period.

Example: Can be used to measure annualized return of investment on Real estate, any Single large investment (Stocks, Fund, Crypto) etc.

**In Summary:**

– IRR is best for periodic cash flows.

– XIRR is ideal for irregular cash flows, giving a more accurate picture of real-world scenarios.

– CAGR is great for a simplified, average annual growth rate, ignoring intermediate fluctuations.

Each metric has its ideal context and offers a unique perspective on investment performance.
