A compound annual growth rate (CAGR) measures the rate of return for an investment — such as a mutual fund or bond — over an investment period, such as 5 or 10 years. The CAGR is also called a "smoothed" rate of return because it measures the growth of an investment as if it had grown at a steady rate on an annually compounded basis. To calculate CAGR, use the XIRR function.
Example
Note
When you compare the CAGRs of different investments, make sure that each rate is calculated over the same investment period.
