## RRI formula syntax

The RRI function in Excel calculates the compound annual growth rate (CAGR) of an investment based on a series of cash flows. Its syntax is: RRI(nper, pmt, pv, fv) - nper: The total number of periods for the investment. - pmt: The periodic payment or cash flow. - pv: The present value or initial investment amount. - fv: The future value or desired ending investment amount. The RRI function returns the annualized rate of return as a decimal. It can be used to compare different investment options or evaluate the performance of an investment over time.
