Using the RRI function

The RRI function returns an equivalent interest rate for the growth of an investment. For example, to use RRI to calculate equivalent annual compound interest for a 1000 investment worth 1200 after five years you can use a formula like this:

=RRI(5,1000,1200) // returns 0.037137289

In the example shown, the formula in G6 is:

=RRI(B11,C6,C11)
