Question

Solving for rates what annual rate of return is earned on a $2,800 investment when it grows to $6,100 in eleven years?

Answer 1

To solve use equation:
FVn = 6100 - investment amount after 11 years
PV = 2800 - initial investment amount
n = number of years

Fvn = Pv(1+i)^n
6100 = 2800(1+i)^11
(1+i)^11 = 6100/2800
(1+1)^11 = 2.17857143
i = (2.17857143)^(1/11)-1
i = 0.07335
i = 0.07335 x 100
i = 7.34%

The annual rate of return is 7.34%
