1, the expected annualized rate of return is calculated according to the same income every month.

2. If you invest at the beginning of each month, you can achieve the expected return in that month.

Calculation:

1, calculate the monthly rate of return q, q = (r+1) (112).

2. calculate a 1. According to the investment in the last month of the nth year, a1= y * (1+q) = y * [(r+1) (1/2)].

3. According to the summation formula of proportional series, Fv = a1* (1-q (12n))/(1-q) =1... = y * (r+/kloc-0
