You can put this solution on YOUR website!
A = P ( 1 + r/n )^nt
P = principal amount (initial investment)
r = annual interest rate (as a decimal)
n = number of times the interest is compounded per year
t = number of years
A = amount after time t
1000000 = 50000 ( 1 + .18/12 )^12t
t = 16.7675
add that to 18
34.7675
