Answer 1

in 65 years:

$1000*\frac{(1+0.12/12)*((1+0.12/12)^{(65-12)*12}-1}{1.01-1}=56,485,795.36$

40-year-old:

$1000*\frac{(1+0.12/12)*((1+0.12/12)^{(65-40)*12}-1}{1.01-1}=1,897,635.09$ - will get

needs to invest per month:

$56,485,795.36-1,897,635.09=54,588,160.27$

$54,588,160.27/\frac{(1+0.12/12)*((1+0.12/12)^{(65-40)*12}-1}{1.01-1}=29,054.08$
