Expert's answer

a)Since he wants to become a millionaire, the current present value will be 1,000,000. You need to find monthly savings to accumulate a million at the following intervals

PVA=1 000 000

a) According to the annuity formula:

"PVA=A(\\frac{(1+\\frac{i}{m})^{mn}-1}{\\frac{i}{m}})"

"1 000 000=A(\\frac{(1+\\frac{0.119}{12})^{480}-1}{\\frac{0.119}{12}})"

n=40,m=12, mn=480

A=87,73

b) "1 000 000=A(\\frac{(1+\\frac{0.119}{12})^{300}-1}{\\frac{0.119}{12}})"

40-15=25

n=25,m=12, mn=300

A=541.76

c)"1 000 000=A(\\frac{(1+\\frac{0.119}{12})^{180}-1}{\\frac{0.119}{12}})"

40-25=15

n=15,m=12, mn=180

A=2020.75
