You put aside $300 a month in an account that returns 9% a year, compounded monthly. how long do you need to contribute to save $1,000,000

36 years 4 months and 2 days

Explanation:

Data provided in the question:

Monthly payment = $300

Rate of return, i = 9% = 0.09

Future value = $1,000,000

Now,

we know

Future value = Monthly payments ×

or

1000000  = $300 ×

or

or

1.0075ⁿ - 1 = 25

or

1.0075ⁿ = 26

ln( 1.0075ⁿ) = ln(26)

or

n × ln( 1.0075 ) = ln(26)

or

n = [tex]\frac{ \ln (26) }{ \ln( 1.0075 ) }[tex]

or

n = 436.04  months

or

n = 36 years 4 months and 2 days

436 months or 36.33 years

Explanation:

monthly principal P = $300

Amount to be obtained A = $1,000,000

ROI per annum R% = 9%

or ROI per month r% = 9/12 = 0.75%

and n = no. of months

We know that

plugging values we get

solving the above equation we get

n = 436 months

which is equal to 36.33 years.
