You want to have $1,000,000 when you retire in 30 years. You expect to earn 12% compounded monthly over the entire 30-year period. How much extra money per month must you deposit if you choose to fund using an ordinary annuity technique rather than an annuity due technique?
- Future Value in 30 years in retirement = $1,000,000
Calculating the monthly periodic deposit using FV of ordinary annuity formula:-
Where, C= Periodic Deposits
r = Periodic Interest rate = 12%/12 = 1%
n= no of periods = 30 years*12 = 360
Future Value = $1,000,000
C = $286.13
So, Monthly deposit in ordinary annuity is $286.13
- Calculating the monthly periodic deposit using FV of annuity due formula:-
Where, C= Periodic Deposits
r = Periodic Interest rate = 12%/12 = 1%
n= no of periods = 30 years*12 = 360
Future Value = $1,000,000
C = $283.29
So, Monthly deposit in annuity due is $283.29
- So, extra money per month must you deposit if you choose to fund using an ordinary annuity technique rather than an annuity due technique = $286.13 - $283.29
= $2.84
