An individual wants to accumulate $750,000 for retirement in 30 years. She wants to make yearly deposits into an account which earns 8% annually. Determine the size of the payments needed if the payments are made at: A: the end of the year. ($6620.58) B: the beginning of each year. ($6130.16) Cannot use Excel.
Required Future Value to accumulate (FV)= 750000
Interest rate (I)= 8%
Number of years (n)= 30
A.
Payment is to be made at end of Year, so it is ordinary Annuity.
Amount required to save each period at end (ordinary Annuity) to accumulate Future Value Formula = Future value*i/(((1+i)^n)-1)
=750000*8%/(((1+8%)^30)-1)
=6620.57504
So Amount Required to save each year at end is $6620.58
B.
Payment is to be made at Beginning of Year, so it is Annuity due.
Amount required to save each period at Beginning (Annuity due) to accumulate Future Value Formula = Future value*i/((((1+i)^n)-1)*(1+i))
=750000*8%/((((1+8%)^30)-1)*(1+8%))
=6130.162074
So Amount Required to save each year at Beginning is $6130.16
