Question 15
Susan saved $5000 per year in her retirement account for 10 years (during age 25-35) and then quit saving. However, she did not make any withdrawal until she turned 65 (i.e., 30 years after she stopped saving). Her twin sister, Jane did not save anything during the 1st 10 years (during age 25-30) but saved $5,000 per year for 30 years (during age 35-65). What will be the difference in their retirement account balance at age 65, if their investments earned an average return of 7.5% during the entire period?

Present Value of the villa = PV = $500000
Inflation rate = i = 5.5%
Number of years = n = 15
Future Value of Villa = FV = PV(1+i)n = 500000(1+0.055)15 = $1116238.25
Let the lumpsum deposited today be P
Interest rate earned = r = 10%
Future Value required = FV = $1116238.25
=> P(1+r)n = 1116238.25
=> P(1+0.10)15 = 1116238.25
=> P = 1116238.25/(1+0.10)15 = $267219

Susan
Amount deposited each year = P = $5000
Number of years = n = 10
Interest Rate = r = 7.5%
Value in Account after 10 years X = P(1+r)n-1 +....+ P(1+r)2 + P(1+r) + P = P[(1+r)n -1]/r = 5000[(1+0.075)10 -1]/0.075 = $70735.44
Value of X after 30 years = X(1+r)30 = 70735.44(1+0.075)30 = $619285.61
Jane
Amount saved each year = P = 5000
Number of years = n = 30
Interest rate = r = 7.5%
Amount in account after 30 years = P(1+r)n-1 +....+ P(1+r)2 + P(1+r) + P = P[(1+r)n -1]/r = 5000[(1+0.075)30 -1]/0.075 = $516997.01
Difference in amount = 619285.61 - 516997.01 = $102289
