Question

1. K. Herrmann has decided to set up a scholarship fund for students. She is willing to deposit $5,000 in a trust fund at the end of each year for 10 years.                    She wants the trust fund to then pay annual scholarships at the end of each year for 30 years.                 

                    2. Charles Jordy is planning to save for his retirement. He has decided that he can save $3,000 at the end of each year for the next 10 years, $5,000 at the                    end of each year for Years 11 through 20, and $10,000 at the end of each year for Years 21 through 30.                 

                    3. Patricia Karpas has $200,000 in savings on the day she retires. She intends to spend $2,000 per month traveling around the world for the next 2 years,                    during which time her savings will earn 18%, compounded monthly. For the next 5 years, she intends to spend $6,000 every 6 months, during which time her                    savings will earn 12%, compounded semiannually. For the rest of her life expectancy of 15 years, she wants an annuity to cover her living costs. During this                    period, her savings will earn 10% compounded annually. Assume that all payments occur at the end of each period.                 

                    Required:                 

                    1. In Situation 1, how much will the annual scholarships be if the fund can earn 6%? How much at 10%?                 

                    2. In Situation 2,                 

                    (a) How much will Charles have at the end of 30 years if his savings can earn 10%? How much at 6%?                 

                    (b) If Charles expects to live for 20 years in retirement, how much can he withdraw from his savings at the end of each year if his savings earn 10%? How much                    at 6%?                 

                    (c) How much would Charles need to invest today to have the same amount available at the time he retires as calculated in Situation 2(a) at 10%? How much at                    6%?                 

                    3. In Situation 3, how much will Patricias annuity be?

Explanation / Answer

N is number of periods

r= rate of interest

PMT=payment

FV=future value

PV=present value.



1) r=6%

for first 10 years

r=6% N =10 PMT=5000 PV=

SO FV=65904

For next 30 years

N=30 I =6% PV=65904 FV=0

So PMT 4788

so scholarship will be $4788/year

##############

if r=10%

for first 10 years

r=10% N =10 PMT=5000 PV=

SO FV=$79687

For next 30 years

N=30 I =6% PV=$79687 FV=0

So PMT 8453

so scholarship will be $8453/year


2)a) for 10 years= saving $3000/year

for next 10 year $5,000

for next 10 year $10,000

taking r=10%

for first 10 year

N=10 r=10 PMT=3000 PV=0

so FV=47812

FOr next 10 year

N=10 r=10 PMT=5000 PV=47812

so FV=203700

for next 10 year

N=10 r=10 PMT=10000 PV=203700

so FV=$687720 at the end of 30 years

##############

taking r=6%

for first 10 year

N=10 r=6 PMT=3000 PV=0

so FV=39542

FOr next 10 year

N=10 r=6 PMT=5000 PV=39542

so FV=136717

for next 10 year

N=10 r=6 PMT=10000 PV=136717

so FV=$376647 at the end of 30 years

....................

b)for 20 years on retirement

if r=10%

N=20 r=10 PV=687720 FV=0

so PMT=$80780/year

#############

if r=6%

N=20 r=6 PV=376647 FV=0

so PMT=$32837/year

..............

c)

for =10%

N=30 r=10 FV=687720 PMT=0

so PV=$394122 to be deposted at today

#########

for r=6%

N=30 r=6% FV=$376647 PMT=0

so PV=$65578 to be deposted at today


3)for next two year

PV=$200,000

spending= $2,000 per month

and r=18% compunded monthly

so N=2*12

r=18/12 % monthly

so N=24 r=1.5 PMT= -2000 PV=20000

so FV=$228633.5

for next 5 years

spend $6,000 every 6 months, r= 12% componded semi-semiannually.

so N=2*5 r=12/2 % and PMT=- $ 6000

PV=$228633.5 so

FV=$330362


for next 15 years

N=10 r=10% PV=$330362 FV=0


so PMT=$53765

so annuity be $$53765 per year
