Two friends, Alysha and Laura, are planning for their
retirement. Both are 20 years old and plan on retiring in 40 years
with $1,000,000 each. Laura plans on making annual deposits
beginning in one year (total of 40 deposits) while Alysha plans on
waiting and then depositing twice as much as Laura deposits.
If both can earn 7.4 percent per year, how long can Alysha wait
before she has to start making her deposits? (Round
answer to 2 decimal places, e.g. 125. Do not round your
intermediate calculations.)
First find the annuity amount for Laura
Future Value of annuity = A* ((1+rate)^n-1)/rate
1000000= A*((1+7.4%)^20-1)/7.4%
1000000= A*42.83129503
A= 23347.41
Annuity amount for Alysha= 2*23347.41= $46,694.83
In financial calculator enter
FV=1000000
PMT=-$46,694.83
I/Y=7.4
Solve for N as 13.30 years
Number of years Alysha can wait= 20-13.30 = 6.70 years
