Steve and Ed are cousins who were both born on the same day, and both both turned 25 today. Their grandfather began putting $2,500 per year into a trust fund for Steve on his 20th birthday, and he just made a 6th payment into the fund. The grandfather (or his estate's trustee) will make 40 more $2,500 payments until a 46th and final payment is made on Steve's 65th brithday. The grandfather set things up this way because he wants Steve to work, not to be a "trust fund baby," but he also wants to ensure that Steve si provided for in his old age.
Until now, the grandfather has been disappointed with Ed, hence has not given him anything. However, they recently reconciled, and the grandfather decided to make an equivalent provision for Ed. He will make the first payment to a trust for Ed today, and he has instructed his trustee to make 40 additional equal annual payment until Ed turns 65, when the 41st and final payment will be made. If both trusts earn annual return of 8%, how much must the grandfather put into Ed's trust today and each subsequent year to enable him to have the same retirement nest egg as Steve after the last payment is made on their 65th birthdat?
a. $3,726
b. $3,912
c. $4,107
d. $4,313
e. $4,528
3,726
To determine how much the grandfather must put into Ed's trust today and each subsequent year, we need to find the equivalent contributions to ensure that Ed will have the same retirement nest egg as Steve after the last payment is made on their 65th birthday.
Let's start by calculating the future value of Steve's trust fund. We know that the grandfather made 6 payments of $2,500 each, so there are 46 - 6 = 40 payments left. The payments occur annually, and the interest rate is 8%.
Using the future value of an ordinary annuity formula, we can calculate the future value of Steve's trust fund:
FV = P * [(1 + r)^n - 1] / r
Where FV is the future value of the annuity, P is the annual payment, r is the interest rate, and n is the number of payments.
In this case, P = $2,500, r = 0.08, and n = 40.
FV = $2,500 * [(1 + 0.08)^40 - 1] / 0.08
FV ≈ $254,721.38
So, the future value of Steve's trust fund will be approximately $254,721.38.
Now, we need to calculate the amount that the grandfather must contribute to Ed's trust fund to achieve the same future value.
Using the future value of an ordinary annuity formula again, but this time solving for the payment amount, we have:
P = FV * (r / [(1 + r)^n - 1])
Where P is the payment amount, FV is the future value of the annuity, r is the interest rate, and n is the number of payments.
In this case, FV = $254,721.38, r = 0.08, and n = 41 (41 payments including the first payment).
P = $254,721.38 * (0.08 / [(1 + 0.08)^41 - 1])
P ≈ $3,911.87
So, the amount that the grandfather must contribute to Ed's trust fund today and each subsequent year is approximately $3,911.87.
Therefore, the answer is b. $3,912.
To calculate the amount that the grandfather must put into Ed's trust, we can use the present value formula for an annuity. The present value (PV) of an annuity is the value of all the future cash flows discounted back to the present at the given interest rate.
The formula for the present value of an annuity is:
PV = C * ((1 - (1 + r)^-n) / r)
Where:
PV = Present Value (amount to be invested today)
C = Annual payment
r = Interest rate
n = Number of payments
In this case, the annual payment (C) is $2,500, the interest rate (r) is 8%, and the number of payments (n) is 40.
Let's calculate the present value for Ed's trust:
PV = $2,500 * ((1 - (1 + 0.08)^-40) / 0.08)
= $2,500 * ((1 - 1.08^-40) / 0.08)
Using a calculator or spreadsheet, the present value of Ed's trust comes out to be approximately $82,107.
Therefore, the grandfather must put $82,107 into Ed's trust today to ensure that he has the same retirement nest egg as Steve after the last payment is made on their 65th birthday.
