Question 2

Marvin hopes to accumulate $1,000,000 in his retirement plan by making equal contributions at the end of each month for 35 years. He is planning to earn 10.8% compounded monthly. What amount should he deposit every month?

Accepted Answer

To find the monthly deposit amount for Marvin's retirement plan, we use the formula for the future value of an annuity, which is $FV = P \times \frac{(1 + r)^n - 1}{r}$, where $FV$ is the future value, $P$ is the monthly payment, $r$ is the monthly interest rate, and $n$ is the total number of payments. Here, $FV = \$1,000,000$, annual interest rate $= 10.8\%$, so the monthly interest rate $r = \frac{10.8\%}{12} = 0.9\%$, and $n = 35 \times 12$ months. Rearranging the formula to solve for $P$, and substituting the given values, we find that the correct monthly deposit amount is closest to option B, $213.87.

Question 4

Vince has $35,000 to purchase an annuity that will provide him with equal payments at the end of every three months for the next six years. If the funds earn 8% compounded quarterly, what is the size of the quarterly payments he will receive?

Accepted Answer

The size of the quarterly payments can be calculated using the formula for the present value of an annuity: $PV = PMT \times \left[\frac{1 - (1 + r)^{-n}}{r}\right]$, where $PV$ is the present value of the annuity (initial investment), $PMT$ is the payment per period, $r$ is the interest rate per period, and $n$ is the total number of payments. Given that Vince has $35,000 to invest at an 8% annual interest rate compounded quarterly, the quarterly interest rate is $8\% / 4 = 2\%$, or $0.02$ as a decimal. The total number of quarterly payments over six years is $6 \times 4 = 24$. Rearranging the formula to solve for $PMT$ gives us $PMT = PV \times \frac{r}{1 - (1 + r)^{-n}}$. Substituting the given values, we get $PMT = 35000 \times \frac{0.02}{1 - (1 + 0.02)^{-24}}$, which calculates to approximately $1,850. Thus, the size of the quarterly payments Vince will receive is about $1,850.

Question 9

Calculate the size of the monthly mortgage loan payment if a $121,500 loan at 7% compounded semi-annually is to be paid off over 18 years.

Accepted Answer

The correct calculation involves using the formula for a fixed-rate mortgage, which is often represented as $M = P\frac{r(1+r)^n}{(1+r)^n-1}$, where $M$ is the monthly payment, $P$ is the principal loan amount, $r$ is the monthly interest rate (annual rate divided by 12), and $n$ is the total number of payments (years times 12). Given a 7% annual interest rate compounded semi-annually, we first adjust this to a monthly rate by dividing by 12, but since it's compounded semi-annually, we use the effective annual rate formula to adjust the interest rate. However, for simplicity in common mortgage calculations, we directly use the nominal rate divided by 12 for monthly calculations. For an 18-year term, or 216 months, the calculation is plugged into the formula. The closest match to the correct calculation based on the options provided is $983.75.

Question 10

What annual deposit should Martina make to her RRSP at the end of every year if the funds earn 12% compounded monthly and her goal is to accumulate $1,000,000 at the end of 25 years?

Accepted Answer

We can use the formula for future value of an annuity to solve this problem:

FV = PMT * (((1 + r/n)^(n*t)) - 1) / (r/n)

where FV is the future value, PMT is the annual deposit, r is the annual interest rate, n is the number of times interest is compounded per year, and t is the number of years.

Plugging in the numbers given:

$1,000,000 = PMT * (((1 + 0.12/12)^(12*25)) - 1) / (0.12/12)

Simplifying:

$1,000,000 = PMT * 214.855

PMT = $4,654.60 (rounded to the nearest cent)

Therefore, the closest answer choice is B) $6,750. None of the other answer choices are close to $4,654.60 or each other, so they can be eliminated.

Question 11

An investment of $25,000 is made for a 10-year term. After the term expires, equal withdrawals will be made at the end of every month for 15 years. What will the size of the monthly withdrawal be if the investment earns 9% compounded monthly for both the deposit and withdrawal periods.

Accepted Answer

To solve the problem, we need to find the accumulated value of the investment after 10 years and then calculate the equal monthly withdrawals for 15 years. We can use the formula for the future value of an annuity:

FV = PMT[((1+r)^n-1)/r]

where FV is the future value, PMT is the monthly payment, r is the monthly interest rate, and n is the number of months.

For the first 10 years, the investment earns 9% compounded monthly, so the future value is:

FV1 = 25000(1+0.09/12)^(10*12) = 69387.63

For the next 15 years, we need to find the monthly payment that would exhaust the accumulated value in 180 months:

69387.63 = PMT[((1+0.09/12)^180-1)/(0.09/12)]

PMT = 621.58

Therefore, the monthly withdrawal will be $621.58.

Question 12

How much will Clarence have to invest at the end of every year at 11% compounded annually if he is going to accumulate $25,000 in five years?

Accepted Answer

We can use the formula for the Future Value of an Annuity:
FV = PMT x ((1 + r)^n - 1) / r
where FV is the future value, PMT is the periodic payment, r is the interest rate per period, and n is the number of periods.

In this problem, we know that FV = $25,000, r = 11%, and n = 5 years. We want to find the PMT.

Plugging in the values, we get:
$25,000 = PMT x ((1+0.11)^5 - 1) / 0.11

Solving for PMT:
PMT = $4,014.25

Therefore, Clarence will have to invest $4,014.25 at the end of every year for five years to accumulate $25,000. The best choice is (C).

Question 17

If you have $45,000 earning 9.6% compounded monthly, how much money could you take out of the investment at the end of every year for 10 years?

Accepted Answer

To solve this problem, we can use the formula for the future value of an annuity:

FV = PMT x [(1 + r/n)^(nt) - 1] / (r/n),

where FV is the future value of the annuity, PMT is the amount of each payment, r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the number of years.

We can rearrange this formula to solve for PMT:

PMT = FV x (r/n) / [(1 + r/n)^(nt) - 1].

In this problem, we want to find the maximum amount that can be withdrawn from the investment each year for 10 years. We can assume that the initial investment of $45,000 remains untouched and earns interest for the entire 10-year period.

Using the given information, we can calculate the future value of the investment after 10 years:

FV = $45,000 x (1 + 0.096/12)^(12x10) = $123,333.58

We can also find the maximum amount that can be withdrawn each year by plugging in the values for PMT, FV, r, n, and t:

PMT = $123,333.58 x (0.096/12) / [(1 + 0.096/12)^(12x10) - 1] = $7,334.05

So the best choice is B, which is the closest option to this calculation.
