Interest and Annuities Questions

Multiple choice

What is the formula for calculating the Present Value (PV) of a future cash flow?

  1. PV = FV / (1 + r)^n

  2. PV = FV * (1 + r)^n

  3. PV = FV / (1 - r)^n

  4. PV = FV * (1 - r)^n
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Present Value (PV) of a future cash flow is calculated using the formula PV = FV / (1 + r)^n, where FV is the future value, r is the interest rate, and n is the number of periods.

Multiple choice

What is the formula for calculating the Internal Rate of Return (IRR) of a project?

  1. IRR = Discount rate that makes the Net Present Value (NPV) of the project equal to zero

  2. IRR = Discount rate that makes the Future Value (FV) of the project equal to zero

  3. IRR = Discount rate that makes the Present Value (PV) of the project equal to zero

  4. IRR = Discount rate that makes the Net Future Value (NFV) of the project equal to zero
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Internal Rate of Return (IRR) of a project is the discount rate that makes the Net Present Value (NPV) of the project equal to zero. It represents the annualized rate of return that the project is expected to generate over its lifetime.

What is the formula for calculating the present value of a future cash flow?

  1. PV = FV / (1 + r)^n

  2. PV = FV * (1 + r)^n

  3. PV = FV / (1 - r)^n

  4. PV = FV * (1 - r)^n
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The present value (PV) of a future cash flow (FV) is calculated using the formula PV = FV / (1 + r)^n, where r is the interest rate and n is the number of periods.

Multiple choice

What is the formula for calculating the duration of a bond?

  1. Duration = (PV of cash flows / Price of bond) / (1 + r)

  2. Duration = (PV of cash flows / Price of bond) * (1 + r)

  3. Duration = (Price of bond / PV of cash flows) / (1 + r)

  4. Duration = (Price of bond / PV of cash flows) * (1 + r)
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The duration of a bond is calculated using the formula Duration = (PV of cash flows / Price of bond) / (1 + r), where r is the interest rate.

Multiple choice

A company has a loan of \$100,000 with an annual interest rate of 5%. If the company makes monthly payments of \$1,000, how long will it take to pay off the loan?

  1. 10 years

  2. 15 years

  3. 12 years

  4. 8 years
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The monthly interest rate is 5% / 12 = 0.42%. The monthly payment is \$1,000. The loan amount is \$100,000. Using the formula for the number of months to pay off a loan: Number of months = (Loan amount * Monthly interest rate) / Monthly payment, we get Number of months = (\$100,000 * 0.0042) / \$1,000 = 144 months. Therefore, it will take 144 / 12 = 12 years to pay off the loan.

Multiple choice

A company has a portfolio of bonds with a duration of 5 years. If the interest rate increases by 1%, what is the expected change in the value of the company's portfolio?

  1. 5%

  2. 10%

  3. 15%

  4. 20%
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The expected change in the value of a bond portfolio when the interest rate changes is equal to the duration of the portfolio multiplied by the change in the interest rate. In this case, the duration of the portfolio is 5 years and the interest rate increases by 1%. Therefore, the expected change in the value of the company's portfolio is 5 years * 1% = 5%. Therefore, the expected change in the value of the company's portfolio is 5%.
