LectureNotes said an investment’s period is the expected time to recover the initial investment amount.

Answer:
Indeed, @LectureNotes provides a concise definition of the concept commonly known as the “payback period” in the context of investments.

Solution By Steps:

  1. Understanding the Payback Period

    • The payback period is a fundamental financial metric used to evaluate the viability and risk of investments. It refers to the time required for an investment to generate an amount of revenue or cash flows equivalent to the cost initially invested.

  2. Calculating the Payback Period

    • The payback period can be calculated using the following steps:

      a. Listing Initial Investment Cost:

      • This is the total amount of money spent at the start of the investment. For example, if the initial cost is $10,000, this would be your starting point.

      b. Annual Cash Inflows:

      • Determine the expected annual cash inflows from the investment. Suppose the project generates $2,500 per year.

      c. Payback Period Formula:

      • The formula for the payback period when annual cash inflows are constant is:

        \text{Payback Period} = \frac{\text{Initial Investment}}{\text{Annual Cash Inflows}}

      Using the numbers from the example:

      \text{Payback Period} = \frac{10,000}{2,500} = 4 \text{ years}

  3. Advantages and Disadvantages

    Advantages:

    • Simplicity: Easy to calculate and understand.
    • Risk Assessment: Helps in assessing the risk by showing how quickly an investment can be recovered.

    Disadvantages:

    • Ignores Time Value of Money: Does not consider the present value of future cash flows.
    • Ignores Post-Payback Period Returns: Does not account for any returns generated after the payback period.

  4. Example Calculation with Variable Cash Flows

    • If the annual cash inflows vary, the calculation involves summing the cash flows each year until the cumulative total equals the initial investment.

      Example:

      • Initial Investment: $10,000
      • Year 1: $3,000
      • Year 2: $3,500
      • Year 3: $2,500
      • Year 4: $1,000

      Step-by-Step Calculation:

      • End of Year 1: $3,000
      • End of Year 2: $3,000 + $3,500 = $6,500
      • End of Year 3: $6,500 + $2,500 = $9,000
      • End of Year 4: $9,000 + $1,000 = $10,000

      The payback period is exactly 4 years since the cumulative cash inflow matches the initial investment at the end of year 4.

Final Answer: The payback period is the time it takes for an investment to generate cash flows equivalent to the initial investment cost, effectively recovering the original expenditure. This period is critical in determining the risk and liquidity of an investment.

By understanding and applying the concept of the payback period, investors can make more informed decisions about where to allocate their resources efficiently.
