Question

Discounted cash flow method is mainly used for

• A. Depreciation
• B. Profitability analysis
• C. Payout period
• D. Salvage value

Hint:

Whenever an economic problem mentions discounted metrics (like DCF, NPV, or IRR), it is referring to tools used for multi-year profitability analysis that incorporate the time value of money.

Answer 1

The Correct Option is B

Concept: The Discounted Cash Flow (DCF) method is an economic valuation technique used to assess the financial viability of a project. It accounts for the time value of money by discounting future cash flows back to their present value using a specified discount rate or minimum acceptable rate of return.

Step 1: Explaining the application of the DCF method.
The DCF framework calculates metrics such as Net Present Value (NPV) and Internal Rate of Return (IRR): \[ \text{NPV} = \sum_{t=0}^{n} \frac{\text{CF}_t}{(1 + r)^t} \] Where \(\text{CF}_t\) represents the cash flow at year \(t\) and \(r\) is the discount rate. By summing the discounted cash inflows and outflows over the entire project life, engineers can determine if a project will be profitable. Therefore, DCF is primarily used for comprehensive profitability analysis, matching option (2).

Step 2: Disproving alternative choices.

• Option (1): Depreciation is an accounting method used to allocate the cost of a physical asset over its useful life.

• Option (3): The standard payout period calculation measures the time to recover initial investments without discounting future cash flows.

• Option (4): Salvage value is the estimated resale value of an asset at the end of its useful life.
