Understand the concept of present value (PV): Present value is the current worth of a future cash flow, discounted at a specific interest rate over a certain number of periods. It helps determine how much a future amount is worth today.
Identify the correct formula for computing PV: The formula for PV of a single future cash flow (FV) is derived from the principle of discounting, which accounts for the time value of money. The correct formula is PV = FV / (1 + r)^n.
Break down the formula: In the formula PV = FV / (1 + r)^n, 'FV' represents the future value of the cash flow, 'r' is the annual interest rate (expressed as a decimal), and 'n' is the number of periods until the cash flow is received.
Compare the given options: Analyze each option provided in the problem. The correct formula is PV = FV / (1 + r)^n, as it properly accounts for the compounding effect of the interest rate over 'n' periods. The other options either incorrectly multiply or divide by factors that do not represent the time value of money.
Conclude the reasoning: The correct formula, PV = FV / (1 + r)^n, ensures that the future cash flow is appropriately discounted to reflect its present value. This formula is widely used in financial accounting and investment analysis.
