Cost estimates are stated in ___ value terms.

• A. Present value
• B. Future value
• C. Nominal value
• D. Real value

Answer: (A)

Understanding the time value of money is key here. Cost estimates are stated in present value terms so you compare costs that occur at different times on a common basis—today’s value. Money available now can earn interest, so future costs must be discounted back to today to reflect what they’re truly worth now. This makes decision analysis fair and consistent across alternatives. For example, a payment of 1,000 dollars one year from now discounted at 5% has a present value of about 952 dollars. That’s why present value is used: it expresses all costs in today’s dollars, accounting for the fact that later costs are worth less today. Future value would tell you what money will be worth in the future, not what it’s worth today. Nominal value ignores the time and discounting, and real value adjusts for inflation using a base year, which serves a different purpose. So the best term is present value.
