Why is a dollar today generally more valuable than a dollar in the future for investment decisions?

• A. A dollar today is worth more than a dollar tomorrow due to earning potential.
• B. A dollar tomorrow is worth more due to inflation.
• C. Time value of money does not affect investment decisions.
• D. The time value only affects interest rates, not discounting.

Answer: (A)

The time value of money is the idea that money available today is worth more than the same amount in the future because it can be invested to earn a return. If you have $1 today and invest it, it can grow over time; for example, at a 5% return it becomes $1.05 after one year. That earning potential makes the present dollar more valuable than a dollar tomorrow. In investment decisions, you compare how much future cash is worth in today’s terms by applying a discount rate, which reflects the opportunity to earn returns now. The statement that highlights earning potential—money today can be invested to generate more money in the future—best captures why a dollar today is generally more valuable. Inflation affects purchasing power, but it doesn’t fully explain the fundamental reason why current money is worth more. The other ideas incorrectly suggest the time value doesn’t matter or that it only relates to interest rates without discounting.
