Which financial concept states that funds will be worth less in the future?

The concept that funds will be worth less in the future is articulated through the Time Value of Money. This principle asserts that a specific amount of money today has a greater value than the same amount in the future due to its potential earning capacity. Reasons for this decreased value include inflation, which erodes purchasing power over time, and opportunity costs, where money can be invested to generate returns.

In contrast, Present Value focuses on determining the current worth of a sum that is to be received in the future, taking into account factors like interest rates. Future Value calculates how much an investment made today will grow over time at a specific interest rate. The Capital Asset Pricing Model pertains to quantifying the relationship between systematic risk and expected return in financial markets, and it does not directly address the erosion of funds' value over time. Thus, the Time Value of Money fundamentally captures the idea that funds will be worth less in the future due to these economic factors.
