Zeitwertverfall

Zeitwertverfall, also known as time value of money, is a fundamental concept in finance and economics that describes the decrease in the value of money over time due to its potential earning capacity. This concept is based on the principle that a sum of money today is worth more than the same sum in the future because it can be invested and earn interest or other returns. The time value of money is crucial in various financial calculations, including present value, future value, and net present value (NPV).

The time value of money is often illustrated through the concept of compound interest, where the interest earned on an investment is reinvested, leading to exponential growth over time. Conversely, the time value of money also applies to the cost of money, where the cost of borrowing money today is less than the cost of borrowing the same amount in the future due to the opportunity cost of not investing the money elsewhere.

In practical applications, the time value of money is used in decision-making processes, such as determining the feasibility of investments, evaluating project proposals, and setting interest rates. It is also a key consideration in personal finance, where individuals seek to maximize the value of their money by investing in assets that generate returns.

The time value of money is influenced by several factors, including the interest rate, the time period, and the inflation rate. A higher interest rate or a longer time period will result in a greater decrease in the value of money. Inflation can also erode the purchasing power of money over time, further emphasizing the importance of considering the time value of money in financial decisions.
