Time Value of Money

« Back to Glossary Index

The Time Value of Money (TVM) is a financial concept that asserts that a sum of money has a different value today compared to its value in the future due to its potential earning capacity. Essentially, it reflects the principle that money available now is worth more than the same amount in the future because of its earning potential over time. This principle is fundamental in finance and investment decision-making.

Key Components of Time Value of Money

1. Present Value (PV)

Present value refers to the current worth of a sum of money that will be received or paid in the future, discounted back to the present using a specific interest rate.

2. Future Value (FV)

Future value represents the amount of money that an investment made today will grow to over a specified period at a given interest rate.

3. Discount Rate

The discount rate is the interest rate used to determine the present value of future cash flows. It accounts for the risk and opportunity cost of investing money.

Calculating the Time Value of Money

To illustrate the TVM concept, let’s use the formula for calculating Future Value (FV):

Future Value Formula:
FV = PV × (1 + r)^n

Where:
FV = Future Value
PV = Present Value (the initial amount of money)
r = Interest rate (as a decimal)
n = Number of periods (years)

Example of Time Value of Money

Suppose you invest $1,000 today in a savings account that offers an annual interest rate of 5% for 3 years. To calculate the future value of your investment after 3 years, you would apply the formula described above.

  • PV = $1,000 (the initial investment)
  • r = 0.05 (5% interest rate)
  • n = 3 (the investment period in years)

Now, plug the values into the formula:

FV = 1000 × (1 + 0.05)^3

Calculating the values:

1. Calculate (1 + 0.05) = 1.05
2. Raise it to the power of 3: 1.05^3 = 1.157625
3. Multiply by the present value: FV = 1000 × 1.157625 = $1,157.63

So, the future value of the investment after 3 years would be approximately $1,157.63.

Understanding the time value of money is crucial for making informed financial decisions, such as investing, borrowing, or planning for retirement. It emphasizes the importance of earning interest over time, and how delaying access to funds can decrease their value.
