Time Value of Money (TVM)

What is the Time Value of Money? – TVM Definition

Time Value of Money (TVM) is the concept that money paid or received in the future is not valuable as is money paid or received today because the money received today can be invested and thus will increase in value.

Explanation

Perhaps you have heard the advertisements that claim that beginning at age 30, if you invest $2,000 a year in an Individual Retirement Account (IRA), you will accumulate over $500,000 by the time you retire at age 650. As the advertisements claim, you will receive substantially more than the $70,000 ($2,000 X 35 years) you invested because of the interest that you will earn on your investment. This points out the importance of interest and how quickly it accumulates over a period of time. The focus of this article is on the time value of money and how this concept is used in personal and business financial decisions.

All investment decisions revolve around giving up a certain amount of money today in the hope of receiving a greater amount at some future time. In order to determine whether you have made a wise investment, you must consider the time value of money.

Example

For example, assume that you were given the following investment opportunity:

A real estate developer offered to sell you a vacant lot today for $100,000 and guaranteed to repurchase it 10 years later for a minimum of $250,000. Does that sound like a good investment? Although it is tempting to say yes, because you would be making a profit of $150,000, you must also consider the time value of money. The $250,000 you will receive in 10 years is not really comparable to the $100,000 you have to give up today.

This is because the money that you will receive in the future will not be as valuable as the money you receive today. This is due to the fact that money received today can be invested and, as a result, will increase in amount. In our example, if you did not make the investment but instead put the $100,000 in a savings account that earned 12% interest per year, you would accumulate over $310,000 at the end of 10 years.

Concepts  related to Time Value of Money (TVM)

The best way to analyze investment opportunities such as this is to determine the rate of return they offer. In the above example, if you invested $100,000 today and received $250,000 in 10 years, you would earn a rate of return of about 9.6%. You can compare this rate of return with those of other investments of similar risk and logically decide which one presents the best opportunity. In order to make this and similar analyses, you must understand five concepts related to the time value of money.
