Audience and Use Profile The following definition is written for students studying finance or business and adults learning to manage their personal finances and obtain the greatest return from their investments. The concepts of Interest, Future Value, Present Value, Annuity, Investment and Compounding are vital to understanding and calculating Time Value of Money. They must have some knowledge and experience with handling expenses and saving money, preferably owning a personal savings or checking account themselves or looking into it.

TIME VALUE OF MONEY

Introduction Time Value of Money is the core principle of finance that money available at the present time is worth more than the same amount in the future, due to its potential earning capacity. This idea holds that—provided money can earn interest—any amount of money is worth more the sooner it is received. The time value of money serves as the foundation for all other notions in finance. It impacts business finances, consumer finances and government finances. Time value of money results from the concept of interest. It can be used to compare investment alternatives and to solve problems involving loans, mortgages, leases, savings, and annuities.

Example Time value of money can be illustrated by the fact that a dollar received today is worth more than a dollar received a year from now because today's dollar can be invested and earn interest as the year elapses. For example, assuming a 5% interest rate, $100 invested today will be worth $105 in one year ($100 multiplied by 1.05). Conversely, $100 received one year from now is only worth $95.24 today ($100 divided by 1.05), assuming a 5% interest rate. These calculations demonstrate that time literally is money. The value of money now is not the same as it will be in the future, and vice versa. So, it is important to know how to calculate the time value of money in order to distinguish between the worth of investments that offer returns at different times.

Operating Principle The time value of money is based on the premise that people prefer to receive a certain amount of money today, rather than the same amount in the future, all else equal. As a result, you demand interest, paid either along the way or at the end. The interest compensates you for the time in which the money could be put to productive use, the risk of default, and the risk of inflation. Implicit in any consideration of time value of money are the rate of interest and the period of compounding. Time Value of Money is determined by the mathematics of Compound Interest— the difference between the value of a sum of money at one point in time and its value at another point in time. Three formulas are used to calculate the time value of money: NOTE: r = the required rate of return per time period n = the number of time periods. 1. The present value formula is used to discount future money streams: that is, to convert future amounts to their equivalent present day amounts. The following factors can convert between present value and future value:  ( Future Value / Present Value ) = ( 1+r )n  ( Present Value / Future Value ) = 1 / ( 1+r )n 2. The future value formula is used to compound today's money into the equivalent amount at some time in the future (i.e., to compound money in either a lump sum or streams of payments). The following factors can be used to convert between future value and annuity amount:  ( Future Value / Annuity ) = [( 1+r )n – 1] / r  ( Annuity / Future Value ) = r / [( 1+r )n - 1] 3. The present value of an annuity formula is used to discount a series of periodic payments of equal amounts to the present day. Variations of this formula can find the future value of the annuity, or solve for the annuity given the present value (for example, finding monthly mortgage payments) or find the annuity given the future value (for example finding a monthly payment needed to reach a retirement savings goal). The following factors can convert between present value and annuity:  ( Present Value / Annuity ) = ( 1+r )n - 1 / ( 1+r )n  ( Annuity / Present Value ) = r ( 1+r )n / ( 1+r )n - 1 NOTE: Time Value of Money Tables, Financial Calculators, Spreadsheet Software, and Time Value of Money Software can also be used to calculate the Time Value of Money.

Special Conditions Time Value of Money also takes into account risk aversion—both default and inflation risk. 100 monetary units today is a sure thing and can be enjoyed now. In five years, however, that money could be worthless or not returned to the investor. There is a residual time value of money,

beyond compensation for default and inflation risk, which represents simply the preference for consumption now versus later. Inflation-indexed bonds notably carry no inflation risk. In the United States for instance, Treasury Inflation-Protected Securities carry neither inflation nor default risk, but pay interest. References Kapoor, Dlabay, and Hughes. Personal Finance 8e.
