Time Value of Money (TVM) is an important concept in financial management. It can be used to compare investment alternatives and to solve problems involving loans, mortgages, leases, savings, and annuities.

TVM is based on the concept that a dollar that you have today is worth more than the promise or expectation that you will receive a dollar in the future. Money that you hold today is worth more because you can invest it and earn interest. After all, you should receive some compensation for foregoing spending. For instance, you can invest your dollar for one year at a 6% annual interest rate and accumulate $1.06 at the end of the year.  You can say that the future value of the dollar is $1.06 given a 6% interest rate and a one-year period. It follows that the present value of the $1.06 you expect to receive in one year is only $1.

A key concept of TVM is that a single sum of money or a series of equal, evenly-spaced payments or receipts promised in the future can be converted to an equivalent value today.  Conversely, you can determine the value to which a single sum or a series of future payments will grow to at some future date.

You can calculate the fifth value if you are given any four of: Interest Rate, Number of Periods, Payments, Present Value, and Future Value.  Each of these factors is very briefly defined in the right-hand column below.  The left column has references to more detailed explanations, formulas, and examples.

Interest Rate in Calculations

• Time Value of Money calculations always use compound interest.
• You must adjust the interest rate and the number of periods to be consistent with compounding periods. For example a 6% interest rate compounded semiannually for five years should be entered 3% (6 / 2) for 10 (5 * 2) periods.
• A  calculator expects a 6% interest rate to be entered as the whole number 6 whereas formulas typically use a decimal value of .06.
