What is Time Value of Money?

The time value of money means a dollar today is worth more than a dollar tomorrow because today’s dollar can earn interest. Provided that money can earn interest, any amount of cash is worth more the sooner it is received. TVM serves as the mathematical foundation for compound interest, discounted cash flow analysis, and retirement projections, which the SEC emphasizes as vital knowledge for individual investors.

The mathematical components of TVM include present value, future value, interest rate, compounding frequency, and time. Inflation also reinforces TVM, as rising prices erode the future purchasing power of deferred cash payouts, requiring interest compensation to offset the delay.

PRACTICAL EXAMPLE

An individual is offered a choice between receiving $10,000 today or $10,000 in three years. By accepting $10,000 today and investing it in a low-risk CD at 5.0% compounded annually, the money grows to $11,576.25 in three years, representing the time value of money.
