What is the time value of money?

Definition of Time Value of Money

The time value of money recognizes that receiving cash today is more valuable than receiving cash in the future. The reason is that the cash received today can be invested immediately and begin growing in value. For instance, if a company receives $1,000 today and is able to invest the amount immediately at a rate of 10% per year, the company will have $1,100 after 365 days.

If the time value of money is 10%, it also means that receiving $1,100 in one year is comparable to receiving $1,000 today. Accountants will state that the future value of $1,100 has a present value of $1,000. The difference of $100 will be reported as interest income during the 365 days that the company is earning the interest.

Example of the Time Value of Money

Assume that a company provides consulting services today and agrees to receive $11,000 one year later. The $11,000 represents:

  • An amount for today's services
  • Interest compensation for the company waiting 365 days to be paid

Under the accrual basis of accounting and with a time value of money of 10%, the service revenues that were earned today amount to $10,000. The difference of $1,000 is interest income to be reported during the 365 days that the company waits for the $11,000.

Importance of the Time Value of Money in Accounting

The time value of money is important in accounting because of the accountant's cost principle and revenue recognition principle. However, the concepts of materiality and cost/benefit allow the accountants to ignore the time value of money for the routine accounts receivable and accounts payable having credit terms of 30 or 60 days.
