FINA 250 Module 3: Time Value of Money

Return to Modules


  • Understand the reinvestment of interest paid on an investment’s principal
  • Understand and calculate Future value (FV) = Present Value (PV) x Amount it has increased by the end of 1 year (1+i)
  • Define future value—the value of an investment at some point in the future
  • Define present value—the current value in today’s dollars of a future sum of money
  • Understand the importance of annual compounding —reinvesting interest at end of each year for more than 1 year
  • n is equal to the number of years during which compounding occurs

A Dollar today is always worth more than a dollar tomorrow. Why is that?

Introduction Time Value of Money:

Compound interest and the time value of money are two important factors to consider when developing a financial plan. This section explains the concept of the time value of money under three assumptions:

  1. a single payment, lump sum;
  2. a terminating fixed stream of payments, annuity; and
  3. a never-ending fixed stream of payments, perpetuity.

Calculations and applications for present value and future value are illustrated using a financial calculator. Using compound interest to generate returns is dependent on three factors:

  • length of the investment period
  • amount invested, and
  • the rate of return, or interest rate.

Finally, amortized loans and perpetuities are discussed and calculated.

Dr. Waller Lecture: Time Value of Money (video) (38:08)

A reference for your calculator work should you run into trouble. A bit long to print, but refer to the relevant sections and practice with your calculator.


  • The cornerstone of time value of money is compound interest
  • Using future-value interest factors from tables, you can determine how much investments will grow over time
  • A rise in either the interest rate or the number of years that your money is compounded for increases future values
  • An annuity is a equal dollar periodic payment of investment earnings or paying off installment loans
