  2. 2. 2 After studying this part,After studying this part, you should be able to:you should be able to: 1. Understand what is meant by "the time value of money." 2. Understand the relationship between present and future value. 3. Describe how the interest rate can be used to adjust the value of cash flows – both forward and backward – to a single point in time. 4. Calculate both the future and present value of: (a) an amount invested today; (b) a stream of equal cash flows (an annuity); and (c) a stream of mixed cash flows. 5. Distinguish between an “ordinary annuity” and an “annuity due.” 6. Use interest factor tables and understand how they provide a shortcut to calculating present and future values. 7. Use interest factor tables to find an unknown interest rate or growth rate when the number of time periods and future and present values are known. 8. Build an “amortization schedule” for an installment-style loan.

  5. 5. 5 TIMETIME allows you the opportunity to postpone consumption and earn INTERESTINTEREST. Why TIME?Why TIME? Why is TIMETIME such an important element in your decision?
  6. 6. 6 Types of InterestTypes of Interest Compound InterestCompound Interest Interest paid (earned) on any previous interest earned, as well as on the principal borrowed (lent). Simple InterestSimple Interest Interest paid (earned) on only the original amount, or principal, borrowed (lent).
  7. 7. 7 Simple Interest FormulaSimple Interest Formula FormulaFormula SI = P0(i)(n) SI: Simple Interest P0: Deposit today (t=0) i: Interest Rate per Period n: Number of Time Periods

  12. 12. 12 FVFV = P0 + SI = $1,000 + $140 = $1,140$1,140 Future ValueFuture Value is the value at some future time of a present amount of money, or a series of payments, evaluated at a given interest rate. Simple Interest (FV)Simple Interest (FV) What is the Future ValueFuture Value (FVFV) of the deposit?
  13. 13. 13 The Present Value is simply the $1,000 you originally deposited. That is the value today! Present ValuePresent Value is the current value of a future amount of money, or a series of payments, evaluated at a given interest rate.

Note that a “group” may only contain a single cash flow (e.g., $351.76). For Fnn:* This is the cash flow FREQUENCY of the nth group of cash flows. Note that this is always a positive whole number (e.g., 1, 2, 20, etc.).
