3. 3. 3Obviously, \$10,000 today\$10,000 today.You already recognize that there isTIME VALUE TO MONEYTIME VALUE TO MONEY!!The Interest RateThe Interest RateWhich would you prefer -- \$10,000\$10,000todaytoday or \$10,000 in 5 years\$10,000 in 5 years?
4. 4. 4TIMETIME allows you the opportunity topostpone consumption and earnINTERESTINTEREST.Why TIME?Why TIME?Why is TIMETIME such an importantelement in your decision?
5. 5. 5Types of InterestTypes of InterestCompound InterestCompound InterestInterest paid (earned) on any previousinterest earned, as well as on theprincipal borrowed (lent).Simple InterestSimple InterestInterest paid (earned) on only the originalamount, or principal borrowed (lent).

8. 8. 8FVFV = P0 + SI= \$1,000 + \$140= \$1,140\$1,140Future ValueFuture Value is the value at some futuretime of a present amount of money, or aseries of payments, evaluated at a giveninterest rate.Simple Interest (FV)Simple Interest (FV)What is the Future ValueFuture Value (FVFV) of thedeposit?
9. 9. 9The Present Value is simply the\$1,000 you originally deposited.That is the value today!Present ValuePresent Value is the current value of afuture amount of money, or a series ofpayments, evaluated at a given interestrate.Simple Interest (PV)Simple Interest (PV)What is the Present ValuePresent Value (PVPV) of theprevious problem?

66. 66. 66Defining the calculator variables:For CF0: This is ALWAYS the cash flow occurringat time t=0 (usually 0 for these problems)For Cnn:* This is the cash flow SIZE of the nthgroup of cash flows. Note that a “group” may onlycontain a single cash flow (e.g., \$351.76).For Fnn:* This is the cash flow FREQUENCY of thenth group of cash flows. Note that this is always apositive whole number (e.g., 1, 2, 20, etc.).Solving the Mixed FlowsSolving the Mixed FlowsProblem using CF RegistryProblem using CF Registry* nn represents the nth cash flow or frequency. Thus, thefirst cash flow is C01, while the tenth cash flow is C10.
