Cash Flows
Figure 1 Cash Flow Diagram
In the calculator, a cash flow list is a set of numbered pairs, CF(n) and #CF(n) , where n is the index of the cash flow list. Each
pair represents one or more cash flows in a cash flow diagram. As with TVM problems, it helps to sketch a cash flow diagram
as a first step in solving cash flow problems. For some examples of cash flow diagrams, see Figure 3 at the end of this
chapter.
CF(n) represents the monetary value of the cash flow; #CF(n) represents the number of consecutive occurrences of that cash
flow. By default, #CF(n) is equal to 1 , as most cash flows occur only once. However, in cases where a cash flow is repeated
multiple times, using #CF(n) instead of entering the cash flow value multiple times saves calculation time and memory space
in the calculator.
