											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) is 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.

To enter a cash flow list, press Cto open the cash flow menu.

For each cash flow item, first enter the monetary value followed by I, then enter the number of occurrences followed by I.

If a cash flow occurs once, you do not need to type 1I. Simply press I or <as 1 is the default.
