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
C to 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.
