Cash Flows

4 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

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

, 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

is the default.
