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)
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.
