Calculating Cash Flows
Calculating a Cash Flow
Use the cash flow functions (menu items
7
and
8
) to analyze the value of
money over equal time periods. You can enter unequal cash flows,
which can be cash inflows or outflows. The syntax descriptions for
npv(
and
irr(
use these arguments.
•
interest rate
is the rate by which to discount the cash flows (the cost of
money) over one period.
• CF0
is the initial cash flow at time 0; it must be a real number.
•
CFList
is a list of cash flow amounts after the initial cash flow
CF0
.
•
CFFreq
is a list in which each element specifies the frequency of
occurrence for a grouped (consecutive) cash flow amount, which is
the corresponding element of
CFList
. The default is 1; if you enter
values, they must be positive integers < 10,000.
For example, express this uneven cash flow in lists.
