Analyzing Cash Flows
The various functions used to analyze cash flows are located in the NPV P and IRR R
menus. If you press
R or P before entering cash flows, you will be redirected to the
cash flow menu to enter values into the cash flow list. The menu maps for the IRR and NPV
menus are shown in Figure 2. Table 5-3 describes the items within these menus. The results
shown in Table 5-4 are based on the values entered in the cash flows as shown in Table 5-2.
