Cash Flows 44
Editing Cash Flows
In the cash flow list, you can view and modify the current monetary value of a specific cash
flow, or cash flows. Press
<
or
>
repeatedly to scroll through the list. To modify the
displayed entry, type a new number and press
I
. For example, to change the current
monetary value of the cash flow three, CF(3), in the example in Table 5-2 from 0 to 200, with
CF(3)= displayed, press
200
followed by
I
.
You can also modify the number of occurrences of a cash flow in the same manner with #CF(n)
displayed. Pressing
:j
with a cash flow displayed erases the displayed cash flow.
Pressing
:o
inserts a cash flow into the list before the displayed cash flow.
Note that the values for the number of cash flows occurring for a given year, (#CF/Yr)
Investment interest rate, (Inv. I%), and safe interest rate (Safe I%) can be entered in both the
NPV and IRR menus*. Key in the desired number or rate followed by
I
with the item
displayed. The other items are then calculated internally.
Modified Internal Rate of Return (MIRR) and Financial Management Rate of Return
(FMRR)*
For the cash flow example you entered in Table 5-2, edit the cash flows using the cash flow
amounts and number of occurrences shown in Table 5-5 below. For the initial cash flow, CF(0),
enter -1,250,000. In the IRR menu, enter 8% for investment interest rate, and 5% as a safe rate.
Verify the number of cash flows per year, #CF/Yr, is set to 1. The results for MIRR and FMRR
are shown in Table 5-6. This example was calculated in Algebraic mode.
