Note: Use the TVM solver for equal and regular cash flow analysis (see page 22). Entering cash flow data To find NPV and IRR using discounted cash flow analysis, enter cash flow data, one data item at a time, in the following format: Single cash flows Cash flow value J Repeated cash flows Cash flow value > frequency value J Notes: · Before entering data, press > . It is not possible to enter cash flow data when listed financial variables are shown on the display. · You can enter a total of up to 100 cash flow and/or statistical data items. A single cash flow value is counted as one data item, while a cash flow value with an associated frequency value is counted as two. · If you wish to correct a value before pressing J, press s to delete the entry and enter the correct value. Entering cash flow data Enter cash flow data according to the following cash flow diagram. $7, 000 $9, 000 $5, 000 $5, 000 $8, 000 ­$25, 000 37 Procedure Key operation Display Bring up the initial dis- s *1 play in NORMAL mode. , 25000 J 000 DATA SET:CF DATA SET:CF DATA SET:CF DATA SET:CF DATA SET:CF 000 * 100 200 300 400 2 7000 J 9000 J 5000 > 2 J 8000 J *1 *2 If there is cash flow data stored, press > .

Editing data · Display the data item you wish to modify by using z/ i, enter a new value and press J. · If a frequency value is set to zero, then the associated data set is deleted. Deleting data · Display the data item to be deleted by using z/i, and press . · If a cash flow value/frequency is deleted, the corresponding frequency/cash flow value is also deleted. Inserting data Using the z and i keys, specify the correct place to insert your new data by displaying the value that is to come directly after, and then press . A new data set with a cash flow value of zero and a frequency value of one will be inserted. Correcting cash flow data Currently the cash flow data is that shown in chart A.
