Stores i. 212.18 NPV. Since NPV is positive, the investment would increase the financial value of the investor's assets. Calculating NPV for Grouped Cash Flows. A maximum of 80 cash flow amounts (in addition to the initial investment CF0) can be stored in the hp 12c platinum.* However, problems involving more than 80 cash flows can be handled if among the cash flows there are equal consecutive cash flows. For such problems, you merely enter along with the amounts of the cash flows the number of times - up to 99 - each amount occurs consecutively. This number is designated Nj, corresponding to cash flow amount CFj, and is entered using the ga keys. Each Nj is stored in a special register inside the calculator. This method can, of course, be used for problems involving fewer than 80 cash flows - and it will require fewer storage registers than the method described above under Calculating NPV for Ungrouped Cash Flows. Equal consecutive cash flows can be entered using that method - provided there are enough storage registers available to accommodate the total number of individual cash flows. The facility of grouping equal consecutive cash flows is provided to minimize the number of storage registers required. Note: When entering cash flow amounts - including the initial investment CF0 - remember to observe the cash flow sign convention by pressing Þ after keying in the amount for a negative cash flow. * If you have stored a program in the calculator, the number of registers available for storing cash flow amounts may be less than 81.
