|Anyone know what I have to input in order to calculate the discounted payback period with a HP12C?
Thanks for your help.
|I hope I'm not late, anyway it' worth for someone else. You can calculate NPV, if it's positive delete the last CF and calculate again, and so on until you get a negative NPV, then you know that between those years you reach the DPP. when you come up with a negative NPV you have to add that NPV with the last positive you got, that will give you the discounted CF of the last positive CF that turns a negative NPV into a positive NPV. Finally you have to divide the last negative NPV by this CF and you'll get the proportion of the year you need to reach the DPP.|
