A question specifies that there would be cost savings of 7,000 for year 1 to 6 and cash outflow at year 6 of 9000 (due to Net working capital increase). Interest rate is 12%. It asked for the NPV.
Using the calculator
N = 6
FV = -9000
PMT = +7000
I = 12
PV = -24,220.17
I cannot understand how the PV can be a negative amount? Working it out manually in excel says that it should actually be a positive 24,220.17 (cash inflow).
Could someone help me out please?
