NPV/Payback table as follows (Click to Enlarge) :



We can deduce that the payback period is 4 years.

I am not too sure what is the difference between ROI Total and ROI Annual. Anybody knows?
I know for a fact that ROI is just a percentage...

  1. Hi Denis,
    How have you been? busy with your work?
    I found the below formula in Amit's note.
    I hope this is what you want to know.

    *Lifetime ROI =
    (Cumulative Benefits –Cumulative costs)/Cumulative Costs.
    *E.g. ($795,440 -$488,692)/$488,692 = 0.628 or 62.8%

    *Yearly ROI = Lifetime ROI/number of years
