Hi Denis,
ReplyDeleteHow 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
Thanks Misa! Are my calculations correct?
ReplyDeleteYeah pretty busy indeed. I am working full time in CBD :)
*and yeah, now you know... I never read the lecture notes...
I think your calculations are correct. They are same as mine.
ReplyDeleteYou're such a hard worker:D Take care of yourself!
