I know precisely what i am talking about....here's a kindergarten level example for you....
as a simple example....
let's say it cost me $5 bucks to make a loaf of bread, i sell that loaf of bread for $10 bucks at retail....
$10 in revenues
- $ 5 in my cost to make it
- $3 in taxes owed
___________________
= $2 dollars left in PROFIT
which is a :
20% PROFIT margin
HOWEVER, the baker really only invested $5 bucks of his own money to make the bread....
so you take the $2 bucks he made in profit at retail and divide it by what he invested, the $5 bucks.... to show what return he made on his investment... in this case he made a 40% return on his investment.
this is as simply as i can put it.....
care
Well... you put it too simply... because ROI is also speculation into the future, combining past statistics...
You have many problems with using ROI in this manner, just as you have many problems using ROI for any sort of performance measurement...
Net Income + Interest (decimal value of tax rate subtracted from 1) / Book value of Assets is not accurate in terms of true profit margin... HENCE WHY IT IS NOT CALLED PROFIT MARGIN.... ROI looks at a perceived benefit from monies invested.... as stated... you have to look at the big picture.... not just looking for the stock sticker stat that seems to fit your preconceived agenda
but nice try again
