UNDERSTAND THE RESULT
Profit, ROI and margin answer different questions.
The same sale can look very different depending on whether you measure cash profit, return on invested capital or profit as a share of sale revenue.
ROI
Profit compared with the total money invested in the item and transaction.
Profit margin
Profit measured as a percentage of the final sale proceeds.
