Definition: The monetary value of what a retailer made after cost of goods and discounts
Note: Only calculated if the product has a cost associated with it
Equation: sum(base price of unit - cost of unit - discount of unit) or sum(revenue - cost)
Example: Profit is what you are putting into the bank since it is AFTER you are taking out costs and discounts. This can be viewed as a total sum over a week or viewed as a sum for each day through a week.
Retailers can use this measure to understand how much money they are bringing in AFTER the cost of goods is taken out of it, so if there has been a large increase in their cost of goods this number will be affected, revenue will not.
Note: some POS's only record cost sometimes... we only calculate profit if the transaction line had costs attached.
