This is a question about financial terms and definitions in English.
Gross Margin = Revenue - COGS
Gross Profit Margin = (Revenue - COGS) / COGS
In the first equation we also mean Profit
(Gross Profit Margin = Revenue - COGS
), don't we?
Why does adding a word Profit
(in Gross Profit Margin) turns a sum of money Revenue - COGS
into a ratio (Revenue - COGS) / COGS
?
