Examples
You called July leftover the margin
You run a scoop shop that also sells pints to go. July net sales, after a $48 catering credit to an events client, come to $27,640. Cost of goods sold for the mix, cones, and toppings that sold is $9,180 from your dairy bills; leftover tubs in the freezer stay on inventory. The July 31 income statement in QuickBooks Online shows Gross Profit $18,460. When you tell your partner July margin was eighteen thousand, you mean that line: the official use of this word is gross profit, and shop rent and scoopers' wages sit below it.
A broker margin loan is not leftover sales
You run a glass shop and keep leftover cash in a brokerage account. On November 6 you borrow $9,200 against those stocks, a broker margin loan, to replace a failed tempering oven, and the draw lands in business checking. Interest later posts as interest expense, and the loan is a liability, not leftover sales. Margin on the November P&L is still gross profit: net sales minus cost of glass that sold. Do not post the broker draw to sales or cost of sales.
Why it matters
On the books, margin is another name for gross profit: net sales minus cost of goods sold. You will read that leftover every close if you sell product, and you will hear the word whenever someone points at the leftover sales line. Mix it with marginal income or contribution margin and you have subtracted only the costs that move with the sale, not the full sold-goods line. A broker margin loan is borrowed cash against securities, not leftover sales, so do not treat a loan draw as the shop's product leftover.
