Well I dont know about off premise sales, but on premise runs about like this...these are the general cost of sales numbers. Liquor 13%-17%. Beer (bottles)26%-31%. Beer (draft) 18%-26%. Wine-30%-47%. So the gross margin would be the reverse. Liquor 83%-87%.
Calculating a profit. A profit is made when something is sold for more than it cost to buy. It is the money made on a deal. When money is lost on a deal, it is called a loss. To work out how much profit is made on something you have to first find out how much it cost, then how much it was sold for. The difference between these two is the profit, or loss. Have a look at the example below. Example. A greengrocer bought 8 bunches of grapes for Â£6.24 and was able to sell them all for Â£1.20 per bunch. How much profit did the greengrocer make? Selling price = 8 x Â£1.20 = Â£9.60. Profit = Â£9.60 - Â£6.24 = Â£3.36
