Establish your pour cost — the cost it takes to make a drink — divided by the price that you sell it for. It should be 20–25%.
Calculate your cost per ounce by dividing the cost of the bottle by the number of ounces that it holds.
Cost per ounce x pour size. This will give you your cost per drink.
Cost per drink x 5 (to cover other variables) and round the price to the nearest quarter.
