How do you work out cash margin of beer?

To calculate the cash margin of beer, first determine the selling price per unit (e.g., a pint or bottle) and subtract the total cost of goods sold (COGS) per unit, which includes production, distribution, and any associated overhead costs. The formula is: Cash Margin = Selling Price - COGS. To find the cash margin percentage, divide the cash margin by the selling price and multiply by 100. This will give you a clear indication of the profitability of each unit sold.
