Pour cost and beverage waste: calculate the difference

The POS shows what was recorded as sold. It does not, on its own, show how much was poured from bottles and kegs. Understanding beverage cost requires sales data, recipes, deliveries and physical stock counts.

Two calculations for different purposes

For an individual drink, theoretical cost percentage is recipe ingredient cost divided by selling price. Use amounts excluding VAT. Include all ingredients, including mixers and garnishes.

For a reporting period, calculate consumption instead:

Opening stock value + purchases − closing stock value = cost of consumption.

Adjust for documented transfers between venues and supplier returns. Divide consumption by beverage sales excluding VAT for the same period. The same inventory and consumption principle is explained in BCcampus’s restaurant management textbook.

Hypothetical example: opening stock is SEK 20,000, purchases SEK 15,000 and closing stock SEK 18,000. Consumption is SEK 17,000. With beverage sales of SEK 68,000, the cost percentage is 25%. All amounts exclude VAT.

Compare with expected consumption

Multiply the number of drinks sold by the relevant recipe quantities and ingredient costs. Add them up for the same period as the stock count. This creates a theoretical figure to compare with actual consumption.

A variance does not automatically mean theft or waste. Counting errors, changed purchase prices, transfers, incorrect product entries and outdated recipes can also explain it. State whether a variance is measured in currency, a percentage of consumption or percentage points of sales; these measures are not interchangeable.

Make the routine workable during service

Use clear recipes and measuring tools. Record remade drinks, spills and discarded products consistently. Investigate foaming beer or discarded open wine bottles before drawing conclusions about staff behaviour.

Count stock consistently at comparable times. Decide how to estimate open bottles and have another person check significant differences. Consistency makes comparisons more useful than apparently precise figures produced using different methods.

Use the POS as a source of sales records

Vendion Analytics helps you review recorded sales and product mix. AI can support analysis, but POS sales are not a physical stock count and cannot locate every missing centilitre by themselves.

Start with one category, such as wine by the glass. Track purchases, recipes, sales and remaining stock over a defined period. Address the clearest cause and measure again. This gives you a better basis for decisions than targeting an unsupported industry average.
