Cost of Goods Sold (COGS)
Cost of Goods Sold (COGS) is the total cost of all food and beverage ingredients consumed during a specific period. It represents the direct material cost of producing the dishes a restaurant sells.

Understanding Cost of Goods Sold (COGS)
COGS is the single largest expense category for most restaurants, typically consuming 28–35% of total revenue. Unlike fixed costs such as rent or insurance, COGS fluctuates directly with sales volume and ingredient prices. A restaurant that sells more covers uses more ingredients, so COGS rises in absolute terms — but the percentage should remain stable if pricing and waste controls are effective.
The standard calculation uses a beginning-and-ending inventory approach. At the start of the period, you count everything on the shelves (beginning inventory). You add all purchases received during the period. At the end, you count inventory again. The difference is what was consumed — your COGS. This method captures not just planned recipe usage but also waste, theft, and spoilage.
COGS can be calculated for any time period — daily, weekly, or monthly — though weekly is most common in restaurant operations. Comparing COGS week over week reveals trends: a rising COGS percentage with stable menu prices signals waste, portion creep, or supplier price increases that need attention.
Formula
Cost of Goods Sold
COGS Percentage = (COGS ÷ Total Food Revenue) × 100
Some operators separate food COGS from beverage COGS for more granular analysis.
Example: Weekly Kitchen COGS
A restaurant begins the week with €4,200 in food inventory. During the week, it receives €3,800 in deliveries. At week's end, inventory count totals €3,500. COGS = €4,200 + €3,800 − €3,500 = €4,500.
If the week's food revenue was €14,000, the COGS percentage is (€4,500 ÷ €14,000) × 100 = 32.1% — within the typical target range but worth monitoring if it trends upward.
Why Cost of Goods Sold (COGS) Matters
COGS is the foundation of restaurant financial management. Without accurate COGS data, an operator cannot determine whether menu prices are adequate, whether waste is under control, or whether purchasing decisions are sound. A 2% increase in COGS percentage on €500,000 annual revenue translates to €10,000 in lost profit.
Tracking COGS also enables variance analysis — comparing actual ingredient consumption against theoretical consumption (what recipes say you should have used). A large variance indicates waste, over-portioning, theft, or inaccurate inventory counts, all of which can be investigated and corrected.
Recipe Cost Tracking
Cucinovo calculates the theoretical food cost for every recipe and tracks ingredient prices over time, giving you the data to compare actual COGS against expected consumption.

Food Cost Percentage
Food cost percentage is the ratio of a dish's total ingredient cost to its menu selling price, expressed as a percentage. It is the primary metric restaurants use to measure recipe profitability and set menu prices.
Plate Cost
Plate cost is the total cost of all ingredients required to produce one finished, plated portion of a dish. It includes every component — protein, starch, vegetables, sauces, garnishes, and condiments — that appears on the plate when it reaches the guest.
Stock Take (Inventory Count)
A stock take is the systematic physical counting and valuation of all food, beverage, and supply inventory held by a restaurant at a specific point in time. It is the foundation for calculating actual food cost and identifying variances between theoretical and real consumption.
Contribution Margin
Contribution margin is the amount of money remaining from a dish's selling price after subtracting its food cost. It represents the per-plate contribution toward covering labor, overhead, and profit.
