Food Cost Variance
Food cost variance is the difference between the theoretical (expected) food cost and the actual food cost incurred over a given period. A positive variance means the kitchen spent more than it should have; a negative variance indicates spending came in under target.

Understanding Food Cost Variance
Food cost variance acts as a diagnostic tool for kitchen operations. Theoretical food cost is what the kitchen should have spent based on the recipes sold and their standardized ingredient costs. Actual food cost is what was really spent, derived from inventory counts and purchase records. The gap between these two numbers reveals how much waste, theft, over-portioning, or unrecorded usage is occurring.
Variance analysis is most useful when performed weekly or biweekly rather than monthly. A month-end discovery that variance ran 4% high gives the operator no chance to intervene during the period. Weekly variance tracking, by contrast, lets managers spot a spike after a single weekend service and investigate immediately — was it a large party that went unrecorded, a spoilage event in the walk-in, or a prep cook doubling a recipe without adjusting the ticket count?
Industry benchmarks suggest that a variance under 2% of total food cost is acceptable for a well-run operation. Variance between 2% and 5% signals process gaps that need attention — typically portion control, waste logging, or receiving procedures. Variance above 5% often points to systemic problems: recipes that don't reflect actual kitchen practice, unrecorded comps and staff meals, or inventory shrinkage.
Formula
Food Cost Variance
Variance % = (Actual Food Cost - Theoretical Food Cost) / Theoretical Food Cost x 100
A positive result means over-spending; a negative result means under-spending relative to standard recipes.
Example: Weekly Variance Check
A bistro sold 620 covers last week. Based on the POS mix and standardized recipe costs, theoretical food cost was €3,100. The actual food cost — calculated from beginning inventory + purchases - ending inventory — was €3,410.
Food cost variance = €3,410 - €3,100 = €310 (10% over). Investigation revealed that 15 kg of salmon was received on Monday but not recorded in the inventory system until Thursday, and the prep team had been over-portioning the risotto by roughly 20%. Fixing receiving procedures and re-training on portion sizes brought the following week's variance down to 1.8%.
Why Food Cost Variance Matters
Without measuring variance, a restaurant has no way to distinguish between a recipe cost problem and an execution problem. A dish may be perfectly priced on paper, but if the kitchen consistently over-portions it or wastes 15% of the protein during prep, the actual margin is far lower than the menu engineering spreadsheet suggests. Variance bridges the gap between theory and reality.
Tracking variance also creates accountability. When the kitchen team knows that variance is measured every week, behavior changes — waste gets logged more carefully, portions get checked against spec, and receiving staff verify quantities against invoices. The act of measurement alone drives improvement, even before any corrective actions are taken.
Recipe Costing
Cucinovo calculates theoretical cost per portion for every recipe. Compare against actual spend to identify variance drivers and tighten kitchen operations.

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.
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.
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.
