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.

Understanding Contribution Margin
While food cost percentage is a ratio, contribution margin is an absolute euro amount — and in many cases, it is the more useful metric. A dish with a 35% food cost and a €28 menu price contributes €18.20 per plate. A different dish with a leaner 25% food cost but a €12 menu price contributes only €9.00. The first dish is more valuable to the business even though its food cost percentage is higher, because each sale puts more euros toward fixed costs and profit.
Contribution margin is the metric that drives menu engineering. When classifying items as Stars, Plowhorses, Puzzles, or Dogs, it is the contribution margin — not food cost percentage — that determines which axis an item falls on for profitability. A restaurant that focuses solely on keeping food cost percentages low may inadvertently deprioritize its most valuable dishes in absolute-dollar terms.
Total contribution margin for a period is calculated by multiplying each dish's per-plate contribution margin by the number of units sold, then summing across the menu. This total must be enough to cover all non-food costs (labor, rent, utilities, insurance, marketing) and leave a profit. If it falls short, the restaurant is losing money regardless of how healthy individual food cost percentages appear.
Formula
Contribution Margin
Total Contribution Margin = Σ (Contribution Margin per Dish × Units Sold)
Contribution Margin Ratio = (Contribution Margin ÷ Menu Price) × 100
Example: Comparing Two Menu Items
A restaurant's lobster risotto sells for €32 with a plate cost of €11.20 (food cost: 35%, contribution margin: €20.80). Its margherita pizza sells for €13 with a plate cost of €2.60 (food cost: 20%, contribution margin: €10.40). The pizza has a much better food cost percentage, but the risotto contributes twice as much per plate to the bottom line.
If the restaurant sells 60 risottos and 150 pizzas per week, total contribution is: risotto 60 × €20.80 = €1,248, pizza 150 × €10.40 = €1,560. The pizza wins on total contribution due to volume, but the risotto is more efficient per plate — promoting it could be more profitable than promoting more pizza sales.
Why Contribution Margin Matters
Contribution margin reveals the economic truth behind food cost percentages. A restaurant that obsesses over keeping food cost below 30% may avoid premium ingredients that could generate far more profit per plate. The goal is not to minimize food cost — it is to maximize the total contribution margin across the entire menu.
Understanding contribution margin also helps with pricing decisions and promotions. Offering a 10% discount on a high-margin dish might increase volume enough to generate more total contribution, while the same discount on a low-margin dish simply destroys profit. Every pricing, portioning, and promotion decision should be evaluated through the lens of contribution margin impact.

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.
Menu Engineering
Menu engineering is the systematic analysis of a menu's items based on their profitability and popularity, used to optimize menu design, pricing, and item placement. It classifies every dish into one of four categories to guide strategic decisions.
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.
