Menu Engineering Calculator. Enter up to 6 menu items with their selling price, food cost, and quantity sold to classify each item as a Star, Plow Horse, Puzzle, or Dog. Your results include each item's contribution margin, menu mix %, and a profitability grade — giving you a clear picture of which dishes to promote, reprice, or remove. Also try the Cost per Edible Portion — Edible Portion Cost.
Menu engineering is the strategic analysis of a restaurant's menu items based on their profitability (contribution margin) and popularity (sales volume). By classifying items into four categories — Stars, Plow Horses, Puzzles, and Dogs — operators can make data-driven decisions about pricing, placement, and promotion to maximize overall profit.

Contribution margin is simply the selling price minus the food cost: CM = Selling Price − Food Cost. For example, a dish priced at $18 with a food cost of $6 has a contribution margin of $12. This represents how much each sale contributes to covering labor, overhead, and profit.
Stars are high-margin, high-popularity items — your best performers. Plow Horses are popular but low-margin; they sell well but need cost reduction or repricing. Puzzles are high-margin but low-popularity; they need better marketing or placement. Dogs are low-margin and low-popularity — candidates for removal or a complete overhaul.
Most full-service restaurants target a food cost percentage between 28% and 35%. Quick-service or fast-casual concepts may aim for 25–30%. Items above 40% food cost are generally considered high-cost and should be repriced or reformulated unless they serve a strategic purpose on the menu.
Not necessarily. Some Dog items may serve as anchor items, loss leaders, or dietary accommodations that improve overall guest satisfaction. Before removing a Dog, consider whether you can reduce its food cost, reposition it on the menu, or bundle it with higher-margin items. Only eliminate it if it adds no strategic value.
Puzzle items have strong margins but weak sales — the fix is usually about visibility and perception. Try featuring them with better menu placement (top-right is prime real estate), adding appealing descriptions, training staff to recommend them, or running limited-time promotions. If the price is too high, a modest reduction may boost volume enough to tip them into Star territory.
Most restaurant consultants recommend a full menu engineering review every 3 to 6 months, or whenever you change your menu significantly. You should also run analysis after any major cost changes (ingredient price spikes, new suppliers) or seasonal menu updates to ensure your pricing and mix still reflect current realities.
Menu mix percentage (also called popularity index) is each item's quantity sold divided by the total quantity sold across all items, expressed as a percentage. An item is considered 'high popularity' if its menu mix exceeds the theoretical equal share (100% ÷ number of items × 70% threshold). This calculator uses the median sales volume as the popularity threshold. You might also find our Inventory Turnover Calculator (Food) useful.
