â–¶How do I calculate the food cost of a dish?
List every ingredient and its weight or volume. Get the price of each ingredient from your supplier (cost per pound or per liter). Divide the total ingredient cost by the as-served portion to get the per-plate ingredient cost (food cost). For example: a ribeye steak (12 oz raw, $6 per pound) costs $4.50 raw; trim and cooking loss is 25 percent, so the cooked weight is 9 oz, and the plated cost is $6.75. Add the cost of any garnish (microgreens, sea salt) to get the total plated ingredient cost. Don't forget yield loss: a raw fish fillet loses 15 percent to skin and bones, so the usable yield is 85 percent. Then divide the plated cost by the menu price to calculate food cost percentage. Target food costs range from 28 to 35 percent in fine dining, 30 to 40 percent in casual restaurants.
â–¶What is a yield percentage and why does it matter?
Yield percentage is the percentage of the original ingredient that is usable after trimming and cooking. A raw chicken has a 75 percent yield (25 percent bones, skin, trim). A salmon fillet has an 85 percent yield (15 percent loss to skin and bones). A vegetable like carrot has a 90 percent yield (10 percent loss to peeling and trim). If a recipe calls for 8 oz of salmon and you order one pound (16 oz), you need to account for the 15 percent loss: 16 oz Ă— 0.85 = 13.6 oz usable, so you'd need to order 19 oz to get 16 oz usable. Ignoring yield costs money and causes over-ordering. Every ingredient on your menu should have a documented yield percentage.
â–¶How do I price a dish so it is profitable but not absurdly expensive?
Use the target food cost percentage method. If your restaurant targets 32 percent food cost, divide the dish's ingredient cost by 0.32 to find the menu price. Example: a dish with $6 ingredient cost Ă· 0.32 = $18.75 menu price. If the market won't pay $19 for that dish, you either need to reduce costs (cheaper ingredients, smaller portion) or reconsider the dish. Never price based on what you think customers will pay; that often results in margins that are too thin. Price based on your target food cost, then test with customers. If a dish doesn't sell, it may be overpriced, poorly positioned on the menu, or not compelling to your customer base. Adjust one variable at a time (price, portion, ingredient) to diagnose the problem.
â–¶What is menu engineering and how do I use it to increase profitability?
Menu engineering divides dishes into four categories: stars (high profit, high popularity—keep and promote), plowhorses (high popularity, low profit—raise price or reduce cost), puzzles (high profit, low popularity—reposition or reprice to boost sales), and dogs (low profit, low popularity—remove or overhaul). Analyze sales data and profitability by dish, then apply the matrix. Stars deserve prime placement and spotlight; plowhorses need a price increase or cost reduction; puzzles might need a better menu description or repositioning near a star; dogs should be removed unless they serve a strategic purpose (vegetarian option, dietary need). This data-driven approach to menu design can improve profitability by 10 to 20 percent without changing the menu fundamentally.
â–¶How do I factor in labor and overhead when calculating the true cost of a dish?
Ingredient cost is only part of the picture. Add labor cost (estimated time to prep, cook, plate) and overhead (rent, utilities, labor, equipment depreciation) to get the true cost. Many restaurants use a multiplier method: ingredient cost Ă— 2.8 to 3.5 = menu price (this accounts for labor, overhead, and profit margin). Others allocate a percentage of labor and overhead to each dish based on complexity. A simple grilled fish might have 15 minutes of labor; a multi-component dish might have 45 minutes. Track prep time, cooking time, and plating time for each dish, then assign a labor cost based on your kitchen's hourly labor rate. True cost = ingredient cost + allocated labor + allocated overhead. Menu price should be set so true cost is 60 to 70 percent of the selling price, leaving 30 to 40 percent for profit and waste.
â–¶How do I handle seasonal ingredient changes and adjust pricing?
Seasonal ingredients vary in price: asparagus is cheap in spring and expensive in winter. Build a seasonal ingredient calendar showing when each ingredient is in season and at peak price. When an ingredient goes out of season and the price spikes, either substitute a cheaper seasonal alternative (winter squash for summer tomato), adjust the portion (smaller portion = lower cost), or raise the menu price by 10 to 15 percent. Explain seasonal pricing to staff so they can explain it to customers with confidence. Customers understand and accept seasonal pricing if it is positioned as 'we use the best, seasonal ingredients.' Consider a 'seasonal market price' section on the menu for high-volatility ingredients (seafood, game) so you can adjust price without reprinting the menu.
â–¶How do I prevent food waste and manage portion control?
Define portion sizes by weight or count (6 oz steak, 3 oz sauce, 5 asparagus spears), not by eye. Train staff to measure portions consistently. Use portion scales and serving utensils of standard sizes (a 2 oz ladle, a 4 oz spoon) to enforce consistency. Standardize recipes and train junior cooks to follow them exactly. Track waste daily: every plate sent back, every prep item spoiled, every mistake that goes in the trash is lost profit. Implement a 'family meal' system so trim and off-cuts are used for staff meals rather than thrown away. Review waste reports weekly and investigate spikes. A 3 percent waste rate is acceptable; over 5 percent is a problem worth investigating. Small changes in portion control and waste reduction can improve margins by 2 to 5 percent.
