How to Calculate Food Cost Percentage

Food cost percentage measures what portion of your sales revenue goes toward the ingredients for those dishes. **The Basic Formula**: Food Cost Percentage = (Total Food Costs / Total Food Sales) × 100 If you spend £3,000 on ingredients and sell £10,000 worth of food, your food cost percentage is 30%. **Why It Matters**: This number directly impacts your profitability. A restaurant with a 35% food cost has more money for labour, rent, and profit than one at 40%. Small percentage changes mean significant money over time. **Different Ways to Measure**: - **Actual Food Cost**: What you actually spent vs. what you actually sold (accounts for waste, theft, comps) - **Theoretical Food Cost**: What you should have spent based on recipes and sales (perfect-world scenario) - **Per-Item Food Cost**: Cost of ingredients for a specific dish vs. its selling price Most restaurants track all three to identify where problems occur.

Before calculating overall food cost, you need to know what each dish costs to make. **Step 1: List All Ingredients** For your signature burger: bun, beef patty, cheese, lettuce, tomato, onion, pickles, sauce. **Step 2: Determine Cost Per Unit** Find what you pay for each ingredient per usable unit. If a case of 24 buns costs £12, each bun costs £0.50. **Step 3: Account for Yield** A 500g beef portion might come from 600g raw weight after trimming and cooking loss. Calculate the cost based on usable yield, not purchase weight. **Step 4: Add It Up** Sum the cost of all ingredients in the recipe. If your burger costs £3.50 in ingredients and sells for £12, your per-item food cost is 29%. **Recipe Costing Example**: | Ingredient | Cost | |------------|------| | Bun | £0.50 | | 200g Beef Patty | £1.80 | | Cheese (2 slices) | £0.30 | | Lettuce, tomato, onion | £0.40 | | Sauce, pickles | £0.25 | | **Total** | **£3.25** | Selling at £12: Food cost = 27%

Target food cost varies significantly by restaurant type: **Quick Service / Fast Food**: 25-30% Lower prices require tighter control. High volume compensates for lower margins per item. **Casual Dining**: 28-32% The most common range. Allows for reasonable quality while maintaining margins. **Fine Dining**: 32-38% Premium ingredients justify higher food costs, but higher prices maintain profitability. **Pizza Restaurants**: 28-32% Flour and basic toppings are cheap, but premium pizzas may have higher costs. **Steakhouses**: 35-40% Protein-heavy menus naturally have higher food costs. Compensate with high drink margins. **Beverage Costs** (tracked separately): - Alcohol: 18-24% - Coffee: 15-20% - Soft drinks: 10-15% **Combined Cost**: Many restaurants target a combined food and beverage cost of 30-35%.

Your actual food cost accounts for everything that happened—waste, theft, mistakes, and comps. **The Formula**: Actual Food Cost = (Beginning Inventory + Purchases - Ending Inventory) / Food Sales × 100 **Example**: - Beginning inventory: £5,000 - Purchases during period: £8,000 - Ending inventory: £4,500 - Food sales: £28,000 Cost of Goods Sold = £5,000 + £8,000 - £4,500 = £8,500 Food Cost % = £8,500 / £28,000 × 100 = 30.4% **Why Actual Differs from Theoretical**: - **Waste**: Spoilage, over-preparation, dropped dishes - **Theft**: Employee or customer theft - **Portion Variance**: Servers or kitchen giving larger portions - **Recipe Non-Compliance**: Not following standardised recipes - **Comps and Discounts**: Free food that still cost you ingredients A gap of 1-2% between theoretical and actual is normal. Larger gaps signal problems needing investigation.

When food cost is too high, here's where to look: **Menu Engineering**: Remove or reprice dishes with poor margins. Promote dishes that sell well AND have good margins. **Portion Control**: Standardise portions with measuring tools, scales, and portioning equipment. A few grams extra per plate multiplies across hundreds of covers. **Waste Reduction**: Track what's being thrown away. If lettuce spoils weekly, order less or find more uses for it. FIFO (First In, First Out) prevents expiration. **Supplier Negotiation**: Get competing quotes. Negotiate better prices, especially for high-volume items. Consider supplier consolidation for better terms. **Cross-Utilisation**: Use ingredients across multiple dishes. If you buy whole chickens, use breasts for one dish, thighs for another, bones for stock. **Batch Cooking**: Prep efficiently. Cooking 20 portions is more efficient than cooking 5 portions four times. **Theft Prevention**: Locks on storage, security cameras, and inventory tracking reduce both internal and external theft. **Recipe Adherence**: Train kitchen staff on exact recipes. Consistent execution means consistent costs.

Food cost is a key input for menu pricing, but not the only factor. **Food Cost Pricing Method**: Selling Price = Ingredient Cost / Target Food Cost % If a dish costs £4.50 in ingredients and you want a 30% food cost: Selling Price = £4.50 / 0.30 = £15.00 **But Consider**: - **Market Rates**: What do competitors charge for similar dishes? You may need to adjust. - **Perceived Value**: Some ingredients justify premiums. A £3 salad can sell for £12 with the right positioning. - **Price Points**: £14.95 feels different from £15.00. Round to psychology-friendly numbers. - **Menu Balance**: You need some lower-priced options. Compensate with higher-margin drinks or sides. **Contribution Margin vs. Food Cost %**: A dish with 35% food cost might contribute more pounds than one at 25% if the 35% item sells for much more. Consider absolute margin, not just percentage. | Dish | Cost | Price | Food % | Gross Profit | |------|------|-------|--------|--------------| | Salad | £2 | £9 | 22% | £7 | | Steak | £12 | £32 | 37.5% | £20 | The steak has worse food cost % but contributes more profit.
