What is food cost?

Food cost represents the total amount of money your restaurant spends on ingredients and food products during a specific period. This includes everything from raw ingredients like meat, vegetables, and spices to pre-prepared items you purchase from suppliers.

It’s important to distinguish between food cost and Cost of Goods Sold (COGS). While related, COGS encompasses all direct costs associated with producing your menu items, including food, beverages, and sometimes paper goods or disposables. Food cost specifically focuses on edible ingredients.

Your food cost calculation should include:

• Raw ingredients and produce
• Meat, poultry, and seafood
• Dairy products
• Spices, seasonings, and condiments
• Oils, vinegar, and cooking essentials
• Bread and bakery items

Exclude from food cost calculations:

• Labor costs
• Rent and utilities
• Equipment depreciation
• Cleaning supplies
• Paper products (unless included in COGS strategy)

What is food cost percentage?

Food cost percentage is a key performance indicator that shows what portion of your food revenue goes toward purchasing ingredients. Expressed as a percentage, it helps you understand how efficiently you’re managing your food budget relative to your sales.

This metric serves as a benchmark for comparing performance across different periods, identifying trends, and making informed decisions about menu pricing and cost control measures.

Do this before you start food costing

Before diving into food cost calculations, establish a solid foundation with these essential steps:

Implement comprehensive accounting systems. Accounting software helps manage your books, records, inventory, and transactions with speed and accuracy. If your POS system includes inventory management capabilities that track purchases and stock levels, sync this data with your accounting software for seamless financial oversight. Consider ETM’s EPOS solutions for integrated restaurant management that simplifies this process.

Track all your numbers consistently. Whether through automated POS systems or manual tracking, monitor your prime cost (the ratio between sales and total cost of goods sold plus labor). This metric provides crucial insight into your operational efficiency.

Define your accounting period. Most restaurants operate on four-week accounting cycles, but choose whatever timeframe makes sense for your business model and cash flow patterns. Consistency in your chosen period is more important than following industry norms.

Set realistic budget targets. Budgets shouldn’t merely reflect current performance but should guide your restaurant toward maximum efficiency. Establish targets that challenge your team while remaining achievable based on historical data and market conditions.

Focus on weekly operational budgets. While high-level monthly or quarterly views matter for strategic planning, weekly budgets provide granular operational control. Smaller timeframes make expense tracking more manageable and allow for quicker adjustments when needed.

Set up proper inventory systems. Implement systematic ingredient tracking from delivery to plate, including organized storage, clear labeling, and regular inventory counts.

Create standardized recipes. Document exact ingredient quantities, preparation methods, and portion sizes for every menu item. Recipe consistency ensures accurate cost calculations and maintains food quality standards.

Establish reliable supplier relationships. Build partnerships with food suppliers who provide consistent pricing and quality. Stable supplier relationships improve forecasting accuracy and budget planning.

Once your comprehensive budgeting system is firmly established, you can confidently begin detailed food costing calculations.

Calculating food cost percentage

The food cost percentage formula is straightforward but requires accurate data collection:

Food Cost Percentage = (Total Food Costs ÷ Total Food Revenue) × 100

To calculate this accurately, follow these steps:

Step 1: Determine your time period. Choose a consistent timeframe (weekly, monthly, or quarterly) for all calculations.

Step 2: Calculate total food costs. Add up all money spent on food ingredients during your chosen period. Include invoices, receipts, and any food-related purchases.

Step 3: Record total food revenue. Use your POS system to determine total food sales (excluding beverages, if calculated separately) for the same period.

Step 4: Apply the formula. Divide total food costs by total food revenue, then multiply by 100 to get your percentage.

For restaurants using integrated EPOS systems, much of this data collection happens automatically, reducing manual calculation errors and saving valuable time.

Example food cost calculation

Time period: March 2025 (one month) Total food purchases: £8,500 Total food revenue: £28,000

Calculation: Food Cost Percentage = (£8,500 ÷ £28,000) × 100 = 30.36%

This means approximately 30% of the food revenue was spent on ingredients during March. Whether this percentage is acceptable depends on several factors, including restaurant type, location, and target profit margins.

Find your ideal food cost percentage

Your ideal food cost percentage depends on multiple factors:

Restaurant type matters significantly. Fast-casual establishments typically operate with higher food cost percentages (28-32%) because they rely on volume and operational efficiency. Fine dining restaurants, on the other hand, often maintain 30-40% due to higher menu prices.

Location affects costs and pricing. Urban restaurants may have higher ingredient costs but can charge premium prices. Suburban locations might have lower costs but face more price-sensitive customers.

Menu composition influences percentages. Restaurants heavy on expensive proteins will naturally have higher food cost percentages than those featuring pasta or vegetable-based dishes.

Business models impact targets. Fast-food chains might operate efficiently at 30-32%, while upscale establishments target up to 32%.

What is a good food cost percentage?

Industry benchmarks provide helpful guidance:

28-32% – Acceptable range for most casual dining establishments 25-30% – Target range for fast-casual restaurants 20-25% – Typical for fine dining establishments 30-35% – Common for pizza shops and sandwich shops

Remember that these are general guidelines. Your specific circumstances, including local market conditions, competition, and business model, will influence what percentage works best for your operation.

Monitor trends rather than focusing solely on hitting a specific number. A restaurant consistently maintaining 31% might outperform one fluctuating between 25% and 35%.

Calculating food cost per serving

Understanding cost per serving helps with menu pricing and portion control. This calculation breaks down the total cost of ingredients for individual dishes.

Food cost per serving formula

Food Cost Per Serving = Total Recipe Cost ÷ Number of Servings

To calculate recipe cost:

1. List all ingredients with exact quantities
2. Determine the cost of each ingredient per unit
3. Calculate the cost for the quantity used in the recipe
4. Sum all ingredient costs

Example calculation for cost per serving

Recipe: Chicken Caesar Salad (serves 4)

Ingredients and costs:

• Chicken breast (8 oz): £3.20
• Romaine lettuce (1 head): £1.50
• Parmesan cheese (2 oz): £2.00
• Caesar dressing (4 tbsp): £0.80
• Croutons (1 cup): £0.60
• Anchovies (4 fillets): £0.40

Total recipe cost: £8.50 Servings: 4 Cost per serving: £8.50 ÷ 4 = £2.13

This means each Chicken Caesar Salad costs £2.13 in ingredients. If you’re targeting a 25% food cost percentage, you should price this dish around £8.50 (£2.13 ÷ 0.25).

Why is food cost percentage important?

Food cost percentage serves multiple critical functions in restaurant management:

Profit protection comes first. By monitoring this metric, you quickly identify when costs are eating into profits, allowing for immediate corrective action.

Pricing decisions become data-driven rather than guesswork. Understanding your actual costs enables confident menu pricing that ensures profitability.

Trend identification helps spot problems early. Rising food cost percentages might indicate supplier price increases, portion control issues, or theft.

Benchmarking performance allows comparison with industry standards and your own historical data. This insight guides strategic decisions about menu changes, supplier negotiations, and operational improvements.

Budget planning becomes more accurate when you understand historical cost patterns and can forecast future expenses with greater precision.

How to lower food costs in your business

Reducing food costs requires a strategic approach across multiple areas:

Menu engineering offers immediate impact. Analyze each dish’s profitability and popularity. Eliminate low-margin, unpopular items and promote high-margin favorites. Consider replacing expensive ingredients with cost-effective alternatives that maintain quality.

Supplier relationship management can yield significant savings. Build strong partnerships with reliable suppliers, negotiate better prices for consistent orders, and explore group purchasing opportunities with other local restaurants.

Inventory optimization prevents waste and reduces carrying costs. Implement first-in-first-out (FIFO) rotation, maintain optimal stock levels, and track waste to identify problem areas.

Portion control ensures consistency and prevents over-serving. Use standardized recipes, train staff on proper portioning, and regularly audit plate presentations.

Staff training on food handling and preparation reduces waste through proper techniques and awareness of food cost impact.

Technology integration through modern POS and inventory systems provides real-time cost tracking and automated reporting capabilities.

How to use food cost percentage to set menu prices

Food cost percentage provides the foundation for strategic menu pricing:

Start with your target percentage. If you’re aiming for 25% food cost, divide your ingredient cost by 0.25 to determine minimum menu price.

Consider market factors. Research competitor pricing and customer price sensitivity in your market. Your calculated price might need adjustment based on local conditions.

Account for all costs. Remember that menu prices must cover more than just food costs. Factor in labor, overhead, and desired profit margins.

Test and adjust. Implement new prices gradually and monitor customer response. Small adjustments often work better than dramatic changes.

Regular reviews ensure your pricing stays aligned with changing costs and market conditions.

Managing food cost for better margins

Effective food cost management requires ongoing attention and systematic approaches:

Weekly cost analysis helps maintain control. Review food cost percentage weekly to catch trends early and make timely adjustments.

Seasonal menu planning takes advantage of ingredient price fluctuations. Design menus around seasonal availability to minimize costs while maximizing freshness.

Waste tracking identifies improvement opportunities. Monitor what gets thrown away and why, then address root causes through better planning, training, or menu adjustments.

Regular recipe costing ensures prices remain profitable as ingredient costs change. Update calculations quarterly or when major price changes occur.

Performance monitoring through consistent measurement and analysis helps maintain target percentages and identify successful strategies.

Key Takeaways:

• Master the formula: Food Cost Percentage = (Total Food Costs ÷ Total Food Revenue) × 100. Success depends on consistent application and accurate data collection.
