In the first half of 2025, an average of two licensed venues closed permanently each day in the UK. Food costs didn’t sink all of them, but for restaurants where every percentage point counts, the difference between profit and loss often comes down to how tightly they manage what goes into each dish and what they pay for it. This article outlines 20 strategies for controlling restaurant food costs, covering ways to improve tracking and analysis, optimise operations and make smarter supplier and pricing decisions.
What Are Restaurant Food Costs?
Restaurant food costs refer to the total expense associated with purchasing, storing and preparing food for menu items. This includes waste and spoilage, but beverage costs are typically tracked separately.
Food costs are commonly measured as a percentage of total food sales to assess efficiency and profitability.
Key Takeaways
- Food costs typically represent around a third of restaurant revenue and are one of the largest expenses restaurateurs can directly control.
- A food cost percentage between 28% and 35% is typical for UK restaurants, though the right target depends on concept and service style.
- Portion control, waste reduction and supplier management can materially improve food-cost performance.
- Accurate inventory management is essential. Without it, the gap between what you should be spending and what you are spending stays hidden.
Why Are Restaurant Food Costs Important for Restaurant Owners?
Unlike rent, rates or energy, food costs are one of the few major expenses restaurant operators can actively control. And because food typically represents the largest variable cost, even small improvements in cost management translate directly to the bottom line. Understanding and managing these costs is essential for pricing menu items accurately, reducing waste and protecting profit margins.
But not every factor affecting food costs is within a restaurateur’s control. The UK produces only around 53% of its vegetable supply and just 16% of its fruit domestically. This means menus heavy in fresh produce are exposed to crop-yield fluctuations, freight costs, currency fluctuations and border friction — all of which directly affect ingredient prices.
Key Elements of Restaurant Food Costs
Restaurant food costs include more than ingredients. Waste and spoilage, for instance, count towards what a restaurant spends on food. Other expenses, like packaging and delivery fees, don’t factor into food costs, but they do affect the profitability of each sale, so they’re worth tracking alongside food costs.
- Ingredients: These are raw materials used to prepare menu items, including meat, produce, dairy and dry goods. ONS Producer Price data shows domestic food inputs rose 4.2% year-on-year in October 2025, while imported food inputs increased 1.1% over the same period — a reminder that UK-sourced and imported ingredients can behave very differently. Category-specific volatility also matters. Avian flu, for example, has disrupted UK poultry markets and pushed prices up.
- Beverages: Drinks used in cooking (such as wine in a sauce, beer in a batter, coffee in a glaze) count as food costs. Beverages sold to customers are typically tracked separately as beverage costs. Some operators lump them together, though most keep them distinct for clearer margin analysis.
- Waste and spoilage: Food lost before it reaches a customer. Common causes include over-ordering, improper storage, preparation trim and errors, and unsold dishes. Each represents an opportunity to tighten controls and recover margins.
- Packaging and containers: Takeaway packaging, containers and disposables add to the cost of each order but aren’t factored into food cost percentage. These costs have increased due to sustainability requirements and regulatory changes.
- Delivery charges: Supplier delivery fees and fuel surcharges that are part of acquiring ingredients factor into food costs. Third-party platform commissions, which can range from 15% to 35%, are different: they’re selling expenses, not food costs, but they significantly affect per-order profitability for restaurants offering delivery.
How Do You Calculate Your Restaurant Food Cost Percentage?
Food cost percentage measures how much of your total food sales revenue is spent on food. This metric helps operators understand whether their pricing, purchasing and portion control are aligned with profitability targets. The standard formula is:
Food cost percentage = (Cost of goods sold / Total food sales) × 100
Cost of goods sold (COGS) includes opening inventory, plus purchases during the period, minus closing inventory.
Suppose a pub had £5,000 in inventory at the start of the month, purchased £12,000 in food supplies during the month, and had £4,000 remaining at month’s end. Its COGS would be £13,000 (£5,000 + £12,000 – £4,000). If total food sales for that month were £40,000, food cost percentage would be 32.5% (£13,000 / £40,000 × 100).
Calculating Restaurant Food Cost Per Serving
While food cost percentage shows overall efficiency, food cost per serving tells you what each dish actually costs to produce, essential insight for pricing decisions and identifying which menu items are most profitable.
To calculate it, divide the total cost of ingredients used in a recipe by the number of portions produced. For example, if the pub’s fish and chips dish uses £1.80 in cod, £0.65 in potatoes and oil, £0.31 in batter ingredients and £0.25 in garnishes and condiments, the total ingredient cost is £3.01 per serving. If the dish is sold for £12.95, it represents a 23% food cost for that specific item — notably better than the overall 32.5% food cost percentage. This suggests it’s a profitable menu item worth promoting.
Recipe costing should account for all ingredients, including garnishes, seasonings and cooking oils, to provide a complete picture of dish profitability.
What Is a Good Food Cost Percentage?
Industry benchmarks suggest a food cost percentage of around 28% to 35% is typical for restaurants, though this varies by concept and service style.
Quick-service restaurants often operate at the lower end of the range, while casual dining typically falls in the middle. Fine-dining establishments may sit higher due to premium ingredients and elaborate presentations. Pubs with food service often achieve lower food cost percentages because higher beverage margins offset food expenses.
These benchmarks should be viewed as guidelines rather than strict rules, as there is no single official benchmark for ideal food cost percentage by restaurant type. The key is to understand your own cost structure, track performance over time and adjust as ingredient prices and menu offerings change.
20 Strategies for Controlling Restaurant Food Costs
Controlling food costs requires a combination of operational discipline, data visibility and strategic decision-making. The following strategies can help restaurateurs identify savings opportunities and protect margins in a challenging market.
-
Map Restaurant Expenses
Create a clear breakdown of all food-related expenses, from ingredients and beverages to packaging and delivery charges, to understand where money is being spent. Categorise costs using accounting software or spreadsheets and calculate each category as a percentage of revenue to identify areas that exceed industry benchmarks.
-
Compare Actual Costs to Theoretical Costs
Regularly compare actual food costs against theoretical recipe costs to identify discrepancies caused by waste, portioning issues or pricing changes. Actual food cost reflects what you are spending, while theoretical cost represents what you should be spending based on recipes and sales data. A significant gap between the two signals opportunities for improvement.
-
Uncover Hidden Expenses
Ingredient prices are easy to track, but other costs can go unnoticed. Minimum order fees, late delivery penalties, stock write-offs, credit card processing fees and third-party delivery commissions all cut into margins. So does employee turnover, which is estimated to cost thousands of pounds per position. Build a regular review of these expenses into your financial process so they don’t quietly hurt profitability.
-
Optimise Stock with FIFO
First-in, first-out (FIFO) is a simple principle: use older stock before what was delivered most recently. In practice, it requires clear labelling, organised storage and staff who understand why stock rotation matters. Done consistently, FIFO keeps ingredients from expiring before they’re used, meaning less money in the bin.
-
Opt for Seasonal Ingredients
UK-grown seasonal produce tends to cost less and arrive fresher than imported alternatives, helping to lower costs and improve menu appeal. Building menus around seasonal, domestic availability lessens reliance on imported or out-of-season items, which often carry higher prices and greater supply volatility. Given the UK's relatively low domestic production of fruit and vegetables, seasonal menu planning can also alleviate exposure to import-related cost fluctuations.
-
Maintain Ingredient Quality Control
Set clear specifications for ingredients and approve suppliers who can meet them consistently. This won’t eliminate price or quality fluctuations, but it establishes a baseline to measure against — and grounds to push back when deliveries fall short. Inspect deliveries on arrival to verify quantity, quality and temperature compliance. Reject substandard products immediately to avoid waste from spoiled or unusable ingredients.
-
Run Specials to Move Stock
The Waste and Resources Action Programme (WRAP) estimates food waste costs the UK hospitality sector £3.2 billion annually. Daily or weekly specials can help slash that figure by moving surplus inventory before it spoils. Ingredients approaching their use-by date become profitable dishes instead of waste.
-
Control Portion Sizes
A dish that’s portioned inconsistently is costed inconsistently, and what looks like a 30% food cost on paper might be 35% on the plate. Standardised measuring tools, scales and portion scoops help control food usage and close that gap. Visual guides for kitchen staff can reinforce plate size and presentation standards to maintain consistency, especially when plating can vary between cooks or locations.
-
Consider Recipe Costing
Accurate recipe costing allows restaurants to understand what each menu item actually costs to produce, but it only works if costs are kept current. Update recipe costs when ingredient prices change, and make sure everything is accounted for — garnishes, seasonings and cooking oils add up faster than you might expect.
-
Improve Your Menu Price Strategy
Price menu items based on both food cost percentage and perceived value, rather than applying a single margin to the whole menu. A lower-margin dish that draws customers in, say a popular burger, can be offset by higher-margin sides, drinks or desserts they order alongside it. Menu-engineering helps identify which items play which role: what’s profitable, what’s popular and what might need repricing or removal.
-
Remove Low-Performing Menu Items
Analyse sales data to identify menu items that aren’t earning their keep, whether due to low demand, low margins or ingredients that nothing else on the menu uses. Removing or reworking these items reduce inventory complexity and waste. Plus, a leaner menu can simplify prep and speed up service.
-
Negotiate Prices with Suppliers
Regularly review pricing with suppliers, particularly for high-volume ingredients, and ask for volume-based discounts where possible. A 2% reduction on an ingredient you order weekly adds up faster than a 10% reduction on something you order twice a year. Request price matching if competitors offer lower rates and explore early payment discounts if cash flow allows.
-
Consider Switching Suppliers
Benchmark suppliers periodically to confirm that pricing remains competitive. Long-term relationships can earn you flexibility on payment terms, priority during shortages and advance notice on price changes; but those benefits are worth quantifying against what you’d save elsewhere. Request quotes from alternative suppliers annually, even if you don’t intend to switch. Knowing the options strengthens your position in negotiations.
-
Review Your Supplier Contracts
Supplier contracts can contain terms that quietly inflate food costs; price-escalation clauses, delivery charges and minimum-order requirements can all affect what you pay for ingredients. Review contracts regularly to understand what can be renegotiated and what notice periods apply. Catching an automatic price increase before it kicks in is easier than negotiating it back down after, for instance.
-
Strengthen Your Relationships With Suppliers
Suppliers who see you as a partner, not just another account, are more likely to hold pricing during volatile periods, warn you about upcoming shortages or prioritise your orders when supply is tight. That kind of goodwill is built over time. Take care to communicate openly, pay invoices on time and treat supplier conversations as cordial interactions rather than mere transactional opportunities.
-
Train Your Restaurant Staff
Untrained or undertrained staff cost you in ways that don’t show up immediately, whether due to over-portioned plates, spoiled ingredients from improper storage, prep waste or dishes that need to be re-fired. Even well-meaning habits add up. A server who thinks the standard portion of chips looks a bit stingy and adds a few extra inflates food costs, plate by plate. Training should cover food handling and storage, portion standards and waste awareness — including why those standards exist.
-
Discourage Food Theft
Theft in kitchens rarely looks like someone walking out with a case of steaks. More often it’s a handful of prawns here, an extra portion there or staff meals that exceed what’s agreed. These small losses can be hard to identify individually but show up as unexplained gaps between theoretical and actual food costs. Regular stocktakes, restricted storage access and clear policies regarding staff meals can help.
-
Implement Sales Forecasting
Over-ordering means spoilage; under-ordering means running out of dishes mid-service and disappointing customers. Accurate forecasting helps you hit the sweet spot. Historical sales data, local events, weather patterns and seasonal trends all affect how many covers to expect, so you can prep just enough. Modern forecasting tools can help you see patterns you’d otherwise miss, but even a well-maintained spreadsheet is better than guessing.
-
Automate Back-Office Processes
Manual purchasing, inventory tracking and financial reporting are time-consuming and prone to error. Inventory management software can track stock levels continuously and flag variances between theoretical and actual usage, problems that might otherwise go unnoticed until they’ve already affected margins. Automating these processes also frees staff time for work that directly serves customers.
-
Improve Stocktaking and Inventory Accuracy
Regular stocktakes and accurate inventory records show the difference between what you should have on hand and what you actually have. Without that, food cost calculations won’t reflect reality. Conduct stocktakes at consistent intervals: weekly for high-value or perishable items, monthly for full inventory. Accurate counts are essential for calculating actual food costs and catching discrepancies early.
Gain Visibility into Your Restaurant's Spending with NetSuite Financial Management
Restaurants that track food costs across multiple systems, like supplier invoices, POS reports and inventory spreadsheets, for example, know how much time it takes to pull everything together. NetSuite ERP for Restaurants simplifies financials, inventory management, menu pricing optimisation, demand analysis and supplier oversight. That means restaurant executives and owners have greater control over food and labour costs, healthier margins and real-time insights to stay ahead of the curve. For multi-location operators, consolidated dashboards make it easier to compare food cost performance between sites and spot variances before they spread.
When theoretical and actual costs live in the same system, the discrepancies that drive up food costs become much easier to catch. NetSuite Financial Management helps with this, bringing food costs, inventory and profitability into one integrated system to give restaurateurs a clearer picture of what’s going on without waiting for month-end reports.
Food costs are one of the few major expenses' restaurants can directly control but controlling them takes consistent attention. The strategies here cover tracking and analysis, kitchen operations, supplier management and pricing decisions. But none of them work as one-off fixes; it’s essential to build these practices into operations, not just when margins feel tight.
Restaurant Food Cost FAQs
How does food cost differ from prime cost?
Food cost covers only the cost of ingredients and beverages used in preparing menu items. Prime cost combines food cost with total labour costs (including wages, payroll taxes and benefits), providing operators with a view of their two largest and most controllable expense categories.
What are common food costing mistakes?
The most common mistakes come down to bad data: inaccurate inventory counts, inconsistent portions and recipe costs that haven't been updated since prices changed. Operators also tend to overlook smaller expenses: delivery fees, credit card processing charges and staff turnover that quietly add up. Without regular stocktakes, the gap between theoretical and actual spending stays hidden.
What is the formula for profit in a restaurant?
Profit is calculated by subtracting total costs, including food, labour and overheads, from total revenue. A simplified formula is: Profit = Total revenue – (Food costs + Labour costs + Overhead costs). This calculates operating profit. Overhead costs include rent, utilities, insurance, supplies, marketing and other operating expenses.
What is the 30/30/30/10 rule for restaurants?
The 30/30/30/10 rule is a budgeting guideline suggesting restaurants allocate approximately 30% of revenue to food costs, 30% to labour costs and 30% to overhead expenses (rent, utilities, equipment and other operating costs), with 10% leftover for profit. While useful as a starting framework, actual percentages vary by restaurant type and market conditions.
