Controlling Restaurant Food Cost: Target Percentages and Strategies
How to calculate, track, and reduce food costs in a restaurant - including ideal percentages, recipe costing, menu engineering, and waste reduction.
Food cost is the single most controllable expense in a restaurant and one of the biggest determinants of profitability. A 2-percentage-point improvement in food cost on $1 million in revenue is $20,000 straight to the bottom line.
What Is Food Cost Percentage?
Food cost percentage = (Cost of Goods Sold / Food Revenue) x 100
If you spent $28,000 on food and generated $90,000 in food revenue this month: $28,000 / $90,000 = 31.1% food cost
Target Food Cost by Restaurant Type
| Restaurant Type | Target Food Cost |
|---|---|
| Fine dining | 28–35% |
| Casual dining | 28–32% |
| Fast casual | 25–30% |
| Quick service / Fast food | 25–30% |
| Pizza | 20–28% |
| Bakery / Café | 25–35% |
| Bar / Pub (food) | 30–35% |
| Bar / Pub (beverages) | 18–24% |
| Catering | 28–33% |
The industry-wide average is roughly 28–35% for food and 18–24% for beverages. Your blended cost (food + beverage combined) should ideally land at 28–32%.
How to Calculate Food Cost (Two Methods)
Method 1: Period Food Cost
The most common method. Take a time period (week or month) and calculate:
Food Cost = (Beginning Inventory + Purchases - Ending Inventory) / Food Sales
Example:
- Beginning inventory: $12,000
- Purchases during month: $25,000
- Ending inventory: $10,000
- Food sales: $90,000
Food cost = ($12,000 + $25,000 - $10,000) / $90,000 = $27,000 / $90,000 = 30.0%
Method 2: Plate Cost (Per-Item)
Calculate the cost to produce each individual menu item:
Plate cost = Sum of all ingredient costs for one serving
Item food cost % = Plate cost / Menu price x 100
Example - Grilled Salmon Plate:
- Salmon fillet (6 oz): $4.20
- Asparagus (4 oz): $0.80
- Rice pilaf (6 oz): $0.45
- Lemon butter sauce (2 oz): $0.35
- Garnish: $0.20
- Total plate cost: $6.00
- Menu price: $22.00
- Item food cost: 27.3%
Recipe Costing: Getting It Right
Accurate recipe costing requires precision. Here’s the process:
Step 1: Standardize recipes
Write down exact quantities for every ingredient in every dish. No “a handful of” or “season to taste” - use weights and measures.
Step 2: Calculate cost per usable unit
Ingredients have waste. A case of lettuce heads has an outer layer you remove. Account for yield percentage:
- Whole chicken: 65% yield (bones, skin, fat)
- Lettuce heads: 75% yield (outer leaves, core)
- Shrimp (head-on): 50% yield (head, shell)
- Onions: 90% yield (skin, ends)
Cost per usable ounce = Purchase price / (Purchase weight x Yield %)
A 10 lb case of shrimp at $80: $80 / (160 oz x 0.50) = $1.00 per usable ounce.
Step 3: Cost each ingredient in the recipe
Multiply the cost per usable unit by the quantity used in the recipe.
Step 4: Add a waste/spillage factor
Even with accurate yield percentages, there’s additional waste from dropped plates, mistakes, and over-portioning. Add 2–5% to your calculated plate cost as a buffer.
Menu Engineering: Maximizing Profitability
Menu engineering classifies items by two dimensions: popularity (how often they sell) and profitability (contribution margin in dollars).
The Four Categories
Stars - High popularity, high profit. These are your best items. Feature them prominently. Don’t change them.
Plowhorses - High popularity, low profit. Customers love them, but they don’t make you much money. Strategies: reduce portion size slightly, substitute cheaper ingredients, raise the price modestly.
Puzzles - Low popularity, high profit. Great margins, but nobody orders them. Strategies: rename them, reposition them on the menu, have servers recommend them, add better descriptions.
Dogs - Low popularity, low profit. Consider removing them. They take up menu space, require ingredient inventory, and contribute little.
Menu Design Tricks
The “Golden Triangle”: When people open a menu, their eyes go to the middle first, then upper right, then upper left. Place your highest-margin items there.
Decoy pricing: Including one very expensive item makes everything else seem reasonable. A $65 steak makes a $32 fish dish feel like a moderate choice.
Remove dollar signs: Studies show removing the ”$” symbol and writing “22” instead of “$22.00” reduces price sensitivity.
Strategic descriptions: “Pan-seared Atlantic salmon with roasted garlic asparagus and herbed rice pilaf” sells better and justifies a higher price than “Salmon plate.”
Waste Reduction Strategies
The National Restaurant Association estimates that restaurants waste 4–10% of the food they purchase. Reducing waste directly improves food cost.
Track waste daily
Keep a waste log in the kitchen. Every time food goes in the trash - burned items, dropped plates, expired ingredients, over-production - write it down. What gets measured gets managed.
First In, First Out (FIFO)
Always use older inventory before newer inventory. Label everything with received dates. New deliveries go behind existing stock. This prevents spoilage.
Prep only what you need
Over-prepping is one of the biggest waste sources. Track daily usage patterns and prep accordingly. It’s better to run out of prep 30 minutes before close than to throw out a full container every day.
Cross-utilize ingredients
Design your menu so that ingredients appear in multiple dishes:
- Roasted chicken appears in salads, sandwiches, and as an entree
- Excess bread becomes croutons or bread pudding
- Vegetable trim goes into stock
- Berry garnishes reappear in desserts
Negotiate with suppliers
- Compare prices from at least 3 distributors quarterly
- Buy seasonal produce when it’s abundant and cheap
- Consider group purchasing organizations (GPOs) for better volume pricing
- Check if you’re paying for features you don’t need (pre-cut vegetables vs. whole)
Portion Control
Inconsistent portioning is a silent profit killer. If your recipe calls for 6 oz of salmon and cooks routinely plate 7–8 oz, you’re giving away 15–30% extra food cost on that item.
Solutions:
- Use scales, scoops, ladles, and portion cups - not eyeball estimates
- Post portioning guides with photos at prep stations
- Weigh proteins as they’re plated
- Audit portion sizes weekly by weighing random plates
A 1 oz overpour on a 6 oz salmon portion at $0.70/oz costs $0.70 extra per plate. At 50 plates per day, that’s $35/day or $12,775/year - from one menu item.
Monitoring and Adjustments
Weekly food cost tracking
Don’t wait for month-end. Calculate food cost weekly:
- Count inventory every Sunday
- Add purchases received that week
- Subtract ending inventory
- Divide by food revenue for the week
Investigate variance immediately
If your target is 30% and you hit 34% one week, don’t wait to see if it corrects. Dig in immediately:
- Did a price increase hit from a supplier?
- Was there a catering event that skewed the numbers?
- Did waste spike?
- Were there inventory counting errors?
Adjust menu prices
Food costs rise. Your menu prices must keep pace. Review menu pricing quarterly against current ingredient costs. A 5% increase in food costs without a corresponding price increase can erase your entire net profit margin.
Price increase strategy: Raise prices on your most popular items by small amounts ($0.50–$1.00). Customers rarely notice small increases on items they order habitually. Avoid raising prices on price-sensitive items like basic burgers or lunch specials - instead, find savings through ingredient substitution or reduced portion sizes.
The Goal
A well-run restaurant maintains food cost within 1 percentage point of its target, week over week. Getting there requires standardized recipes, disciplined portioning, smart purchasing, waste tracking, and menu engineering. None of these individually transform your margins, but together they compound into the difference between a profitable restaurant and one that barely survives.
