Food cost tracking forms the backbone of any profitable restaurant operation. Too many owners operate blind to their actual dish costs, bleeding money without realizing it. Monthly monitoring can turn those hidden losses into visible profits.
Why tracking food cost is so important
Your kitchen's buzzing every night. Tables packed. But your bank account tells a different story at month's end.
The culprit? Untracked food costs. Not because your chef can't cook, but because nobody knows what each plate actually costs to make.
💡 Example:
You sell a ribeye for €32.00 (incl. 9% VAT):
Selling price excl. VAT: €29.36
Ingredient costs: €11.50
Food cost: 39.2% - dangerously high!
Most restaurants should hit 28-35% food cost. Above 35%? You're probably losing money on every plate.
What you need to get started
Monthly food cost tracking requires four key pieces:
- Recipes - exact quantities per dish
- Purchase prices - what you pay per kilo/liter
- Selling prices - what's on your menu
- Sales figures - how many of each dish you sell
⚠️ Important:
Always calculate with prices EXCLUDING VAT. Menu prices include 9% VAT for restaurant food. Divide by 1.09 for accurate calculations.
The basic formula you need to know
Food cost calculation is straightforward:
Food cost % = (Ingredient costs / Selling price excl. VAT) × 100
💡 Example calculation:
Pasta carbonara:
Menu price: €18.50 incl. VAT
Excl. VAT: €18.50 ÷ 1.09 = €16.97
Ingredient costs: €5.10
Food cost: (€5.10 ÷ €16.97) × 100 = 30.1%
Which dishes you should track
Don't track everything. Focus on these categories:
- Top 5 bestsellers - maximum impact on your bottom line
- Expensive ingredients - meat, fish, specialty products
- New dishes - verify your pricing assumptions
- Seasonal dishes - ingredient prices fluctuate
These 10-15 dishes control 80% of your food costs.
How often you should check
Monthly reviews work for most restaurants. But watch for these triggers that demand immediate checks:
- Supplier raises prices
- Season change (especially vegetables and fish)
- New chef or kitchen staff
- Sudden drop in profit
💡 Practical example:
Restaurant De Smaak checks every first Monday:
Food cost of 8 main dishes
Purchase prices for meat and fish
Previous month's sales figures
Two hours of work saves €300-500 monthly in waste.
Digital vs. manual tracking
Excel calculations eat up time. Digital tools automate the heavy lifting, but they're only as accurate as your data input.
Benefits of digital tracking:
- Automatic calculations
- All dishes visible at once
- Quick price updates
- Historical trends tracking
Remember: you still need to maintain current recipes and prices. No system runs itself.
Step-by-step implementation
Week 1: Gather your data
Collect your most important recipes first. Document everything - main ingredients down to herbs and garnish. Most restaurants forget small costs like cooking butter or salad oil. These add up fast.
Week 2: Inventory your prices
Review recent purchase invoices for current prices per kilo or liter. Use 3-month averages for reliable data. Include transport and admin costs - they're part of your true purchase price.
Week 3: First calculations
Start with your 5 bestsellers. Calculate precise cost per portion. Add 5-10% for waste - cutting losses and portioning variations are real costs.
Week 4: Set up monitoring system
Build a tracking system your team can actually use. Simple beats complex every time. Whether Excel or software, clarity matters most.
Practical example: Brasserie Het Plein
Brasserie Het Plein seats 45 and serves modern Dutch cuisine. Owner Marco watched profits shrink despite strong turnover. Monthly food cost tracking revealed the problems:
Problem 1: Beef tenderloin bleeding money
Beef tenderloin menu price: €28.50 (€26.15 excl. VAT)
Meat cost: €8.20
Side dish cost: €2.80
Total cost: €11.00
Food cost: 42.1% - unsustainable!
Solution: Raised price to €31.50 and reduced portion from 200g to 180g meat. New food cost: 35.8%
Problem 2: Fresh fish price volatility
Sole prices swung from €18 to €26 per kilo seasonally. Fixed menu price of €24.50 meant food costs bounced between 28% and 45%.
Solution: Introduced daily pricing and offered alternatives during high-price periods.
Result after 6 months:
Average food cost dropped from 38.2% to 31.5%. Same turnover, €1,200 extra monthly profit. This is a pattern we see repeatedly in restaurant financials - small adjustments compound into significant savings.
Common mistakes in food cost calculation
1. Forgetting small ingredients
Herbs, salt, pepper, cooking oil seem negligible per dish but quickly add 3-5% to costs. Always include a "miscellaneous" line of at least €0.50 per dish.
2. Using VAT-inclusive purchase prices
Business owners typically offset VAT on purchases but pay it on sales. Always compare net amounts for accurate calculations.
3. Ignoring waste
One kilo of potatoes doesn't yield one kilo peeled. Reality: 850-900g. Add 10-15% cutting loss for fresh products.
4. Using outdated prices
Food prices shift constantly. Three-month-old calculations might be completely wrong. Update monthly minimum - weekly for meat and fish.
5. Assuming perfect portions
Recipe calls for 150g beef, but actual portions range 140-170g. Calculate using real average portion sizes, not ideal targets.
Final thoughts
Monthly food cost tracking doesn't require complexity. Focus on your key dishes, maintain current prices, and apply the formula: Food cost % = (Ingredient costs / Selling price excl. VAT) × 100.
Start small with 5-10 dishes and expand gradually. Two hours monthly can save hundreds in costs. Most restaurants discover their food costs can drop 3-7% without quality compromises - just better portion awareness and price alignment.
Perfect food cost doesn't exist, but conscious tracking separates profitable kitchens from struggling ones.
How do you start with monthly food cost tracking?
Gather your recipes and prices
For your 5 best-selling dishes, write down exactly which ingredients go into them and what you pay for them. Include everything: main ingredients, garnish, sauces, oil and butter.
Calculate the cost price per dish
Add up all ingredient costs for one portion. Divide this by your selling price excluding VAT and multiply by 100 to get your food cost percentage.
Check which dishes are above 35%
Dishes with a food cost above 35% probably aren't profitable enough. Decide whether to make the portion smaller, use cheaper ingredients, or raise the price.
Plan your monthly check
Choose a fixed time (for example first Monday of the month) to check your food cost. Also check whether suppliers have raised prices since last month.
✨ Pro tip
Begin tracking your 3 highest-volume dishes within the next 7 days. If these stay under 33% food cost, you've secured most of your profit foundation.

Frequently asked questions
What if my food cost exceeds 35%?
You're likely losing money on that dish. Options include reducing portion size, substituting cheaper ingredients, or raising the selling price. Double-check that you've included all ingredient costs in your calculation.
How do I track supplier price increases?
Review invoices from major suppliers monthly, especially for meat, fish and dairy which fluctuate regularly. Many suppliers send updated price lists when changes occur, so file these systematically.
Should I calculate food cost including or excluding VAT?
Always exclude VAT from calculations. Menu prices include 9% VAT for food service. Divide menu prices by 1.09 to get the VAT-exclusive amount for accurate food cost percentages.
How long does monthly food cost tracking actually take?
Initial setup for 10 dishes takes 3-4 hours. After that, monthly tracking and updates require just 1-2 hours. Digital tools can cut this time significantly once you're established.
