Your food cost percentage reveals exactly how much of every sale goes toward ingredients. This metric directly impacts your bottom line and guides smarter pricing decisions. It's the foundation of profitable restaurant operations.
What is food cost percentage?
Your food cost percentage represents total ingredient spending as a portion of your sales revenue. It's your average ingredient cost across every dish you serve.
This metric reveals:
- How much of each euro in sales covers purchasing costs
- If your menu prices align with actual costs
- Opportunities to boost profitability through adjustments
The formula explained
The math is straightforward:
Food cost % = (Total ingredient costs / Total sales excl. VAT) × 100
⚠️ Important:
Always use sales EXCLUDING VAT in your calculations. Restaurant receipts include 9% VAT for food items.
💡 Example:
Restaurant The Taste generates €50,000 in March sales (incl. VAT):
- Sales excl. VAT: €50,000 / 1.09 = €45,872
- Ingredient costs: €14,500
- Food cost: (€14,500 / €45,872) × 100 = 31.6%
Every euro earned sends 32 cents to ingredient costs.
What counts as ingredient costs?
Include everything that directly enters your dishes:
- Primary ingredients: meat, fish, vegetables
- Accompaniments: potatoes, rice, sauces
- Cooking fats used in preparation
- Seasonings and spices
- Complimentary bread and butter
Exclude these items:
- Beverages (track separately with different margins)
- Cleaning products
- Paper goods and utensils
- Labor and overhead costs
Benchmark: what's normal?
Most restaurants operate between 28% and 35% food cost. Your restaurant type affects this range:
💡 Example by type:
- Pizzeria: 22-28% (low-cost base ingredients)
- Bistro: 28-32% (varied menu offerings)
- Fine dining: 30-35% (premium ingredients)
- Delivery restaurant: 28-35% (competitive pricing pressure)
If your percentage is too high
Exceeding 35%? You're likely hemorrhaging profits. From tracking this across dozens of restaurants, common culprits include:
- Oversized portions: kitchen staff exceeding recipe specifications
- Outdated pricing that hasn't kept pace with supplier increases
- Excessive waste from poor inventory management
- Premium ingredients without corresponding menu price adjustments
💡 Example impact:
Restaurant generating €500,000 annually:
- At 32% food cost: €160,000 ingredient spending
- At 37% food cost: €185,000 ingredient spending
- Difference: €25,000 reduced annual profit
How often should you check?
Monitor your food cost percentage monthly at minimum. Fluctuations exceeding 3 percentage points warrant immediate investigation.
Many establishments use tools like a food cost calculator to automate this tracking, eliminating manual receipt and invoice calculations.
How do you calculate your food cost percentage?
Gather your sales figures
Get your total sales from your POS system or accounting. Note: this is usually including VAT. For restaurants that's 9% VAT on food.
Convert your sales to excluding VAT
Divide your sales by 1.09 to remove the VAT. For example: €50,000 / 1.09 = €45,872 excl. VAT. Use this amount for further calculations.
Add up all your ingredient costs
Get all your supplier invoices and add up all ingredients. Only include what goes directly into your dishes, not beverages or cleaning supplies.
Calculate the percentage
Divide your total ingredient costs by your sales excl. VAT and multiply by 100. For example: €14,500 / €45,872 × 100 = 31.6%.
Compare with the benchmark
Check if your percentage is between 28% and 35%. Higher? Then investigate where you're losing money. Lower? Maybe you can improve quality or make portions slightly larger.
✨ Pro tip
Track your food cost percentage every 2 weeks instead of monthly during your first 6 months. This tighter monitoring helps you spot trends faster and adjust before small problems become profit killers.

Frequently asked questions
Should I include beverages in the calculation?
No, calculate food costs separately from beverages. Drinks operate on completely different margins and mixing them creates misleading results. Track beverage costs independently for accurate insights.
What if I have both takeout and dine-in?
Combine both revenue streams in your calculation since both carry 9% VAT rates. Add all sales together for your total revenue figure.
What if my percentage is above 35%?
You're likely losing money and need immediate action. Check portion sizes against recipes, verify menu prices reflect current supplier costs, and identify waste sources. Each percentage point above 35% significantly impacts profitability.
Can I calculate this weekly instead of monthly?
Weekly calculations work but interpret carefully. Single weeks can show distorted results from large deliveries or unusually slow periods. Monthly data provides more reliable trends for decision-making.
