Your average margin for the whole day is like checking your wallet after a night out – you know you spent money, but do you know what you actually have left? Many restaurant owners track their revenue religiously but remain clueless about their actual profit. Here's how to calculate this crucial metric step-by-step.
What is average margin?
Your average margin represents the percentage of revenue that stays in your pocket after covering all direct costs. Unlike food cost calculations that focus on spending, margin reveals what you actually keep.
💡 Example:
You sell a steak for €32.00 (incl. 9% VAT):
- Selling price excl. VAT: €29.36
- Ingredient costs: €9.50
- Margin: €29.36 - €9.50 = €19.86
Margin percentage: (€19.86 / €29.36) × 100 = 67.6%
The formula for average margin
For individual dishes:
Margin % = ((Selling price excl. VAT - Ingredient costs) / Selling price excl. VAT) × 100
For your entire day's operation:
Average margin % = (Total revenue excl. VAT - Total ingredient costs) / Total revenue excl. VAT × 100
⚠️ Note:
Always work with VAT-exclusive prices. Menu prices include 9% VAT for food items.
Data you need
Calculating your average margin requires these specific data points:
- Revenue per dish: Sales volume for each menu item
- Selling prices excl. VAT: Menu price divided by 1.09
- Ingredient costs per dish: Complete ingredient expenses
- Number of portions sold: Exact quantities for each dish
💡 Example daily calculation:
Daily sales breakdown:
- 50× steak at €29.36 excl. VAT (ingredients €9.50)
- 30× pasta at €16.51 excl. VAT (ingredients €4.80)
- 20× salad at €12.84 excl. VAT (ingredients €3.20)
Total revenue: (50×€29.36) + (30×€16.51) + (20×€12.84) = €1,979.50
Total ingredient costs: (50×€9.50) + (30×€4.80) + (20×€3.20) = €683.00
Average margin: ((€1,979.50 - €683.00) / €1,979.50) × 100 = 65.5%
Difference between margin and food cost
Many restaurant operators mix up margin with food cost. But they're completely different metrics:
- Food cost: Percentage of selling price spent on ingredients
- Margin: Percentage of selling price you retain
A 30% food cost equals a 70% margin. A 35% food cost means a 65% margin.
💡 Example:
Pasta carbonara €18.50 incl. VAT:
- Selling price excl. VAT: €16.97
- Ingredient costs: €5.10
- Food cost: (€5.10 / €16.97) × 100 = 30.1%
- Margin: ((€16.97 - €5.10) / €16.97) × 100 = 69.9%
Why average margin is important
Your average margin reveals more than food cost percentages ever could:
- Profitability: What's available for fixed costs and actual profit?
- Pricing strategy: Are your menu prices adequate?
- Menu performance: Are profitable dishes selling well?
- Financial trends: Is your margin improving or declining?
Restaurant margins typically range from 65% to 72%. Anything below 65% signals either excessive ingredient costs or inadequate pricing – the kind of thing you only learn after closing your first month at a loss.
⚠️ Note:
Margin isn't profit. You still need to cover labor costs, rent, utilities, equipment depreciation and other operational expenses.
How often to calculate?
Track your average margin consistently:
- Daily: For immediate monitoring and quick adjustments
- Weekly: For identifying trends and making comparisons
- Monthly: For comprehensive reporting and strategic decisions
Food cost management systems automate this process entirely. You input sales data and receive instant margin calculations across daily, weekly or monthly periods without manual computation.
How do you calculate average margin? (step by step)
Collect sales figures for the day
Note for each dish: how much sold, selling price incl. VAT, and ingredient costs per portion. You need this data to calculate total revenue and costs.
Calculate total revenue excluding VAT
Multiply number of portions sold by selling price excl. VAT per dish. Add all dishes together for your total revenue excl. VAT.
Calculate total ingredient costs
Multiply number of portions sold by ingredient costs per dish. Add all dishes together for your total ingredient costs for that day.
Apply the margin formula
Subtract ingredient costs from revenue, divide by revenue and multiply by 100. Formula: ((Revenue - Costs) / Revenue) × 100 = Average margin %.
✨ Pro tip
Calculate margins separately for your top 7 dishes over the past 14 days. These volume leaders typically represent 70% of your total margin impact.

Frequently asked questions
What is a good average margin for a restaurant?
Restaurant margins typically range from 65% to 72%. This translates to ingredient costs consuming 28% to 35% of your revenue.
Should I include VAT in my margin calculation?
Never include VAT in margin calculations. Always use VAT-exclusive prices by dividing your menu price by 1.09 for the 9% food VAT rate.
What if my average margin drops below 65%?
This indicates either excessive ingredient costs or insufficient menu pricing. Analyze your top-selling items first and adjust prices or source more cost-effective ingredients.
How do seasonal ingredients affect my average margin?
Seasonal price fluctuations can significantly impact margins. Track ingredient costs weekly and adjust menu prices quarterly to maintain consistent profitability.
Is margin the same as profit?
Absolutely not. Margin represents what remains after ingredient costs, but you still must cover labor, rent, utilities and other operational expenses before reaching actual profit.
What if different dishes have wildly different margins?
This is completely normal and expected. Focus on optimizing margins for your highest-volume sellers since they drive your overall average margin performance.
