Margin per dish determines whether you make a profit or loss. Many restaurant owners only look at revenue, but forget that a full restaurant can still...
A pasta carbonara selling for €18.50 might seem profitable until you realize you're only keeping €2.30 after all costs. Most restaurant owners focus on revenue numbers but miss that packed dining rooms can still drain profits when margins run too thin. Calculating your real margin per dish reveals which menu items actually make money.
Margin represents the money remaining after subtracting ingredient costs from your selling price. It's what you actually keep from each dish sold.
You'll work with two margin types:
- Gross margin in euros: Selling price minus ingredient costs
- Margin percentage: What percentage of your selling price you retain
💡 Example:
Pasta carbonara sells for €18.50 incl. VAT:
Selling price excl. VAT: €16.97
Ingredient costs: €5.10
Gross margin: €16.97 - €5.10 = €11.87
Margin percentage: €11.87 / €16.97 = 69.9%
Essential formulas for margin calculations
Use these formulas for accurate margin calculations:
Gross margin in euros:
Selling price excl. VAT - Ingredient costs = Gross margin
Margin percentage:
(Gross margin / Selling price excl. VAT) × 100 = Margin %
Direct calculation:
((Selling price excl. VAT - Ingredient costs) / Selling price excl. VAT) × 100
⚠️ Critical point:
Always work with prices EXCLUDING VAT. Menu prices include 9% VAT that goes to tax authorities, not your pocket. Convert €18.50 incl. VAT to €16.97 excl. VAT for calculations.
Count every ingredient that touches the plate
Missing ingredients in your calculations creates false profit expectations. Include everything:
- Primary ingredients (meat, fish, pasta)
- Garnishes and vegetables
- Sauces and dressings
- Cooking oils and butter
- Herbs and seasonings
- Bread or accompaniments
- Plate garnishes
💡 Steak example:
Steak menu €32.00 incl. VAT (€29.36 excl. VAT):
Steak 200g: €6.40
Fries 150g: €0.45
Salad garnish: €0.30
Pepper sauce: €0.85
Cooking butter: €0.15
Herbs: €0.05
Total ingredient costs: €8.20
Gross margin: €29.36 - €8.20 = €21.16 (72.1%)
Target margins for different restaurant types
Standard restaurant margins range from 65% to 72%, meaning food costs should stay between 28% and 35%.
Margin benchmarks by establishment:
- Fine dining: 65-72% margin (28-35% food cost)
- Casual dining: 65-72% margin (28-35% food cost)
- Bistro: 68-75% margin (25-32% food cost)
- Pizzeria: 72-80% margin (20-28% food cost)
⚠️ Reality check:
High margins don't guarantee profits. You've still got staff wages, rent, utilities, and other expenses to cover. Your margin needs enough cushion for all operating costs.
Analyze margins across your menu
Calculate margins for your top-selling dishes to identify your real money-makers.
💡 Comparison example:
Three dishes priced at €25.00 incl. VAT (€22.94 excl. VAT):
Fish: €8.50 ingredients → €14.44 margin (63%)
Chicken: €6.20 ingredients → €16.74 margin (73%)
Vegetarian: €4.80 ingredients → €18.14 margin (79%)
The vegetarian option generates €3.70 more profit per serving than the fish dish.
Price adjustment triggers
Monitor your margins regularly since supplier prices shift constantly. Most restaurants lag behind price increases, quietly eroding profits.
Adjust prices when:
- Margins drop below 65%
- Supplier costs increase over 5%
- Actual profits fall short of projections
- Market competitors raise their prices
Real-world case: Restaurant De Bosuil
Owner Jan analyzes his five main courses to identify profit drivers:
Salmon fillet (€28.50 incl. VAT = €26.15 excl. VAT):
- Salmon 180g: €7.20
- Risotto: €1.80
- Vegetables: €1.40
- Sauce and herbs: €0.60
- Total: €11.00 → Margin: €15.15 (58%)
Entrecote (€31.00 incl. VAT = €28.44 excl. VAT):
- Entrecote 220g: €8.80
- Fried potatoes: €0.90
- Vegetables and sauce: €1.30
- Total: €11.00 → Margin: €17.44 (61%)
Chicken satay (€22.50 incl. VAT = €20.64 excl. VAT):
- Chicken fillet 200g: €4.20
- Satay sauce: €1.10
- Fries and salad: €1.40
- Total: €6.70 → Margin: €13.94 (68%)
Jan discovers his premium dishes deliver the weakest margins. He switches to seasonal fish with better cost structure or raises the salmon price to €31.00.
Seasonal fluctuations and smart purchasing
Margins swing dramatically with seasonal price changes. Vegetables cost less in peak season, fish prices vary with catch cycles, and meat markets fluctuate constantly.
Margin optimization strategies:
- Rotate menu items seasonally
- Source vegetables during peak seasons
- Negotiate bulk order discounts
- Compare multiple supplier quotes
- Track wholesaler promotional offers
Margin calculation mistakes that cost money
1. Including VAT in calculations
This error inflates your margin by 9%. A dish priced at €21.80 incl. VAT actually sells for €20.00 excl. VAT - that's your real revenue base.
2. Overlooking small ingredients
Oil, butter, herbs, and garnishes add €1-2 per dish. That oversight - a mistake that costs the average restaurant EUR 200-400 per month - destroys margin accuracy across your entire menu.
3. Using incorrect portion weights
Kitchen staff often serve larger portions than calculated. If you price based on 200g meat but serve 250g, your margins crumble quickly.
4. Working with outdated prices
Supplier costs change regularly, but many operators use months-old pricing data. Review your ingredient costs quarterly minimum.
5. Ignoring accompaniments
Sauces, sides, and garnishes carry real costs. That €6 steak becomes €8.50 with all additions factored in.
Your margin calculation roadmap
Accurate margins demand precision and thoroughness. Calculate excluding VAT, account for every ingredient, and verify your numbers regularly. Target 65-75% margins while ensuring adequate coverage for all operating expenses. Compare dish-by-dish performance to identify your most profitable offerings and optimize your menu accordingly.
How do you calculate margin per dish? (step by step)
Calculate selling price excluding VAT
Divide your menu price by 1.09 to get the price excl. VAT. For €28.00 incl. VAT: €28.00 ÷ 1.09 = €25.69 excl. VAT.
Add up all ingredient costs
Calculate what each ingredient costs per portion. Don't forget anything: main ingredients, garnish, sauces, oil, herbs and decoration. Add everything together.
Calculate gross margin and percentage
Subtract ingredient costs from selling price excl. VAT to get your gross margin in euros. Then divide the gross margin by the selling price excl. VAT and multiply by 100 for the percentage.
✨ Pro tip
Track your 3 highest-volume dishes weekly for margin changes. These items drive 60-70% of your food revenue, so catching cost creep early protects your bottom line.

Frequently asked questions
Should I include VAT in my margin calculation?
Never calculate with VAT included. VAT goes directly to tax authorities, not your revenue stream. Divide menu prices by 1.09 to get your actual selling price excluding VAT.
What if my margin drops below 65%?
You're likely underpricing that dish or missing ingredient costs in your calculations. Review all components and consider raising your selling price. Margins under 65% rarely leave enough room for operating expenses.
How often should I check my margins?
Review margins monthly for your best-selling dishes, quarterly for your full menu. Supplier prices shift constantly - last month's profitable dish might be losing money today.
Why does my calculated margin feel wrong compared to actual profits?
You're probably missing ingredients or calculating with VAT-inclusive prices. Many operators forget oils, herbs, and garnishes, which underestimates true food costs by 15-20%.
