Restaurant margins can make or break your business — but 73% of owners track the wrong numbers. Gross margin tells you exactly how many euros you pocket after ingredient costs, not just percentages. It's the clearest picture of which dishes actually put money in your bank account.
What exactly is gross margin?
Gross margin is the cash left over after you subtract ingredient costs from your selling price. These are the actual euros covering your staff wages, rent, utilities, and everything else that keeps your doors open.
💡 Example:
You sell a steak for €32.00 incl. VAT (€29.36 excl. VAT)
- Ingredient costs: €9.50
- Selling price excl. VAT: €29.36
Gross margin: €29.36 - €9.50 = €19.86
The formula for gross margin
The math couldn't be simpler:
Gross margin = Selling price excl. VAT - Ingredient costs
Always work with prices excluding VAT. That 9% food VAT on your menu price goes straight to the tax office, not your pocket.
⚠️ Watch out:
Too many restaurant owners calculate with VAT-inclusive prices. This inflates your margins on paper while your real profitability stays hidden.
Gross margin vs. food cost percentage
Both numbers matter, but they answer different questions:
- Food cost %: Shows efficiency — how much of each euro goes to ingredients
- Gross margin €: Shows profit power — actual cash per dish
💡 Comparison example:
Two dishes with identical 30% food costs:
- Pasta €16.50 excl. VAT → Gross margin: €11.55
- Steak €33.00 excl. VAT → Gross margin: €23.10
Same efficiency, but the steak delivers double the cash per plate.
Why gross margin matters for decisions
Gross margin drives your most important choices:
- Menu design: Which dishes deserve prime real estate?
- Special offers: What can you discount without bleeding money?
- Staffing costs: How many plates to break even each shift?
Something most kitchen managers discover too late: focusing only on food cost percentages can lead you to push low-margin dishes that look efficient but don't pay the bills.
💡 Practical example:
Your chef costs €200 per evening shift. You need enough gross margin to cover this:
- Pasta (€11.55 gross margin): 18 portions needed
- Steak (€23.10 gross margin): 9 portions needed
Higher-margin dishes give you breathing room on slower nights.
Gross margin benchmarks by category
Different dish types typically generate different margins:
- Meat/fish mains: €15-25 per portion
- Pasta dishes: €8-15 per portion
- Salads: €6-12 per portion
- Desserts: €4-8 per portion
These ranges depend heavily on your market positioning and supplier relationships.
Boosting your gross margin
You've got three levers to pull:
- Price increases: Every euro added goes straight to margin
- Cost reduction: Smarter purchasing or waste elimination
- Portion optimization: Right-sizing without disappointing guests
⚠️ Watch out:
Price hikes without research can backfire. Check your competitors' margins and guest price sensitivity before making moves.
How to calculate gross margin? (step by step)
Determine your selling price excluding VAT
Take the price from your menu and divide by 1.09 (for 9% VAT). For example: €32.00 divided by 1.09 = €29.36 excluding VAT.
Calculate your total ingredient costs
Add up all costs: main ingredient, garnish, sauces, oil, butter, everything that goes on the plate. Don't forget anything, not even the parsley as decoration.
Subtract ingredient costs from selling price
Selling price excl. VAT minus ingredient costs = gross margin. In our example: €29.36 - €9.50 = €19.86 gross margin per portion.

Frequently asked questions
Should I include VAT in my gross margin calculation?
No, always calculate with prices excluding VAT. VAT is money you pass on to the tax authorities, not your revenue. For restaurants that's 9% VAT on food.
What is a good gross margin for a restaurant?
That depends on your type of establishment and price level. Main courses often have €15-25 gross margin, side dishes €6-12. More important is that you make enough margin to cover all your costs.
What if my gross margin is too low?
You have three options: increase selling price, lower ingredient costs, or optimize portions. Start with your top-selling dishes — that's where you have the most impact.
Is gross margin the same as profit?
No, gross margin is what remains after ingredients. From this you still need to pay staff, rent, energy and other costs. Only then do you have profit.
Should I include trimming loss in my gross margin?
Yes, trimming loss increases your actual ingredient costs. If you pay €20/kg for whole fish but throw away 40%, your fillet actually costs €33/kg. Calculate with that €33.
How often should I recalculate gross margins?
Check your margins monthly for regular items, immediately when supplier prices change. Seasonal ingredients need weekly reviews since their costs fluctuate constantly.
