Digital menu cards via QR codes don't change your margin calculation. The margin stays the same, but you do get new opportunities to adjust prices dynamically. Many entrepreneurs think a QR menu automatically generates more profit, but it still comes down to the basics: cost price versus selling price.
Margin calculation stays the same
Whether your menu is on paper or on a screen, the margin calculation doesn't change. You still have the same ingredients, the same cost price, and the same selling price.
💡 Example:
Your pasta carbonara on paper menu:
- Ingredient costs: €6.80
- Selling price: €18.50 incl. VAT (€16.97 excl.)
- Margin: €16.97 - €6.80 = €10.17
- Margin %: (€10.17 / €16.97) × 100 = 59.9%
The same pasta on a QR menu has exactly the same margin.
Benefits of digital price adjustments
The big difference is in flexibility. With a QR menu card, you can adjust prices without printing new cards. This opens up new possibilities:
- Dynamic pricing: More expensive during peak hours, cheaper during quiet times
- Quick adjustments: Supplier raises prices? Adjust immediately
- A/B testing: Test different prices and see what works
- Seasonal menus: Different prices for summer/winter menu
⚠️ Watch out:
Guests will notice if you constantly adjust prices. Don't do this more than 1-2 times per month, or you'll lose their trust.
Optimizing margin with digital data
QR menu cards often give you extra data about what guests order. You can use this information to optimize your margin:
- Popularity per dish: Which dishes are ordered most?
- Time-based patterns: What do guests order at lunch vs. dinner?
- Combinations: Which dishes are ordered together?
💡 Example data analysis:
You notice that your steak (65% margin) is mainly ordered after 19:00, while your pasta (45% margin) is popular at lunch.
- Strategy: Promote steak more during dinner
- Lunch: Focus on volume with pasta
- Result: Higher average margin per time slot
Cost price calculation for QR menu
The basics remain the same as any other menu. For each dish you calculate:
- Ingredient costs: All ingredients per portion
- Selling price excl. VAT: Price on QR menu / 1.09
- Margin in euros: Selling price excl. VAT - ingredient costs
- Margin percentage: (Margin / selling price excl. VAT) × 100
💡 Formula:
Margin % = ((Selling price excl. VAT - Ingredient costs) / Selling price excl. VAT) × 100
Or shorter: Margin % = (1 - (Ingredient costs / Selling price excl. VAT)) × 100
Practical tips for QR menu margin
With a digital menu, you can steer more intelligently toward profitability:
- Highlight profitable dishes: Put dishes with high margin at the top
- Visual attention: Use photos for dishes with good margin
- Bundling: Combine low-margin dishes with high-margin side dishes
- Menu engineering: Remove dishes with low margin AND low popularity
⚠️ Watch out:
A QR menu is a tool, not a magic wand. Your margin only improves if you use the data to make better decisions about prices and menu composition.
How do you calculate margin on a QR menu? (step by step)
Calculate cost price per dish
Add up all ingredient costs per portion. Don't forget garnishes, sauces, oil, or butter. This is your cost price per dish, regardless of whether it's on paper or digital.
Determine selling price excl. VAT
Take the price from your QR menu and divide by 1.09 for food (9% VAT). At €20.00 incl. VAT this becomes €18.35 excl. VAT. This is your actual selling price for the calculation.
Calculate margin in euros and percentage
Subtract cost price from selling price excl. VAT for margin in euros. Then divide by selling price excl. VAT and multiply by 100 for your margin percentage. Aim for at least 60% margin.
✨ Pro tip
Check which dishes are viewed most but not ordered via your QR menu analytics. These often have a price that's too high for the perceived value - perfect candidates for price adjustment.

Frequently asked questions
Does a QR menu have a different margin than a paper menu?
No, the margin calculation is identical. You have the same ingredients and the same prices. The advantage is in the flexibility to adjust prices more quickly.
Can I charge higher prices with a QR menu?
Not automatically. Guests still compare prices with other restaurants. You can use dynamic pricing though: slightly more expensive during peak hours, but this needs to be subtle.
How often can I adjust prices on a QR menu?
Maximum 1-2 times per month for regular dishes. Guests need to be able to trust your prices. Seasonal menus can change prices more frequently.
Do I need to calculate VAT differently for digital menus?
No, VAT remains 9% for food in restaurants and 21% for alcoholic beverages. This doesn't change based on the medium your menu is on.
Does a QR menu automatically generate more profit?
Only if you use the extra opportunities: better data analysis, menu optimization, and smart price adjustments. The menu itself doesn't increase your margin.
