Most restaurant owners work with menu prices that include VAT, but margin calculations require VAT-exclusive figures. Learn the step-by-step process to calculate accurate margins without mixing up your numbers.
Most restaurant owners work with menu prices that include VAT since that's what customers see. But your actual margin calculations must use VAT-exclusive figures. Mix these up and your margins will appear inflated by roughly 8%.
Why thinking in prices including VAT causes problems
Your menu shows prices with 9% VAT included. However, margin calculations work off the VAT-exclusive price. Confuse these two and your margins look healthier than reality.
⚠️ Watch out:
Calculate margin using VAT-inclusive prices and you'll overestimate by about 8%. Think you've got 30% margin? It's actually closer to 33%.
Converting from VAT-inclusive to VAT-exclusive
Dutch restaurants pay 9% VAT on food items. Converting from inclusive to exclusive means dividing by 1.09.
💡 Example:
Pasta carbonara menu price: €21.80 (with 9% VAT)
- VAT-exclusive price: €21.80 ÷ 1.09 = €20.00
- Food costs: €6.00
Margin: €20.00 - €6.00 = €14.00 (70% of €20.00)
The proper margin calculation method
Express margins two ways: absolute euros and percentage. Both matter, but percentages make dish comparisons simpler.
Euro margin:
Selling price minus VAT - Food costs = Euro margin
Percentage margin:
(Euro margin ÷ VAT-exclusive selling price) × 100 = Margin percentage
💡 Example comparison:
Steak menu price: €32.70 including VAT
- Minus VAT: €32.70 ÷ 1.09 = €30.00
- Food costs: €9.00
- Margin: €30.00 - €9.00 = €21.00
- Margin percentage: (€21.00 ÷ €30.00) × 100 = 70%
Using €32.70 instead: (€23.70 ÷ €32.70) × 100 = 72% → Incorrect calculation!
Common calculation errors to avoid
The most frequent mistake involves mixing VAT rates. After managing kitchen operations for nearly a decade, I've seen this trip up countless operators. Pay attention to these scenarios:
- Restaurant food: 9% VAT
- Alcoholic drinks: 21% VAT
- Takeaway orders: 9% VAT
💡 Wine example:
Wine bottle menu price: €24.20 (with 21% VAT)
- Minus VAT: €24.20 ÷ 1.21 = €20.00
- Wholesale cost: €8.00
- Margin: €20.00 - €8.00 = €12.00 (60%)
Remember: wine uses 1.21, not 1.09!
Daily workflow recommendations
Simplify your routine with these habits:
- Store VAT-exclusive prices in your POS system too
- Run all margin calculations VAT-free
- Monitor supplier price changes monthly
- Consider tools like a food cost calculator for automatic calculations
⚠️ Watch out:
Supplier price increases eat into margins unless you adjust menu prices accordingly. You might not notice the erosion until it's substantial.
How do you calculate margin correctly? (step by step)
Determine the selling price excluding VAT
Take the price from your menu and divide by 1.09 (at 9% VAT) or by 1.21 (at 21% VAT for alcohol). This is your actual selling price without VAT.
Add up all purchase costs
Calculate all ingredient costs together: main ingredient, garnish, sauces, oil, butter. Don't forget anything that goes on the plate.
Calculate your margin
Subtract the purchase costs from the selling price excluding VAT. This is your margin in euros. For percentage: divide the margin by the selling price and multiply by 100.
✨ Pro tip
Check your top 5 dishes every 2 weeks by dividing menu prices by 1.09 (or 1.21 for alcohol). This quick calculation reveals your true selling price and keeps margin awareness sharp.

Frequently asked questions
Why can't I just calculate using the price on my menu?
Menu prices include VAT that goes to tax authorities, not your revenue. Your true selling price excludes VAT, so margins must reflect this reality. Otherwise you're calculating against money that isn't actually yours.
What if I sell both food and drinks?
Food carries 9% VAT while alcoholic beverages get hit with 21%. Apply the right rate for each category: divide by 1.09 for food items, by 1.21 for alcohol.
How do I handle mixed dishes with different VAT rates?
Break down the components by their VAT categories. If a dish includes both food and alcohol, calculate each portion separately with its applicable rate. This ensures precision in your margin analysis.
