Most restaurants guess at their menu prices, while smart operators calculate them precisely. The cost-plus method gives you the exact minimum price needed to stay profitable by adding your desired margin to actual ingredient costs. Without this calculation, you're likely losing money on dishes that seem popular.
What is the cost-plus method?
Cost-plus pricing follows a straightforward formula: ingredient costs + profit margin = selling price. You determine the complete cost of making a dish, then add your target percentage for profit. This establishes the absolute minimum price needed to keep your restaurant profitable.
💡 Example:
Pasta carbonara - ingredient costs:
- Pasta: €0.85
- Pancetta: €2.40
- Eggs: €0.75
- Parmesan: €1.60
- Other (oil, pepper, etc.): €0.40
Total ingredient costs: €6.00
The cost-plus pricing formula
Minimum selling price excl. VAT = Ingredient costs ÷ (Target food cost % ÷ 100)
For your final menu price, multiply by 1.09 to include the 9% VAT on restaurant meals.
💡 Example calculation:
Ingredient costs: €6.00
Target food cost: 28%
Step 1: €6.00 ÷ 0.28 = €21.43 excl. VAT
Step 2: €21.43 × 1.09 = €23.36 incl. VAT
Final menu price: €23.40 (rounded)
Choosing your food cost percentage
Your food cost percentage directly impacts profit margins. Different restaurant types typically use these ranges:
- Fine dining: 28-32% (premium service justifies higher margins)
- Casual dining: 30-35% (balancing quality with accessibility)
- Fast casual: 25-30% (volume and efficiency drive profits)
- Delivery-focused: 32-38% (platform fees eat into margins)
⚠️ Note:
Lower food costs don't guarantee higher profits. You've still got labor, rent, and utilities to cover while staying competitive in your market.
Adapting for different scenarios
Lunch versus dinner: Lunch menus often run 25-30% food cost since customers expect lower prices and faster service.
Seasonal ingredients: Recalculate whenever ingredient prices shift dramatically. Asparagus might cost €8/kg in season but €24/kg off-season.
One of the most common blind spots in kitchen management is failing to adjust prices for seasonal fluctuations, which can destroy profit margins overnight.
Promotional items: You can temporarily accept higher food costs to draw customers, but ensure your regular menu items compensate.
💡 Example seasonal adjustment:
Asparagus dish pricing by season:
- May: €8/kg asparagus → total ingredients €12.00 → menu price €26.50
- January: €24/kg asparagus → total ingredients €28.00 → menu price €61.50
Smart move: Only feature asparagus during peak season
Balancing cost-plus with market reality
Your calculated price sets the floor, not the ceiling. But you also need to consider:
- Competitor pricing for similar dishes
- Customer price expectations in your segment
- Your dish's unique value proposition (justifying premium pricing)
If your cost-plus calculation exceeds market rates, you have three choices: substitute cheaper ingredients, reduce portion sizes, or remove the dish entirely. Digital calculators can help you quickly test different scenarios and find the sweet spot.
How do you calculate the ideal selling price? (step by step)
Calculate the full ingredient costs
Add up all ingredients: main product, garnish, sauces, oil, butter, decoration. Don't forget anything that goes on the plate. Calculate using current purchase prices from your supplier.
Choose your desired food cost percentage
Determine what percentage of your selling price can go to ingredients. For most restaurants this is between 28-35%. The lower the percentage, the more room for other costs and profit.
Calculate your minimum selling price
Divide your ingredient costs by your food cost percentage. Multiply by 1.09 for VAT. This is your minimum menu price to stay profitable.

Frequently asked questions
Should I include VAT in my cost-plus calculation?
Always calculate excluding VAT first, then add the 9% for your final menu price. Including VAT in your initial calculation makes your food cost percentage appear artificially low, which can lead to pricing mistakes.
Can I use different food cost percentages for different dishes?
Absolutely, and you should. Signature dishes can run 35-40% food cost since they draw customers in. Balance these with your high-volume basics at 25-30% food cost to maintain overall profitability.
What if my cost-plus price exceeds what competitors charge?
You have three options: switch to less expensive ingredients, reduce portion sizes, or drop the dish from your menu. Selling below your calculated minimum is a guaranteed path to losses.
