Most restaurants think aggressive pricing means guessing a 'low' number and hoping for the best. But there's a precise break-even point below which you're literally paying guests to eat your food. Calculating your minimum selling price lets you choose exactly how aggressive to get.
The minimum selling price formula
Your minimum selling price covers every direct cost of that dish. Beyond that point, you decide how much margin to add - or skip entirely.
💡 Formula:
Minimum price = Ingredient costs / (1 - Other costs %)
Where other costs = labor + energy + depreciation + overhead
What counts as ingredient costs?
Everything that touches the plate gets counted:
- Primary protein or main component
- Every side dish and garnish
- Sauces, dressings, and condiments
- Cooking oils, butter, seasoning blends
- Bread, garnish, anything the customer receives
⚠️ Watch out:
Factor in prep waste! Whole fish at €18/kg with 45% waste means you're paying €32.73/kg for usable fillet.
Estimating other costs
From tracking this across dozens of restaurants, these percentages of total revenue work reliably:
- Labor cost: 25-35% of revenue
- Energy: 3-6% of revenue
- Depreciation + overhead: 8-12% of revenue
- Total other costs: 36-53% of revenue
Use 45% for conservative calculations. Better to underestimate profit than overestimate it.
💡 Example special:
Spring asparagus special breakdown:
- Fresh asparagus (300g): €4.20
- House hollandaise: €1.80
- Prosciutto (80g): €2.40
- Baby potatoes: €0.90
Total ingredient costs: €9.30
Minimum price: €9.30 / (1 - 0.45) = €16.91 excl. VAT
Menu price minimum: €16.91 × 1.09 = €18.43
Choosing your margin strategy
Now you know where break-even sits. Above that, you control exactly how much profit to take:
- 0-5% profit: True loss-leader pricing to drive traffic
- 5-10% profit: Aggressive but sustainable
- 10-15% profit: Standard special margins
💡 Pricing scenarios:
Starting from minimum price of €18.43:
- Break-even: €18.50
- With 5% profit: €19.50
- With 10% profit: €20.50
Your call: attract maximum guests at €18.50 or capture more profit at €20.50?
Why precise calculations matter
Knowing your minimum lets you make informed trade-offs. You'll know exactly how much profit you're sacrificing for customer acquisition.
Too many restaurants throw out numbers like "€19.50 sounds reasonable" without understanding whether they're making or losing money on each plate.
⚠️ Seasonal ingredient warning:
Market prices shift weekly for seasonal items. Verify your purchase costs before launching specials, or watch your margins evaporate overnight.
How do you calculate the minimum selling price? (step by step)
Calculate exact ingredient costs
Add up all ingredients that go on the plate. Don't forget anything: main ingredient, side dishes, sauces, oil for cooking, spices, decoration. Include cutting loss if you process whole products.
Determine your other costs percentage
Estimate your total other costs (labor + energy + overhead) as a percentage of revenue. For most restaurants, 45% is a safe estimate. When in doubt, calculate conservatively at 50%.
Calculate minimum price and choose your margin
Divide ingredient costs by (1 - other costs %). This is your break-even price excl. VAT. Multiply by 1.09 for the menu price. Now decide how much profit you want on top for your special.
✨ Pro tip
Track your asparagus supplier's prices twice weekly during peak season - I've seen costs jump 40% in just 10 days, turning a profitable special into a money pit overnight.

Frequently asked questions
Can I just maintain 30% food cost for my special?
Only if your other costs actually run 70% of revenue. For traffic-driving specials, you can deliberately accept higher food cost percentages - just stay above your break-even point.
What if seasonal ingredients spike in price mid-special?
Monitor purchase prices weekly for seasonal items. If asparagus jumps from €14 to €18 per kilo, that's €1.20 more per portion. Either adjust your menu price or pause the special until costs stabilize.
Should packaging costs be included for takeaway specials?
Absolutely - factor in containers, bags, and utensils as ingredient costs. Budget €0.50-1.50 extra per portion for quality takeaway packaging.
Can a special intentionally run at a loss?
Yes, as a customer acquisition investment. But calculate exactly how much you're 'paying' per guest - if they order drinks and desserts too, the total transaction can still be profitable.
