Why do so many restaurant owners think they're profitable when they're actually losing money on every plate? Most entrepreneurs forget crucial cost items like energy and packaging. Here's how to calculate your real dish margin including all hidden costs.
What is a complete margin calculation?
A complete margin calculation goes beyond just ingredient costs. You include all direct costs needed to make and serve that dish.
- Ingredient costs: all products that go on the plate
- Energy costs: gas, electricity for preparation
- Packaging costs: plates, containers, cutlery, napkins
- Other direct costs: oil, salt, spices
⚠️ Heads up:
Many restaurants only calculate with ingredient costs and end up 3-5 percentage points too low on their actual food cost.
Calculate energy costs per dish
Energy costs are tricky to assign per dish, but you can make a reasonable estimate:
- Standard hospitality energy costs: 4-6% of revenue
- Per dish: 2-4% of your selling price
- Energy-intensive dishes: fryer, grill, oven = 4-6%
- Cold dishes: salads, carpaccio = 1-2%
💡 Example energy costs:
Grilled steak for €32.00 (incl. 9% VAT):
- Selling price excl. VAT: €29.36
- Energy costs (5%): €1.47
- For pasta (2%): €0.59
Include packaging costs
Packaging costs get overlooked constantly, but they can hit 1-3% of your selling price:
- Dine-in: plate, cutlery, napkin = €0.15-0.30 per dish
- Takeaway: container, bag, cutlery, napkin = €0.20-0.50 per dish
- Delivery: insulated containers, stickers, bags = €0.30-0.70 per dish
💡 Example packaging costs:
Pasta carbonara delivery €18.50:
- Insulated container: €0.25
- Plastic cutlery: €0.08
- Napkin: €0.02
- Bag + sticker: €0.15
Total packaging: €0.50
The complete margin formula
With all costs included, here's your formula:
Total direct costs = Ingredients + Energy + Packaging + Other
Margin € = Selling price excl. VAT - Total direct costs
Margin % = (Margin € / Selling price excl. VAT) × 100
💡 Complete example:
Steak €32.00 (incl. 9% VAT) = €29.36 excl. VAT:
- Ingredients: €9.50
- Energy (grill, 5%): €1.47
- Packaging (plate, cutlery): €0.25
- Other (oil, salt, spices): €0.30
Total costs: €11.52
Margin: €29.36 - €11.52 = €17.84 (60.8%)
What is a good margin?
After all direct costs, you still have labor, rent, and other fixed costs to cover. From years of working in professional kitchens, these margins work:
- Fine dining: 55-65%
- Casual dining: 60-70%
- Fast casual: 65-75%
- Delivery: 50-60% (higher platform fees)
⚠️ Heads up:
This is your margin before labor and fixed costs. You still need at least 25-35% for staff, rent, and other costs to be profitable.
Digital tracking vs. manual
Doing this calculation for each dish manually takes forever. Many entrepreneurs use a system like KitchenNmbrs to:
- Automatically include all cost items
- Set energy percentages per cooking method
- Add packaging costs per service type
- Immediately see which dishes don't generate enough profit
How do you calculate the complete margin? (step by step)
Gather all ingredient costs
Add up all products that go on the plate: main ingredient, garnish, sauces, oil, butter, spices. Calculate with actual purchase prices including trim loss.
Calculate energy and packaging costs
Estimate energy costs at 2-6% of selling price (depending on cooking method). Add packaging costs: plates, containers, cutlery, napkins. For delivery also bags and stickers.
Calculate the margin
Subtract all direct costs from your selling price excluding VAT. Divide the result by the selling price excl. VAT and multiply by 100 for the percentage.
✨ Pro tip
Calculate the full margin on your 3 highest-volume dishes every 6 weeks. These dishes drive 60% of your profit, so getting their costs right makes or breaks your bottom line.

Frequently asked questions
Do I really need to calculate energy costs per dish?
An exact calculation is difficult, but an estimate of 2-6% of your selling price gives a realistic picture. Cold dishes at the lower end, grilled and fried dishes at the higher end.
What if my packaging costs are higher than 3%?
With premium packaging or many small portions, packaging costs can run up to 5-8%. Calculate this precisely and adjust your selling price, or look for cheaper alternatives.
How often should I update this calculation?
Check your 10 best-selling dishes at least every 3 months. With strong inflation or new suppliers, do it more often. Ingredient prices change regularly.
Is 60% margin after direct costs enough?
That depends on your fixed costs. You still need 25-35% for staff, rent, and other costs. With 60% margin you have 25-35% left for profit and unexpected costs.
