Over 73% of restaurants report higher ingredient costs for specialty diet dishes, yet many still use standard margin calculations. Keto and vegan ingredients cost 30-50% more than regular products, but customers pay premium prices for these options. Delivery adds another layer with platform fees and specialized packaging that standard costing methods miss.
Why special diets have different margins
Keto and vegan dishes demand pricier ingredients. Coconut milk runs €8 per liter versus €1.50 for regular milk. Cashews for vegan cheese hit €25 per kilo. And organic vegetables for keto? They're 40-60% more expensive than conventional produce.
💡 Example keto pasta:
Regular pasta carbonara vs. keto courgetti carbonara:
- Pasta: €0.30 → Courgetti: €1.20
- Cream: €0.80 → Coconut cream: €2.40
- Bacon: €1.50 → Organic bacon: €2.80
- Cheese: €1.20 → Cashew cheese: €3.50
Cost price jumps from €3.80 to €9.90
Including platform fees and packaging costs
Delivery platforms take their cut - 15-30% of your selling price including VAT. That €20 dish? You're handing over €3-6 to Deliveroo or Uber Eats.
Packaging costs for special diets hit harder:
- Separate containers for allergy-friendly dishes
- Extra labels and diet-specific stickers
- Double packaging for cross-contamination prevention
- Biodegradable containers cost 20-40% more
⚠️ Note:
Platform fees hit your selling price including VAT. That €25 dish costs you €5 in platform fees at 20%. Build this into your cost structure from day one.

Based on real restaurant P&L data, delivery margins for specialty diets include these cost components:

- Ingredients: €8.50
- Packaging: €1.20
- Platform fee (20%): €4.50

Pricing strategy for special diets
Customers following special diets pay premium prices for quality and convenience. You can charge 20-40% above regular dish prices. But you've got to manage your food costs ruthlessly.
Specialty diet delivery guidelines:
- Food cost: cap at 35% (higher than dine-in due to platform fees)
- Platform fees: 15-30%
- Packaging: 3-8%
- Net margin target: 25-45%
💡 Example keto salad:
Target: €7.50 net margin on keto salad:
- Ingredients: €6.80
- Packaging: €0.90
- Desired margin: €7.50
- Subtotal: €15.20
- Platform fee 20%: €3.80
- Price excl. VAT: €19.00
Final menu price: €20.71 incl. VAT
Control and optimization
Review your specialty diet margins weekly. Organic and specialty ingredient prices swing more wildly than standard products. Adjust your menu prices whenever suppliers bump their rates.
Track your conversion rates too. How many customers actually order special diets versus regular options? Low demand might mean fewer varieties with higher margins work better than extensive menus with thin profits.
How do you calculate the margin on delivery menus for special diets?
Calculate all ingredient costs including premium products
Add up all costs: vegan alternatives, organic products, specialty ingredients. Keto and vegan are often 30-50% more expensive than standard ingredients. Don't forget herbs, oils and garnishes.
Add packaging and label costs
Special diets often have more expensive packaging: allergy-friendly containers, extra labels, separate packaging. Calculate €0.50-1.50 per portion versus €0.30 for standard packaging.
Factor platform fee into your cost price
Platform fees are 15-30% of your selling price including VAT. This is a direct cost item that reduces your margin. Factor this in as a cost item, not as a percentage of your profit.
Calculate your minimum selling price
Divide your total costs by your desired margin percentage. For delivery of special diets, 30-35% food cost is realistic. Add platform fee and packaging and calculate back to menu price including VAT.
