Most restaurant owners think healthy menus automatically mean better profits because customers pay premium prices. Reality check: diet-focused delivery often comes with hidden costs that can slash your margins. Factor in organic ingredients, specialized packaging, and platform fees, and you might be surprised by what's left.
Why diet menus are different
Healthy delivery menus operate on a completely different cost structure than regular dishes. Sure, ingredients cost more, but customers also expect premium quality at every touchpoint.
- Organic ingredients cost 20-40% more
- Superfoods and specialty proteins are pricey
- Smaller portions mean less volume discount
- Special packaging for fresh ingredients
💡 Example:
Quinoa bowl with salmon, selling price €16.50 (incl. 9% VAT):
- Organic quinoa: €1.20
- Salmon fillet (120g): €4.80
- Avocado (half): €1.00
- Vegetable mix: €1.50
- Tahini dressing: €0.60
- Sustainable packaging: €0.80
Total ingredient costs: €9.90
Calculate your actual food cost
Diet menus require you to track every single cost - even the ones that seem insignificant.
Formula: Food cost % = (Ingredients + Packaging + Additions) / Selling price excl. VAT × 100
⚠️ Note:
Don't overlook packaging costs. Eco-friendly containers for healthy meals can run €0.50-€1.50 per portion - a mistake that costs the average restaurant EUR 200-400 per month.
Include platform fees in your calculation
Delivery platforms eat into your margins with commission rates that vary wildly. You can't ignore this when calculating profitability.
- Thuisbezorgd: 13-15% + €0.35 per order
- Uber Eats: 15-30% depending on contract
- Own delivery: staff + fuel
💡 Example calculation:
Quinoa bowl €16.50 via Thuisbezorgd:
- Selling price excl. VAT: €15.14
- Platform fee (15%): €2.27
- Net revenue: €12.87
- Ingredient costs: €9.90
Actual food cost: €9.90 / €12.87 = 77%
Healthy margins for diet menus
Higher ingredient costs and platform fees mean your margins will look different from traditional food service. And that's okay.
- Standard food cost for diet menus: 35-45%
- Platform fee impact: 15-30% of order value
- Net margin after all costs: 15-25%
Those numbers might seem tight, but remember - customers pay premium prices for healthy options. A quinoa bowl at €16.50 would cost €12.00 as pasta.
💡 Full margin calculation example:
Quinoa bowl - complete cost breakdown:
- Order value: €16.50
- Platform fee (15%): €2.48
- VAT (9%): €1.36
- Net revenue: €12.66
- Ingredients + packaging: €9.90
Gross profit: €2.76 (22% of net revenue)
Optimization tips for better margins
Small adjustments can boost your margins without sacrificing the quality your customers expect.
- Bulk purchasing: Buy quinoa, nuts and seeds in large packages
- Seasonal vegetables: Adjust menu to cheap seasonal products
- Own delivery: Cheaper than platforms with sufficient volume
- Minimum order value: €20+ to spread fixed costs
⚠️ Note:
Resist the urge to just raise prices. Health-conscious customers are often price-sensitive too. Focus on smarter purchasing and operational efficiency instead.
How do you calculate the margin on a diet menu? (step by step)
Gather all costs per dish
Note all ingredient costs including superfoods, organic products and specialty proteins. Don't forget packaging costs either - these are often higher for healthy menus due to sustainable materials.
Calculate your net revenue after platform fees
Subtract the platform commission (15-30%) from your selling price. This is the amount you actually receive. Always calculate with the price excluding VAT.
Divide ingredient costs by net revenue
Use the formula: (Total ingredient costs / Net revenue) × 100. For diet menus, 35-45% food cost is normal due to more expensive ingredients.
