Many delivery owners think food cost calculation is the same as dine-in restaurants - that's dead wrong. Packaging materials, spoilage rates, and platform dynamics create hidden costs that can destroy your margins. The real calculation requires factoring in waste risk percentages that most operators completely ignore.
Why delivery menus have different food costs
Delivery operations face unique cost pressures that dine-in restaurants don't deal with. You're paying for containers, dealing with higher spoilage from fresh ingredients, and managing platform commission structures.
⚠️ Note:
Platform fees are not part of food cost, but they are part of your overall cost structure. Calculate them separately.
All costs you need to include
For accurate food cost calculation, track these expense categories:
- Ingredients: all products that go into the dish
- Packaging: containers, bags, stickers, cutlery
- Waste risk: extra percentage for fresh daily products
- Portioning: accounting for standard portions
💡 Example: Salad with fresh daily ingredients
Menu price: €12.50 incl. 9% VAT = €11.47 excl. VAT
- Lettuce, tomato, cucumber: €2.80
- Chicken fillet: €1.90
- Dressing: €0.30
- Packaging (container + bag): €0.45
- Waste risk 8%: €0.44
Total costs: €5.89 = 51% food cost
Fresh daily ingredients: extra waste risk
Fresh products spoil faster than shelf-stable items. You need to build in a 5-10% buffer for inevitable waste.
High-risk ingredients that spoil quickly:
- Fresh lettuce and leafy greens
- Soft fruits (tomato, avocado)
- Fresh herbs
- Fish and seafood
- Fresh dairy
💡 Calculating waste risk:
Total ingredient costs: €5.00
Waste risk 8%: €5.00 × 0.08 = €0.40
Real ingredient costs: €5.40
Packaging costs per order
Packaging represents a direct hit to your margins that many operators overlook. Every container, bag, and utensil set adds up - a mistake that costs the average restaurant EUR 200-400 per month in untracked expenses.
Typical packaging expenses:
- Cardboard container: €0.15 - €0.35
- Plastic container: €0.08 - €0.20
- Paper bag: €0.05 - €0.12
- Stickers/labels: €0.02 - €0.05
- Cutlery per set: €0.08 - €0.15
Calculate platform fees separately
Platform commissions (15-30% of order value) aren't food costs, but they're critical for profitability analysis. Track them as a separate line item in your cost breakdown.
💡 Total picture for delivery dish:
Selling price: €12.50
- Platform fee (25%): €3.13
- Food cost incl. packaging: €5.89
- Labor and overhead: €2.50
Profit: €0.98 = 8% margin
Common food cost percentages for delivery
Delivery operations typically run higher food costs than traditional restaurants because of packaging and waste factors:
- Regular restaurant: 28-35% food cost
- Delivery/dark kitchen: 32-42% food cost
- Fresh daily salads: 40-50% food cost
These higher percentages make sense since you're saving on front-of-house labor and rent, but platform fees eat into margins.
Tools for automatic calculation
Manual calculations are time-consuming and error-prone. Food cost software automatically computes your total dish costs including packaging and waste percentages.
You input recipes with ingredients, add packaging as line items, and the system calculates real-time costs per dish. Tools like KitchenNmbrs handle these calculations automatically.
How do you calculate food cost of delivery menus? (step by step)
Gather all ingredient costs
Make a list of all ingredients that go into the dish. Note the exact amount per portion and the purchase price per unit. Don't forget small ingredients like herbs, oil and salt.
Add packaging costs
Calculate what all packaging materials cost per dish: container, bag, stickers, cutlery. Add these to your ingredient costs as one total amount.
Add waste risk
For fresh daily ingredients, calculate an extra 5-10% cost for waste. Multiply your total ingredient costs by 1.05 to 1.10 depending on shelf life.
Calculate food cost percentage
Divide your total costs (ingredients + packaging + waste risk) by your selling price excluding VAT. Multiply by 100 for the percentage.
✨ Pro tip
Track actual waste for 2 weeks by weighing discarded ingredients daily. Most delivery kitchens underestimate spoilage by 3-5%, which throws off their entire cost structure.

Frequently asked questions
Should I include platform fees in my food cost calculation?
No, platform fees are a separate expense category. Food cost only covers ingredients and packaging materials. Track platform commissions as a distinct line item for profitability analysis.
How high can my food cost be with delivery?
Delivery food costs typically run 32-42%, higher than dine-in restaurants due to packaging and spoilage. Fresh salad concepts can hit 50% and still be profitable.
What waste percentage should I use for fresh daily ingredients?
Calculate 8-10% waste risk for leafy greens, herbs, and soft vegetables. Shelf-stable items like grains need only 3-5% buffer for waste.
How often should I recalculate my delivery food cost?
Review costs monthly since ingredient prices fluctuate frequently. Fresh produce especially can swing 15-20% month-to-month, impacting your margins significantly.
