Running a delivery kitchen feels like trying to fill a bucket with invisible holes. Your dishes appear profitable on paper, but platform fees, packaging costs, and processing charges quietly drain your margins. Most dark kitchen operators believe they're running 30% food costs while their actual costs climb to 50% or higher.
The hidden costs of delivery
Delivery operations carry cost layers that traditional restaurants never encounter. These expenses pile up and can wipe out your profit margins completely:
- Platform fees: 15-30% of your order value
- Packaging costs: €0.50-€2.50 per order
- Payment processing: 2-4% of order value
- Marketing fees: extra promotions and visibility
⚠️ Watch out:
Platform fees get calculated on the total order value including VAT. This makes them more expensive than they first appear.
The real cost calculation for delivery
For each delivery dish you need to use this formula:
Total cost price = Ingredients + (Packaging per portion) + (Platform fee × Selling price incl. VAT) + Payment processing
💡 Example: Pasta Carbonara
Selling price: €16.50 incl. VAT
- Ingredients: €4.20
- Packaging (container + lid + bag): €0.75
- Platform fee (25%): €4.13
- Payment processing (3%): €0.50
Total costs: €9.58 on €15.14 excl. VAT = 63% cost price!
Signals of unprofitable dishes
Look for these warning signs in your delivery menu. One of the most common blind spots in kitchen management is missing how these factors multiply against each other:
- Low order values: Platform fee hits harder on small orders
- Many separate items: More packaging costs per euro of revenue
- Complex packaging: Sauces separate, multiple containers needed
- Heavy items: Larger containers cost more
💡 Example: Problematic dish
Salad for €9.50:
- Ingredients: €2.80
- Packaging + dressing separate: €1.20
- Platform fee (25%): €2.38
- Payment processing: €0.29
Total: €6.67 on €8.72 excl. VAT = 76% cost price - losing money!
Weekly analysis routine
Track these numbers every week for your top 10 delivery dishes:
- Number sold: Focus on high-volume items first
- Average order value: Low AOV = higher relative platform costs
- Total cost price incl. all fees: Must stay under 50%
- Profit contribution per dish: Selling price minus all costs
⚠️ Watch out:
Platform fees can jump overnight. Check monthly that your prices still match the actual fees charged.
Action on unprofitable dishes
If a dish consistently runs above 50% total cost price, you have three options:
- Raise the price: Test small increments of €1-2
- Optimize packaging: Cheaper containers, fewer components
- Remove from menu: Focus on profitable dishes
💡 Example: Optimization
Burger menu from €12.50 to €14.50:
- Platform fee increases by €0.50
- But you earn €1.50 extra net
- Cost price drops from 58% to 52%
Result: From unprofitable to profitable
How do you detect unprofitable delivery dishes? (step by step)
Gather all costs per dish
Note for each dish: ingredient costs, packaging costs (add up all containers, lids, bags), current platform fee percentage from your delivery partner. Don't forget payment processing fee (usually 2-4%).
Calculate total cost price including all fees
Add up: ingredients + packaging + (platform fee × selling price incl. VAT) + payment processing. This is your actual cost price per dish. Divide this by your selling price excl. VAT for the cost price percentage.
Identify dishes above 50% total cost price
All dishes with more than 50% total cost price are unprofitable. Focus first on your best-selling items - those cost you the most money. Make a list of action items: raise prices, optimize packaging, or remove from menu.

Frequently asked questions
What is an acceptable cost price for delivery dishes?
For delivery operations, aim for total cost prices between 40-50%. Anything above 50% means you're operating at a loss. Below 40% might signal you're overpriced for your market.
Should I include VAT in the platform fee calculation?
Yes, platform fees get calculated on the full customer payment including VAT. A 25% fee on €16.50 incl. VAT costs you €4.13, not calculated on the pre-VAT amount.
How often should I analyze dish profitability?
Review your top 10 dishes weekly and your complete menu monthly. Platform fees and packaging costs shift without advance notice, so regular monitoring prevents profit leaks.
What if most dishes show up as unprofitable?
Your pricing structure needs adjustment for delivery economics. Raise prices systematically by €2-3 across the board and track volume changes. Delivery operations cost more than dine-in service.
