Most restaurant owners think they can just split costs evenly across their hybrid model - that's dead wrong. Each revenue stream has wildly different cost structures and profit margins. You'll end up with one branch secretly funding the others while your overall profits tank.
Understanding the three cost structures
Your hybrid model splits into three distinct cost worlds. Restaurant operations burn cash on service and ambiance, dark kitchens focus purely on speed and efficiency, while catering demands flexibility and transport logistics.
💡 Example cost structure:
Restaurant (100 seats) + Dark kitchen (delivery) + Catering (events):
- Restaurant rent: €8.000/month
- Extra kitchen space dark kitchen: €2.500/month
- Catering van + equipment: €1.200/month
- Restaurant staff: €18.000/month
- Dark kitchen staff: €6.000/month
- Catering staff (variable): €3.000/month
Total fixed costs: €38.700/month
Shared vs. specific costs
You can't just divide everything by three. Some expenses get shared across all operations, others hit specific branches hard.
- Shared costs: Main kitchen, chef, basic ingredients, utilities
- Restaurant specific: Service, glassware, tableware, bar, atmosphere
- Dark kitchen specific: Packaging, platform fees (15-30%), delivery costs
- Catering specific: Transport, setup, extra staff on-site
Passing through platform fees and commissions
Dark kitchen and catering operations face brutal external costs that'll kill your margins if you ignore them.
⚠️ Note:
Platform fees from Thuisbezorgd and Uber Eats can be 15-30% of your order value. Factor this into your cost price directly, not as some vague 'marketing expense'.
Cost allocation per revenue source
Fair distribution means using actual data, not guesswork. Revenue percentages or labor hours work as solid allocation keys - based on real restaurant P&L data we've analyzed, most operators get this completely backwards.
💡 Example allocation:
Monthly revenue €120.000 distributed as:
- Restaurant: €70.000 (58%)
- Dark kitchen: €30.000 (25%)
- Catering: €20.000 (17%)
Shared costs of €25.000 distributed according to these percentages.
Measuring profitability per branch
Track each branch like it's a separate business. Catering usually delivers the highest margins per euro, but your restaurant generates consistent absolute profits.
- Restaurant: Lower margin (35-45%) but rock-solid revenue
- Dark kitchen: Higher food costs from packaging, but you'll save on labor
- Catering: Highest possible margin (50-60%) with wildly variable revenue
Planning seasons and peaks
Each branch hits peak demand at different times. Restaurants crush weekends, catering explodes in spring, dark kitchens run steady year-round.
⚠️ Note:
December sees catering at maximum capacity for Christmas events, while dark kitchen orders often drop as families cook at home. Plan your cash flow for these swings.
Digital administration for overview
Three revenue streams create three times the data chaos. You need systems that track recipes, cost prices and margins separately for each branch without drowning you in spreadsheet hell.
How do you calculate operational costs? (step by step)
Inventory all fixed costs per month
List rent, staff, insurance, utilities, depreciation. Divide into 'shared' (kitchen, chef) and 'specific' (service, packaging, transport).
Calculate variable costs per revenue source
Dark kitchen: platform fees 15-30%, packaging €0.50-2.00 per order. Catering: transport, extra staff, materials on-site. Restaurant: normal food cost + service.
Distribute shared costs by revenue ratio
If restaurant delivers 60% of revenue, it gets 60% of shared costs. Recalculate each month based on actual revenue distribution.
Measure profitability per branch separately
Calculate for each branch: Revenue - Food cost - Allocated labor costs - Specific costs - Share of shared costs = Operating result per branch.
Set minimum revenue per branch
Calculate the break-even point per branch. Below what monthly revenue does a branch become unprofitable? Use this to make decisions about growth or discontinuation.
✨ Pro tip
Track your labor allocation across all three branches for 4 weeks straight - you'll discover catering events require 40% more prep time than you're currently calculating into your pricing.

Frequently asked questions
How do I pass through platform fees in my menu price?
With 25% platform fees, your selling price needs to jump 33% higher than normal to maintain margins. That €20 restaurant dish becomes €26.67 on Thuisbezorgd. Most operators price too low and wonder why delivery kills their profits.
Which branch typically delivers the highest ROI?
Catering usually hits 50-60% margins but revenue swings wildly by season. Restaurant operations provide stability with 35-45% margins. Dark kitchens get squeezed by platform fees but generate consistent volume year-round.
Should I track ingredient costs separately for each branch?
Absolutely, especially for packaging and portion sizes. Dark kitchen orders need takeout containers, catering requires larger portions and transport-safe packaging, while restaurant costs include presentation elements. Same recipe, completely different cost structure.
