Most ghost kitchen operators think they're saving money by skipping the dining room - but that's only half the story. Your delivery-only setup actually creates higher equipment density and energy demands that can quietly eat into profits. These hidden costs often represent 15-25% of revenue, making precise calculation critical for sustainable margins.
Why ghost kitchen costs differ dramatically
Ghost kitchens operate with a fundamentally different cost structure than traditional restaurants. You eliminate service staff and dining space expenses, but face higher costs for:
- Increased cooling equipment per square meter (separate refrigerators for different menu concepts)
- Additional heating equipment (multiple ovens, warming cabinets, fryers)
- Specialized packaging equipment (vacuum sealers, heat lamps, warming drawers)
- Elevated energy consumption from continuous operation
⚠️ Common mistake:
Too many ghost kitchen operators calculate margins using only ingredient costs. This creates dangerously misleading profit projections that don't reflect reality.
Calculate energy costs per appliance
Begin with a complete equipment inventory. Record the power consumption (in kW) and daily operating hours for each piece. Here's your calculation formula:
Energy costs = Power (kW) × Operating hours × Energy rate (€/kWh) × Monthly operating days
💡 Real example:
Ghost kitchen equipment costs (10 hours daily, 26 operating days, €0.30/kWh):
- Combi oven 6kW: 6 × 10 × €0.30 × 26 = €468
- Deep fryer 3kW: 3 × 8 × €0.30 × 26 = €187
- Dual refrigeration units 0.5kW each: 1 × 24 × €0.30 × 30 = €216
- Ventilation system 2kW: 2 × 12 × €0.30 × 26 = €187
Monthly energy total: €1,058
Calculate equipment depreciation accurately
Equipment loses value and eventually requires replacement. Factor these costs into your pricing structure using these depreciation timelines:
- Refrigeration equipment: 7 years
- Ovens and fryers: 5 years
- Small appliances: 3 years
- Packaging machinery: 5 years
Monthly depreciation = Purchase price ÷ (Equipment lifespan in years × 12)
💡 Depreciation breakdown:
Equipment purchase costs and monthly depreciation:
- Combi oven €8,000: €8,000 ÷ (5×12) = €133/month
- Deep fryer €2,500: €2,500 ÷ (5×12) = €42/month
- Dual refrigerators €3,000: €3,000 ÷ (7×12) = €36/month
- Ventilation system €4,000: €4,000 ÷ (7×12) = €48/month
Total monthly depreciation: €259
Factor in maintenance and repairs
Reserve 10-15% of your depreciation costs for maintenance and unexpected repairs. From years of working in professional kitchens, I've seen how ghost kitchen equipment operates under more intensive conditions than traditional restaurant setups, leading to accelerated wear.
Using our example: €259 × 15% = €39 monthly for maintenance reserves.
Calculate total additional costs per order
Sum all overhead costs and divide by your average monthly order volume:
💡 Final calculation:
Total monthly overhead distributed across 2,000 orders:
- Energy costs: €1,058
- Equipment depreciation: €259
- Maintenance reserve: €39
- Combined total: €1,356
Cost per order: €1,356 ÷ 2,000 = €0.68
This €0.68 must be added to your cost calculations alongside ingredients, packaging materials, and delivery platform commissions.
Plan for seasonal demand variations
Ghost kitchens typically experience significant seasonal fluctuations - busy periods during winter and holidays, slower summer months. Always calculate using your lowest monthly volume to maintain healthy margins year-round.
⚠️ Critical consideration:
Fixed overhead remains constant while order volume fluctuates. Base your pricing on your slowest month to avoid margin erosion during quiet periods.
How do you calculate the extra costs of your ghost kitchen?
Create an equipment inventory
Write down all appliances with their power consumption in kW and daily usage time. Don't forget cooling - it runs 24/7. Check the nameplate for exact power consumption.
Calculate monthly energy costs
Multiply power × usage time × energy price × working days. For cooling calculate with 30 days per month. Add up all appliances.
Calculate depreciation and maintenance
Divide purchase price by lifespan in months for depreciation. Add 10-15% for maintenance. These are your fixed monthly costs.
Distribute over number of orders
Divide total monthly costs by your average orders per month. Use your lowest month for a safe margin. Include this amount in every cost price.
✨ Pro tip
Install individual smart meters on your top 3 energy-consuming appliances for 30 days to identify exact usage patterns. You'll discover which equipment drives costs and can optimize operating schedules to reduce peak-hour energy charges.

Frequently asked questions
What percentage of revenue should energy and equipment costs represent?
Ghost kitchens typically see 15-25% of revenue consumed by energy, depreciation, and maintenance costs combined. Traditional restaurants usually range from 10-15%, but ghost kitchens pack more equipment into smaller spaces.
Should rent be included in these equipment cost calculations?
No, treat rent as a separate line item in your cost structure. Focus only on the incremental costs directly related to equipment operation and energy consumption. Allocate rent separately across your order volume.
How do I split costs when running multiple brands from one kitchen?
Allocate costs proportionally based on actual usage patterns. If Brand A generates 60% of orders, assign 60% of energy and equipment costs to that brand. For equal equipment usage, split costs evenly between brands.
What's the ideal frequency for updating these cost calculations?
Review your energy bills and order volumes quarterly at minimum. Energy price increases or declining order volumes directly impact your per-order costs, requiring immediate pricing adjustments to maintain profitability.
Can these equipment and energy costs be tax-deductible?
Yes, both depreciation and energy expenses qualify as legitimate business deductions. Maintain detailed records of all equipment purchases and energy bills. Consult your accountant for specific tax optimization strategies.
How do I handle equipment that serves multiple menu items differently?
Track actual usage hours per menu category rather than splitting evenly. A pizza oven used 70% for pizzas and 30% for appetizers should have costs allocated accordingly. This prevents cross-subsidization between menu items.
What happens if my equipment breaks down outside the depreciation schedule?
Early equipment failure still requires replacement costs to be recovered through pricing. Adjust your remaining depreciation schedule to account for unexpected replacement, and consider increasing your maintenance reserve percentage for similar equipment.
