Most dark kitchen operators nail their ingredient costs but completely mess up their rent calculations. You can't just focus on food expenses and hope your fixed costs disappear. Every single order needs to contribute toward covering that monthly rent payment.
Why you can't ignore rent in cost pricing
Your dark kitchen doesn't have dining room customers, but that rent bill shows up every month anyway. Skip this calculation and you'll think you're making money on each dish while your bank account tells a different story.
⚠️ Note:
Rent doesn't care about your order volume. Hit 100 orders or 500 orders this month - you still owe the same amount. That's exactly why hitting your volume targets matters so much.
The rent-per-order math
Take your monthly rent and divide it by realistic order projections. That's your baseline.
Formula: Monthly rent ÷ Expected monthly orders = Rent cost per order
💡 Example:
Monthly rent: €2,400
Projected orders: 800
Result: €2,400 ÷ 800 = €3.00 rent per order
Building your complete cost structure
Rent is just one piece. Your real cost per order includes everything you need to fulfill that delivery:
- Raw ingredients (your actual food cost)
- Packaging materials (boxes, bags, utensils)
- Rent allocation per order
- Platform commissions (usually 15-30%)
💡 Real numbers breakdown:
Chicken tikka masala order:
- Food ingredients: €4.20
- Container and bag: €0.75
- Rent share: €3.00
- Total base costs: €7.95
Sale price €15.90 → Platform takes 25% = €3.98
Your profit: €11.92 - €7.95 = €3.97
Volume scenarios change everything
Since rent stays fixed, your per-order cost shifts dramatically with volume changes. From analyzing actual purchasing data across different restaurant types, I've seen operators go from profitable to broke just because their volume assumptions were wrong. Run multiple scenarios:
- Slow month: 500 orders = €4.80 rent each
- Target month: 800 orders = €3.00 rent each
- Busy month: 1,200 orders = €2.00 rent each
⚠️ Note:
Build your pricing around the slow month numbers. If you only make money during peak periods, you're setting yourself up for trouble.
Don't forget your other fixed expenses
Rent isn't your only monthly fixed cost. These add up fast:
- Utilities (electricity for equipment, gas for cooking)
- Communications (internet, phone service)
- Business insurance
- Equipment wear and replacement
Bundle all monthly fixed costs together, then divide by your conservative order estimate.
💡 Complete picture:
- Rent: €2,400
- Utilities: €400
- Internet/phone: €80
- Insurance: €120
- Combined fixed costs: €3,000
At 800 orders monthly: €3.75 fixed cost per order
Keep track with digital tools
Volume changes, seasonal patterns, and menu updates make manual tracking a nightmare. Digital cost tracking saves you from constantly recalculating by hand and helps you spot trends before they hurt your bottom line.
How do you calculate rent costs in your cost price? (step by step)
Determine your total fixed monthly costs
Add up: rent, energy, internet, insurance and other fixed costs. This gives you total monthly fixed costs that need to be passed on.
Estimate realistic monthly volume
Calculate your expected number of orders per month. Use historical data or make a conservative estimate. Work with different scenarios (low/medium/high volume).
Calculate fixed costs per order
Divide your total monthly fixed costs by the expected number of orders. Add this amount to your ingredient and packaging costs for your total cost price.
✨ Pro tip
Build your break-even calculations using 70% of your projected monthly volume over a 90-day average. This cushion protects you during inevitable slow periods and seasonal dips.

Frequently asked questions
Do I need to include rent costs if I cook from home for delivery?
Home operations still have real costs - higher utility bills, kitchen equipment wear, potential renovations for commercial use. Calculate a realistic monthly amount even without separate rent payments.
What if my monthly order volume swings wildly?
Base your break-even calculations on your worst performing month. Anything above that becomes bonus profit, and you won't go negative during slow periods.
How often should I recalculate my cost per order?
Review your actual vs projected volume monthly. If you're consistently hitting different numbers than expected, adjust both your cost calculations and menu pricing accordingly.
What if I share kitchen space with other delivery businesses?
Split fixed costs based on actual usage - hours, storage space, equipment access. Document the arrangement clearly so everyone knows their fair share of expenses.
