I'll admit it - shared kitchen food costing nearly killed my first concept. You're splitting space, equipment, and sometimes ingredients with another business, which makes tracking your real costs a nightmare. Miss this calculation and you'll wonder why your bank account's empty despite decent sales.
What makes shared kitchen food cost complex?
You're juggling shared expenses that need splitting across your production. And it's not just ingredients - you're covering a portion of rent, utilities, gear, and sometimes labor too.
⚠️ Watch out:
Most shared kitchen operators only track ingredient costs and ignore shared expenses. Your food cost appears artificially low, which is dangerous.
Calculate your total costs per dish
Your shared kitchen food cost breaks down into three chunks:
- Direct ingredient costs: every component in your dish
- Shared kitchen expenses: your portion of rent, utilities, equipment
- Packaging costs: containers, bags, labels for delivery
💡 Example calculation:
You produce 200 pasta portions weekly in a shared kitchen:
- Ingredients per portion: €4.50
- Shared kitchen expenses: €800/week
- Packaging per portion: €0.75
Shared expenses per portion: €800 ÷ 200 = €4.00
Total food cost per portion: €4.50 + €4.00 + €0.75 = €9.25
Divide shared kitchen costs fairly
The trickiest part? Splitting shared expenses equitably. Here are your options:
- Production hours basis: how long do you occupy the kitchen?
- Revenue basis: higher earners pay more
- Portion count basis: straightforward but sometimes unfair
- Fixed split: 50/50 regardless of actual usage
💡 Example division by hours:
Weekly kitchen expenses: €1,200
- Your kitchen time: 30 hours/week
- Partner's time: 20 hours/week
- Combined: 50 hours/week
Your portion: (30 ÷ 50) × €1,200 = €720/week
Keep track of production data
Accurate food costing requires tracking:
- Daily and weekly portion counts
- Kitchen hours logged
- Equipment usage (ovens, fryers, mixers)
- Energy consumption (gas, electricity)
Without this data, you can't split costs fairly. You'll have no clue what your dishes actually cost - the kind of thing you only learn after closing your first month at a loss.
⚠️ Watch out:
Establish peak time agreements upfront. If you both need Friday kitchen access, expect extra costs for additional equipment or extended rental periods.
Calculate your actual food cost percentage
With complete cost data, you can determine your real food cost percentage:
Food cost % = (Total costs per portion ÷ Selling price excl. VAT) × 100
💡 Complete calculation:
Pasta sells for €16.50 (including 9% VAT)
- Selling price excluding VAT: €16.50 ÷ 1.09 = €15.14
- Total costs: €9.25 (from earlier example)
Food cost: (€9.25 ÷ €15.14) × 100 = 61.1%
That's dangerously high! Target food costs run 28-35%.
Optimize your shared kitchen food cost
If your food cost exceeds targets, try these approaches:
- Increase selling prices: most immediate fix
- Reduce ingredient costs: find cheaper suppliers, adjust recipes
- Scale up production: more portions = lower per-unit costs
- Improve kitchen efficiency: work smarter = fewer hours
For shared kitchens, scaling production often works best. Fixed costs remain constant, but you distribute them across more portions.
How do you calculate food cost in a shared kitchen? (step by step)
Inventory all costs
List all costs: ingredients, your share of kitchen costs (rent, energy, equipment), packaging materials and any additional services. Make agreements about how you divide shared costs.
Measure your production and kitchen usage
Keep track of how many portions you make per week and how many hours you use the kitchen. You need this to divide shared costs fairly across your production.
Calculate costs per portion
Add up ingredient costs, your share of shared costs (per portion) and packaging costs. These are your total costs per dish.
Calculate food cost percentage
Divide your total costs per portion by your selling price (excl. VAT) and multiply by 100. If this comes out above 35%, you need to adjust your prices or costs.
✨ Pro tip
Track your shared costs weekly for the first 8 weeks, then adjust your cost split based on real usage patterns. Most partnerships start with rough estimates that need fine-tuning.

Frequently asked questions
How do I divide kitchen costs fairly with my shared kitchen partner?
Base it on actual usage - track your production hours and split costs proportionally. If you work 30 hours and your partner works 20 hours, you cover 60% of expenses.
Should I include packaging costs in my food cost?
Absolutely, especially for delivery operations. Packaging is a product cost just like ingredients. Plan for €0.50 to €1.50 per portion covering containers, bags and labels.
What if my food cost exceeds 50% in a shared kitchen?
Your shared expenses are too high or your prices too low. Scale up production to distribute costs better, or increase your selling prices. Delivery concepts can typically command higher prices than dine-in.
How do I calculate energy costs in a shared kitchen?
Exact measurement is tough. Create agreements based on equipment usage (oven versus refrigerator) or take a percentage of total energy bills matching your production hours.
Can I buy ingredients together with my shared kitchen partner?
Yes, but track individual usage carefully. Establish clear ordering and settlement agreements. Joint purchasing can reduce costs through volume discounts.
What happens if we use different equipment that consumes varying amounts of energy?
Factor equipment intensity into your cost split. Heavy users of ovens, fryers, or freezers should pay proportionally more than those using basic prep equipment.
