The minimum occupancy for a profitable company canteen depends on your fixed costs, food cost and average transaction value. Many canteens operate at a loss because they miscalculate the break-even occupancy. Here's how to calculate exactly how many guests you need minimum to make the canteen profitable.
What determines the minimum occupancy?
A company canteen has a different cost structure than a restaurant. You usually have a fixed contract with the company, which makes your revenue predictable but also limited.
- Fixed costs: staff, rent, energy, equipment
- Variable costs: ingredients, packaging
- Average transaction value: what an employee spends on average
- Food cost percentage: usually higher than restaurants (35-45%)
The break-even formula for canteens
The basic formula is simple but crucial:
💡 Formula:
Minimum occupancy per day = Fixed costs per day / (Average transaction value - Variable costs per transaction)
Where variable costs per transaction = food cost + packaging + any transaction fees.
Gather your fixed costs per day
Add up all costs you have, regardless of how many guests come:
- Staff (chef, service, dishwashing)
- Rent kitchen and canteen space
- Energy (gas, water, electricity)
- Equipment depreciation
- Insurance and administration
💡 Example fixed costs:
Canteen for 200-person company:
- Staff: €450/day (2 FTE)
- Rent: €85/day
- Energy: €65/day
- Other: €25/day
Total fixed costs: €625/day
Calculate your variable costs per guest
These are costs that increase with each additional guest:
💡 Example variable costs:
Average transaction value: €8.50
- Food cost (40%): €3.40
- Packaging: €0.35
- Payment fees: €0.15
Total variable costs: €3.90 per guest
Calculate the minimum occupancy
Now you can calculate the break-even occupancy:
💡 Break-even calculation:
Fixed costs: €625/day
Margin per guest: €8.50 - €3.90 = €4.60
Minimum occupancy: €625 ÷ €4.60 = 136 guests/day
With fewer than 136 guests per day, this canteen operates at a loss. After managing kitchen operations for nearly a decade, I've seen too many canteens fail because they never calculated this basic number.
⚠️ Note:
This is break-even, not profit. For 10% profit you need 150+ guests. Always calculate a buffer.
Factors that influence your occupancy
Different circumstances can increase or decrease your minimum occupancy:
- Seasonal fluctuations: vacation periods, working from home
- Competition: other dining options nearby
- Menu composition: more expensive dishes = higher margin
- Efficiency: less waste lowers food cost
Strategies to reach break-even
If your current occupancy is below the break-even point, you have these options:
💡 Options for low occupancy:
- Increase average transaction value (more items, premium options)
- Lower food cost (more efficient purchasing, less waste)
- Optimize staff deployment (flexible hours)
- Find additional revenue (catering, events)
A food cost calculator helps you track your recipe costs precisely, so you know exactly which dishes generate the highest margins for your canteen.
How do you calculate the minimum occupancy? (step by step)
Gather all fixed costs per day
Add up staff, rent, energy and other costs you have regardless of the number of guests. Divide monthly costs by 22 working days for the daily amount.
Calculate variable costs per guest
Add food cost, packaging and transaction costs per average transaction. Subtract this from your average transaction value to get your margin per guest.
Divide fixed costs by margin per guest
The result is your break-even occupancy per day. Calculate a 10-15% buffer for unexpected costs and desired profit.
✨ Pro tip
Track occupancy patterns for each weekday separately over a 6-week period - you'll often find Mondays and Fridays dip 20-30% below your Tuesday-Thursday averages. This data helps you adjust staffing and food prep more precisely.

Frequently asked questions
What is a realistic food cost for a company canteen?
Canteens often have higher food costs than restaurants: 35-45% is common. This is due to lower selling prices and less luxurious ingredients.
How often should I recalculate my break-even occupancy?
Check this monthly, especially after changes in staff costs, rent or supplier prices. Recalculation is also needed with new menus.
What if my current occupancy is below break-even?
You have three options: increase the average transaction value, lower costs, or find additional revenue such as catering for meetings.
Should I include VAT in my calculation?
Always calculate excluding VAT for your cost price calculation. Canteens charge 9% VAT on food and 21% on alcoholic beverages.
