Central meal production transforms your cost structure by spreading fixed expenses across thousands of portions daily. Smart operators achieve 15-30% cost reductions through bulk purchasing, specialized labor, and shared overhead. You'll need specific volume thresholds to make this transition profitable.
What are economies of scale in central production?
Your cost per portion drops as production volume increases. Central meal production delivers savings through three key channels:
- Purchasing: Bulk orders unlock 10-25% supplier discounts
- Labor: Specialized teams work faster in dedicated facilities
- Overhead: Equipment, rent, and utilities divide across more portions
The basic formula for economies of scale
Your cost per portion calculation looks like this:
Cost per portion = (Fixed costs + Variable costs) ÷ Number of portions
💡 Example:
Central kitchen serving 3 school cafeterias, 1,500 daily portions:
- Daily fixed costs: €800 (rent, utilities, core staff)
- Variable costs: €3.20 per portion (ingredients, additional labor)
- Total: (€800 + (1,500 × €3.20)) ÷ 1,500 = €4.73 per portion
Compare that to €5.40 per portion across 3 separate kitchens
Calculating purchasing advantages
Volume purchasing typically delivers 10-25% discounts. Calculate your savings:
Purchasing savings = (Previous price - New bulk price) × Total volume
💡 Purchasing advantage example:
Three locations combined need 500kg meat weekly:
- Individual orders: €12.00 per kg
- Bulk pricing: €9.60 per kg (20% volume discount)
- Weekly savings: (€12.00 - €9.60) × 500kg = €1,200
Annual meat savings alone: €62,400
Labor efficiency and specialization
Specialized chefs produce 200-300 portions hourly in central kitchens versus 100-150 in smaller facilities. But here's one of the most common blind spots in kitchen management: operators forget that transportation adds €0.20-€0.50 per portion to their costs.
⚠️ Note:
Transportation costs vary dramatically by distance and delivery frequency. Factor €0.20-€0.50 per portion depending on your route efficiency and fuel costs.
Determining the break-even point
Central production needs minimum volume to justify setup costs. Find your break-even:
Break-even volume = Additional fixed costs ÷ (Per-portion savings - Transport costs)
💡 Break-even calculation:
Additional central kitchen fixed costs: €2,000 daily
- Scale savings per portion: €0.80
- Transport cost per portion: €0.30
- Net benefit: €0.50 per portion
Break-even point: €2,000 ÷ €0.50 = 4,000 daily portions
Quality and shelf life
Extended time between cooking and service affects taste and nutrition. Account for specialized packaging, refrigerated transport, and potential waste from quality degradation in your calculations.
Digital support for central production
Central operations demand precise recipe costing and location-specific allocation tracking. You'll need exact portion costs and volume-based pricing across all sites. Tools like KitchenNmbrs manage centralized recipes and automatically adjust cost calculations for different production volumes.
How do you calculate economies of scale? (step by step)
Inventory current costs per location
Create an overview of all fixed and variable costs per location. Add up: kitchen space rent, energy, staff, purchasing, and overhead. Calculate the cost per portion for each location separately.
Calculate central production costs
Determine the costs of a central kitchen: rent, equipment, additional staff, and transportation costs. Calculate how many portions you need at minimum to recover these fixed costs.
Compare cost per portion
Divide the total central production costs by the total number of portions. Compare this with the average cost per portion of your current locations. The difference is your economy of scale per portion.
Calculate purchasing advantages
Request quotes from suppliers for larger volumes. Calculate the savings per ingredient and multiply by your annual volume. This gives you total purchasing advantage per year.
Determine break-even point
Divide your extra fixed costs by the net savings per portion. This gives you the minimum number of portions you need to make central production profitable.
✨ Pro tip
Test your calculations with a 90-day pilot program focusing on 2-3 high-volume menu items before committing to full central production. Track actual transport costs, quality retention, and labor savings to validate your break-even projections.

Frequently asked questions
From how many portions per day does central production make sense?
Most operations hit profitability around 2,000-3,000 daily portions, depending on fixed costs and delivery distances. Below this threshold, transportation and logistics expenses typically exceed your economies of scale benefits.
What are typical purchasing discounts at large volumes?
Fresh products usually offer 10-15% volume discounts while shelf-stable items can reach 15-25% savings. Meat, dairy, and produce suppliers often negotiate differently than dry goods vendors. Always compare multiple supplier quotes to maximize your purchasing power.
Can I combine central production with local preparation?
Absolutely - many successful operations do prep work centrally (washing, cutting, marinating) then finish dishes locally. This captures labor efficiencies on time-intensive tasks while preserving freshness and menu flexibility at each location.
