How do I calculate the financial feasibility of delivering hot lunch to office buildings?

📝 KitchenNmbrs · updated 13 Mar 2026

Many restaurant owners think office lunch delivery is just regular delivery with bigger orders - that's completely wrong. You're dealing with bulk production schedules, specialized heat retention equipment, and completely different risk profiles. The math changes dramatically once you factor in the real costs.

Cost structure for office lunch

Office lunch delivery operates on fundamentally different economics than regular delivery. You're producing in bulk batches, hitting precise delivery windows, and using specialized packaging that keeps food hot for 30+ minutes. These operational differences reshape your entire cost structure.

💡 Example cost breakdown per lunch:

  • Ingredients: €3.50
  • Packaging (heat retention box): €0.80
  • Delivery costs: €1.20
  • Labor (production + delivery): €2.00

Total cost price: €7.50

Calculate minimum selling price

Office lunch demands a 35% gross profit minimum. You can't survive on the thin margins that work for regular delivery - the fixed costs and customer concentration risks are too high.

💡 Minimum selling price calculation:

Cost price: €7.50
Desired gross profit: 35%

Formula: Cost price / (1 - Profit margin) = Minimum selling price

€7.50 / 0.65 = €11.54 excl. VAT

Selling price incl. 9% VAT: €12.58

Volume impact on profitability

Office lunch is a high-stakes volume game. Your break-even point sits much higher than regular delivery because you're carrying fixed costs for specialized equipment and larger vehicles that run regardless of your daily sales numbers.

  • Minimum volume: 50 lunches per day for break-even
  • Comfortable volume: 100+ lunches for solid profitability
  • Fixed costs per day: €150-200 (equipment, larger vehicle, extra staff)

⚠️ Important:

Offices typically order for entire teams (20-50 people). Lose one major client and you've instantly lost 30-40% of your volume. You need at least 5-10 office clients to spread this concentration risk.

Specific costs for office lunch

Beyond standard restaurant costs, office lunch creates unique expense categories. Miss these in your calculations and you'll be bleeding money within weeks - a pattern we see repeatedly in restaurant financials.

  • Heat retention packaging: €0.60-1.00 per lunch (triple the cost of regular containers)
  • Delivery vehicle: Larger capacity needed, €50-80 extra daily
  • Heat retention equipment: Depreciation runs €30-50 per day
  • Extra labor: Coordination, on-site distribution, return logistics
  • Insurance: Higher liability coverage for bulk food service

💡 Example daily extra costs:

  • Larger delivery vehicle: €60
  • Heat retention equipment: €40
  • Extra staff (2 hours): €50
  • Insurance/administration: €20

Total extra: €170 per day

At 80 lunches = €2.13 extra per lunch

Seasonal patterns and planning

Office lunch volume swings wildly with corporate calendars. Summer months, remote work trends, and holiday periods can slash your volume by 50% overnight. Your cash flow planning must account for these dramatic swings.

  • Summer months: 30-50% volume drop during vacation season
  • Remote work days: Fridays often see 60% fewer orders
  • Holiday periods: Many offices close for entire weeks
  • Illness waves: COVID/flu outbreaks can halve volume for weeks

Contract types and pricing

Corporate clients push for fixed pricing and guaranteed delivery schedules. Each contract type shifts your risk profile and pricing power in different ways.

💡 Three pricing models:

  • Per unit: €12.50 per lunch, flexible volume
  • Subscription: €11.00 per lunch with minimum 20/day
  • Catering contract: €10.50 per lunch with annual contract 50/day

⚠️ Watch out for contract risks:

Fixed-price contracts make you absorb all ingredient cost inflation. Build in escalation clauses for cost increases above 10% or cap contract terms at 12 months maximum.

Break-even analysis

Office lunch break-even calculations work differently than regular delivery math. Your fixed costs run higher, but you're also capturing better margins per unit sold.

💡 Break-even calculation:

Fixed costs per day: €170
Margin per lunch: €4.50 (€12.50 - €8.00)

Break-even volume = Fixed costs / Margin per lunch

€170 / €4.50 = 38 lunches per day

How do you calculate feasibility? (step by step)

1

Calculate your complete cost price per lunch

Add up: ingredients, special packaging (€0.60-1.00), labor, delivery costs and your share of daily fixed costs (heat retention equipment, larger vehicle). Don't forget the 9% VAT on the selling price.

2

Determine your minimum selling price for 35% margin

Use the formula: Cost price / (1 - 0.35) = Minimum selling price excl. VAT. Multiply by 1.09 for the price including VAT. This is your absolute minimum for profitability.

3

Calculate your break-even volume per day

Divide your total daily fixed costs by your margin per lunch. This gives you the minimum number of lunches you need to sell per day to break even.

✨ Pro tip

Run a 3-week test with 25 lunches daily to one office before investing in specialized equipment. Track actual coordination time, temperature retention, and client feedback - real costs typically exceed estimates by 30%.

Frequently asked questions

What's a realistic margin for office lunch delivery?

Target 35% gross profit minimum. Office lunch carries higher fixed costs and customer concentration risks than regular delivery. Volume contracts can drop you to 30%, but don't go lower or you'll struggle with cash flow.

How many lunches do I need daily to break even?

Break-even typically hits at 35-50 lunches daily, depending on your specific cost structure. Real profitability starts around 80-100 lunches per day. Build volume gradually rather than overcommitting early.

How much extra does heat retention packaging cost?

Heat retention packaging runs €0.60-1.00 per lunch versus €0.15-0.25 for standard containers. That's triple the cost - a major expense line that must be built into your pricing calculations.

How do I handle seasonal volume drops in office lunch?

Plan for 30-50% volume drops during summer vacation periods. Build cash reserves during peak months or develop alternative channels like schools or healthcare facilities to fill summer gaps.

Should I sign fixed-price contracts with offices?

Fixed contracts provide volume certainty but create cost inflation risk. Limit terms to 12 months maximum and include escalation clauses for ingredient cost increases above 10%. Start with flexible arrangements first.

What happens if food temperature drops during delivery?

Corporate clients expect food at 65°C minimum upon arrival. Temperature complaints can kill contracts instantly. Factor in high-grade thermal bags and heating pads - cheap solutions will destroy your reputation fast.
