Reusable packaging creates a complex web of upfront investments, deposits, and variable costs that can make or break your delivery margins. Unlike disposables with their straightforward per-order pricing, sustainable containers demand a completely different financial approach. You're essentially running two businesses: food delivery and container logistics.
The cost structure of reusable packaging
Reusable packaging flips traditional cost accounting on its head. Instead of simple per-unit expenses, you're managing cycles, return rates, and depreciation. The real challenge isn't buying containers—it's predicting how many times each one comes back.
💡 Example cost structure:
Reusable containers for 1000 orders per month:
- Purchase 200 reusable containers: €1,200
- Deposit per container: €2.00
- Cleaning per container: €0.30
- Loss/damage: 5% per month
Cost per order after 6 months: €0.65
Calculating actual packaging costs
Forget everything you know about packaging math. With reusables, you're calculating costs per cycle, not per unit. Each container needs to complete 15-25 trips to justify its existence.
Formula for cost per order:
(Purchase price / Number of cycles) + Cleaning costs + Loss percentage
💡 Calculation example:
Reusable container costing €6.00:
- Purchase price per cycle: €6.00 / 20 cycles = €0.30
- Cleaning per use: €0.30
- Loss (5% per cycle): €0.30 × 0.05 = €0.015
Total cost per order: €0.615
Comparison with disposable packaging
After managing kitchen operations for nearly a decade, I've seen countless operators underestimate the true cost of disposables. You're not just buying a container—you're paying for lids, cutlery, napkins, and bags.
- Disposable packaging: €0.45 - €0.80 per order
- Reusable packaging: €0.60 - €0.90 per order (first year)
- Reusable packaging: €0.30 - €0.50 per order (from year 2 onwards)
⚠️ Note:
Don't forget the deposit's impact on cash flow. You'll advance €2.00 per container, getting it back only when returned. That's €2,000 in working capital for 1000 monthly orders.
Impact on your food cost and margin
Every euro saved on packaging drops straight to your bottom line. But here's what most operators miss: packaging costs directly affect your food cost percentage, not just your margins.
💡 Impact on annual basis:
With 1000 orders per month and €0.20 savings per order:
- Savings per month: €200
- Savings per year: €2,400
- ROI on €1,200 investment: 200%
Break-even after 6 months
Return rate and loss costs
Containers disappear. Period. Customers forget them, toss them, or they break during washing. Plan for 10-20% loss in year one, then 5-10% ongoing.
Build this reality into your calculations:
Loss costs = Purchase price × Loss percentage × Number of containers issued
Delivery platforms and reusable packaging
Here's where things get expensive fast. Thuisbezorgd and Uber Eats typically charge commission on your total order value, including that €2.00 deposit. Suddenly your platform fees jump by €0.30-€0.60 per order.
- Platform commission on deposit: €0.30 - €0.60 per order
- Extra administration for deposit handling
- Possible lower conversion due to extra checkout step
⚠️ Note:
Platform policies on deposits vary wildly. Some charge commission, others don't. This single factor can make or break your entire sustainable packaging strategy.
Registration in food cost systems
Set up reusable packaging as an ingredient with a cost per use in your food cost system. This immediately shows the impact on your food cost per dish and keeps your calculations honest.
Treat packaging costs as variable expenses per portion—they'll automatically factor into your margin calculations. But deposits? That's working capital, not a direct cost.
How do you calculate the margin on sustainable delivery? (step by step)
Calculate costs per cycle
Divide the purchase price by the number of times a container is used (15-25x). Add cleaning costs (€0.25-€0.35) and loss percentage (5-10%).
Compare with disposable costs
Add up all disposable packaging: container, lid, cutlery, napkin, bag. Compare this with your cost per cycle for reusable packaging to see where you break even.
Factor in platform costs
Delivery platforms often charge commission on deposits. With €2.00 deposit and 20% commission, you pay €0.40 extra per order. Add this to your packaging costs.
Plan your working capital
Deposits are prepaid money. With 1000 orders per month, you're putting forward €2,000. Plan this in your cash flow, as you only get it back when containers are returned.
Monitor return rate
Keep track of how many containers come back. Below 80% return, reusable packaging often becomes more expensive than disposables. Communicate clearly with customers about returns.
✨ Pro tip
Test with just 50 containers for your first 30 days to nail down your actual return rate before committing to larger inventory. Most operators overestimate returns by 15-20% in their initial projections.

Frequently asked questions
When is reusable packaging cheaper than disposable?
Usually after 6-12 months, if your return rate stays above 80% and you're doing more than 500 orders monthly. Break-even depends entirely on your current disposable costs and how many cycles each container completes.
How do I calculate platform commission on deposits?
Most platforms charge commission on total order value including deposits. With a €2.00 deposit and 20% commission, you're paying an extra €0.40 per order to the platform. Always verify this with your specific platform first.
What if customers don't return containers?
Plan for 10-20% loss in the first year, dropping to 5-10% once customers adapt. Build this into your cost price using: purchase price × loss percentage. Below 80% return rates, the economics usually fall apart.
How do I register this in my cost price calculation?
Include cost per cycle as packaging costs in your food cost calculations. Deposits are working capital—not direct costs—so don't factor them into your food cost percentage. Keep these two categories completely separate.
