📦 E-Commerce Fulfillment Cost Per Order Calculator
How to Use This Calculator
- Enter all per-order cost components — pick cost, pack cost, and packaging materials.
- Include returns provision — return rate × return processing cost — this must be in your per-order cost model.
- Allocate overhead — monthly warehouse overhead ÷ monthly orders = overhead per order. Often forgotten in e-commerce margin calculations.
Worked Example
5,000 orders/month, 1.8 units, $0.90 pick, $1.20 pack, $1.45 materials, $8.50 shipping, 12% returns at $8.50, $18K overhead.
- Pick: $1.62
- Pack + materials: $2.65
- Returns provision: $1.02
- Overhead: $3.60
- Fulfillment CPO: $8.89
- Total with shipping: $17.39
At $17.39/order total cost, an order with $25 revenue and 40% gross product margin ($10 gross margin) yields $10 − $17.39 = -$7.39 per order loss. Many e-commerce businesses discover this only after scaling — model it first.
Frequently Asked Questions
Your average shipping cost + the return rate cost should both be priced into your product. If shipping costs $8.50 and 12% of orders are returned ($1.02 provision), that's $9.52 per order that needs to come from product margin. "Free shipping" is never free — it's just priced differently.
Increase units per order (bundle promotions, order minimums for free shipping). Reduce return rate (better descriptions, photos, sizing). Automate pick/pack (scan-verify, batch picking). Negotiate packaging material costs on volume. Reduce warehouse overhead per order by increasing throughput vs fixed costs.
