Why Shipping Cost Per Unit Matters
Shipping cost is one of the most underestimated expenses in e-commerce. Many sellers set prices based on product cost alone and treat shipping as an afterthought. At scale, shipping expenses can consume 8-20% of revenue - knowing your exact shipping cost per unit is essential for pricing, profitability, and deciding whether to offer free shipping.
When Does Free Shipping Make Sense?
Free shipping makes sense when your gross margin on the order exceeds the shipping cost. A 40% gross margin on a $50 order gives you $20 in margin - if shipping costs $8, free shipping still leaves you $12 in gross profit. Setting a free shipping minimum (e.g. "free shipping on orders over $50") filters for orders where the math works.
What is a Healthy Shipping Cost Ratio?
- Under 8%: Excellent - shipping is not a major margin concern
- 8-15%: Acceptable for most e-commerce categories
- 15-25%: High - consider adjusting pricing or reducing package size/weight
- Over 25%: Critical - shipping is significantly impacting profitability
