Many sellers calculate dropshipping counting only "handling fee per order." But the real cost hides in the lines the quote didn't write.
Easily-missed costs
- Inbound fee: by box or by piece, charged on bulk inbound
- Storage fee: monthly or by volume, slow-moving inventory quietly eats money
- Return handling fee: inspection and re-shelving all need labor
- Value-added operation fee: labeling, relabeling, consolidation billed separately
- Last-mile freight: often a much larger share than handling fee
How to calculate so you don't lose
Spread one order's "head freight + inbound + storage allocation + handling + last-mile + possible returns" all out, then compare with selling price and platform commission — that's real gross margin.
Counting only handling fee is seeing just the tip of the iceberg.
Build a per-SKU cost table and fill in each item above. Once clear, raise price where needed, switch warehouse where needed — decisions have a basis.
