How Much Does the Platform Really Take in Commission: The Math on 1 Million in Annual Sales
Break "platform commission" into five parts—commission, payment processing fees, advertising, warehousing and logistics, and return losses—and walk you through the math on 1 million in annual sales, then compare it with the cost structure of an independent store.
Sellers say "the platform takes 5%," but that usually covers only one of five cost components. What really weighs on profit is the combined effect of the five items below.
1. Breaking "commission" into five parts
| Cost item | Typical range | Billing method | Does the share change with scale? |
|---|---|---|---|
| Platform commission | 2% – 8% | Based on transaction value | Basically fixed |
| Payment processing fee | 1% – 3% | Based on transaction value | Basically fixed |
| On-platform advertising | 5% – 20% | Per click / bidding | Higher with more competition |
| Warehousing and logistics | 3% – 10% | Per item / per volume | Diluted with scale |
| Returns and shrinkage | 1% – 5% | Per order | Varies greatly by category |
Adding up the midpoints: 12% to 46%. This is why many sellers feel that "order volume is rising but profit isn't"—the increase is eaten up by advertising and returns.
2. The math on 1 million in annual sales
Estimated at industry median levels (excluding procurement cost):
| Item | Percentage | Amount |
|---|---|---|
| Transaction value | — | 1,000,000 |
| Platform commission | 5% | -50,000 |
| Payment processing fee | 2% | -20,000 |
| On-platform advertising | 12% | -120,000 |
| Warehousing and logistics | 6% | -60,000 |
| Returns and shrinkage | 3% | -30,000 |
| Total taken | 28% | -280,000 |
In other words, 280,000 out of 1 million never reaches your pocket, and that's before procurement cost, labor, and taxes.
3. What the cost structure of an independent store looks like
| Item | Independent store | Notes |
|---|---|---|
| Transaction commission | 0 | No platform percentage cut |
| Payment processing fee | 1% – 3% | Paid only to the payment channel; unavoidable |
| Customer acquisition cost | Variable, but controllable | You decide how much to spend; stop spending when you stop |
| System cost | Fixed annual fee | Does not rise with transaction value |
| Traffic ownership | Yours | Customer lists and behavioral data can be exported and reused |
The key difference isn't "cheaper"—it's the shape of the cost: the platform takes a percentage (the more you sell, the more it takes), while an independent store has fixed costs + self-directed ad spend (the more you sell, the lower the system cost share).
4. Not every business should move
To be honest, staying on the platform is more cost-effective in these cases:
- Still in the product-testing stage—the platform brings its own traffic; an independent store takes a long time to build from zero.
- Extremely low average order value—a few dollars per item makes customer acquisition cost hard to amortize on an independent store.
- No content/advertising capability at all—an independent store doesn't provide traffic; you have to find it yourself.
Independent stores are best suited for sellers who already have stable sales, are seeing commissions and ad costs eat into profit, and want to build customers into their own assets.
Conclusion
To decide whether to move, you only need to calculate one number: is the money the platform took from you as a percentage last year enough to cover several sets of fixed costs? With 1 million in annual sales and 280,000 taken, the answer is obvious.
