Here is a realistic month for a private-label FBA seller doing $10,000 in ordered product sales, so you can sanity-check your own effective take rate:
| Line | Amount | % of gross sales |
|---|
| Product sales | +$10,000 | 100% |
| Customer refunds (8% of sales) | −$800 | 8% |
| Referral fees (15% category rate) | −$1,500 | 15% |
| FBA fulfillment fees ($3.50 avg × ~630 units) | −$2,200 | 22% |
| Monthly + long-term storage fees | −$150 | 1.5% |
| Sponsored Products spend (deducted from payout) | −$1,200 | 12% |
| FBA inventory reimbursements | +$90 | — |
| Net transferred | ≈ $4,240 | ≈ 42% |
Roughly 58% of gross never reaches the bank — before a single dollar of product cost. That is not a scandal; it is the normal FBA cost structure. The number to monitor is the trend: if your effective deduction rate creeps from 55% to 62% with no strategy change, something specific (fee tier bump, return-rate rise, ad efficiency decay) is eating margin, and this report is where it shows up first.
Note that advertising only appears in the payout if you pay for ads from your sales proceeds — many sellers charge ads to a credit card, in which case ad spend never touches the settlement and must be added back separately when judging profitability.
