Amazon seller-fee source-state
Amazon seller-fee source-state status for Margin Ruler: verified notice facts, modeled planning estimates, exclusions, and pending fee-table capture.
Amazon FBA is active. Other marketplace modules stay marked as planned until audited.
2026 Amazon seller-fee changes. This page renders the portfolio source-state register for Amazon US seller-fee families used by Margin Ruler. The register separates primary-verified facts, secondary-basis planning estimates, explicit exclusions, and guidance-only claims.
- Amazon's 2026 seller-fee notice reported an average FBA fee increase of about $0.08 per unit sold.
- The same notice stated that no new FBA fee types are being introduced in 2026.
- The notice stated the 2026 changes are effective January 15, 2026 unless otherwise noted.
A fuel/logistics surcharge has been reported by third parties, but the cited Seller Central detail page was not readable in this environment and the primary 2026 fee notice did not confirm it. Margin Ruler treats it as guidance only until confirmed from a primary Seller Central source.
The per-tier 2026 fulfillment, referral, and storage tables are pending logged-in Seller Central capture. Until then, affected calculator output remains a planning estimate rather than an authoritative Seller Central reconciliation.
