Know what Amazon returns
actually cost you.
Amazon's FBA high-return-rate fee has been in effect since June 1, 2024: once your return rate crosses your category's threshold, every excess return is charged. Estimate your monthly exposure and annualized loss under the updated 2026 US rate card — before the charge shows up on your settlement report.
No sign-up required. Rates reflect Amazon's published 2026 US rate card (amazon.com marketplace).

Calculation assumptions
- Fee = chargeable units × rate-card fee for your size tier, where chargeable units = (return rate − category threshold) × units shipped, rounded up.
- Apparel & Shoes: no threshold; all returns are charged from the apparel rate card.
- Exemptions not modeled: fewer than 25 units shipped/month, FBA New Selection (first 20 returns waived), returns caused by Amazon's own errors.
- All rates and thresholds apply to the Amazon US marketplace (amazon.com) only. The fee has applied since June 1, 2024; figures reflect the rate card updated effective January 2026.
- This is the returns processing fee only. It excludes refunds, sunk outbound fulfillment fees, refund admin fees, and unsellable inventory — your true cost per return is typically 3–5× the processing fee.
- Amazon measures return rate on a 3-month rolling window; recent months are provisional.
