Rate card verification status
What in this calculator is verified vs transcribed from secondary sources
- verifiedReferral rates (Beauty/Health 8% ≤ $10 else 15%; Home & Kitchen and Sports & Outdoors flat 15%; $0.30 minimum per item), the three 2026 price bands (<$10 Low-Price FBA / $10–50 / >$50), Small standard ≤ 2 oz at $2.43 / $3.32 / $3.58, Large standard 12–16 oz at $4.60 ($10–50 band), dimensional weight = L×W×H ÷ 139, standard size-tier limits, and the 3.5% fuel & logistics surcharge applied on top of FBA fees since April 17, 2026 (rate cards exclude it; it is shown as its own segment here).
- secondaryThe remaining weight-step rates are transcribed from the published 2026 rate card as mirrored by AMZ Prep, Sellerise and Seller Snap (all three transcriptions agree) but have not been re-checked against Seller Central directly. Bulky and extra-large tier boundaries and rates use a simplified per-pound model.
- scopeNot modeled: monthly + aged storage fees, the low-inventory-level fee, inbound placement fees, returns processing, and holiday peak surcharges. Referral and FBA fee minimums apply; treat results as pre-launch screening, not accounting.
