How this calculator works: This estimator uses Amazon's published 2026 referral fee rates by category and approximates FBA fulfillment fees based on weight and dimensions. Real Amazon fees have many tier edge cases (oversize bands, peak fees, apparel categorization, etc.) so your actual fees may differ by 5-10%. For pinpoint accuracy on your full catalog, connect SellerVault via SP-API and we'll pull your real fee data directly from Amazon.
