03 / faqHow accurate is this calculator?
Fee tables are sourced from Amazon's 2026 published US schedule (last verified Jan 15, 2026 against Amazon's own announcement, then cross-checked against FeeYield's June 27 update). Actual Amazon invoices can differ by ±2% due to dimensional-weight rounding, aged-inventory surcharges, removals, and category-specific overrides. For final pricing decisions, always check your own Amazon statement.
Why is my number different from Amazon's official Revenue Calculator?
Amazon's tool uses a simplified model that doesn't always include the Inbound Placement Fee or Low-Inventory Fee. Those two together can be $0.30–$0.70 per unit for low-stock standard-size items. Our calculator includes them by default.
Is my financial data sent anywhere?
No. All calculations happen in your browser. We do not log inputs, do not use analytics that fingerprint you, and do not store cookies beyond what's strictly necessary to serve the page.
Do I need an Amazon Seller account?
No. Open the page and start calculating. No Amazon login, no FBATools account, no email.
