Amazon.com is the world's largest e-commerce marketplace, with millions of sellers competing across every category. We're building a full suite of free FBA tools for US sellers — profit calculators, fee breakdowns, ACoS calculators, and more, all calibrated around amazon.com's current fee schedule and priced in USD.
Our US tool suite will include an FBA profit calculator using the current amazon.com referral fee schedule (8–15% by category) and FBA fulfilment fees by size tier, an ACoS calculator for PPC break-even analysis, a restock calculator to prevent stockouts and overstocking, a full fee breakdown tool by size tier and category, and a wholesale ROI calculator for bulk sourcing decisions. Every tool will update in real time as you type and require no account or login.
Amazon.com updates its fee schedule every year — usually in January or February — and often makes additional mid-year changes. Most free FBA calculators online use outdated fee data, which means your profit calculations are wrong before you've even started. We commit to updating our fee schedules within 24 hours of any Amazon change. Our US FBA tools are in active development. Check back soon or bookmark this page to be among the first to use them when they launch.
