How Amazon FBA Fees Work in 2026

Selling on Amazon FBA means Amazon handles storage, packing, and shipping for you โ€” but it comes at a cost. Understanding these fees across different marketplaces is essential to maintaining healthy profit margins. This free FBA calculator supports all 21 Amazon marketplaces worldwide, with built-in currency conversion so you can see your true profit in your home currency.

Referral Fees

Amazon charges a referral fee on every sale, calculated as a percentage of the total selling price. The percentage varies by category โ€” most categories charge 15%, but electronics charge 8%, jewellery can go up to 20%, and some categories have tiered rates that change based on the item price. There's also a minimum referral fee per item that varies by marketplace.

FBA Fulfillment Fees

This is what Amazon charges to pick, pack, and ship your product to the customer. The fee depends on two factors: the product's size tier (determined by dimensions and weight) and the marketplace. European marketplaces follow a unified rate card with per-country fees, while the US, Japan, Australia, and other regions each have their own fee structures. In 2026, most European fees include a 1.5% fuel and power surcharge.

Monthly Storage Fees

Amazon charges monthly storage fees based on the volume your inventory occupies in their fulfilment centres. Rates vary significantly across marketplaces โ€” from cubic feet pricing in the UK and US to cubic metre pricing across the EU. Rates are typically lower from January to September and spike during Q4 peak season (Octoberโ€“December).

Currency Conversion for International Sellers

If you sell across multiple Amazon marketplaces, your costs and revenue may be in different currencies. Our calculator includes built-in currency conversion โ€” select your home currency to see your profit, fees, and revenue converted automatically. Exchange rates are updated periodically and should be used as estimates for planning purposes.

Frequently Asked Questions

Is this FBA calculator really free?
Yes, completely free. No sign-up, no email required, no usage limits. Use it as much as you need to price your products profitably across any Amazon marketplace.
Which Amazon marketplaces are supported?
All 21 Amazon marketplaces worldwide: UK, Germany, France, Italy, Spain, Netherlands, Belgium, Poland, Sweden, Turkey (Europe); US, Canada, Mexico (North America); Brazil (South America); Japan, Australia, India, Singapore (Asia Pacific); UAE, Saudi Arabia, Egypt (Middle East). Fees for major marketplaces use official 2026 rate cards; smaller marketplaces use carefully estimated rates.
How does the currency conversion work?
Select your home currency from the "Your Currency" dropdown. All fees are calculated in the marketplace's local currency, then your profit, revenue, and total fees are converted to your chosen currency using periodically updated exchange rates. This lets a UK seller, for example, see their US marketplace profit in GBP.
How accurate are the fee calculations?
Major marketplaces (UK, US, Germany, France, Italy, Spain, Japan, Australia, UAE, Saudi Arabia) use official 2026 Amazon fee schedules. Smaller marketplaces use carefully estimated rates. Amazon occasionally updates fees mid-year, so we recommend cross-checking with Amazon Seller Central for the very latest rates.
Does this calculator include VAT or sales tax?
Yes โ€” under Optional Fields, you can toggle tax on. The label and rate automatically adjust to the marketplace: VAT for European markets (19โ€“25%), GST for Australia (10%) and Canada (5%), IVA for Mexico (16%), and so on. US sellers don't have a federal equivalent in this context.
