Amazon FBA Fees Calculator (2026 Rates)

Every Amazon FBA fee, in order

An FBA sale pays up to four fees, and the ones that sink products are never the headline rate. In order of size for most sellers: the referral fee (Amazon's commission), the FBA fulfillment fee (pick, pack, ship), your selling plan, and the slow drips (storage, inbound placement, closing fees). This Amazon FBA fees calculator computes the first and third exactly and takes the second as your verified input — because that's the only honest way to do it.

Referral fee: the category table decides

Most categories charge 15% of the total sales price (item + shipping + gift wrap), $0.30 minimum — but the 37-row table matters: 8% on computers and consumer electronics, 12% on automotive, tiered jumps in clothing (5%→17%) and jewelry (20%→5%), 45% on Amazon device accessories. Select your exact category above; the rate table below shows every row Amazon publishes, verified 2026-10-14. And because the minimum fee exists, sub-$3 items pay an outsized rate: at $2.00 the $0.30 minimum is already 15% before the percentage even applies.

Fulfillment fee: the number you paste

Amazon only shows current FBA size-tier rates inside Seller Central, so any site that auto-fills them is guessing with stale data. Open your product's fee preview in Seller Central, copy the per-unit fulfillment fee, and paste it into the field above — everything else in the result stays exact. It's one extra lookup for numbers you can actually source.

Plan math: the 40-sale line

Individual ($0.99/item) versus Professional ($39.99/month) is a fixed crossover: 40 sales a month. Below that, Individual is cheaper; above, Professional — and the professional-only tools (ads, buy box, bulk listings) are what most sellers actually need anyway. Enter monthly sales in advanced inputs to see the plan amortized per order — the tier selector runs both schedules side by side, so the 40-sale line stops being trivia and becomes your actual answer.

How to calculate ROI on an FBA product

ROI = (net payout − product cost − inbound shipping) ÷ product cost × 100. Get net payout from the calculator, subtract your landed cost, divide by it. Most experienced FBA sellers won't source under 30% ROI because returns, storage, and price erosion eat the margin — the fee math is the only part you can pin down exactly before buying, so pin it. Then re-run it quarterly: Amazon reprices the fee card every winter, and last year's winner can go negative without a single change on your side.

Worked example: sourcing a $35 kitchen gadget

You're evaluating a gadget that sells at $35 in home & kitchen (15% referral). Landed cost is $9/unit, inbound freight $1.10, and Seller Central shows a $4.87 fulfillment fee for its size tier. Run it above: referral $5.25 + fulfillment $4.87 = $10.12 in Amazon fees, net payout $24.88. ROI = ($24.88 − $9.00 − $1.10) ÷ $9.00 = 164% — comfortably sourceable. The same gadget with a $7.50 fulfillment tier instead drops ROI to 135%; the entire sourcing decision swings on a fee Amazon only shows you after login, which is why the paste-it-in approach exists.

Amazon FBA fees vs other channels

At 15% referral plus fulfillment, Amazon is rarely the cheapest channel per sale — eBay and Walmart usually undercut it on identical items. What it sells is conversion and logistics at scale. Price the same item everywhere in the all-platform comparator and let the fee math set your floor — then check whether each channel's audience can actually move your volume target at that price before committing inventory.
