Every calculation runs in your browser. The figures you type are never sent to a server and are never stored.

This calculator needs JavaScript. The maths runs in your browser — that is why your figures never leave your device — so it cannot work with JavaScript turned off. The rest of the page (formulas, worked examples and explanations) reads exactly the same.

Your results will appear here

You need the selling price, the product cost and the fulfillment fee.

Check the marketplace in the settings bar.
Enter price, cost and fulfillment fee.
Pick your selling plan and add the remaining costs.

Results are estimates based on the information you enter. Fees, taxes and platform terms can change: always check the figure that matters to you against your invoice or the official platform. They do not replace your real invoices, your official accounts or professional tax, financial or legal advice.

This tool is independent and is not affiliated with, sponsored by or endorsed by Amazon. The Amazon fulfillment fee depends on the category, dimensions, weight, country, season and fulfillment programme. It cannot be estimated reliably without the product data: enter it manually from Seller Central or from the marketplace's official revenue calculator.

Active marketplace: Amazon.com

Amazon FBA has a more branching cost structure than any other common sales channel, and much of it depends on the specific product and marketplace: two items at the same price can carry very different fulfillment fees over a few centimetres or a few grams, and the same product faces selling plans priced differently in the United States, the United Kingdom, Canada or Australia.

The seven layers of cost in FBA

Selling plan. Individual per unit or Professional per month, priced differently per marketplace.
Referral fee. A percentage of the price, by category.
Fulfillment fee. The logistics cost per unit shipped.
Storage. Monthly, by volume and season.
Inbound shipping and prep. Getting the goods to Amazon and making them compliant.
Returns. With their handling costs and unsellable stock.
Advertising. Amazon Ads, which in practice is close to mandatory.

Only the first two and the last are percentages or amounts you can know without more data. The other four depend on your product and your operation.

Individual or Professional plan

The prices for both plans are in the comparison table above. The arithmetic is direct: the indifference point sits where the monthly subscription equals the per-unit amount times your sales. At 39 a month and 0.99 per unit that is around 40 monthly units; at 25 and 0.75, about 33; at 49.95 and 0.99, about 50.

What changes the calculation is that the Professional plan unlocks features the Individual one does not have, advertising among them, so in practice the comparison is not only about price.

For per-unit maths, what matters is spreading the subscription: 39 across 100 units is 0.39 per unit; across 10 units, 3.90. On thin-margin, slow-moving products that difference decides viability.

Frequently asked questions

Why do I have to look up the fulfillment fee in Seller Central?

Because it depends on the category, dimensions, weight, country, season and fulfillment programme of your specific product. A generic estimate would produce a result that looks precise and is not, and at margins like the example's an error of 1 in that fee changes the conclusion.

Is the referral fee always 15%?

No. The 15% is only an editable starting point. Amazon states most referral fees fall between 8% and 15%, with outliers from 5% to 45% by category and minimum amounts in some.

Do the plans cost the same in every marketplace?

No, and that is one reason for the comparison table. The Professional monthly fee and the Individual per-unit amount differ in each marketplace, and some are quoted excluding tax. Pick your market in the calculator and the right values load.

When is the Individual plan better for me?

On volume alone, when you sell fewer monthly units than the monthly fee divided by the per-unit amount. But the Professional plan unlocks features the Individual one lacks, advertising among them, so if you depend on Amazon Ads the comparison stops being only about cost.

How do I allocate storage across units?

Divide the month's storage cost by the units sold that month. If the product turns slowly, cost per unit sold rises: that is the right way for an overstock penalty to show up in the numbers.

Should I include advertising in the profitability calculation?

Yes, if you depend on it to sell. A product that is only profitable without advertising and does not sell without advertising is not profitable.
