About NetTake

A small site that answers one question well: after every fee, what do you actually keep?

How fees are sourced

Every figure on this site comes from the marketplace's own published schedule, retrieved on the date shown on the page, with the retrieved copy archived in the repository. Not from a blog post, not from a seller forum, not from a 3PL's marketing page, not from a competitor's calculator, and not from an AI summary. Today there are 4 source documents behind the site, read between November 7, 2026 and November 14, 2026.

• Amazon referral fees and selling plan prices — read November 7, 2026 from a public page.
• Amazon fulfilment, storage, inbound placement, aged and low inventory, returns — read November 8, 2026 from a Seller Central login.
• Amazon removal, disposal and liquidation order fees — read November 13, 2026 from a Seller Central login. The article is headed 2026 and its newest dated rule is 2026-01-15. Amazon's later "2027 US FBA fulfillment fee changes" article, also read here, carries no removal table.
• TikTok Shop referral fees by category and the refund administration fee — read November 14, 2026 from a public page. The category table is headed 2024 and its newest dated rule is 2025-05-15.

The marketplaces are not the same shape, so the module that holds the figures is not either: fees.js carries Amazon's tables, src/tiktok-fees.js carries TikTok Shop's, and each keeps its own source and date next to the numbers rather than in a note elsewhere.

Each fee line carries its own record: the exact page it came from, whether that page is public or behind a login, and the date it was read. On Amazon, referral fees are on a public page and the fulfillment, storage, inbound, low-inventory, aged-inventory and returns tables are behind a Seller Central login; on TikTok Shop the rate table is public. The site says which is which on every row rather than implying that everything can be checked without logging in — or, worse, that everything was read today.

Where a marketplace's own page carries a caveat, the caveat travels with the number. TikTok Shop's category table is headed "Referral Fees in 2024" and its newest dated rule is May 15, 2025, so the TikTok calculator says so in a warning on the page and the home page repeats it in this list. A rate that we cannot show is current is described as the last published figure we could verify, not as today's.

Where a figure could not be read off the official schedule, it is stored as null and the row says needs input or not charged. It is never estimated, rounded to a "typical" value, or replaced with a range midpoint. Amazon publishes inbound placement as a range; where a source publishes a range, this site shows both ends and tells you which end it used.

Rates are also dated. Amazon publishes fulfillment fees in windows, so the fulfilment calculator looks up whichever window covers the day you load the page and prints its name and dates above the result. Past the end of the last verified window the calculator refuses to print a number at all — and where a rule expires, as the returns fee exemption does on 15 January 2027, it says what happens either side of the date.

The reason for the strictness is that the alternative is invisible. A wrong referral percentage and a right one look identical on a page. The only thing a reader can check is whether a source and a date are shown — so that is what this site shows.

How often fees are re-checked

• Monthly, 10 minutes: skim the fee announcements of every marketplace we cover. Both have changed fees mid-year — Amazon more than once, and TikTok Shop moved to its 6% referral rate on 1 April 2024 and restated its refund administration fee on 15 May 2025 — so the calendar alone is not enough.
• Quarterly, 90 minutes: full pass over the fee module against the official schedule, then FEES_AS_OF moves forward and every page picks up the new date at build time.
• Automatically: each table has an end date. When one passes, the build fails and names the document that needs re-reading, instead of quietly serving last year's rates.

The Amazon verification date is November 8, 2026, and each marketplace's date is listed above and printed on its own pages. It is a claim about our diligence, not about anyone's prices.

What this site is not

• Not affiliated with, endorsed by, or operated by any marketplace whose fees it calculates. Amazon, Fulfillment by Amazon and related marks belong to Amazon.com, Inc.; every marketplace name on the site is used descriptively and belongs to its owner.
• Not financial or tax advice. It is arithmetic on published rates.
• Not an account system. There is nothing to sign up for and no email capture.

How the site is built

Static HTML, one hand-written stylesheet, a small amount of vanilla JavaScript for the calculator. No client-side framework, no web fonts, no third-party scripts. The fee tables and the verification date are rendered into the HTML at build time, so they are present before any script runs — which matters both for readers and for anyone indexing the page.

Source of the verified figures: sell.amazon.com/pricing.
