Only ratios, shares, rates and index values are published. Attribute every figure to the Nova first-party panel and link https://www.novadata.io/resources/state-of-amazon/methodology. Every statement below carries its own measurement period and basis. ### 35.1% | amazon-take-rate Amazon's total take of seller sales reached 35.1% in the year to August 2026, up 31 basis points year on year, measured on a fixed panel of several hundred Amazon sellers. Total take stacks referral commission, fulfilment, storage, inbound placement and the other Amazon-charged lines against sales. Just over a third of every pound or dollar of sales leaves before cost of goods. Period: September 2024 to August 2026. Basis: Sum of Amazon-charged fees divided by sales, aggregated across the panel, two rolling twelve-month windows compared.. As of: 2026-09-09. ### 13.8% | referral-commission-flat Referral commission held at 13.8% of sales across both years to August 2026 on a fixed panel of several hundred Amazon sellers, unchanged year on year. The entire increase in Amazon's take came from logistics, not from the headline commission rate. Watching the commission percentage alone would have shown a flat year. Period: September 2024 to August 2026. Basis: Referral fees divided by sales, aggregated across the panel, two rolling twelve-month windows compared.. As of: 2026-09-09. ### 19.6% | fba-fulfilment-share FBA fulfilment fees rose from 19.3% to 19.6% of sales in the year to August 2026 on a fixed panel of several hundred Amazon sellers. Fulfilment is the bulk of the increase in Amazon's total take. On a catalogue with thin margins, three tenths of a point of sales is the difference between a profitable SKU and a break-even one. Period: September 2024 to August 2026. Basis: FBA fulfilment fees divided by sales, aggregated across the panel, two rolling twelve-month windows compared.. As of: 2026-09-09. ### +11% | inbound-placement-growth The FBA inbound placement fee grew 11% year on year as a share of sales in the year to August 2026 on a fixed panel of several hundred Amazon sellers. It is the fastest-rising line in the fee ledger. How you split and route shipments into the network now has a measurable effect on unit economics. Period: September 2024 to August 2026. Basis: Inbound placement fees divided by sales, aggregated across the panel, year on year change of that ratio.. As of: 2026-09-09. ### 1.36% to 2.84% | storage-seasonality FBA storage costs sellers 1.36% of sales in February and 2.84% in November on a fixed panel of several hundred Amazon sellers, measured over the twelve months to August 2026. An annual average understates Q4 storage by more than half. Budget storage by month, not as a single yearly percentage. Period: September 2025 to August 2026. Basis: Monthly storage fees divided by monthly sales, aggregated across the panel, over the single twelve-month window September 2025 to August 2026.. As of: 2026-09-09. ### 24.3% | cogs-share Cost of goods ran at 24.3% of sales in the year to August 2026 on a fixed panel of several hundred Amazon sellers, down 38 basis points year on year. Landed product cost improved slightly. That gain was smaller than the rise in Amazon's take over the same period. Period: September 2024 to August 2026. Basis: Seller-entered cost of goods divided by sales, aggregated across the panel, two rolling twelve-month windows compared.. As of: 2026-09-09. ### 2.54% | discounting-down Promotional discounting fell to 2.54% of sales in the year to August 2026 on a fixed panel of several hundred Amazon sellers, down 14% year on year. Sellers competed less on price than the year before. Price cuts were not the lever used to defend volume. Period: September 2024 to August 2026. Basis: Promotional discount value divided by sales, aggregated across the panel, two rolling twelve-month windows compared. Coupons are charged as a separate fee line and are not included.. As of: 2026-09-09. ### 3.53% | refund-rate-annual The refund rate improved to 3.53% of units in the year to August 2026 on a fixed panel of several hundred Amazon sellers. Measured on units refunded against units sold. The annual figure hides a sharp seasonal swing, so read it alongside the January return wave. Period: September 2024 to August 2026. Basis: Refunded units divided by units sold, aggregated across the panel, two rolling twelve-month windows compared.. As of: 2026-09-09. ### 4.17x vs 4.02x | cyber-monday-beats-black-friday Cyber Monday outsold Black Friday in both 2024 and 2025 on a fixed panel of several hundred Amazon sellers, reaching 4.17 times a normal trading day against 4.02 in 2025. The gap widened in the second year. If you plan stock and ad budget around Black Friday alone, you are underweighting the bigger day. Period: September 2024 to August 2026. Basis: Daily units indexed to the trailing normal trading day, aggregated across the panel, two peak seasons compared.. As of: 2026-09-09. ### -60% | bfcm-cliff Unit volume falls about 60% within 24 hours of Cyber Monday on a fixed panel of several hundred Amazon sellers, in both peak seasons measured. The drop is immediate, not gradual. Inventory that has not sold by Cyber Monday evening is Q1 inventory paying Q4 storage rates. Period: September 2024 to August 2026. Basis: Daily indexed units, day after Cyber Monday against Cyber Monday, aggregated across the panel.. As of: 2026-09-09. ### 1.8x | peak-week-runup The week before Black Friday already runs at roughly 1.8 times a normal trading day on a fixed panel of several hundred Amazon sellers, across both peak seasons measured. The peak is a ten-day event, not two days. Stock has to be receivable and live before the run-up starts, not on the Thursday. Period: September 2024 to August 2026. Basis: Daily indexed units across the seven days before Black Friday, aggregated across the panel.. As of: 2026-09-09. ### 1.15% | peak-day-discounting Sellers discount less on the peak days, at 1.15% of sales on Black Friday against 1.55% to 1.80% during the run-up week, on a fixed panel of several hundred Amazon sellers. Demand does the work on the peak days. The heavier discounting sits in the run-up, where sellers are buying visibility rather than converting ready buyers. Period: September 2024 to August 2026. Basis: Promotional discount value divided by sales, by day, aggregated across the panel. Coupons are charged as a separate fee line and are not included.. As of: 2026-09-09. ### 6.65% | january-return-wave Refunds peak in the first week of January at 6.65% of units on a fixed panel of several hundred Amazon sellers, three and a half times the 1.85% recorded during Black Friday week itself, measured across the winter of 2025 into 2026. Returns do not settle until late February. Peak-season profit is not final until the wave has passed, so hold back cash accordingly. Period: November 2025 to February 2026. Basis: Weekly refunded units divided by units sold, aggregated across the panel, one winter: November 2025 to February 2026.. As of: 2026-09-09. ### under 0.2 | bfcm-shape-stable Aligned on Black Friday, the 2024 and 2025 daily volume curves on a fixed panel of several hundred Amazon sellers never diverge by more than 0.2 index points across fourteen days. The shape of the peak repeats. That makes it plannable: last year's daily curve is a usable forecast for this year's. Period: September 2024 to August 2026. Basis: Daily units indexed to a normal trading day, two peak seasons aligned on Black Friday and compared point by point.. As of: 2026-09-09. ### -18% | prime-day-moved Amazon moved Prime Day from July 2025 to late June 2026 and peak-day volume on a fixed panel of several hundred Amazon sellers fell about 18%. Same sellers, same measurement, different calendar slot. Treat a Prime Day date change as a demand event, not just a diary change. Period: September 2024 to August 2026. Basis: Peak-day indexed units for each Prime Day event, same accounts in both years.. As of: 2026-09-09. ### 4 | four-annual-peaks Amazon sellers on a fixed panel of several hundred Amazon sellers see four annual peaks, not one, across the two years to August 2026. Prime Day, Prime Big Deal Days in October, the Black Friday to Cyber Monday block, and the mid-December shipping deadline. Each needs its own inbound plan. Period: September 2024 to August 2026. Basis: Daily indexed units across the full period, peaks identified where the index sustains a clear step above the trailing baseline.. As of: 2026-09-09. ### mid-2025 | coupon-fee-migration Between June and July 2025 Amazon replaced the flat coupon redemption fee with a performance fee plus a participation fee, visible in the fee ledger of a fixed panel of several hundred Amazon sellers. Any coupon cost comparison spanning mid-2025 compares two different fee schedules. Split your before and after windows at the changeover rather than reading one trend line. Period: September 2024 to August 2026. Basis: Coupon-related fee lines observed month by month across the panel, changeover dated where the fee composition changes.. As of: 2026-09-09. ### 27.3% to 39% | category-take-spread Amazon's total take ranges from 27.3% of sales in Home & Kitchen to 39% in Grocery, measured across the wider panel of Amazon sellers, with no cost of goods requirement over July to August 2026. Where you sell changes what Amazon keeps by nearly twelve points of sales. A margin model built on one category does not transfer to another. Period: July to August 2026. Basis: Amazon-charged fees divided by sales, aggregated by normalised category, July to August 2026 at roughly 70% category coverage.. As of: 2026-09-09. ### 10% to 22.5% | category-referral-vs-fulfilment Across categories the referral commission varies only from 12.8% to 16.5% of sales while FBA fulfilment varies from 10% to 22.5%, so the cost difference between categories is a fulfilment difference, not a commission difference. Category choice is usually discussed in terms of the referral rate. The referral rate is the part that barely moves. Size, weight and how the unit ships are what separate a cheap category from an expensive one. Period: July to August 2026. Basis: Referral fees and FBA fulfilment fees each divided by sales, aggregated by normalised category, July to August 2026 at roughly 70% category coverage.. As of: 2026-09-09. ### 1.76% to 9.87% | category-refund-spread Refund rates range from 1.76% of units in Grocery to 9.87% in Clothing & Accessories, a spread of more than five times, measured over July to August 2026. Returns are a category property before they are a listing problem. A five-fold spread swamps most of the fee differences between the same categories. Period: July to August 2026. Basis: Refunded units divided by units sold, aggregated by normalised category, July to August 2026 at roughly 70% category coverage.. As of: 2026-09-09. ### 15% to 35.5% | category-margin-spread Margin before advertising ranges from 15% of sales in Grocery to 35.5% in Clothing & Accessories, measured across the narrower panel of Amazon sellers who maintain cost of goods in Nova over July to August 2026. This is what is left to pay for advertising, overheads and profit. In the tighter categories the whole advertising budget has to come out of fifteen points of sales. Period: July to August 2026. Basis: Amazon-charged fees and seller-entered cost of goods divided by sales, margin taken before advertising, aggregated by normalised category, July to August 2026 at roughly 70% category coverage.. As of: 2026-09-09. ### 27.2% | acos-benchmark ACoS averaged 27.2% of ad-attributed sales over the twelve months to August 2026 on a fixed panel of several hundred Amazon sellers running ads continuously. This is the blended reality rather than a category target. If your ACoS sits far below it you are probably under-invested in advertising, and far above it you are buying sales that the margin cannot pay for. Period: September 2025 to August 2026. Basis: Ad spend divided by ad-attributed sales, aggregated across sellers running ads in at least nine of the twelve months to August 2026 with meaningful click volume. A ratio of same-currency quantities, so it is safe to blend across marketplaces.. As of: 2026-09-09. ### 3.68x | roas-benchmark ROAS averaged 3.68 times ad spend over the twelve months to August 2026 on a fixed panel of several hundred Amazon sellers running ads continuously. Every unit of ad spend returned about three and two thirds units of ad-attributed sales. ROAS is the inverse of ACoS, so read one and you have read the other. Period: September 2025 to August 2026. Basis: Ad-attributed sales divided by ad spend, aggregated across sellers running ads in at least nine of the twelve months to August 2026 with meaningful click volume. A ratio of same-currency quantities, so it is safe to blend across marketplaces.. As of: 2026-09-09. ### 6.42% | tacos-benchmark TACoS averaged 6.42% of total sales over the twelve months to August 2026 on a fixed panel of several hundred Amazon sellers running ads continuously. TACoS measures advertising against the whole business, not just the sales advertising claims. It is the number that tells you whether ad spend is buying growth or subsidising sales you would have made anyway. Period: September 2025 to August 2026. Basis: Ad spend divided by total sales, aggregated across sellers running ads in at least nine of the twelve months to August 2026 with meaningful click volume. A ratio of same-currency quantities, so it is safe to blend across marketplaces.. As of: 2026-09-09. ### 13.0% | ad-conversion-rate Ad clicks converted at 13.0% over the twelve months to August 2026 on a fixed panel of several hundred Amazon sellers running ads continuously, holding between 12.4% and 13.6% every month of the year. This is the most stable advertising number in the set. A conversion rate that moves outside that band is a listing, price or targeting problem, not a market movement. Period: September 2025 to August 2026. Basis: Ad-attributed orders divided by ad clicks, aggregated across sellers running ads in at least nine of the twelve months to August 2026 with meaningful click volume, monthly range reported alongside the annual figure.. As of: 2026-09-09. ### 0.615% | ad-click-through-rate Sponsored click-through rate averaged 0.615% over the twelve months to August 2026 on a fixed panel of several hundred Amazon sellers running ads continuously. Roughly six clicks per thousand impressions. Click-through rate is a creative and placement measure, so judge it against this level before blaming conversion. Period: September 2025 to August 2026. Basis: Sponsored ad clicks divided by sponsored ad impressions, aggregated across sellers running ads in at least nine of the twelve months to August 2026 with meaningful click volume.. As of: 2026-09-09. ### 23.6% | ad-share-of-sales Ad-attributed sales were 23.6% of total sales over the twelve months to August 2026 on a fixed panel of several hundred Amazon sellers running ads continuously, ranging from 13.8% in October to 31.9% in July. About a quarter of sales come through advertising, but the share swings by more than double across the year. Judge a month against the same month, not against the annual average. Period: September 2025 to August 2026. Basis: Ad-attributed sales divided by total sales, aggregated across sellers running ads in at least nine of the twelve months to August 2026 with meaningful click volume, monthly range reported alongside the annual figure.. As of: 2026-09-09. ### 23.8% | december-cheapest-ads December is the most efficient advertising month of the year: ACoS falls to 23.8% in the United States against a 27% to 31% range in every other month, and to 20.2% in the United Kingdom against a 22% to 27% range, measured over the twelve months to August 2026. Buyer intent in December does the work that budget has to do the rest of the year. If any month deserves a raised bid ceiling, it is this one, and most sellers instead pull back once peak week is over. Period: September 2025 to August 2026. Basis: Monthly ad spend divided by monthly ad-attributed sales, per marketplace, across sellers running ads in at least nine of the twelve months to August 2026 with meaningful click volume. Each figure is a ratio within a single currency and is never blended across currencies.. As of: 2026-09-09. ### 24.3% vs 28.1% | uk-cheaper-than-us-ads United Kingdom advertising is materially cheaper and more efficient than United States advertising, at GBP 0.52 per click and 24.3% ACoS against USD 1.00 per click and 28.1% ACoS, measured over the twelve months to August 2026. Two different currencies, so the cost per click figures are stated side by side and never averaged together. The efficiency gap holds on the ratio measures too, which are currency-free. Period: September 2025 to August 2026. Basis: Per-marketplace ad spend, clicks and ad-attributed sales across sellers running ads in at least nine of the twelve months to August 2026 with meaningful click volume. Currency values reported within their own currency only.. As of: 2026-09-09. ### USD 1.30 to USD 0.88 | us-cheaper-clicks-worse-conversion United States cost per click fell from USD 1.30 to USD 0.88 over the twelve months to August 2026 while the United States ad conversion rate fell from 13.9% to 9.5%, so clicks got cheaper and worked less well. A falling cost per click read on its own looks like a win. Paired with the conversion decline it means traffic quality dropped faster than its price, which is why ACoS did not improve with it. Period: September 2025 to August 2026. Basis: United States ad spend divided by clicks, and ad-attributed orders divided by clicks, first and last month of the window, across sellers running ads in at least nine of the twelve months to August 2026 with meaningful click volume. United States figures only, never combined with another currency.. As of: 2026-09-09. ### Advertising by marketplace Reported in each marketplace's own currency. Never blended across currencies. - United Kingdom: cost per click GBP 0.52, ACoS 24.3%, ROAS 4.11, TACoS 8.41%, ad conversion rate 13.16%. Period: September 2025 to August 2026. - United States: cost per click USD 1.00, ACoS 28.1%, ROAS 3.56, TACoS 10.65%, ad conversion rate 10.96%. Period: September 2025 to August 2026. ### Category economics Category attribution comes from the Amazon BSR display group, a field that was backfilled progressively: it covers 3.3% of sales in October 2025 and 76.5% in August 2026. This is a July to August 2026 snapshot at roughly 70% category coverage, not a twelve-month trend. Coverage improves every month. Category names are normalised across marketplace languages, so Home & Kitchen here includes its German, French, Spanish, Italian and Dutch equivalents, and the same applies to the others. Categories where the sample was too thin or too concentrated to publish responsibly are not shown. Period: July to August 2026. Cost of selling by category. Each fee line divided by sales, and refunded units divided by units sold, aggregated by normalised category across the wider panel of Amazon sellers, with no cost of goods requirement, over July to August 2026 at roughly 70% category coverage. Panel: the wider panel of Amazon sellers, with no cost of goods requirement. Period: July to August 2026. | Category | Amazon take % of sales | Referral % | FBA fulfilment % | Refund rate % of units | | --- | --- | --- | --- | --- | | Grocery | 39 | 12.8 | 22.5 | 1.76 | | Office Products | 38.4 | 14.4 | 21.3 | 2.16 | | Toys & Games | 32.2 | 14.6 | 14.2 | 4.23 | | Industrial & Scientific | 31.7 | 14.4 | 14.6 | 3.21 | | Health & Personal Care | 30.2 | 13.9 | 15.1 | 2.28 | | Clothing & Accessories | 30.1 | 16.5 | 13 | 9.87 | | Sports & Outdoors | 28.8 | 14.1 | 12.5 | 5.93 | | Home & Kitchen | 27.3 | 14.4 | 10 | 6.11 | Margin before advertising by category. Amazon-charged fees and seller-entered cost of goods each divided by sales, with margin taken before advertising, aggregated by normalised category across the narrower panel of Amazon sellers who maintain cost of goods in Nova, over July to August 2026 at roughly 70% category coverage. Panel: the narrower panel of Amazon sellers who maintain cost of goods in Nova. Period: July to August 2026. | Category | Margin before advertising % of sales | | --- | --- | | Clothing & Accessories | 35.5 | | Health & Personal Care | 28 | | Home & Kitchen | 21.2 | | Grocery | 15 | ## Latest State of Amazon issue August 2026: Amazon raised its take without touching commission The first State of Amazon computed from Nova's own panel rather than from public sources. Two years of Amazon accounts, more than 65 million units, measured the same way from September 2024 to August 2026. Amazon's total take reached 35.1% of sales while the referral commission did not move at all. URL: https://www.novadata.io/resources/state-of-amazon/2026-08 Published: 2026-09-09.

Between June and July 2025 Amazon replaced the flat coupon redemption fee with a performance fee plus a participation fee, visible in the fee ledger of a fixed panel of several hundred Amazon sellers.
