Paste a seller ID or storefront link to estimate the whole store's monthly revenue from Amazon's own sales figures.
Sales figures: Amazon's "bought in past month" badge and prices, via Keepa. Estimates, not the seller's accounts.
Paste an Amazon seller ID, a storefront link or one of the seller's products, and see roughly what the whole store sells a month. We add up Amazon's own "bought in past month" figure times the price across every listing in the store that shows one, the same method behind every Amazon case study on this site. The first lookup is free; a free account unlocks more.
We publish the real numbers behind Amazon businesses: revenue, profit, margin and what it cost to start, with every figure sourced. One email when a new case study is out. Get emails on new case studies
First we find the seller's full catalogue, not just the products on its brand-store page. A storefront page is a shop window: for White Mountain Puzzles it showed 43 products when the seller actually listed 497. Then we take every listing that carries Amazon's "bought in past month" badge, best sellers first, and add up badge × current price (the buy box where Keepa has it, otherwise the lowest new offer).
The result is a range, because every badge is a floor bucket: "1K+" is 1,000 to 1,999. The low end is what Amazon's figures prove the store sold at least; the high end is what they allow at most for those listings.
On 10 November 2026, MaryRuth Organics' storefront had 281 listings, 196 of them with a badge. The top 100 alone added up to between $14.2 million and $21.2 million a month. Our MaryRuth case study, built by the same method across the full year, puts it at about $15 million.
A seller ID is the code after seller= in the link on a seller's name: open any product, click the seller's name next to "Sold by", and copy the address. It starts with an A and is 13 or 14 characters long, like A3C12G0C3DENHY. You can also paste a product link or ASIN and we look up who holds its buy box. Brand-store links (/stores/…) do not contain the seller ID, so they will not work on their own.
Store results are cached for up to three days.
Add up what each of its listings sells. Amazon shows a "bought in past month" figure on listings above about 50 orders a month; multiply each by its price and sum them across the seller's whole catalogue. This calculator does that from a seller ID. Revenue is not profit: after Amazon's fees, product cost and ads, the businesses we profile keep between about a fifth and a half of it.
Yes. The first store lookup needs nothing. After that, a free account (email only, or Google) unlocks up to 20 lookups a day. Product-level lookups on the sales estimator need no account at all.
Not reliably, so we do not offer it. Brand names on Amazon are free text: a search for one common word matches thousands of unrelated listings. A seller ID identifies exactly one business. Paste one of the brand's products and we find its seller for you.
It is a floor, by construction, and usually a close one for brands whose sales are concentrated in a few listings. It runs low for stores with long tails of small listings or more than 100 badged products. For the businesses we have profiled in full, it lands in the same range as the case study.
No, revenue only: a store's costs are not public. For one product, the Amazon sales estimator works out Amazon's fees and profit per unit at a product cost you enter.
