Free Amazon Monthly Sales Tracker
Enter any Amazon ASIN to see the estimated number of units bought in the past month — the same 'X bought in past month' signal Amazon shows on the listing.
How the Amazon Monthly Sales Tracker works
Enter an ASIN and your email, and the tool queries the Amazon product page in real time to read the "bought in past month" sales signal Amazon now surfaces on many listings. It reports the estimated number of units sold in the last 30 days, giving you a quick read on demand for any product — yours or a competitor's.
Data is pulled live via the Asgard Data API, the same product endpoint that also returns title, rating, reviews, images and BuyBox details.
Frequently asked questions
Is this Amazon sales estimator really free?
Yes. You can estimate monthly sales for any ASIN at no cost. It is powered by the Asgard Data API and offered as a free utility for Amazon sellers and researchers.
How accurate is the monthly sales number?
The figure reflects Amazon's own 'bought in past month' indicator, which Amazon displays on the listing. Not every product shows this signal — when Amazon does not publish it, the tool reports that no estimate is available rather than guessing.
What is an ASIN?
An ASIN (Amazon Standard Identification Number) is a 10-character identifier for every Amazon product. You'll find it in the product URL or the details section of the listing. It usually starts with B0.
Can I check competitor sales?
Yes. The tool works on any public ASIN, so you can benchmark competitor demand alongside your own catalog.
