Get a Free QuoteHow the Amazon Sales Estimator Works
Amazon doesn't publish unit sales, so estimators reverse-engineer them from a product's Best Sellers Rank (BSR) and sales-rank history. This free tool uses Keepa data: when Amazon shows a “bought in past month” figure we use that actual number, otherwise we estimate from the count of 30-day sales-rank drops — each drop roughly corresponds to a sale. Enter any ASIN and marketplace to see estimated monthly sales, revenue, current BSR and price, so you can validate demand before sourcing a product.
Frequently Asked Questions
How does the sales estimator work?
It pulls a product's data from Keepa by ASIN. If Amazon reports a “bought in past month” number, we show it; otherwise we estimate monthly units from the number of sales-rank drops over the last 30 days — a widely used proxy where each drop in BSR signals a sale.
How accurate are the estimates?
They're good directional estimates, most accurate in competitive, stable categories with steady data. Niche or seasonal products can vary more. Treat the numbers as a guide and validate before committing.
Which marketplaces are supported?
US, UK, Germany, France, Japan, Canada, Italy, Spain, India and Mexico — pick the marketplace, enter the ASIN, and the tool returns that marketplace's data.
