Amazon Sales Estimator

Pick a category and drop in any product's Best Sellers Rank (BSR). Get an instant estimate of how many units it moves per month, so you know if there's real demand before you buy.

Product details

Tip: the BSR is on every Amazon listing under "Product information" / "Best Sellers Rank." Use the rank for the main category, not a sub-category.

Estimates are directional, based on typical US BSR-to-sales curves by category. Real numbers vary with seasonality, price, and competition. For exact tracking, watch the listing's BSR over time.

Free Live Training

Demand is half the equation. I'll show you the other half live.

Every Thursday at 8 PM EST I run a free 60-minute training where I find a product with real demand, check the profit, and source it on camera. Come watch.

How the Amazon sales estimator works

Every product on Amazon has a Best Sellers Rank (BSR), also called sales rank. A lower number means it sells more. BSR #1 in a category is the top seller; BSR #100,000 barely moves. The catch: the same BSR means very different sales in different categories, because each category has a different number of products competing.

Reading the result

This tool maps the BSR you enter to a typical monthly unit estimate for that category. Use it to sanity-check demand before you buy. A product ranked 1,000 in Home & Kitchen sells far more than one ranked 1,000 in a tiny niche.

What's a good BSR for arbitrage?

For online and retail arbitrage you usually want products that sell at least a few units a day and aren't dominated by Amazon or one giant seller. Steady mid-range demand beats a single hot item that sells out and dies. Pair this with the profit math in the FBA Profit Calculator to find deals that actually make money.
