Frequently Asked Questions
What is Best Seller Rank (BSR)?
BSR is a number Amazon assigns to products based on recent sales performance within a category. A lower BSR generally means stronger recent sales in that category.
How accurate are these estimates?
Use the results as directional estimates, not guaranteed sales numbers. Actual sales can vary with seasonality, price, reviews, stock status, listing quality, category movement, and marketplace competition.
Why does category matter?
A rank has different meaning in each category. A BSR of 5,000 in a high-volume category can represent very different sales velocity from the same BSR in a smaller category.
Which marketplaces does this estimator support?
This version supports UK and US marketplace/category inputs. Use the same marketplace and category shown on the Amazon product page for the cleanest estimate.
Is this tool free to use?
Yes. The sales estimator is free to use without signup. It is intended to help sellers sanity-check demand before deeper sourcing, margin, or repricing work.

Sales estimator methodology
BSR estimates are useful, but they are not magic. This is how to read the output without fooling yourself.
BSR is category-relative
The estimator treats rank as a category signal, not a universal sales number. That is why marketplace and category are required before a result is shown.
Results are directional
The output is useful for shortlisting products, but it should be checked against real Seller Central data, Keepa-style history, or a test order plan before buying stock.
Context changes the result
Seasonality, stockouts, price changes, reviews, ads, fulfilment method, and category volatility can all move actual sales away from a rank-based estimate.
