Amazon Sales Estimator
Rank to units, with the caveats stated.
Rank-to-sales conversion is an estimate built on a power-law assumption, not data from Amazon. It is useful for comparing two products in the same category and unreliable as an absolute figure.

Treat this as a comparison tool, not a forecast. Rank-to-sales curves differ enormously between categories, they move with seasonality, and Amazon publishes nothing. Two products ranked 4,000 in different categories can sell an order of magnitude apart.
How the Amazon Sales Estimator works
Rank-to-sales estimates rest on a power-law assumption that Amazon has never confirmed. They are genuinely useful for comparing two products in the same category, and unreliable as absolute figures — two products ranked 4,000 in different categories can sell an order of magnitude apart.
Not financial advice. Marketplace fees change, and they vary by country, plan and seller status. Every rate here is an editable default, not a quoted price — check the platform's current fee schedule before you price a product against it. This is not tax or business advice.
Frequently asked questions
How accurate are sales estimators?
Directionally useful within a category, poor across categories, and worst at the extremes of rank. Treat any specific number as an order-of-magnitude guess.
Where does the estimate come from?
A fitted curve relating rank to sales, calibrated on whatever sales data the tool's owner has. Amazon publishes nothing, so every estimator is inferring from a sample.
Why does category matter so much?
Because category size and demand distribution differ. Rank 5,000 in a category with three million products means something very different from rank 5,000 in one with fifty thousand.
What is a better signal?
Calibrating against your own product's rank and known sales in the same category. The category curve cancels out of the ratio, which makes the comparison far more reliable than any absolute estimate.
