The top % is calculated from data provided by Keepa.com. The method used to calculate the Top % is by taking the current BSR (rank) of the ASIN and then dividing it by the total number of items found in that amazon category according to Keepa, then converting it to a percent by diving by 100.

**For example:** If the Amazon category **Toys and Games **has a total of **8,253,112** products (according to Keepa) and the Current BSR of the ASIN you are looking at is **3,371,** then the Top % of that product is **0.04%**. Below is the breakdown of how to get this number.
