Amazon BSR to Sales Chart (2025)
Amazon's Best Sellers Rank (BSR) is a relative ranking, not a sales counter, so no exact formula turns a rank into copies sold. But after tracking thousands of books the relationship is predictable enough to chart. The table below gives rough daily sales for a given BSR in the US Kindle Store during an average month. Treat it as a ballpark, not a guarantee.
BSR to sales chart (US Kindle Store)

|---|---|---|
| #1 to #10 | 1,000+ | 30,000+ |
| #100 | 100 to 300 | 3,000 to 9,000 |
| #1,000 | 50 to 100 | 1,500 to 3,000 |
| #5,000 | 20 to 40 | 600 to 1,200 |
| #10,000 | 8 to 20 | 250 to 600 |
| #50,000 | 3 to 6 | 90 to 180 |
| #100,000 | 1 to 3 | 30 to 90 |
| #500,000+ | Less than 1 | A handful |
Why these are ranges, not exact numbers
BSR updates hourly and reflects how you're selling compared to every other book right now. In November and December the whole marketplace moves faster, so it takes more sales to hold a given rank; in a slow month the same rank takes fewer. The rank stays put while the sales behind it move.
Category matters too. Paperback (print) BSR runs slower than Kindle, so the same number means fewer copies. And one check tells you little, because the figure can swing within a day. What's useful is the trend over time.
For exact breakdowns at common ranks, see BSR 1,000, BSR 10,000, and BSR 100,000.
