Books
Every title, with its royalties, ad spend, net profit and True ACOS — the page that tells you which books to keep advertising.
One row per title, sorted by net profit. This is where you find the book that sells beautifully and still loses money.
The columns
| Column | Meaning |
|---|---|
| Sold units | Copies sold in the range |
| Royalties | Gross royalties, all channels including Kindle Unlimited |
| Royalties / sale | What one copy really earns you, after Amazon's cut |
| Ad spend | Spend attributed to this title, VAT included |
| Net profit | Royalties kept minus that spend — red when negative |
| True ACOS | Ad spend ÷ ad-generated royalties. Over 100 % is a loss on the ad-driven part |

Reading the table
- Negative net profit — the ads cost more than the book returns. Check whether it is book 1 of a series before pausing anything, in Series.
- True ACOS above 100 % with positive net profit — organic sales are covering the ad losses. Fragile, but not fatal.
- Low royalties per sale — often a paperback where print costs eat the margin.
What is not in a book row
Ad spend Amazon cannot tie to an ASIN — Sponsored Brands, and ads on ASINs outside your KDP catalog — belongs to no single title. It is counted in your global net profit but not in any row here, so the rows can add up to more than your total.
