Stop guessing which book ideas will sell.

The KDP Niche Profitability Estimator helps self-publishers evaluate whether a niche is worth entering before investing time creating a book.

This spreadsheet tool allows you to plug in real Amazon data — including search results, average pricing, and estimated sales — to quickly determine potential revenue opportunities.

By calculating estimated royalties, competition levels, and market demand, the estimator gives you a clearer picture of whether a niche is profitable or oversaturated.

Whether you're creating journals, puzzle books, logbooks, or high-content books, this tool helps you make smarter publishing decisions and avoid wasting time on niches that won’t generate sales.

Perfect for:
• Low-content book creators
• Puzzle book publishers
• Journal creators
• New KDP authors
• Experienced self-publishers testing new niches

If you’re serious about building a profitable KDP catalog, this estimator helps turn niche research into a simple data-driven process.
