How Many Books Do You Need to Sell to Hit Your KDP Income Goal?

Books you need per month = your monthly income goal ÷ your royalty per book. At $2.50 per book, a $1,000/month goal needs 400 sales a month — about 13 a day. At $5 per book, it's 200 a month. Your royalty per book is the lever that changes everything.

Ebooks: 70% royalty for books priced $2.99–$9.99 (minus a small per-MB delivery fee), or 35% outside that range. A $4.99 ebook at 70% earns roughly $3.40.

Paperbacks and hardcovers: since 2025, 60% of list price minus printing cost for books priced $9.99+, and 50% minus printing cost below that. Printing cost depends on page count and ink — a 300-page black-and-white paperback costs around $4.60 to print.

Kindle Unlimited: pays per page read (about $0.004–$0.005), which adds up separately if you're enrolled.

This is why two authors with the same goal can need wildly different sales numbers. Use the KDP Royalty Calculator to find your real per-book figure.

Most individual books sell modestly. Authors who hit consistent income usually do it with a catalog — many titles each contributing a few sales a day — rather than one breakout book. Splitting a 400-books-a-month goal across 10 titles means each one only needs about 40 sales a month, which is far more realistic than expecting one book to carry it.

This calculator shows what you'd need to sell, not what you will sell. The large majority of KDP books sell only a handful of copies a month, and earnings vary enormously by niche, quality, pricing, and promotion. Treat the number as a target to build toward, not a guarantee.

Publish more titles — the single biggest factor for most authors.
