KDP Income Goal Calculator: How Many Sales Do You Need?

“How many books do I have to sell to make $1,000 a month?” This calculator answers that question. Enter your goal and your average royalty, and see the sales you need per month, per day and per book.

How to use this calculator

  1. Enter your monthly income goal.
  2. Enter your average royalty per sale.
  3. Enter how many books you plan to have published.

How the math works

Sales needed equals your income goal divided by your average royalty, rounded up. Divide that by 30 for daily sales, and by your number of books for sales per book.

Example: To earn $1,000 per month at $3.00 average royalty, you need 334 sales per month, about 11 per day. Spread over 10 books, that is about 33 sales per book per month.

Why a catalog beats a single book

Most KDP authors do not reach their goal with one book. Several books in the same niche share readers, help each other in Amazon’s recommendations, and make ads more efficient. Spreading the target across more books lowers the sales each one needs.

Tips to reach your goal faster

  • Raise your average royalty with sensible pricing before chasing more volume.
  • Build books in one niche so each launch helps the others.
  • Track real monthly numbers and update the calculator with your own average royalty.
  • Set a realistic timeline. Results usually build slowly over months.
