Is Amazon KDP Free to Use?

Quick Answer: Yes. Amazon KDP charges no fees for account creation, manuscript upload, or publishing. There is no upfront cost. Amazon makes money through the royalty split: you receive 35% or 70% of the sale price, and Amazon keeps the rest. The only deduction beyond the royalty split is a delivery fee on the 70% plan (approximately $0.15 per megabyte of file size).

KDP is free in the same way that selling on any marketplace is "free." You don't pay to list your product. You pay a percentage of each sale. If your book doesn't sell, you owe nothing.

How the Royalty Structure Works

The 70% royalty plan is available for ebooks priced between $2.99 and $9.99 in eligible marketplaces. Amazon deducts a delivery fee based on file size (roughly $0.15 per MB). For a text-only ebook of about 1 MB priced at $4.99, you'd earn approximately $3.34 per sale ($4.99 x 70% minus $0.15 delivery).

The 35% royalty plan applies to ebooks at any price point and has no delivery fee. For a book priced at $0.99, you'd earn about $0.35 per sale. For a book priced at $4.99, you'd earn about $1.75.

The 70% plan is almost always the better choice for books priced between $2.99 and $9.99. The 35% plan applies automatically for books priced outside that range.

What About Print?

KDP Print (paperback and hardcover) is also free to use. Amazon deducts a printing cost per copy sold, which varies by page count, trim size, and ink type. You set your list price and earn the difference between the list price and the combined printing cost and Amazon's distribution share. You never pay for printing upfront.

Bottom Line

KDP is genuinely free to use. No account fees, no upload fees, no monthly charges. Your cost is the royalty share Amazon takes from each sale. For the full KDP process, see Amazon KDP Setup and Upload.
