KDP vs IngramSpark: Which Publishing Platform Should You Use? (2026)
KDP vs IngramSpark: Which Publishing Platform Should You Use? (2026)
The short answer: use Amazon KDP for your main storefront (best royalties, 70% eBook, free to start) and IngramSpark for bookstore/library distribution (your own ISBN + expanded reach) — most serious authors use both. KDP reaches Amazon's massive audience; IngramSpark gets you into bookstores and libraries that Amazon can't. Here's the 2026 comparison.
KDP vs IngramSpark: Key Differences
| Factor | Amazon KDP | IngramSpark |
|---|---|---|
| Setup cost | $0 | ~$49 per title (revisions extra) |
| eBook royalties | Up to 70% | 60% (retail minus print cost) |
| Print distribution | Amazon only | Bookstores, libraries, 40,000+ retailers |
| ISBN | Free KDP ISBN (Amazon-only) | Requires your own ISBN (works everywhere) |
| Royalty reporting | Monthly, clear | Monthly, more complex |
| Bookstore returns | N/A | Books are returnable (inventory risk) |
| Best for | eBook sales + Amazon paperback | Bookstore presence, libraries, non-Amazon retail |
Why Authors Use Both
- KDP first: free setup, best eBook royalties, and Amazon is where most self-published sales happen.
- IngramSpark second: your book becomes orderable by any bookstore or library — the "professional availability" that opens doors.
- Own ISBN: with your own ISBN you can publish the same book on both platforms without conflict (don't use the free KDP-only ISBN if you plan IngramSpark too).
Cost Comparison for 2026
KDP: $0 to publish; you only pay print cost per copy sold. IngramSpark: ~$49 per title setup, plus print cost and possible revision fees. If you're publishing for Amazon sales alone, KDP is enough. If you want bookstores, libraries, or global non-Amazon reach, add IngramSpark — many authors find the ~$49 well spent.
