IngramSpark vs KDP comes down to one question: do you want maximum royalties on Amazon, or maximum distribution everywhere else? KDP wins on Amazon sales and ease of use. IngramSpark wins on bookstore and library distribution. Most successful self-publishers in 2026 use both.
In this comparison, you’ll learn:
- How royalties, printing costs, and fees stack up side by side
- Which platform gives you better distribution reach
- When to use KDP alone vs. a hybrid strategy with IngramSpark
- How to decide based on your specific book and goals
Here’s the full breakdown.
At a Glance
| Feature | Amazon KDP | IngramSpark |
|---|---|---|
| Best For | Amazon sales, ebooks, beginners | Bookstores, libraries, global reach |
| Setup Fees | Free | Free (since 2023) |
| Printing Cost (6×9, 150pg B&W) | ~$2.80 | ~$3.38 |
| Ebook Royalty | 35–70% | N/A (use aggregators) |
| Paperback Royalty | 60% of list minus print cost | List minus wholesale discount minus print cost |
| Distribution | Amazon + limited expanded | 45,000+ retailers, libraries, bookstores |
| Ease of Use | Beginner-friendly | Steeper learning curve |
| Formats | Paperback, hardcover, ebook | Paperback, hardcover, ebook |
| ISBN | Free Amazon ISBN or your own | Your own required |
| Wholesale Discount | Set by Amazon | You choose (typically 55%) |
Royalties: KDP Pays More Per Amazon Sale
KDP royalties are straightforward. You earn 60% of your paperback’s list price minus printing costs on Amazon. For ebooks, you choose between a 35% or 70% royalty rate depending on your price point.
Since June 2025, KDP introduced tiered paperback royalties. Books priced at $9.99 or above earn 60%. Books below that threshold earn 50%. This matters if you’re pricing aggressively for a series launch.
IngramSpark royalties work differently. You set a wholesale discount — typically 55% for bookstore placement — and your royalty is whatever’s left after that discount and printing costs. On a $15.99 paperback with a 55% discount, your take might be $3.81 compared to $6.79 on KDP for the same book sold on Amazon.
The key insight: KDP pays more per sale on Amazon. IngramSpark pays less per sale but reaches thousands of retailers Amazon can’t.
If you’re trying to make money self-publishing, understanding these royalty structures is the first step to maximizing your income.
Distribution: IngramSpark Reaches 45,000+ Retailers
This is where IngramSpark dominates. IngramSpark distributes through Ingram’s massive catalog network to over 45,000 bookstores, libraries, online retailers, and academic institutions worldwide. Your book appears on Barnes & Noble, Target, Walmart, independent bookstores, and international markets.
KDP’s distribution is Amazon-first. You can opt into KDP Expanded Distribution for paperbacks, but it’s limited. KDP uses Ingram Book Group for expanded distribution and takes a 20% cut of your already-reduced royalty.
Bottom line: If bookstore and library placement matters to you, IngramSpark is the clear winner. If 90% of your sales will come from Amazon anyway — which is true for many self-publishers — KDP alone might be enough.
Wide Publishing vs KDP Select: The Exclusivity Question
KDP Select locks your ebook into Amazon exclusively for 90 days. In exchange, you get access to Kindle Unlimited, Kindle Countdown Deals, and Free Book Promotions. For some genres — particularly romance and sci-fi — KDP Select drives significant revenue through page reads.
Wide publishing means distributing your book across multiple platforms simultaneously. You list on Amazon through KDP, on bookstores through IngramSpark, and on other retailers through aggregators like Draft2Digital.
The wide vs exclusive debate depends on your genre and strategy:
- Go KDP Select if: You write in KU-heavy genres (romance, LitRPG, thriller), you’re building an audience, and Kindle Unlimited page reads represent meaningful income.
- Go wide if: You write literary fiction, nonfiction, children’s books, or anything where bookstore/library presence matters. Also smart if you want to avoid platform dependence on Amazon.
Many authors start exclusive with KDP Select, build their readership, then go wide with IngramSpark when they have a backlist.
Printing Costs: KDP Is Cheaper
KDP consistently undercuts IngramSpark on printing costs. For a standard 6×9 black-and-white paperback at 150 pages:
| Cost Component | KDP | IngramSpark |
|---|---|---|
| Fixed charge | $0.85 | ~$0.90 |
| Per-page charge | $0.012/page | ~$0.013/page |
| Total (150 pages) | ~$2.65 | ~$2.85 |
| Color interior (150 pages) | ~$5.50 | ~$6.20 |
KDP’s lower print costs mean higher margins on every Amazon sale. This advantage compounds across a catalog of books.
That said, IngramSpark’s slightly higher costs come with better print quality control, more trim size options, and access to their distribution network. You’re paying for reach, not just ink on paper.

KDP Expanded Distribution: Worth It?
KDP Expanded Distribution is Amazon’s attempt at wider distribution for paperbacks. When you enable it, your book becomes available through online retailers and bookstores that order from Ingram.
Here’s the catch: your royalty drops to 40% of list price minus print cost. And bookstores rarely order from KDP Expanded Distribution because:
- No returnability (bookstores want to return unsold stock)
- Wholesale discounts aren’t competitive
- Ingram’s listing shows it as a KDP title, not a publisher title
IngramSpark solves all three problems. You set your own wholesale discount, enable returnability if you choose, and your book appears as a legitimate publisher listing in Ingram’s catalog.
If distribution beyond Amazon matters, skip KDP Expanded Distribution and use IngramSpark directly. You’ll earn more and get better placement.
Best Print on Demand for Books: How They Compare
Choosing the best print on demand for books depends on your priorities. Here’s how the major POD players stack up:
| Platform | Best For | Distribution | Print Quality |
|---|---|---|---|
| KDP Print | Amazon sales, ebooks, beginners | Amazon + limited expanded | Good |
| IngramSpark | Bookstores, libraries, global | 45,000+ retailers | Excellent |
| Lulu | Direct sales, branded storefronts | Limited | Good |
| Barnes & Noble Press | B&N storefront placement | B&N only | Good |
| Draft2Digital Print | Easy wide distribution | Growing network | Good |
For most self-publishers, the choice is between KDP and IngramSpark — or using both. Lulu fills a niche for authors who want to sell books on their own website with branded fulfillment.
Lulu vs IngramSpark: Quick Comparison
Lulu vs IngramSpark is a common follow-up question. Lulu offers a simpler setup and a direct-to-consumer storefront, but its distribution reach doesn’t compete with IngramSpark’s 45,000+ retail partners.
Choose Lulu if you primarily sell through your own website, at events, or want to order author copies cheaply. Choose IngramSpark if you want your book in bookstores, libraries, and on major retail sites worldwide.
For wide distribution, IngramSpark wins every time.
Ease of Use: KDP Is Simpler
KDP’s interface is built for self-publishers. You upload your manuscript, set your price, and your book is live within 72 hours. The dashboard is intuitive, the help docs are solid, and you don’t need publishing experience to get started.
IngramSpark assumes you know what you’re doing. You’ll need your own ISBN, properly formatted files (no hand-holding on margins or bleed), and an understanding of wholesale pricing. The dashboard is functional but less polished.
If you’re publishing your first book, start with KDP. You can always add IngramSpark later when you understand the business side.
Formatting Requirements
Both platforms have specific formatting requirements, but they differ in strictness.
KDP accepts:
- PDF, DOCX, EPUB, or KPF files
- Provides free formatting tools (Kindle Create)
- More forgiving of minor formatting issues
IngramSpark requires:
- Print-ready PDF with proper bleed, margins, and embedded fonts
- Separate cover PDF meeting exact specifications
- Stricter file validation
If formatting feels overwhelming, tools like Atticus or book formatting software can generate print-ready files for both platforms simultaneously.
ISBN Requirements
KDP gives you a free ISBN for paperbacks and hardcovers. The downside: Amazon is listed as the publisher, and you can’t use that ISBN anywhere else.
IngramSpark requires you to provide your own ISBN. In the US, ISBNs come from Bowker — $125 for one, $295 for ten. You’re listed as the publisher, and you can use the same ISBN across platforms.
Best practice: Buy your own ISBNs in bulk. Use them on both KDP and IngramSpark. This gives you consistent publisher branding and portability across platforms. Many serious self-publishers treat ISBNs as a cost of self-publishing that pays for itself in professionalism.
The Hybrid Strategy: Use Both
The smartest approach in 2026? Use both platforms.
Here’s how the hybrid strategy works:
- Publish your ebook and paperback on KDP — You get maximum royalties on Amazon, which accounts for 70-80% of online book sales.
- Publish your paperback and hardcover on IngramSpark — You get distribution to bookstores, libraries, and international retailers.
- Use the same ISBN on both platforms for print editions.
- Disable KDP Expanded Distribution — IngramSpark handles non-Amazon distribution better and pays more.
- Price strategically — Set a slightly higher list price to account for IngramSpark’s wholesale discount while keeping KDP pricing competitive.
This gives you the best of both worlds: Amazon dominance through KDP and worldwide reach through IngramSpark.
Our Pick — Chapter

When to Choose KDP Only
KDP alone makes sense when:
- You’re publishing your first book and want simplicity
- Your target readers buy primarily on Amazon
- You’re writing in a Kindle Unlimited-heavy genre
- You don’t need bookstore or library distribution
- You want to minimize upfront costs (free ISBNs, no separate accounts)
Many successful indie authors earn six figures exclusively through Amazon self-publishing. KDP isn’t a “lesser” option — it’s the right option for Amazon-focused strategies.
When to Choose IngramSpark
Add IngramSpark when:
- Bookstore placement matters for your genre or goals
- You’re targeting libraries (especially for children’s books or literary fiction)
- You want international distribution beyond Amazon’s reach
- You’re building a publisher brand with your own ISBNs
- You want hardcover options with premium distribution
The Verdict
For Amazon sales: KDP wins. Higher royalties, lower printing costs, simpler setup.
For bookstore and library distribution: IngramSpark wins. No contest — 45,000+ retail partners vs. KDP’s limited expanded distribution.
For most self-publishers: Use both. Publish on KDP for Amazon dominance and IngramSpark for everywhere else. Disable KDP Expanded Distribution to avoid conflicts.
The real question isn’t which platform to choose — it’s whether your book is ready to publish. If you’re still writing, Chapter’s AI writing tools can help you finish your manuscript faster so you can stop comparing platforms and start selling books.
FAQ
Is IngramSpark better than KDP?
IngramSpark is better than KDP for bookstore and library distribution, reaching over 45,000 retail partners worldwide. However, KDP pays higher royalties on Amazon sales and is easier to use. Most successful self-publishers use both platforms together for maximum reach and revenue.
How much does IngramSpark cost?
IngramSpark is free to set up — they eliminated title setup fees in 2023. Your costs are printing fees (similar to KDP but slightly higher) and the wholesale discount you offer retailers (typically 40–55% of list price). You’ll also need your own ISBN, which costs $125 for one or $295 for ten from Bowker.
Can I use both KDP and IngramSpark?
Yes, you can use both KDP and IngramSpark simultaneously for the same book. Publish your ebook and paperback on KDP for Amazon sales, and your print editions on IngramSpark for bookstore distribution. Use the same ISBN on both and disable KDP Expanded Distribution to avoid channel conflicts.
What is KDP Expanded Distribution?
KDP Expanded Distribution is Amazon’s option to distribute your paperback beyond Amazon through Ingram Book Group and other wholesale channels. However, it offers lower royalties (40% of list minus print costs), no returnability, and limited bookstore adoption. Most authors get better results using IngramSpark directly for non-Amazon distribution.
Should I go wide or stay in KDP Select?
Whether to go wide or stay in KDP Select depends on your genre and goals. KDP Select works best for romance, sci-fi, and thriller authors who benefit from Kindle Unlimited page reads. Wide publishing through IngramSpark and other platforms works better for nonfiction, literary fiction, and children’s books where bookstore and library presence drives sales.
