Amazon KDP vs IngramSpark

If you're self-publishing a print book, two names dominate the conversation: Amazon KDP and IngramSpark. New authors almost always frame it as a contest — which one should I pick? — and then spend hours trying to crown a winner.

Here's the secret the pros know: it's usually not an either/or decision. KDP and IngramSpark are built for different jobs, and the smartest publishing setups often use both. But to make that call confidently, you need to understand exactly how each platform handles royalties, printing, distribution, ISBNs, formats, and fees in 2026 — because several of those numbers changed recently.

This guide breaks it all down in beginner-friendly terms, with side-by-side tables, real royalty math, and a clear recommendation framework.

Quick answer: Amazon KDP earns you the most money on Amazon sales and is the

easiest place to start, with free setup and a free ISBN. IngramSpark gives you professional-grade distribution to bookstores and libraries, more hardcover options, and a returnable setting — but thinner margins on wide channels. Most serious indie authors use KDP for the Amazon paperback and Kindle edition, and IngramSpark for hardcover and everywhere-else distribution.

Amazon KDP (Kindle Direct Publishing) is Amazon's free self-publishing platform. You upload your ebook and print files, set a price, and your book appears on Amazon — by far the largest book retailer in the English-speaking world. KDP is optimized for one thing above all: selling on Amazon.

IngramSpark is the indie-author platform of Ingram Content Group, the world's largest book distributor. It prints on demand and pushes your title into the wholesale catalog that bookstores, libraries, and retailers everywhere use to order books. IngramSpark is optimized for reach beyond Amazon.

That difference in purpose explains almost every other difference between them.

Keep this table handy — the rest of the guide explains the why behind each row.

This is the section that matters most, so let's be precise.

As of June 2025, KDP uses a tiered print royalty:

60% of list price minus printing cost — for books priced at or above the marketplace threshold (about $9.99 in the US; ~£7.99 in the UK).

50% of list price minus printing cost — for books priced below that threshold. So the formula for a US paperback priced at or above the threshold is:

(List price × 60%) − printing cost = your royalty

Example: A $16.99, 280-page black-and-white paperback with a ~$4.60 print cost: (16.99 × 0.60) − 4.60 = $5.59 per copy sold on Amazon.com.

That's a strong margin — and it's why Amazon is where most indie authors make most of their money.

IngramSpark doesn't use a flat percentage. Your earnings are whatever's left after the retailer's wholesale discount, the printing cost, and the market access fee:

List price − (list × wholesale discount) − printing cost − (list × 1.875%) = your compensation

Example: The same $16.99 / 280-page book, at the standard 55% wholesale discount and ~$4.40 print cost: 16.99 − 9.34 − 4.40 − 0.32 = $2.93 per copy through IngramSpark's wide channels.

The $5.59 vs. $2.93 difference isn't IngramSpark being stingy. It's the cost of reach. To make your book attractive to an actual bookstore, you offer a 55% wholesale discount so the store and the distributor both make money. On Amazon, you're effectively the retailer, so you keep the retail margin. Wide distribution is a different economic deal than direct-to- consumer sales.

Channel Royalty on $16.99 paperback

KDP (direct Amazon sale) ~$5.59

KDP Expanded Distribution ~$2.20 (40% − print)

IngramSpark (55% discount) ~$2.93

Ebooks: A Quick Note

For ebooks, the comparison tilts toward KDP for most authors. KDP pays 70% on ebooks priced $2.99–$9.99 (minus a small per-megabyte delivery fee), and 35% outside that range. It also offers KDP Select, an exclusivity program that puts your ebook in Kindle Unlimited and pays per page read — but exclusivity means you can't distribute that ebook through IngramSpark.

IngramSpark distributes ebooks to Apple Books, Kobo, Nook, and library systems like OverDrive — valuable if you're going "wide" rather than Amazon-exclusive. Many authors who want both Kindle Unlimited and wide ebook reach end up using a dedicated ebook aggregator (like Draft2Digital) instead of IngramSpark for the ebook specifically.

This trips up more beginners than almost anything else.

KDP will assign you a free ISBN — but it lists an Amazon imprint as the publisher of record, and that ISBN can only be used within KDP.

IngramSpark requires your own ISBN, which you buy from Bowker (in the US). That ISBN lists you (or your imprint) as publisher.

If you ever want the same book on both platforms with a consistent identity, you need your own ISBN. A KDP free ISBN cannot be carried over to IngramSpark. This is why

experienced authors buy their own ISBNs from the start — read the ISBN Guide for Self- Publishers before you make this choice, because it's hard to undo.

Both platforms print on demand at high quality (and IngramSpark and KDP actually share some printing infrastructure). The meaningful differences:

Hardcovers: IngramSpark wins decisively. It offers case-laminate and cloth-bound editions with optional dust jackets. KDP's hardcover program is more limited in trims and binding styles. For gift books, children's books, and anything libraries will buy, IngramSpark's hardcover range matters.

Color printing: Both offer color; IngramSpark gives more control over paper and color tiers, which matters for illustrated and children's titles.

Trim sizes: IngramSpark offers a wider catalog of trim sizes, including oversize options useful for workbooks and journals.

Fee type KDP IngramSpark

Title setup $0 $0

ISBN $0 (branded) You buy your own

Revisions Unlimited, free Free during grace window, then a fee

Distribution None (Expanded Distribution just lowers 1.875% market access fee on fee royalty to 40%) distributed sales

Author copies Print cost + shipping Print cost + shipping

The big behavioral implication: KDP forgives mistakes; IngramSpark charges for them. On KDP you can re-upload a corrected interior at 2 a.m. for free. On IngramSpark, post- grace-window changes cost money, which is why the platform rewards authors who upload finished, proofed, professionally formatted files.

Scenario 1 — "I just want to publish my novel and sell it on Amazon." Start with KDP only. It's free, fast, forgiving, and the Amazon margin is excellent. You can add IngramSpark later.

Scenario 2 — "I want my book in local bookstores and libraries." You need IngramSpark, with a 55% returnable discount. KDP's Expanded Distribution technically reaches some of these channels, but bookstores strongly prefer ordering through Ingram and won't stock non-returnable titles. See Expanded Distribution vs IngramSpark.

Scenario 3 — "I'm publishing a hardcover gift book / children's book." IngramSpark for the hardcover (especially jacketed), almost certainly. Possibly KDP too for the Amazon paperback.

Amazon paperback + Kindle; IngramSpark for hardcover + wide distribution, with the Amazon paperback channel turned off on IngramSpark to avoid undercutting your better KDP margin. This is the standard "pro" setup — detailed in Should You Use Both KDP and IngramSpark?

1. Buy your own ISBNs (a 10-pack from Bowker). Assign separate ISBNs to your

paperback, hardcover, and ebook.

2. Publish the paperback + Kindle ebook on KDP using your own paperback ISBN. This captures the best Amazon margin and Kindle reach.

3. On KDP, do not enroll the paperback in Expanded Distribution (you'll handle wide distribution through Ingram instead).

4. Publish on IngramSpark the hardcover and the paperback for wide distribution — but disable the Amazon channel on IngramSpark so Amazon orders flow through your higher-margin KDP listing.

5. Set 55% + returnable on IngramSpark for bookstore appeal.

6. Confirm pricing matches across platforms so readers see a consistent price.

Rather than a single "winner," match the platform to the kind of author you are: The first-timer testing the waters. You want to publish, learn the ropes, and not get overwhelmed. → Start KDP-only. It's free, forgiving (unlimited free revisions), and the Amazon margin is strong. You lose nothing by adding IngramSpark later.

The fiction author building a readership. Your bread and butter is Amazon and Kindle, with paperbacks for fans and possibly bookstore events down the line. → KDP for Kindle + paperback, IngramSpark for wide paperback and a hardcover collector edition once you have momentum.

The children's-book or illustrated author. Hardcover (especially jacketed) and color quality are central, and libraries/gift shops are real buyers. → IngramSpark leads for hardcover and wide reach; KDP supplements for the Amazon paperback.

The nonfiction "authority" author. You speak, consult, or sell from a platform, and a hardcover doubles as a credibility object and speaker gift. → Both, with IngramSpark carrying the hardcover and bookstore presence and KDP carrying the Amazon paperback + Kindle.

The low-content publisher (journals, planners, notebooks). Amazon is your main market, and these formats face restrictions in some wide channels. → KDP-centric, with

IngramSpark only if you specifically want these titles in wider distribution (it allows low- content books that KDP's Expanded Distribution often won't).

The "go wide on everything" author. You're deliberately diversifying away from Amazon dependence. → Both, plus possibly a dedicated ebook aggregator for non-Kindle stores. The throughline: the question isn't "which platform is better?" but "which platform is better for this format and this channel?" Once you frame it that way, the dual setup stops feeling like overkill and starts feeling obvious.

The ebook side deserves a closer look because the platforms diverge most here.

KDP's 70% tier applies to ebooks priced $2.99–$9.99 in major territories, minus a small per- megabyte delivery fee. Outside that band you earn 35% (with no delivery fee and global availability). This is why the vast majority of indie ebooks are priced between $2.99 and $9.99 — it's a deliberate incentive to keep you in the high-royalty zone.

KDP Select adds Kindle Unlimited, where you're paid from a monthly global fund based on pages read (a fraction of a cent per page). The trade-off is exclusivity: your ebook can't be sold or distributed anywhere else while enrolled. For some authors — especially in romance and other genres with heavy KU readership — Select earns more than wide distribution ever would. For others, locking yourself to one retailer is a strategic risk.

library systems like OverDrive. It's valuable if you're going wide, but many authors find a dedicated ebook aggregator (such as Draft2Digital) gives more retailer control for the ebook specifically, while reserving IngramSpark for print. There's no single right answer — it depends on whether KU's per-page income or wide reach matters more for your genre.

Ebook path Reach Royalty Exclusivity

KDP (no Select) Kindle 70% / 35% No

KDP Select Kindle + KU 70% + KU page reads Yes (exclusive)

IngramSpark / aggregator Apple, Kobo, Nook, libraries Varies by store No

Many authors start on KDP and want to add IngramSpark months later. It's very doable, but a few things make it smooth:

1. Check your ISBN. If your KDP paperback uses a free KDP ISBN, you can't carry it to IngramSpark — you'd publish the IngramSpark edition under a new (your own) ISBN. If you used your own ISBN on KDP, you can reuse it.

2. Turn off Expanded Distribution on KDP before enabling wide distribution on

IngramSpark, so the two don't collide in non-Amazon channels.

3. Disable Amazon as a channel on IngramSpark so your higher-margin KDP listing keeps the Amazon sales.

4. Match the list price so readers see one consistent number.

5. Order a fresh proof from IngramSpark — even for a book already "done" on KDP — because print can vary between manufacturers.

The lesson most migrating authors wish they'd known earlier: buy your own ISBN from the start. It's the one decision that's genuinely annoying to reverse. See the ISBN Guide for Self-Publishers.

Treating it as either/or. The biggest missed opportunity. These tools complement each other.

Letting both platforms feed Amazon. If both your KDP and IngramSpark listings supply Amazon, you can end up with the lower-margin (or duplicate) listing winning the buy box. Pick one source for Amazon — usually KDP.

Using a free KDP ISBN, then hitting a wall. You can't move that book to IngramSpark with the same identity. Buy your own ISBN up front.

Pricing for KDP margins, then losing money on Ingram. A price that earns nicely on Amazon can earn almost nothing after a 55% wholesale discount. Price for both channels, or accept thinner Ingram margins as a marketing cost.

Enrolling in KDP Select, then expecting wide ebook distribution. Select requires Kindle exclusivity. You can't be exclusive and wide at the same time for that ebook.

Beginners: start on KDP, graduate to "both." There's no penalty for adding

IngramSpark in month three.

Always order proofs from both platforms. Print can vary slightly between

manufacturers.

Match your metadata (title, subtitle, author, description) across platforms so your book looks like one consistent product to retailers and readers.

Use the threshold rule on KDP. Pricing a US paperback at $9.99+ keeps you in the 60% tier; dropping below means 50%. That single decision can be worth a dollar a copy.

Track where sales actually come from before investing heavily in wide distribution. If 95% of your sales are Amazon, your energy may be better spent on Amazon ads than chasing bookstore orders.
