The same list price leaves a different share in your hands depending on where the book sells. Count the share, not the sticker.
The real cost difference isn’t setup fees. It’s the royalty each one pays and the wholesale discount IngramSpark needs in order to sell on Amazon, and the answer depends on where your book sells. KDP wins on Amazon-side economics, and IngramSpark wins on distribution beyond Amazon.
Authors comparing the two often start with setup fees and printing costs, and those numbers hide the ones that actually decide what they earn.
I’m Daniel J. Middleton, and I’ve been designing books for authors and publishers for close to twenty years now — the part I still love most is finding the design that makes an author’s message land.
This piece breaks down what each platform pays, what IngramSpark requires to compete on Amazon, and how the two fit together on cost.
Why Do Setup Fees Matter Less Than Royalty and Discount Structure on KDP and IngramSpark?
Because neither platform charges to set up a title. KDP charges nothing to publish, and IngramSpark title setup costs nothing today either, as what IngramSpark still charges after setup explains. What separates them is royalty structure and discount requirements.
What Does KDP Pay You on an Amazon Sale?
On Amazon, KDP sets the terms and takes its share automatically. You don’t choose a discount. KDP pays 60% of your list price on Amazon.com at $9.99 and up, and 50% at $9.98 and below, minus printing costs. The rates and break points vary by marketplace, so check KDP’s current Paperback Royalty page.
KDP’s own example is a $15 paperback, 333 pages, black ink, sold on the US marketplace. After $5.00 in printing costs, it pays $4.00 per sale.
What Discount Does IngramSpark Need to Sell on Amazon Well?
On IngramSpark you set the wholesale discount yourself, and it pays you the wholesale price minus printing costs. IngramSpark’s own help center says a 53% to 55% discount with returns enabled generally gives a book the widest availability through retailers and bookstores.
Amazon is where the discount matters most. In my experience, you can’t list a book on Amazon through IngramSpark at anything below a 55% discount and still expect normal delivery windows and accurate list pricing. That’s the real cost of trying to sell on Amazon through IngramSpark instead of going direct through KDP.
Where Does IngramSpark Win on Cost?
Outside Amazon. IngramSpark’s strength was never Amazon. It’s expanded, worldwide distribution, where it’s well ahead of KDP, and it’s how a book reaches bookstores, libraries, and retailers beyond Amazon.
Here’s the same $15 book, before printing costs, in each channel:
KDP on Amazon (60% rate): $9.00.
KDP Expanded Distribution (40% rate): $6.00.
IngramSpark at a 55% wholesale discount (45% of list): $6.75.
Printing costs differ between the platforms, and IngramSpark has fees of its own, so run each platform’s calculator with your book’s actual specs before you decide.
Is It Cheaper to Buy Author Copies Through KDP or IngramSpark?
Both sell author copies at printing cost plus shipping. In my clients’ experience, KDP has usually come out cheaper. That may have changed, so price the same order on both, shipping included, before you buy.
Cost comparisons between print platforms come down to one number: the share of the list price that reaches you in the channel where the book actually sells.
How Should You Split Print Distribution Between KDP and IngramSpark to Keep Costs Down?
Let each platform do what it’s best at. KDP wins on Amazon-side economics, and IngramSpark wins decisively on worldwide distribution. It’s the same split behind using each platform for what it’s best at, seen from the cost side.
The next step is running your own numbers against where you actually plan to sell, not choosing by sticker price. If you’d like help setting both platforms up, the get-started page is where to begin.
