Why is my IngramSpark royalty so much lower than KDP?

IngramSpark uses a wholesale model: retailers take a 40–55% discount off list, and you absorb that discount. KDP pays a fixed 60% (minus print cost) on Amazon-direct sales. For Amazon sales specifically, KDP almost always pays more.

What discount should I choose?

55% with returns enabled if you want bookstores and libraries to stock the book. 40% if you only need online distribution. Below 40% blocks most physical retail.

Does this include Amazon's cut?

Yes — when your book is sold through Amazon via IngramSpark, Amazon takes the full wholesale discount you set. The royalty shown here is what reaches you.

IngramSpark Royalty Calculator

Estimate your IngramSpark royalty per copy after the wholesale discount and print cost. Unlike Amazon KDP's fixed-percentage royalty, IngramSpark uses a wholesale model: you set the list price and the discount retailers get, and your royalty is whatever's left after print cost.

When Amazon shows your book at a sale price and you want to see the math.

Formula

Royalty per copy = (List price × (1 − Wholesale discount %)) − Print cost

Worked example

A 280-page B&W paperback listed at $16.99 with a 55% wholesale discount and a $4.20 print cost.

Publisher revenue = 16.99 × (1 − 0.55) = 16.99 × 0.45 = $7.65
Royalty per copy = 7.65 − 4.20 = $3.45
Royalty as % of list = 3.45 ÷ 16.99 = 20.3%

Answer: $3.45 royalty per copy (~20% of list)

More worked examples

Hardcover at $29.99, 55% discount, $7.10 print cost.

Publisher revenue = 29.99 × 0.45 = $13.50
Royalty = 13.50 − 7.10 = $6.40
Margin = 6.40 ÷ 29.99 = 21.3%

Answer: $6.40 royalty per copy

Same paperback at 40% discount instead of 55%.

Publisher revenue = 16.99 × 0.60 = $10.19
Royalty = 10.19 − 4.20 = $5.99

Answer: $5.99 — but bookstores rarely stock at 40%

How it works

IngramSpark pays publishers the difference between the wholesale price and the print cost. The wholesale price equals list price minus the discount you grant retailers. A 55% discount with returns enabled is what most physical bookstores require to actually stock the title.

Because the discount is your single biggest lever, the same book listed at the same price earns very different royalties depending on whether you've set up for trade distribution (55%) or only direct/library sales (40%).

Expert tips

Match KDP's pricing on Amazon — if your IngramSpark list price is higher, Amazon will favor the KDP edition.
Always test 55% with returns enabled if you want bookstore distribution. 40% only buys you libraries and online retailers.
Run this calculation in both USD and GBP — UK print costs and royalties are different.
If the royalty is negative, raise list price or use a lighter interior (B&W standard vs premium color).

How to interpret your results

Dollar values are shown per sale, per order, or per item unless a result is explicitly labelled monthly, weekly, or daily.
Percentages (margin, ROI, conversion rate) are easier to compare across products and price points than raw dollars — use them when you benchmark.
A positive result means you're ahead after the costs and fees you entered. A negative result means the current numbers don't work — change a lever (raise price, cut a cost, lower ad spend) and recalculate.
Treat the output as a planning estimate, not a guarantee. Fees, taxes, and conversion rates shift over time — re-run the numbers whenever a key input changes.

Limitations

Doesn't include payment-processing fees from direct sales channels.
Print cost is an estimate — confirm in your IngramSpark dashboard for your exact trim size.
Amazon's wholesale terms can change; we use the published 55% standard.

Common mistakes

Forgetting that the discount comes out of YOUR royalty, not the list price the reader pays.
Using KDP's 60% royalty assumption — IngramSpark math is entirely different.
Pricing too low to support a 55% discount and a healthy royalty at the same time.
Ignoring returns reserves on physical bookstore copies.
