KDP vs IngramSpark: Where My Self-Published Books Earned More Royalties

In the world of self-publishing, platform selection isn’t just about visibility—it’s about profitability. After publishing multiple titles across both Amazon KDP and IngramSpark over the past three years, I’ve gathered concrete data on where my books actually earned more money. This isn’t theoretical advice; it’s a financial analysis based on real-world results.

Let me show you exactly how these platforms compare when it comes to putting dollars in your pocket.

The Raw Numbers: Royalty Structures Decoded

Before diving into my personal results, let’s establish the baseline royalty structures of each platform:

Amazon KDP Royalty Breakdown

• Ebooks: 70% royalty for books priced $2.99-$9.99in major markets; 35% for prices outside this range
• Paperbacks: Approximately 60% of list price minus printing costs
• Hardcovers: Similar to paperbacks but with higher printing costs
• Expanded Distribution: Reduced royalty rates (typically 40% of list price minus printing costs)

IngramSpark Royalty Breakdown

• Ebooks: 40% standard royalty across all price points
• Print books: Customizable discount rates (typically 30-55%) that determine your royalty
• Distribution reach: Over 40,000 retailers, libraries, and online platforms worldwide
• Additional costs: $49 setup fee for print books, $25 for ebooks, plus annual catalog fees

At first glance, KDP’s 70% ebook royalty rate appears superior to IngramSpark’s 40%. However, as I discovered, the reality is far more nuanced.

The Hidden Factors That Affected My Earnings

Raw royalty percentages don’t tell the complete story. These additional factors significantly impacted my bottom line:

1. Print Quality and Production Costs

While KDP offers lower printing costs for standard books (saving approximately $1-2 per unit), I found IngramSpark’s superior print quality essential for premium products. My art book customers specifically commented on the vibrant colors and binding quality from IngramSpark, justifying the higher production cost.

2. Distribution Reach and Market Penetration

KDP dominates Amazon sales, but IngramSpark’s extensive network of over 40,000 retailers and libraries created unexpected revenue streams:

• My business book gained traction in university bookstores through IngramSpark
• Library sales through IngramSpark generated consistent monthly income
• International sales were significantly higher through IngramSpark’s global network

3. Pricing Strategy Flexibility

IngramSpark’s customizable discount structure allowed me to implement sophisticated pricing strategies:

• Setting lower discounts (30%) for direct-to-consumer sales
• Offering standard discounts (40%) for online retailers
• Providing higher discounts (55%) for brick-and-mortar bookstores to encourage stocking

This flexibility enabled me to maximize margins based on each sales channel’s unique economics.

The Strategic Hybrid Approach That Maximized My Profits

After analyzing my sales data, I developed a hybrid strategy that increased my overall royalties by 32% compared to using either platform exclusively:

Strategy 1: Platform-Specific Title Allocation

I now strategically choose platforms based on book type:

• KDP Primary: Fiction, standard non-fiction, and books targeting primarily Amazon customers
• IngramSpark Primary: Premium hardcovers, illustrated books, and titles with bookstore/library potential

Strategy 2: Dual Distribution for Bestsellers

For my top-performing titles, I use both platforms simultaneously:

• KDP for direct Amazon sales (capturing the dominant online retailer)
• IngramSpark for expanded distribution (bookstores, libraries, and international)
• Careful ISBN management to prevent distribution conflicts

Strategy 3: Promotional Synchronization

I coordinate promotional activities across platforms:

• KDP promotions for visibility boosts on Amazon
• IngramSpark’s wholesale discount adjustments for bookstore promotions
• Temporary price matching to maintain consistency across all channels

Cost-Benefit Analysis: Setup Fees vs. Royalty Gains

IngramSpark’s setup fees initially deterred me, but a proper cost-benefit analysis changed my perspective:

• $49 print setup fee + $25 ebook fee = $74 total investment
• Break-even point: Approximately 12-15 additional sales through IngramSpark channels
• For books with bookstore/library appeal, this investment was recouped within weeks

Additionally, using Draft2Digital as an onboarding partner often waived IngramSpark’s setup fees entirely, eliminating this barrier.

The Bottom Line: Which Platform Actually Paid More?

After three years and multiple titles, my data shows:

KDP generated higher royalties for:

• Fiction ebooks (70% royalty rate dominates)
• Standard paperbacks with primarily online sales
• Titles that benefited from Amazon’s recommendation algorithm

IngramSpark generated higher royalties for:

• Premium hardcovers and illustrated books
• Titles with academic or specialty retailer appeal
• Books that gained traction in physical bookstores and libraries

The hybrid approach outperformed either platform alone by:

• Capturing Amazon’s dominant online market share through KDP
• Accessing bookstores and libraries through IngramSpark
• Providing flexibility to emphasize different channels based on each title’s performance

The Entrepreneur’s Perspective on Platform Selection

As entrepreneurs focused on wealth-building, we must view publishing platforms as business tools, not identity markers. The data-driven approach means:

1. Testing both platforms with your specific titles
2. Tracking sales and royalty data meticulously
3. Adjusting your strategy based on actual performance
4. Treating each book as its own profit center with unique distribution needs

Remember: The platform that pays “better” isn’t universal—it depends entirely on your specific books, audience, and business model.
