Frequently Asked Questions
How accurate is the KDP royalty calculator?
Our calculator uses Amazon's official royalty structures and printing cost formulas to provide accurate estimates. However, actual costs may vary slightly based on specific book dimensions, paper choices, and regional differences. Always verify final costs through your KDP dashboard before publishing.
Should I choose 35% or 70% royalty for my Kindle book?
Choose 70% royalty if your book is priced between $2.99-$9.99 and you want maximum profit per sale. Choose 35% royalty for books priced outside this range, for maximum global distribution, or if you want to avoid delivery cost deductions for large files with many images.
How long does it take to start earning money with KDP?
You can start earning immediately after your book goes live, but significant income typically takes 3-6 months of consistent marketing effort. Success depends on book quality, genre competition, marketing skills, and pricing strategy. Building a sustainable income usually requires multiple books and ongoing promotion.
What's the difference between KDP and traditional publishing royalties?
KDP typically offers higher royalty percentages (35-70%) compared to traditional publishing (10-15% for print, up to 25% for digital). However, traditional publishers provide advances, professional editing, marketing support, and broader distribution. KDP requires authors to handle all aspects of publishing and marketing themselves.
