Is KDP Publishing Worth It in 2025? What Authors on Reddit Actually Say
Thinking about self-publishing on Amazon’s Kindle Direct Publishing (KDP)? You’re probably wondering if it’s worth the time, effort, and money—or if it’s just another overhyped side hustle that doesn’t deliver results.
Instead of giving you polished marketing speak, we analyzed hundreds of Reddit discussions from r/selfpublish, r/KindleUnlimited, and r/writing to see what real authors actually experience with KDP in 2025. Here’s what they’re saying—the good, the bad, and the honest truth.
Quick Answer: Is KDP Worth It?
Yes, if you:
- Write genre fiction (romance, fantasy, thriller, mystery)
- Can produce multiple books (series perform best)
- Understand basic marketing (or are willing to learn)
- Have realistic income expectations ($100-500/month initially is normal)
No, if you:
- Expect to get rich from one book
- Won’t invest in editing and cover design
- Think “just upload and wait” works
- Need immediate income (takes 3-6 months to build)
What Reddit Authors Say About KDP Income
Realistic First-Year Earnings
“Published my first novel 8 months ago. Made $143 total. But I published book 2 in the series last month and now I’m at $680/month. It snowballs.”
— u/ScienceFictionAuthor, r/selfpublish
“Three years in with 12 books published. Earning $3,200-$4,500/month consistently. Not quitting my day job yet but it pays my mortgage.”
— u/RomanceWriter22, r/selfpublish
“Published 1 book in 2023. Earned $8 total. Didn’t market it, used a bad cover, didn’t understand categories. Classic rookie mistakes. Starting over with better strategy.”
— u/FirstTimeAuthor, r/KindleUnlimited

The Biggest Complaints About KDP (From Reddit)
1. “Amazon Changes Rules Without Warning”
“They suspended my account for ‘quality issues’ after 2 years of publishing. No warning, no appeals. Lost $4k/month income overnight. Terrifying being dependent on one platform.”
— u/SuspendedAuthor, r/selfpublish
Reality: Amazon does enforce quality standards aggressively, sometimes incorrectly flagging legitimate books. Common triggers:
- Repetitive content across multiple books
- AI-generated content (increasingly flagged in 2024-2025)
- Public domain books with minimal added value
- Translated content without proper attribution
Reddit Advice: Diversify platforms (IngramSpark, Draft2Digital) so Amazon suspension doesn’t destroy your income.
2. “Kindle Unlimited Cannibalized My Sales”
“Enrolled in KU thinking I’d get more readers. I did—but sales dropped 90%. Now earning $0.43 per borrow instead of $2.79 per sale. Terrible decision for my non-fiction book.”
— u/NonFictionFail, r/selfpublish
Reality: KU works brilliantly for fiction series but often hurts non-fiction, literary fiction, and standalone novels.
Reddit Consensus:
- ✓ Use KU for: Romance, fantasy, thriller series
- ✗ Avoid KU for: Non-fiction, memoirs, high-priced books ($9.99+), literary fiction
3. “Marketing is 80% of the Work”
“Spent 2 years writing the perfect novel. Published it. Crickets. Realized I need to spend as much time marketing as I did writing. Nobody warned me.”
— u/MarketingNewbie, r/writing
Reality: “Build it and they will come” doesn’t work on Amazon with 12 million books. You must:
- Run Amazon Ads (expect $200-500 monthly budget to start)
- Build email lists (use BookFunnel, StoryOrigin for reader magnets)
- Optimize keywords and categories
- Get launch reviews (ARC readers are essential)
- Maintain social media presence
What Successful KDP Authors Do Differently (Reddit Patterns)
After analyzing hundreds of success stories, clear patterns emerge:
1. They Write Series, Not Standalones
“My standalone thriller: 50 sales/month, $140 income. My 5-book fantasy series: 2,000 KU borrows/month, $3,400 income. Series changed everything.”
— u/FantasySeriesAuthor, r/selfpublish
Why series work:
- Readers binge-read series, generating massive page reads
- First book in series becomes permanent advertisement for others
- Amazon algorithms favor authors with multiple books
- Loyal readers await new releases (built-in audience)
2. They Publish Consistently
| Publishing Frequency | Reddit-Reported Average Income |
|---|---|
| 1 book/year | $50 – $300/month |
| 3-4 books/year | $500 – $2,000/month |
| 6-8 books/year | $2,000 – $8,000/month |
| 12+ books/year | $5,000 – $30,000+/month |
Romance authors dominate the high-output categories. Fantasy/sci-fi authors typically publish 2-4 books/year.
3. They Invest in Quality Covers and Editing
“Spent $800 on professional cover and editing for my romance. Recouped it in month 2. My first book with DIY cover? Still hasn’t earned $800 after 18 months.”
— u/RomanceAuthor89, r/selfpublish
Reddit Budget Recommendations:
- Cover design: $200-500 (premade) or $500-1,200 (custom)
- Editing: $500-2,000 depending on length and depth
- Formatting: $50-150 (or use Vellum/Atticus)
- Total first book investment: $750-3,350
4. They Master Amazon’s Ecosystem
Successful authors obsess over:
- Keywords: Use Publisher Rocket or KDP Rocket to find high-traffic, low-competition keywords
- Categories: Choose “clickable” categories where your book can rank top 20
- Pricing strategy: $0.99-2.99 for series starters, $3.99-5.99 for later books
- Launch tactics: ARC reviews, preorder campaigns, launch day Amazon Ads blitz
KDP vs. Traditional Publishing (Reddit Opinions)
| Aspect | KDP Self-Publishing | Traditional Publishing |
|---|---|---|
| Royalties | 35-70% | 7-15% (after agent cut) |
| Time to Market | 1-4 weeks | 12-36 months |
| Upfront Costs | $750-3,350 | $0 (publisher pays) |
| Creative Control | 100% | Limited (publisher decides) |
| Marketing Support | You handle everything | Minimal (unless you’re a big name) |
| Prestige | Lower (but growing) | Higher |
| Income Ceiling | $500K+/year possible | $50K-200K typical (mid-list) |
“Got traditional deal for $15K advance. Earned out in 6 months, now getting $0.87/book. Self-pubbed my next series on KDP. Earning $6K/month. Never going back.”
— u/FormerTraditional, r/selfpublish
Common KDP Mistakes (According to Reddit Veterans)
Mistake #1: Pricing Too High
Reddit wisdom: New authors pricing at $9.99 kill their discoverability. Start at $2.99-3.99 to get initial traction.
Mistake #2: Ignoring Blurb/Description
Reddit wisdom: Your book description sells your book, not your cover. Study bestseller blurbs in your genre and model yours after them.
Mistake #3: Not Building Email Lists Early
Reddit wisdom: “I published 8 books before starting an email list. Biggest regret. Now rebuilding an audience I already had.”
Mistake #4: Quitting After Book 1 Flops
Reddit wisdom: “Book 1 earned $34 total. Book 2 earned $180. Book 3 earned $1,200 (series momentum). Don’t quit early.”
Mistake #5: Using AI-Generated Content Carelessly
2025 update: Amazon increasingly flags AI content. Reddit reports accounts suspended for ChatGPT-written books without substantial human editing.

— u/FullTimeKDPAuthor, r/selfpublish, 2025
Bottom line: KDP works for authors who treat it as a business, not a lottery ticket. The authors succeeding in 2025 are the ones publishing multiple quality books per year and mastering Amazon’s ecosystem.
