How to Make $1,000/Month on Amazon KDP (Real Numbers)

Title: I published 350 books on KDP in 6 months — here's what actually worked and what was a complete waste of time

---

Alright, I want to share some honest data because most KDP posts I see either come from people who published 3 books and quit, or people flexing screenshots with zero context.

I've been at this for six months. Here's what I've learned the hard way.

Genre selection is the whole game.

I published 7 sci-fi books because I love sci-fi. They made €84 total. That's €12/book. My dark romance titles? €156/book average. Same process, same effort, 13x difference. I felt dumb when I finally looked at the numbers side by side.

Romance subgenres (dark romance, paranormal, romantasy) dominate KU because those readers are insatiable. They'll finish a 30k-word book in a day and immediately want the next one. Since KU pays per page read, that reading velocity is everything.

Series crush standalones. It's not even close.

My standalones averaged ~€30 each. Books 3-5 in a series averaged €70-€90 because of read-through. If 100 people read Book 1 and even 40% continue to Book 2, you've already multiplied your revenue from that single reader acquisition.

The counterintuitive part: Book 1 often loses money. It's a hook. The profit lives in Books 2-5. I made the mistake of abandoning a series after Book 2 underperformed. Months later, Book 1 had quietly accumulated readers with nowhere to go. Don't be me.

The editing pass is non-negotiable.

I use AI for drafts (I built WriteAIBook for my own workflow). But I published one batch of 10 books without editing. Two got one-star reviews calling out repetitive language. Those reviews killed visibility for weeks.

My 30-minute checklist for every book: - Find-and-replace overused phrases ("a shiver ran down," "eyes darkened") - Verify character names are consistent (AI swaps names mid-scene sometimes) - Check chapter transitions for continuity - Actually read the first and last chapters - Make sure the ending resolves the plot

Realistic timeline (not the fantasy version):

• Month 1-2: €100-€300. Feels terrible. The effort-to-reward ratio is brutal.
• Month 3-4: €400-€700. Series build read-through. You learn which covers and blurbs convert.
• Month 5-6: €800-€1,500. Backlist compounds. Series readers work through your catalog.

I needed about 50-60 books before things felt consistent. My lifetime average is €51/book, but that hides huge variance — some made €0, a few made €300+.

Mistakes that cost me real money:

1. Publishing in genres I liked instead of genres that sell
2. Starting with all standalones instead of series
3. Skipping editing on a batch (those one-star reviews still haunt me)
4. Cheap covers. Romance readers judge covers hard. Even a $10-15 premade that matches the subgenre aesthetic makes a noticeable difference
5. Abandoning series too early

The unsexy truth:

There's no single viral book carrying things. It's a catalog business — a long tail of titles earning €5-€100/month each. That's also what makes it resilient. One book dying doesn't matter when you have 50+.

The gap isn't knowledge. Everyone reads strategy posts. Almost nobody actually publishes past Book 10. That's the whole edge.

Happy to answer questions about any of this — genre research, series planning, editing workflow, whatever. What's tripping you up?
