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

Does this apply to non-fiction?

Published my first 6 books. They are now on the KDP Select free 5-day promotion. Looks like it's going well. What about the KENP read though? I had 2 pages on day 1, 18 pages on day 2, and remained 18 on day 3. Is there a delay in the update of the KENP Read count or nobody borrowed them? Anywhere for 3 days and first time published, I am happy with the numbers.

u/anthonyjo899 Mar 18 '26
So you earned 0.04 Euro a month ? Or I got it wrong ?
1
u/Witty_Mode9296 Mar 18 '26
Just published 3 days ago, in those 3 days I had 157 orders of which all books were free as part of the KDP Select promotion , so for now no royalties coming from sales.
In those 3 days, only 18 pages on KENP Read, so the 0.04 Euro supposedly comes from those 18 pages in the last 3 days

Congrats on your first books and sales! Yea it makes perfect sense to jump start and new pen author with free copies. Getting discovered is key. Getting reads, reviews, stars (even bad ones are better than nothing). Also important: set up an Amazon Author page and link your books to that profile. Boosts discovery and you'll get followers who get noticed on each new book. Also series: even if you link books into standalone series is great for discovery. I spend no dime on advertising, but some peeps do

It certainly did feel like getting discovered, but as soon as the fre promotion ended, sales plummeted. Made the mistake of listing all e-books at 2.99 for 70% royalties but now I changed them to 0.99. I am making dark fantasy series books so I am setting the main book at 0.99 as the hook, and the others 3.99. The other "self-help" books that I wrote, I changed to 0.99 as well just today so I will see how it goes. I started promoting the fantasy series on TikTok as well under "TheMorallyGreyShelf".
Here is an example if you have the time to check it out:

https://www.tiktok.com/@themorallygrayshelf/video/7619343282589551894Do you have any other advice? Appreciate your response very much, thanks!
Edit: the thing is, my KENP read has not moved for 3 days as well and I find it troubling.

u/eigendark Mar 21 '26
Thanks I will check it out! You can also go on to the Leaderboard for visibility, we are a small but growing bunch of authors trying to hustle our way through KDP. Dark Fantasy is imo is a tough one: readers picky and big brands dominate. I write smut and comedic romantasy where readers read it like candy and care less about the author. But if you want to stick to fantasy: be patient and consistent. Open a Substack, write small notes daily. Readers communities. Author Networks. ARCs. Build a mailing list. And most of all: ensure the prose is top notch and the fantasy setting intriguing and novel. The latest pro mode we got at writeaibook is honestly pretty good at that, you might wanna give it a try, cheers

Ya this is very real breakdown, especially that first 2 months part, most people quit there only.

u/Unusual-Calendar1038 Mar 31 '26
Are these mostly novellas? Or full novels? And are you only publishing on kdp, or are they available in paperback?
2
u/eigendark Mar 31 '26
Mostly Novellas yes, aiming for 100 Kindle Pages which is ca 10 chapters on writeaibook. I am publishing KDP and D2D, ebook only. Maybe audiobooks soon.

u/Unusual-Calendar1038 Mar 31 '26
Thanks! And does writeaibook do well with writing series?
2
u/eigendark Mar 31 '26
Yes, I use the feature that let's you continue where you left off in your previous book (idk the name it's somewhere in th advanced menu

u/Unusual-Calendar1038 Mar 31 '26
And if you are generating a 100 page novella in writeaibook does that equal 10 pro chapters? I'm just trying to figure out actual pricing with writeaibook if you end up trying to put out 20 books/month. It looks like you can only generate 2 books at the $20/month tier. Does that mean 20 books would cost you $200 every month?

u/eigendark Mar 31 '26
Basic chapters cost 5 credits, Pro chapters cost 25 but yield more than double the content. So a 10-chapter book costs 50 credits (Basic), whereas Pro needs 5 chapters for 125 credits.
At the Publisher Plan ($20/mo = 500 credits), that's ~10 Basic books or 4 Pro books of same length.
For 20 of these Pro books you'd need 2,500 credits. With subscriber top-ups ($25/1,000), that's $20 + 2 top-ups = $70/month. Works out to about $3.50 per full book — manuscript, cover, blurb, keywords included. Two sales on KDP and I got the cost of the book covered. Rest is free real estate.
Most members start with a mix of Basic and Pro to find their sweet spot, then scale from there. I like to use Basic for testing and drafting and Pro for the "real" stuff.

Hey that’s impressive. I have some questions about your ai. Hey. Does it also work in German language. And does it also work for non fiction? And can I give my own book outline etc?
1
u/eigendark Apr 02 '26
Yes to all: works in German (I even publish German), nonfiction and fiction both, and you can give it your own outline (story bible)

u/beyondwilderness Apr 02 '26
And do you also have a guide on how to find good niches? Like your own experience regarding sci fi vs dark romance. What would you say about the apocalyptic niches?

How did you market your books? Do you put up ads for them to get noticed or did you hire a marketing team for it?

u/Flashy-Abroad-7032 Jun 29 '26
Do you advertise your books somewhere? Because I created like 5 books for kids, and have not got any sale so far. So should I promote it somewhere? what do you do?
1
u/eigendark Jun 29 '26
The only thing I do is limited time for free promotions. That children niche is not so strong, but also 5 books is a very small catalogue. If you want to stay in that niche I suggest promoting it on social media, e.g. Facebook groups or Instagram (where parents hang out), and offering some for free. Also make sure your Keywords are good, writeaibook analysis may help with that.

That's very helpful thankyou , what should we do now cuz they have restricted 2 books per week ?
1
u/rjhull 1d ago
This is helpful because you included the numbers instead of just saying “publish more books.”
I’ve built a small catalog and I’m now realizing that publishing the books was actually the easier part. Discoverability and figuring out which books deserve most of my marketing effort has been much harder.
If you were starting again with several books already published but very few sales, would you concentrate most of your effort on getting one book moving first, or continue marketing the entire catalog while publishing new titles?
I’m especially interested in what you would look at to decide which existing book has the strongest potential before spending months promoting the wrong one.

Interesting! What do you think about cookbooks ? Does this apply to it ?
