How I Made $990 Selling 6 Medium Content Books On KDP!

During the last 90 days, I have made $990 by selling 6 medium content books on Amazon KDP. 

Out of those 6 books, 5 are math workbooks and one is a coloring book. 

In this article, I will break down things like the total units sold per book, total royalties by title, and my total ad spent for the last 90-day period.

You can also see a big blue line with indicates my best day in terms of royalties. Yes, I made well over $100 in a single day. That happened because one of my math workbooks got a bulk order on OCT 6. 

I also had some very good days and some not-so-good-earning days. On my good days, I was making around $25 per day and on slower days I earned $2 or less.

So, on average I made $330 per month with 6 kdp titles. Now have a look at royalties by title.

kdp ad spend last 90 days

In total, I spend over $571 (US Dollars) on kdp ads. I spend the majority of my ad budget on 3 books only. I tested ads for the other three titles as well but they didn’t make any good ROI.

I got 2,701.17 in total sales and my ACost (Advertising Cost) was 21.15% which is great. My ads got 1,542 clicks to get these 2,701.17 sales.

My Net KDP Income

So, after netting expenses, my net kdp income stayed at $419 which is not huge. However, the good thing is I made a good profit every single month. 

On average I made an extra $139 per month which I think is a good return on investment considering the fact I only published that many books.

Final Thoughts

Making money with Amazon kdp is more about strategy and less about luck. 

If you publish good quality books, and you utilize the book promotion options like kdp ads, you can make decent money with fewer books.  

You can see I made the most money with 3 books out of these 6 books. Now I can scale these books even further by increasing my ad spend and tweaking my book description and A+ Content.
