eBook Royalty Calculator

Spend More Time Writing, Less Time on Admin...


If you are an indie author who self-publishes your writing on any of the big platforms, working out your pricing can be a minefield. There's different commissions depending on your price, and these aren't consistent between marketplaces. If you publish your work on KDP, you also have to take filesize into consideration, and don't forget the new EU Digital VAT rules affect your profit too!


The eBook Royalty Calculator is a simple, straightforward answer, needing just three numbers...
•  Your selling price in USD - make sure that it ends in .99 if you want to see a commission level for iBooks, otherwise pick your price!
•  VAT rate - if your price excludes VAT or you're selling to a country outside of the EU or you're selling to someone in your own EU country, leave this at zero. To find out how it would affect your profit otherwise, enter the relevant VAT amount (more help is available in the app)
•  File size - if you list on KDP (Amazon Kindle), you need to think about how large your files are, whether you are on the 35% or 70% royalty rate.


There's comprehensive help, including an explanation of all commission rates and this calculator really is a nifty way to stop your brain from melting, helping you spend more time writing!

Please note: We've tried to be as accurate as possible but royalties and rates may change or be different from prices listed. This calculator is intended as a guide to help authors with pricing, and is not to be relied on as an accurate calculation of revenue.

And app permissions? Some of them are needed for us to show ads, and ones that are relevant rather than for products in a country half way around the world. We only use ad-networks that we know are reputable, and whilst no-one ever says "gosh, I love ads" but we have to pay the bills somehow! Some of the other permissions are for us to send occasional push notifications - like when we launch an ad-free version!
