How much money can one Kindle book make? (1 year case study)

What probably sticks out first is just how much the United States and the United Kingdom take up in sales. Over 95% of the sales come from the US and UK and while you make think that it’s just the niche for my book but with my other pen names in other non marketing niches I’ve seen similar numbers.
Holy Cow Batman – $377 Per Month – I Should Go Buy A New Car!
If I were a younger version of myself (more of an idiot that is to say) I could go out and buy a new car for about $25,000 with 3% interest and a 6 year term and this one book could pay for my car payments.
But you are not like the younger me are you? You’re reading this blog, working on ways to make extra money and – most importantly – keeping your personal expenses low so you can both retire sooner (if that’s your thing) and have money to invest in your business.
You may even buy a cheapo house like me as well right?
(Perhaps in your country or your part of the US $130k isn’t cheap, but compared to West Seattle homes at $500k where we were looking it is cheap)
Of course it’s not certain that I will continue to earn $377 per month from this book either. The internet is always changing and certainly the material in my book will need some degree of on going attention and updating.
I’ve already updated the book roughly 5 times to account for changes with Google (i.e. removal of Google Adwords Keyword Tool, reduced influence of exact match domain names etc).
Make Money With The Kindle Owners Lending Library Program (KOLL)
For this book I joined KDP select which allows me 5 free days to give the book away for free every 90 day period (good for promos and to get early reviews). This is an exclusive program which requires you to not publish the book anywhere else other than Amazon.com.
With that said the KOLL program is something different that allows Amazon Prime members to borrow one free KDP select book per month. To compensate authors they will pay you when Amazon Prime members borrow your book for free – nifty right?
So how much money can you make from people borrowing your book for free?

So take advantage of these wonderful opportunities the internet provides to everyone. To see an example of how to take advantage of it go to: http://visitwebpages.info/paypalchecks/
