What is roughly the deal authors get for kindle books? 

(ie they get a % of each sale)

70% for ebooks, 60% for physicals...was just researching this the other day. free to publish on there but amazon owns exclusive sales rights unless u buy ur own isbn # separately

This does not take into account if you have a publisher who may be taking a % too right?

Ur self-publishing on kindle for free so no fees for that

Definitely does not take into account publishers
