How much money do tattoo artists make hourly?

Depends on Artist and Skill level of the Artist. And A lot of times, it also depends on region where the Artist is Located.

Most artists will do around about of $100 an hour. This is more popular when you are getting a bigger tattoo that could take several sessions up to 8+ Hours.

If a artist believes it would be cheaper for you then a $100 hourly rate to finish a project, then most of the time they will put a one time price on a certain project.

So, to answer your question. Around $100+ an hour. But remember. They aren't always occupied with work from open to close at shops.
