That's a horribly vague question. You didn't even specify country. It depends on how successful you are. If you're at the bottom of the pile (assistant, student, even) then next to nothing or minimal depending who you're working for.
On the other hand, the Sailor Moon artist doesn't even need to draw or work anymore because she has that much money (and still does) from just royalties alone.
"Not much.
The average Manga Ka looks at roughly 8-10 hour days, sometimes more, sometimes less. Generally they have a 20-40 page submission to fulfill every month so you're looking at one compleated page every day, not including the time it takes to write the story, if the editor doesn't like it you having to re-do it, and extra art like cover art or graphic books.
You don't get an hourly rate but a contract based partially on sales, the average contract is usually for a beginner 500$ per 20 pg's + 10-15% royalties.
Which assuming it takes 5 hours per page about 5$ per hour.
And that's if you don't hire assistants. If you do then their cut comes out of your salery. And you do pay them an hourly rate, not a by contract."

Manga artists (mangaka) only get paid if their manga become very, very popular, like Inuyasha. Rumiko became one of the richest people in Japan because of her manga.
Akira Toriyama made huge money on Dragon Ball, but his taxes got high and he was doing one-shots and you don't get paid good for one-shots. So he lost a lot of money over the years, but thanks to game design he was able to get most of it back. So yeah they can make pretty big money if their manga are popular.
