For the artists that don't think about it and for the collectors buying art, the price tag is broken down many times.
For a piece of art that sells in a gallery for $1000, the gallery genereally gets 50%. That leaves the artist with $500. The frame might cost the artist $75 if he or she is lucky. That leaves $425. Then the government at the end of the year will want about 25 to 30% of that leaving the artist with a total of about $260 for that $1000 painting. That's the reality of being a painter and trying to make a living at it. Think about it! But not too much because you might become depressed.
