The income on the art is about 50% of the selling price when working with a gallery. If you sell something for $5,000, you're probably only getting about $2,250 [$5000 – $500 (the collector’s discount) =4,500 divided in 2 (the gallerist gets 50%) = $2,250)]. Do the math: profit from the sale of artwork minus the cost of making the work. Who will pay for materials and a place to make the work? Keep your expenses low. If your expenses are low, then you maybe you won't have to work at a day job. But, in most cases you're being flat out foolish if you don't consider having a second career. Unless you are independently wealthy or have a partner who will support you, you will need income to ride out periods of no sales or low sales. What are your options? What is it that you want from the art market? There are choices!
Teaching: As an artist, even if you are making enough income from art sales, you should have a plan for economic stability as you age. If you feel that you have something to offer and your communication skills are good, teaching is a possibility. Working in kindergarten through 12th grade is a five day a week job, in exchange you get steady income and benefits. You get more studio time if you teach at community college or a 4-year college. However, it is more difficult to get a full-time job in academia, especially in the 4 year institutions, than in K through 12. Furthermore, you must weigh the benefits of a full-time job or adjunct work. Financially it’s better to be full-time, you get benefits and a pension. However, if you're an adjunct and your fine art career is taking off, you can drop out of academia and then dip back in. But to do this, keep the lines of communication open and your foot in the door.
People skills and knowing your legal rights are important when teaching. Join the Union! Learn to work the system because you must protect yourself. The great thing about academia is that you can get health insurance and a pension after you are vested. To maximize the benefits, be informed. Read all your emails and be proactive! You need to know all the rules wherever you are working. You need an MFA if you want to teach in higher education and for K-12 you need an art education degree.
Art Preparator: Another day job is being an art preparator/handler. All the well-known and financially successful artists have a staff and one of the positions is an art preparator/handler. Also, you can work for an art packing firm and be an art handler. You don't even need an advanced degree for these jobs but it helps. It’s great because you're in the industry and you're meeting people, and if employed full-time, you may get a health plan and 401K. The downside is you don't get as much time off as teaching. However, you can more easily dip in and out of this work. With experience you can be a freelance art preparators instead of working for a company like Crozier Fine Arts and Cookes Crating. You can also be an art preparator at one of the museums in town or one of the blue chip galleries. It’s a great way to get into the art world and to learn more about that world.
Art Fabrication: A canvas/panel making business is another way to make money or working at a framing shop. Learn a craft and use it.
Artist assistant: Artist assistants can make a good living, but that’s a “who you know situation” in terms of getting a position. If this job is with a major artist, it can have benefits like health insurance, pension, etc. Additionally, you get to see behind the scenes. You can learn a lot about the business side of the art world both locally and in the larger art world.
Another position is that of an art registrar, the person who manages the inventory., or a photographer. These positions could be at a museum, big gallery, or for a major artist.
To make a steady living to support or supplement your art practice, you're either going into teaching or into the business side of the art world. This also includes the film industry here in LA. You can also be an independent curator or art critic. These freelance jobs don't pay a ton of money, but the can give you additional connections and exposure.
