Just as a rule of thumb, a new artist can figure their time out (materials are nearly inconsequential) at those of a beginning commercial artist.
$35.00 an hour is what I tell new artists to use. But this is only a guideline as abstract art can be created in much less time than, say, a photo realistic painting. Then, if it takes 20 hours to complete a painting, that is likely it too expensive for salability (depending a lot on the demographics). I came up with this basic price point based on size for new art:
16 x 20 $1,500.
18 x 14 $2,000.
24 x 30 $2,500.
30 x 40 $3,000.
These are base prices so one has to work with a gallery owner or director to come up with an intrinsic value based on the perceived quality of the work. I've priced a 24 x 30 as high as $4,500. Then again, I've priced a huge 5' x 8' abstract painting at the same price. Again, materials are not a consequence. If you are working with a gallery who doesn't know how to price artwork in their demography (another factor), look elsewhere.
As to insurance, it's almost a moot point -- an insurance company will insure it but will they pay what you've priced them at with little or no sales record? No. And actually, galleries are required to have a theft and fire policy that covers the work unless you sign a disclaimer. You could have it listed as "off site" part of your household insurance but for replacement cost only (you might get away with half of the sales price or $17.50 and hour to place a value on each work).
As to household art, most insurance companies will write policies based on original invoice values as household furnishings up to $50,000. Otherwise, one needs a rider and an independent appraisal (insurance companies and the IRS will not accept gallery or auction appraisals). The American Society of Appraisers members will charge one from $300. on up for one to four pieces. You have to get an estimate from the appraiser they recommend in your area. I don't have their contact numbers at home right now but you can E mail me at
[email protected] for that information. BTW, the appraiser will not authenticate a work but only appraise it with the qualification "if this is authentic." Authentication is another unfortunate bugaboo of buying art. There's plenty of phony stuff out there and auctions will not stand behind authentication -- it's in the fine print. One has to know art thoroughly to play the game.
BTW, in New York galleries you might find all those prices doubling! That's demographics!
