# Thread: Ack! Math... How to calculate in gallery commission?

1. ## Ack! Math... How to calculate in gallery commission?

Ugh... I hate math, but you have to know it. Here's a math problem for all of you so inclined.

You know a gallery will take a % of commission from each painting sold. Say 40%. Now, you know how much you want for a piece... say, \$500.00. Now, how do you figure out how much the piece will end up being in the gallery?

Anyone know a good (step-by-step, make it good and simple) way to figure this out on a calculator?

Many thanks!

3. 500 times .4 equales 200. So 200 is 40% of 500.

If you want to know 50% do 500 times .5 equales 250. 250 is 50% of 500.

20% you times by .2
30% you times by .3
ect.

i think.

Didn't you ever take algebra?

6/10x=500
x=500*10/6
x=833.33

6/10=gallery commision percentage as a fraction
500=desired profit

i think cenobite wants this...

what to charge - (40% of what to charge) = \$500

which is something like "what to charge = what cenobite wants divided by 0.6"

so... he puts the price at \$834. 40% of \$834, which is \$333.60 goes to gallery. Cenobite walks away with \$500 and 40 cents to buy some gum.

edit> i'd go with mike yamada's technique... more \$\$\$\$\$\$\$\$\$!!!!!!

6. Uhh...Machzero is right.

7. seriously?

what Faxtar writes is of course correct but doesn't apply here. just calculate back using the example of 40%:
200 = 40% of 500. (correct).
but 500+200=700. now go back and calculate that 40% comission:
700/100*40 = comission = 280.
700 - 280 = 420. not 500; oops...

again, in the example of 40% comission of the sale price you better do:
comission = 40/100 of sale price.

500 + 0.4 price = price
500 = 0.6 price
(1/0.6)*500 = price = 833 bucks.
calculate back:
833 - 40% of 833 = 833 - 333 = 500.

edit - hadn't seen machzero's post.

i did?

j/k...
you are close.
cenobite mentioned that the gallery would take 40%, but HE wanted \$500.
meaning his cut is actually the remaining 6/10 of x.
so,
6/10 x=500
x=500(10/6)
x=833.3

9. mechzero, tensai, and DS got it.
Of course, standard gallery commision is 50%, making the figuring really eazy.

10. I'd also add that, quite apparent in the example given, a nice round price for you does not always equal a nice round price for the customer and pricing a painting at \$833 is kinda awkward. In those cases, I'd just go ahead and round to 825 or 850 if i were you. Odd prices (generally prices that are not multiples of 25 at this price range) are sometimes distracting and tend to call attention to the very arbitrary nature of pricing paintings.

11. just to make life more complicated...I deal with about 12 Gallerys. all but on of them take 50%

Except overseas its price = what you want to recieve, times 2 (50%) plus VAT just to make things alittle worse.

but an easier figure is price you want to recieve. plus gallery Comission+ retail price

PM me if you need more info..I do do this for a living

Erm, or you could do this the easiest way of all.

Divide your desired price by the value: 1-({gallery percentage}/100)

Eg, you want \$500.00. Gallery commision = 40%

\$500 / (1 - {40%/100})

= \$833

14. \$500 / (1 - {40%/100})
are you sure that's the easiest way? because I think it's the exact same as Dan's except rewritten to confuse me. man, screw this math stuff, seriously

Of course its the same way, because its a generic calculation. Just this way, he only has to remember one single line of a calculation, and just plug in his two numbers. You don't need to know why it works, just that it does. And this one line is pretty easy to remember.

lots of gallerys determine their own commission. my buddy just sold a few pieces and the gallery took 50% and his agent took 15%, so he was left with shit. i would push for more than \$500 profit.

18. my buddy just sold a few pieces and the gallery took 50% and his agent took 15%, so he was left with shit.
your buddy should try working a better deal. was his agent in any way even connected with the gallery sales? I know some agents and galleries will demand their cut whether they were involved in the sale or not, but I also think of these as people to generally avoid doing business with

19. unless you have a contr act with the gallery..I see no point in agents unless they are actually working foryou in a big way. But the standard gallery commission for art work is 50% has been for years. I suppose you might be able to brokera better deal if you are really really good, but I wouldn't count on it. The only way ythe gallery gets a cut if they did not make the sale is if they have a contract for an exclusive in a particular area. otherwise you sales are your sales. Don't undercut your gallery prices though thas tacky and unprofessional.
