How to Price Art: Formulas, Costs, and Gallery Commission

Compare square-inch, linear-inch, and time-and-cost art pricing methods, calculate gallery commission, and calibrate rates from your own sales.

There is no universal formula that can appraise an original artwork. A useful pricing system does something narrower: it gives similar work a consistent starting point, covers the inputs you choose, and makes commissions or selling fees visible.

The free Art Pricing Calculator compares square-inch, linear-inch, and time-and-cost methods using your own rates. It also gross-ups a price so the amount you want to retain remains after a gallery or platform takes a percentage.

Start with evidence, not a generic rate table

NYFA's visual-artist pricing guide recommends researching artists whose work is genuinely comparable in medium, size, career stage, location, and sales context. Your own completed sales are even more direct evidence.

Build a small comparison set:

1. Record the artwork dimensions, medium, date, asking price, actual sale price, venue, and fees.
2. Separate the amount you retained from the buyer's total price.
3. Subtract direct costs such as canvas, framing, and paid shipping.
4. Convert the remaining artwork amount into a square-inch or linear-inch rate.
5. Compare several similar sales instead of calibrating your whole practice from one unusual piece.

Do not copy another artist's rate simply because the dimensions match. Reputation, collector demand, exhibition history, medium, condition, and market still differ.

Method 1: price per square inch

Square-inch pricing multiplies the artwork's area by a rate you establish:

Artwork amount = width × height × square-inch rate

For a 16×20-inch painting, the area is 320 square inches. If your own comparable sales support a $2.50 rate, the artwork amount is $800 before separately allocated materials, framing, overhead, or selling commission.

Artists Network demonstrates a square-inch workflow while warning that the rate must fit the artist's reputation and market. Because both width and height increase, this method makes large-work prices rise quickly.

Method 2: price per linear inch

Linear-inch pricing adds width and height before applying the rate:

Artwork amount = (width + height) × linear-inch rate

For a 16×20-inch painting, the linear measure is 36 inches. At a user-selected $20 rate, the artwork amount is $720 before other costs and fees.

Linear pricing grows more gradually than area pricing. That can make a size ladder easier to explain when your body of work ranges from small studies to large canvases. It is still a consistency formula, not a market valuation.

Method 3: time and cost

Artists without enough comparable sales can begin with measurable inputs:

Artist target = labor hours × hourly rate + materials + allocated overhead

ArtBusiness describes labor and materials as a practical starting point, especially without a long sales history, but says the result still needs a market comparison.

Track active working time consistently. Materials can include the support, paint, varnish, frame, hanging hardware, and packaging assigned to the piece. Overhead may include a reasonable share of studio rent, insurance, software, equipment, photography, and marketing, but the allocation method should remain consistent.

How to account for gallery commission

Do not add the commission percentage to the amount you want to retain. Gross it up:

Retail price = artist target ÷ (1 − commission rate)

If you want to retain $600 after a 40% commission:

• Remaining share: 1 − 0.40 = 0.60
• Retail price: $600 ÷ 0.60 = $1,000
• Commission: $400
• Artist retains: $600

NYFA notes that gallery commissions commonly take a material share of the selling price, but your signed agreement controls the actual percentage and covered services. The calculator accepts the percentage rather than assuming one.

Compare the methods without cherry-picking

Three methods can produce very different results for the same artwork. That difference is diagnostic:

Choose a repeatable method that fits your practice and sold work. Do not automatically pick the highest output for one piece and the lowest for another.

Keep a pricing record

For every offered work, retain:

• title, medium, dimensions, and completion date;
• formula and input rate used;
• direct costs and allocated overhead;
• public retail price and sales channel;
• commission, payment, and shipping fees;
• actual sale price, artist net, and sale date.

This record lets you measure sell-through, net margin, and effective rates over time. It also prevents accidental price conflicts across a studio sale, website, marketplace, and gallery.

What the calculator does not include

The Art Pricing Calculator does not estimate appraisal value, auction value, or insurance replacement value. It does not know the quality, provenance, condition, demand, career history, or market for a specific work.

Use it as a transparent worksheet. For appraisals, tax, insurance, contracts, or representation decisions, use the appropriate qualified professional and written agreement.
