Two paintings the same size hang side by side. One sells for $200, the other for $200,000. Same canvas, same paint — wildly different value. Art pricing feels mysterious, but appraisers actually weigh five concrete factors. Learn them and you can estimate roughly where a painting lands before you ever call an expert.
The five factors that set the price
1. The artist (the biggest lever by far)
Who painted it matters more than anything else. A work by a recognized, collected artist can be worth orders of magnitude more than a technically similar piece by an unknown. Establishing the artist — through signature, style, and provenance — is the first and most valuable step.
2. Authenticity
Is it genuinely by that artist? An attributed or authenticated work is worth a multiple of a "in the style of" piece. Doubt destroys value; proof creates it. This is why documentation matters so much.
3. Provenance
The documented ownership history. A clear chain — gallery receipts, exhibition records, catalog listings — both proves authenticity and adds prestige. A painting that hung in a famous collection or show is worth more than an identical one with no paper trail.
4. Condition
Cracking, fading, tears, water damage, and heavy restoration all cut value. Original, well-preserved condition commands a premium. Note: amateur "cleaning" or restoration can destroy value — never DIY a potentially valuable piece.
5. Demand, subject, and size
Even for the same artist, some subjects and periods are more sought-after. Desirable imagery, a good display size, and current market taste all move the number. Rarity matters too — a scarce work from a prolific artist, or any work from a rare one, climbs.
Value isn’t about how "good" a painting looks. It’s about who made it, whether you can prove it, and how many people want it right now.
Estimate your painting’s value range
Set the sliders to match your piece for a rough, illustrative range. This is a thinking tool, not an appraisal — but it shows how dramatically each factor swings the result.
A solid mid-market piece. Comparable auction sales will sharpen this estimate.
Illustrative only. A real valuation needs a qualified appraiser and, ideally, authentication.
How to find out what your painting is worth, step by step
- Rule out a print. Many framed “paintings” are reproductions. Check the surface under a 10× loupe and a low, raking light before anything else — how to tell an original painting from a print. A mass-produced print is priced as décor, not as art; the steps below are for originals and hand-signed editions.
- Identify the artist and gather the paperwork. Read the signature on the front and back (how to read an artist’s signature), or work from labels, stamps and style if there isn’t one (identifying an unsigned painting). Keep every receipt, letter and old photo — that is your provenance.
- Place it in time. The canvas, stretcher and style narrow the date (how to date a painting). An artist’s early, prime and late works can sell very differently.
- Look up what comparable works actually sold for. Same artist, same medium, similar size, subject and period. Use prices that were paid, not asking prices.
- Ask for a free auction estimate if the comparables suggest real money.
- Pay for a written appraisal when you need a figure on paper — insurance, an estate, a donation, dividing property.
Where to look up what similar paintings sold for
An auction result is the closest thing art has to a public price tag: a real sale, on a known date, usually with a photo and the dimensions. Look for several sales of comparable works, not one record.
| Where | What you see | Cost | Best for |
|---|---|---|---|
| LiveAuctioneers price results | Past results from the auction houses that sell on the platform | Free — LiveAuctioneers calls it a free research tool; you need an account | Regional artists, decorative and mid-market works |
| artnet Price Database | International fine-art auction results | Paid subscription | Artists with an established auction record |
| Christie’s or Sotheby’s online estimate | A specialist’s likely selling range, from your photos | Free | Works that could sell at that house — both only estimate what they could take for sale |
| eBay sold listings (“Sold items” filter) | What similar unsigned or decorative pieces really sold for | Free | Works too modest for auction databases |
Two habits keep the comparison honest. Compare like with like: an oil on canvas is not priced like a watercolor, a drawing or a print by the same name. And check what a “price” includes — an auction result may be the hammer price or the price with the buyer’s premium added, and the seller receives less than either once the commission is taken.
Free estimate or paid appraisal?
| Auction estimate | Formal appraisal | |
|---|---|---|
| Who | An auction-house specialist | An independent appraiser — for paintings, look for membership of the American Society of Appraisers, the Appraisers Association of America or the International Society of Appraisers |
| Cost | Free | An hourly or flat fee |
| What you get | A likely selling range, if the house wants to sell it | A written report for a stated purpose and a stated type of value |
| Use it for | Deciding whether and where to sell | Insurance, estates, donations, dividing property |
Two things to know before you pay anyone. First, the fee should not depend on the value. A percentage of the appraised value gives the appraiser a reason to aim high, and for a US tax donation the rule is explicit: an appraisal whose fee is based to any extent on the appraised value is not a qualified appraisal.
Second, “value” has more than one meaning. Fair market value is the price a willing buyer and a willing seller would agree on, neither forced to act and both reasonably informed — the IRS standard for donations and estates. An insurance value is what it would cost to replace the work, and the IRS is clear that an insured value is not fair market value. Ask which one you are paying for. If you plan to donate a painting in the US and claim more than $5,000, you need a qualified appraisal and Form 8283.
Start with a fast ID. Art Scan: Painting Identifier identifies the artwork and artist from a photo — the crucial first step in any valuation — and explains the context around it. Use it to get oriented, then bring real candidates to an appraiser.
The takeaway
A painting’s worth comes down to artist, authenticity, provenance, condition, and demand. Rule out a print, nail down who made it and whether you can prove it, and check what comparable works actually sold for. Start with a quick identification, use a free auction estimate to see whether there is real money in it, and pay an appraiser a flat or hourly fee — never a share of the value — when you need the number on paper.
At a glance
| Factor | Raises value | Lowers value |
|---|---|---|
| Artist | Established market and auction record | Unknown or decorative painter |
| Authenticity | Catalogue raisonné, specialist opinion | “Attributed to”, “circle of”, “after” |
| Provenance | Unbroken, documented ownership | Gaps, especially 1933–1945 |
| Condition | Original, stable surface | Heavy retouching, tears, overpaint on faces |
| Demand, subject, size | Signature subject, prime period | Unfashionable subject, awkward size |
Frequently asked questions
How can I find out what my painting is worth for free?
Identify the artist, then look up what comparable works actually sold for — LiveAuctioneers’ price results are free with an account, and eBay’s “Sold items” filter covers modest pieces. If the results suggest real money, send photos to an auction house: Christie’s and Sotheby’s both give free online estimates for works they could sell.
How much does it cost to get a painting appraised?
An auction estimate is free. A formal written appraisal is paid, by the hour or as a flat fee. Be wary of an appraiser who asks for a percentage of the value — and for a US tax donation, a fee based on the appraised value disqualifies the appraisal.
What is the difference between an auction estimate and an appraisal?
An auction estimate is a house’s guess at a likely selling range, meant to attract bidders. An appraisal is a formal written valuation for a stated purpose — insurance, fair market value or donation — by an independent appraiser.
Is an old painting always valuable?
No. Age alone adds little; many 19th-century paintings sell for modest sums. Artist, quality and condition matter far more.
Does a signature make a painting worth more?
Only if it is the signature of an artist with a market, and it is genuine. Signatures are easy to add; specialists judge the whole work.
