A buyer's premium is the fee an auction house adds on top of the winning hammer price and charges entirely to the buyer, separate from whatever commission the house negotiates with the seller. At Sotheby's, that fee now runs as high as 28 percent on the first $2 million of a New York hammer price, under a new schedule the house put into effect on February 13, 2026, according to Sotheby's and The Art Newspaper.
What Exactly Is a Buyer's Premium, and Who Pays It?
The buyer's premium is a percentage fee, calculated on the hammer price of each lot, that the winning bidder pays in addition to that hammer price. Sotheby's own guidance is direct on the point: "a buyer's premium is added to the hammer price of each lot offered and is payable by the buyer." It is not split with the consignor and it is not the same line item as the seller's commission, which the house negotiates privately and does not publish.
For a collector, the premium is the gap between what a lot "sold for" in headline coverage — which typically means hammer price plus premium — and what actually changed hands on the rostrum. A $1 million hammer price with a 28 percent premium becomes a $1.28 million invoice before local taxes or artist resale royalties, which Sotheby's notes are calculated separately.
How Much Is Sotheby's Buyer's Premium in 2026?
As of the February 13, 2026 schedule, Sotheby's charges 28 percent on hammer prices up to $2 million in New York, 22 percent on the portion between $2 million and $8 million, and 15 percent on any amount above $8 million, according to Sotheby's official guidance. The same tiered structure applies in other sale currencies, with the thresholds adjusted to roughly €1.75 million and €7 million in Paris, Cologne and Milan, and to £1.5 million and £6 million in London, per the house and The Art Newspaper's reporting on the change.
| Hammer price tier (New York) | Buyer's premium rate |
|---|---|
| Up to $2,000,000 | 28% |
| $2,000,001 – $8,000,000 | 22% |
| Above $8,000,000 | 15% |
Sotheby's carves out one further exception: in its Global Wines & Spirits sales, the house applies a flat 24 percent premium on every hammer price, plus a separate 1 percent "overhead premium," rather than the tiered structure used for fine art and other categories.
Why Do Buyer's Premiums Use Tiers That Fall as the Price Rises?
The declining-rate structure — a higher percentage on lower hammer prices, a lower percentage above $8 million — is now standard across the major auction houses, and it functions as a volume discount for the biggest spenders. According to The Art Newspaper, this reflects a broader recalibration in which "auction houses are carefully balancing much needed fee revenue with compelling deals for both buyers and sellers," with lower-priced lots remaining "relatively in demand even amid a wider market downturn."
Before the February 2026 change, Sotheby's had applied its 27 percent top rate starting at hammer prices of $1 million; the new schedule instead raises that top rate to 28 percent and extends it up to $2 million, according to The Art Newspaper's account of the prior schedule. In practical terms, a lot hammering just above $1 million now carries a heavier premium than it would have under the old tiers, even though the top-end rate above $8 million is unchanged at 15 percent.
How Does Sotheby's New Schedule Compare With Christie's?
Christie's revised its own premium schedule in September 2025, several months ahead of Sotheby's latest move. Under that schedule, as reported by The Art Newspaper, Christie's charges 27 percent up to $1.5 million (or £1 million), 22 percent on the tier between $1.5 million and $8 million (£1 million and £6 million), and 15 percent above $8 million (£6 million) — a structure similar in shape to Sotheby's but with a lower entry-tier rate and a different threshold for where that rate starts to step down.
The two houses' premium schedules rarely stay identical for long. Sotheby's abandoned a flat-fee experiment less than a year before the February 2026 revision because, according to comments attributed to chief executive Charles Stewart and reported by The Art Newspaper, the flat structure "proved less attractive to potential sellers." The reversal underscores how directly premium design is tied to competition for consignments, not simply to what buyers will tolerate.
Why Did Sotheby's Raise Rates Now, in a Recalibrating Market?
The timing lines up with a market that grew in aggregate in 2025 even as it remained selective. The global art market reached $59.6 billion in sales in 2025, a 4 percent increase over the prior year, according to the Art Basel and UBS Global Art Market Report 2026, compiled by the research firm Arts Economics. Public auction sales were the strongest-performing segment, rising 9 percent year-over-year to $20.7 billion, while the dealer sector grew a more modest 2 percent, to $34.8 billion, and private sales fell 5 percent, to $4.2 billion.
The strength was concentrated at the top. Sales above $1 million rose 21 percent year-over-year, and sales above $10 million surged 30 percent, per the same report. That pattern — growth clustered in higher price bands even as the broader market stayed cautious — helps explain a premium schedule that keeps its top-end rate flat above $8 million while raising the rate on the tier just below $2 million, where Arts Economics found demand had held up "even amid a wider market downturn," in The Art Newspaper's phrasing. The United States remained the largest single market by a wide margin, accounting for 44 percent of global sales, or $26 billion, with the United Kingdom second at 18 percent and China third at 14 percent, according to the report.
How Does the Premium Change What a Winning Bid Actually Costs?
For a collector budgeting a bid, the premium is not an afterthought — it is often the largest single addition to the final invoice besides the hammer price itself. On a $1.5 million hammer price at Sotheby's New York under the current schedule, the 28 percent rate on the full amount (since $1.5 million falls under the $2 million threshold) adds $420,000, bringing the total before tax to $1.92 million. On a $5 million hammer price, the tiered structure applies 28 percent to the first $2 million ($560,000) and 22 percent to the remaining $3 million ($660,000), for a combined premium of $1.22 million on top of the hammer price.
None of this includes state and local sales tax, import or export duties on works crossing borders, or the artist resale royalties that Sotheby's notes are calculated separately in jurisdictions where they apply. Collectors budgeting for a specific lot are generally advised, in Sotheby's own guidance, to consult the house's published Conditions of Business for Buyers for the precise, current figures rather than rely on prior-year rates.
Frequently Asked Questions
- Does the seller pay the buyer's premium too? No. Sotheby's states the premium is payable by the buyer and is calculated on top of the hammer price; the seller's commission is a separate, privately negotiated fee that the house does not publish.
- Is the buyer's premium the same at every Sotheby's sale location? No. The percentage tiers are consistent in shape but the dollar or currency thresholds vary by sale currency — for example, roughly €1.75 million and €7 million in Paris, Cologne and Milan, versus $2 million and $8 million in New York, according to Sotheby's own guidance.
- Why did Sotheby's raise its premium in February 2026 instead of lowering it? The house has not published a single stated reason in the sources reviewed here; The Art Newspaper frames the move as part of a wider recalibration in which auction houses are balancing fee revenue against competitive pricing on lower-value lots, which stayed comparatively resilient even as the broader market cooled.
- Does Christie's charge the same premium as Sotheby's? Not exactly. As of Christie's September 2025 update, reported by The Art Newspaper, its entry-tier rate was 27 percent, one point below Sotheby's current 28 percent, though both houses' top-tier rate above $8 million sits at 15 percent.
