01 · The work

Physical dimensions set the structure of the value. Measure the artwork itself, without the frame, in centimetres.

Estimate updated: $1,850.

02 · The credentials

How well known is the artist? Count what you can verify — leave the rest at zero. Each entry raises the multiplier applied to the size.

How this price is calculated

Height × Width (in.) × cofactor

Low · 48%overall confidence

No credentials recorded, so the cofactor sits at its baseline and the estimate rests on dimensions alone.

01 · Cofactor contributions

No credentials recorded yet, so the cofactor sits at its 1.5 baseline.

Credential score 0 → cofactor: 1.5 + 2.4 × 0^0.5 = 1.5

03 · Final estimate

1,240 in² × 1.5 (cofactor) × 1 (medium) = $1,850

Negotiation range: $1,500 to $2,400 (0.8×–1.3×), rounded to the nearest $50.

04 · Assumptions behind each factor

Low · 48%

Height

High · 95%

Dimensions are supplied directly, so only the unit conversion is assumed.

  • Measurement is the unframed support size, height before width.

Width

High · 95%

Dimensions are supplied directly, so only the unit conversion is assumed.

  • Depth is ignored — pricing uses the two largest faces only.

Surface area

Medium · 65%

Linear area pricing is the museum-style convention, but very large works often discount.

  • Price per square inch is constant — no premium for small works or discount for very large ones.

Medium factor

Medium · 60%

A single fixed multiplier stands in for the whole medium category.

  • Materials, technique, series and condition are not priced separately.
  • All painting works share the same multiplier.

Condition factor

Low · 45%

No condition given, so a very good, market-standard state is assumed.

  • Condition is judged from the whole work, not localised damage.
  • Restoration cost is not deducted separately from the estimate.

Applies to the whole estimate

  • All figures are primary-market asking prices in USD, before taxes, shipping and gallery commission.
  • The estimate is a pricing structure, not a formal appraisal or an auction forecast.
  • Auction records are shown for reference only and never enter the cofactor.
  • Condition, provenance, date of execution and demand for a specific series are not modelled.
  • The negotiation range assumes a 0.8× to 1.3× band around the calculated price.
