Written by attorneys · grounded in primary & secondary sources — see below
Damages awarded to a buyer for a seller's breach of warranty after acceptance of goods. The amount equals the difference at the time and place of acceptance between the value of the goods as delivered and the value they would have possessed if they had conformed to the warranty, unless special circumstances demonstrate that proximate damages differ in amount.

Defective Servers Trigger Value Differential
Harbor Logic purchased servers from Star Networks after seeing advertisements promising reliable performance with one thousand concurrent users. The buyer accepted the servers at the seller's facility following only basic power-on tests. Market evidence later showed that servers limited to five hundred users sold for substantially less than the contract price at the time and place of acceptance. Harbor Logic recovered the difference between the servers' actual value and their warranted value under the governing damages rule.
Surgical Warranty Produces Expectation Loss
A patient contracted with a surgeon for an operation that the doctor warranted would produce a good hand. The procedure left the hand in worse condition than before. The court measured damages by the difference between the value of the hand as it existed after the operation and the value it would have possessed if the warranty had been fulfilled, placing the patient in the position promised by the contract.

Common questions
Frequently Asked
4
When does the special circumstances exception permit a measure of warranty damages other than the standard value differential?+
The exception applies when facts show that the buyer's actual proximate loss differs from the ordinary difference in value at acceptance. Courts examine whether the defect was latent, whether the buyer provided notice of special needs, and whether later events demonstrate harm beyond the market value gap at the moment of acceptance.

How do warranty damages under UCC 2-714(2) differ from consequential damages under 2-714(3)?+
The value-differential formula in subsection (2) supplies the primary measure focused on the goods themselves at acceptance. Subsection (3) separately authorizes incidental and consequential damages in a proper case, but only after the base measure is applied or when special circumstances justify an alternative calculation.
Supporting sources
Does buyer acceptance of nonconforming goods bar all warranty damages claims?+
Acceptance precludes rejection of the goods but does not impair the buyer's right to recover damages for nonconformity. The buyer may still pursue the value-differential measure plus any available incidental or consequential damages after proper notice.
Supporting sources
What evidence establishes the value of goods as warranted versus as accepted?+
Market data for comparable goods at the time and place of acceptance supplies the most direct proof. When comparable sales exist, courts use those prices to calculate the differential without requiring proof of the buyer's later actual losses.
