How to use the warranty claim deadline calculator
Pick the type of claim, enter the delivery or substantial completion date and, where the option requires it, the date the defect was discovered. The tool returns the date the clock starts, the period applied, the claim deadline, days remaining and the controlling rule.
Legal basis (September 2026) — For the sale of goods, UCC 2-725(1) as adopted in nearly every state gives four years from tender of delivery, and 2-725(2) shifts the start to discovery only where a warranty explicitly extends to future performance. Construction defect claims are governed by state law: an ordinary limitations period, usually measured from discovery and commonly 2 to 6 years, plus a statute of repose measured from substantial completion and commonly 6 to 12 years. Because those two figures are state specific, the period field is editable. Check your state statute.
Written warranties on consumer products are separately regulated by the Magnuson-Moss Warranty Act, 15 U.S.C. 2301 and following, which governs what the warranty must say rather than how long you have to sue.

Frequently asked questions
UCC 2-725(1) sets four years from the date the breach occurs, and the breach occurs on tender of delivery regardless of when the buyer learns of the defect. Parties may agree to shorten the period to not less than one year, but not lengthen it.
UCC 2-725(2) makes an exception where a warranty explicitly extends to future performance of the goods. In that case the four years run from when the breach is or should have been discovered, not from delivery.
For construction, most states add a repose period running from substantial completion, commonly 6 to 12 years, which can bar a claim even if the defect was never discoverable in time. It runs alongside the ordinary limitations period, and both must be checked.
