17c Diminished Value Calculator

The 17c formula is the industry-standard starting point used by State Farm, GEICO, and most adjusters. Real recoveries are usually higher — this gives you the insurer's anchor.

Frequently asked

What is a diminished value claim?

Diminished value (DV) is the loss in resale value a vehicle suffers after a reported accident, even when fully repaired. A buyer will pay less for a car with an accident on Carfax. You can recover that gap from the at-fault driver's insurer (third-party DV), and in a handful of states, from your own insurer (first-party DV).

How much is a diminished value claim worth?

Most claims fall between $1,500 and $6,500. The 17c formula caps DV at 10% of pre-loss ACV, but real market-data appraisals usually exceed that. A 3-year-old vehicle with structural damage routinely loses 18–25% of value.

Which states allow first-party diminished value claims?

Georgia (Mabry v. State Farm), Washington (Moeller v. Farmers), Massachusetts (Bulletin 2016-04), Kansas, and Kentucky have squarely affirmed first-party DV. Every other state allows third-party DV against the at-fault driver's insurer.

How long do I have to file a diminished value claim?

Statute of limitations varies by state — typically 2–6 years for property damage. Florida and Texas are 2 years; California and Colorado are 3 years; Illinois is 5 years. File early; insurers stall.

Is the 17c formula accurate?

No. 17c was created by State Farm in a Georgia consent decree and has no statistical basis. Adjusters use it as an opening anchor. An independent market-data appraisal (comparing your VIN's pre-loss vs post-loss comps) almost always recovers more.
