Where you crashed matters as much as how hard. A diminished value claim in one state is a routine payout; in another it’s a fight your own insurer will refuse outright. This guide covers what Texas drivers can file, then does the same for Florida, California, North Carolina, and Georgia, plus how GEICO and Progressive tend to handle each. The rules are not interchangeable, and knowing yours is the difference between a check and a denial.
Diminished value is what a vehicle loses at resale after it’s been in an accident and repaired. Even with flawless bodywork, the crash shows up on Carfax and AutoCheck, and buyers pay less for a car with history. Recovering that gap between what it was worth before and what it’s worth now is the whole point.
Why your state decides who pays
Your state decides two things: whether you can bill your own insurer, and how long you have to file. Most states only let you recover the loss from the at-fault driver’s insurer, the third-party route. Collecting from your own policy, a first-party filing, is rarely allowed. Georgia is the standout exception that forces first-party payment.
- First-party route: you collect from your own insurer. Available in Georgia; almost nowhere else for a repairable car.
- Third-party route: you collect from the at-fault driver’s insurer. This is the standard path in Texas, Florida, California, and North Carolina.
- The deadline: set by each state’s property-damage statute of limitations, ranging from two to four years.
One number runs through every state: the 17c formula. It’s the calculation insurers start from, named after exhibit 17c in a Georgia lawsuit. It caps the loss at 10% of the car’s pre-accident worth, then trims it for damage severity and mileage. Appraisers who look at real resale data usually land higher.
Estimate yours with the calculator below. It runs the 17c formula insurers start from next to the market-based loss independent appraisers find, so you can see the gap worth disputing.

See what your car is worth now that it has a crash on its record, two ways. First, the 17c formula insurers use to price diminished value claims. Second, the market-based range appraisers actually find once the accident hits the vehicle history report. The gap between them is your negotiation.
Educational estimate, not an appraisal or legal advice. The 17c formula (10% base cap × damage modifier × mileage modifier) comes from the Mabry v. State Farm settlement in Georgia and is the method most insurers use, but no state's law requires it. The market range reflects the appraiser convention that accident history typically costs 10 to 20 percent of pre-accident value for meaningful damage, scaled here by severity. Diminished value is claimed against the at-fault driver's insurer; you generally cannot claim it for an accident you caused, Michigan bars these claims outright (a small mini-tort recovery applies instead), leased vehicles route through the leasing company, and Georgia uniquely requires insurers to assess it proactively. Statutes of limitations vary by state. For a vehicle worth $20,000 or more, or any structural damage, a certified independent appraisal usually pays for itself; support the claim with your history report, repair invoice, and comparable listings for clean-history and crash-history cars.
The car value after accident calculator shows both figures side by side: the formula payout an adjuster is likely to quote, and the realistic resale hit for meaningful damage, which typically runs 10% to 20% of pre-accident worth. That spread is your negotiating room.
How the five states compare, at a glance
Here’s how the five states stack up on the two questions that decide your payout: can you go after your own insurer, and how long do you have.
| State | First-party DV allowed? | Deadline to file (property damage) | Notable rule |
|---|---|---|---|
| Texas | No (third-party only) | 2 years | Adjusters lean hard on the 17c formula |
| Florida | No (third-party only) | 2 years (since 2023 reform) | No-fault state; DV sits outside PIP |
| California | Limited | 3 years | DV recognized as property damage |
| North Carolina | No (third-party only) | 3 years | Appraisal clause plus pure contributory negligence |
| Georgia | Yes | 4 years | Mabry v. State Farm mandates first-party payment |
Diminished value claim Texas rules
Texas recognizes third-party DV claims, so you file against the at-fault driver’s insurer, not your own. First-party recovery is rarely available because standard Texas auto policies limit the insurer’s duty to repairing the car, not restoring its market worth. The deadline is two years from the accident under the Texas property-damage statute of limitations.
Practical note: Texas adjusters lean hard on the 17c formula, which caps the loss at 10% of pre-accident worth and then knocks it down for mileage. Independent appraisals routinely land higher, so treat a formula-only offer as a starting point, not the ceiling. Get your own valuation before you respond.
Florida rules
Florida allows third-party DV claims against the at-fault carrier, and first-party recovery is generally not supported by standard policy language. The bigger recent change is the deadline. Florida’s 2023 tort reform cut the negligence statute of limitations from four years to two for accidents on or after March 24, 2023, so the Florida filing now has a tighter window than it used to.
Florida is a no-fault state for injuries, but that only covers medical bills through PIP. Property damage and the resale loss sit outside PIP entirely and go straight to the at-fault driver’s property-damage liability coverage. Don’t let an adjuster fold that shortfall into the no-fault conversation; it’s a separate recovery.
California rules
In California, this is in practice a third-party matter. California courts treat the loss as a component of property damage, and the deadline is three years from the accident under Code of Civil Procedure section 338. First-party recovery is limited: state regulations require insurers to consider the shortfall on total losses, but for a repairable car it’s pursued against the at-fault party.
Keep every repair invoice and commission an independent appraisal. California adjusters will negotiate, but they rarely volunteer the full number, and a documented appraisal based on comparable sales is what moves an offer.
North Carolina rules
North Carolina is one of the more claimant-friendly states for DV recovery on the third-party side, with a three-year deadline. NC auto policies include an appraisal clause that lets you and the insurer each hire an appraiser and, if they disagree, bring in a neutral umpire. That process gives you real leverage most states don’t offer.
Watch the fault rule. North Carolina uses pure contributory negligence, so if you’re found even 1% at fault, you can lose the payout entirely. Establish the other driver’s full fault, with the police report and any witness statements, before you push a demand NC adjusters will take seriously.
Georgia rules
Georgia is the one state where your own insurer owes you diminished value. The 2001 Georgia Supreme Court case Mabry v. State Farm held that first-party policies must pay it, and it forced insurers to assess the loss proactively. That case is also where the 17c formula got its name, from exhibit 17c in the settlement.
A Georgia filing can be first-party or third-party, and the deadline is four years under O.C.G.A. section 9-3-32, the longest window of the five states. Georgia insurers are supposed to evaluate the loss without you asking, but in practice you should still submit your own appraisal. The proactive-assessment rule sets a floor, not a fair number.
How GEICO and Progressive handle diminished value
Both GEICO and Progressive pay diminished value where the law requires it, and both start low. With GEICO, expect the 17c formula as the opening offer, especially in Georgia where first-party payment is mandatory. Progressive follows the same pattern: the carrier acknowledges the loss, applies the formula, and negotiates from there.
For third-party filings against either insurer in Texas, Florida, California, or North Carolina, you’re the one who has to prove the number. Here’s what actually moves these carriers:
- An independent appraisal from a licensed appraiser, not your own estimate.
- Documented pre-accident market value from KBB, Edmunds, or NADA.
- The full repair invoice showing structural work, which drives resale loss.
- Comparable sales showing what similar cars with clean histories fetch.
In my experience the single biggest lever is a credible independent appraisal. Adjusters discount a car owner’s own estimate on sight, but they have a much harder time dismissing a licensed appraiser’s report that documents real comparable sales. The formula worksheet is the floor; the appraisal is what gets you past it.
Filing your diminished value claim
Start by pinning down your pre-accident market value and running the numbers, because every diminished value claim Texas, Florida, California, North Carolina, and Georgia drivers file rises or falls on that figure. Use the car value after accident calculator to see the 17c payout next to the market-based loss, gather your appraisal and repair records, then send a written demand to the correct insurer for your state within the deadline. If you’re still fuzzy on the basics, the step-by-step walkthrough on what a diminished value claim is covers how to file from scratch.
Frequently asked questions
Can I file a diminished value claim with my own insurance?
Usually only in Georgia. The Mabry v. State Farm ruling requires Georgia first-party insurers to pay diminished value. In Texas, Florida, California, and most other states you file against the at-fault driver’s insurer, not your own.
How long do I have to file a diminished value claim in Texas?
Two years from the accident date, matching the Texas property-damage statute of limitations. Florida is now two years for accidents after March 2023, while California and North Carolina allow three years and Georgia allows four.
How do insurers calculate diminished value?
Most start with the 17c formula: 10% of pre-accident value as a cap, multiplied by a damage-severity factor and then a mileage factor. Independent appraisals based on comparable sales usually come out higher than the formula figure.
What is the 17c formula?
A calculation named after claim exhibit 17c in Mabry v. State Farm. It caps diminished value at 10% of the car’s pre-accident value, then reduces it for damage severity and mileage. Insurers use it as a starting offer, not a final number.
Does GEICO or Progressive pay diminished value?
Yes, where the law requires it. Both typically open with the 17c formula and negotiate from there. In Georgia the payment is mandatory on first-party claims; in other states you generally pursue them as third-party claims against the at-fault driver’s policy.
