Allstate does pay diminished value when an Allstate driver hit you, usually up to that driver's coverage limits. If you're claiming on your own Allstate policy, courts have sided with Allstate when it said no.
Diminished value means the drop in what a car can sell for once it carries an accident history, even when repairs were done right. Allstate's own site accepts that this loss exists. What decides whether Allstate actually pays comes down mainly to fault and which policy the claim falls under.
Allstate's Own Take on Lost Value
Allstate's guide to car depreciation explains that a vehicle with a crash behind it sells for less than an identical one that was never hit, no matter how well it was fixed. That guide also points to inherent diminished value as the type seen most often. This is the loss that comes purely from buyers knowing the car was once damaged, even if nothing remains wrong with it.
The guide covers the concept broadly. It stays silent on when Allstate itself would cover this kind of loss.
When an Allstate Driver Caused the Crash
Here you file a third-party claim, meaning you go through the other driver's insurance instead of your own. Allstate's third-party claims page explains that this type of claim is handled by the insurer covering the driver who caused the accident. When Allstate insures that driver, Allstate becomes the company you work with.
That page also notes that what gets paid depends on the at-fault driver's coverage limits. If limits are low and repairs cost a lot, little or nothing may remain to cover lost value.
A study prepared for the Connecticut legislature concluded that most courts permit diminished value claims brought against the driver responsible. This is the setting where getting Allstate to pay for lost value is most realistic.

Will Allstate Pay Lost Value to Its Own Policyholders?
Generally no. Allstate policies can contain language that excludes any decrease in a vehicle's value, and Allstate has relied on that language in court and won. Your own policy booklet's exact wording controls your situation, so it pays to search for any clause mentioning a decrease in value.
If you live in Georgia, there's one extra protection. A Liberty Mutual notice says Georgia's insurance commissioner told every insurer to check whether a claim involves lost value. That isn't a promise of payment, but it means the question should at least be looked at.
Watkins v. Allstate in Mississippi
After a crash, Kenan Watkins sought diminished value through his own Allstate policy. The Fifth Circuit decision records that Allstate refused the claim, pointing to a policy exclusion covering any decrease in value. Watkins countered that this exclusion violated the state's uninsured motorist statute.
The federal appeals court handed down its ruling on January 12, 2024, siding with Allstate and holding that Mississippi law permits the exclusion.
Sims v. Allstate: The Illinois Class Action
Allstate customers in Illinois filed a class action, meaning a single suit representing a large group of people sharing the same grievance. PropertyCasualty360 reported the claim sought $300 million or more for 387,000 class members.
The court record indicates Allstate had covered the cost of repairing the vehicles but had not covered diminished value. The jury sided with Allstate, and the Illinois Appellate Court upheld that outcome in a ruling issued in 2006.
How Much Value Could Your Car Lose?
A typical place to start is the portion of value lost at each damage level. The market ranges below are percentages of the car's worth right before the accident.
| Type of damage | Typical share of value lost |
|---|---|
| Severe frame or structural damage | 15% to 30% |
| Heavy frame damage affecting many panels | 10% to 20% |
| Moderate frame damage affecting several panels | 5% to 12% |
| Light frame damage affecting a few panels | 3% to 8% |
| Only panels or bumpers, with no structural harm | 2% to 5% |

You may also see a formula called 17c. It usually gives a lower number because it starts from 10% of the car's value and then cuts that amount for lighter damage and for higher mileage. Once a car reaches 100,000 miles or beyond, it pays nothing.
Allstate does not share how it figures out diminished value. According to Carfax, many insurance companies rely on the 17c formula. You are allowed to push back on any offer. Ask the adjuster in writing to explain how they got the amount. Then respond with your own estimate or an appraisal.
As an example, picture a car valued at $25,000 pre-crash, with 30,000 miles and moderate frame damage affecting several panels. The market range comes to $1,250 to $3,000, while 17c gives $1,000. With 100,000 miles or more on that same car, 17c falls to $0, while the market range stays between $1,250 and $3,000.
Is It Worth Claiming From Allstate?
Usually, yes, if the car is fairly new, has low miles, and had serious damage, like frame repair. The frame is the metal skeleton of the car. It also helps if the Allstate driver's insurance still has money left after paying the repair bill.
Filing a claim may not be worth your time when:
- the damage was minor, like a bumper or a dent, so the loss might only be a few hundred dollars
- the car is older and has 100,000 miles or more
- you are filing under your own Allstate policy, and that policy does not cover any drop in value
- an appraisal, which usually costs $300 to $600, would eat up most of what you could recover
How to File a Diminished Value Claim With Allstate
This kind of claim stands or falls on evidence. The usual sequence goes like this:
- Put your diminished value request in writing on the existing claim.
- Provide the repair estimate together with the final invoice, so the insurer can judge how severe the damage was.
- Attach photos of the damage from before the repair, since they capture what the completed work now hides.
- Add a vehicle history report, because it records the accident that future buyers will see.
- Back up your number with an estimate or appraisal report, so the amount rests on more than your own say-so.
- Request a written answer within 30 days, giving you a firm date by which to expect a response.
