Diminished Value Claim: Who Pays and the 17c Formula
By Plain Money Guide · Researched from official sources · Checked 2026-08-07 · Editorial standards
A perfect repair still leaves an accident on the record — that gap is what a diminished value claim pays for.
A diminished value claim goes to the at-fault driver's insurer, not yours, and the 17c formula most insurers use caps the payout at 10% of your car's pre-crash value.
That single sentence decides most of these claims before they start. If you caused the wreck, there is almost certainly no diminished value money for you anywhere. If someone else caused it, there probably is — but the number the adjuster hands you comes out of a 25-year-old formula with two multipliers that can quietly cut it to nothing. Here is how the math actually runs, and the three situations where people file a valid claim and still collect zero.

What diminished value actually compensates
Diminished value (DV) is the gap between what your car was worth the minute before the crash and what it is worth after a flawless repair. The repair itself is a separate claim. DV is the extra loss created by the accident showing up on a CarFax or AutoCheck report — buyers and dealers pay less for a car with a reported structural repair, even one done perfectly.
Three flavors get discussed, but only one is normally payable:
- Inherent diminished value — the stigma of a reported accident on an otherwise properly repaired car. This is the claim insurers pay.
- Repair-related diminished value — the shop did poor work: mismatched paint, panel gaps. That is a repair-quality dispute, not a DV claim.
- Immediate diminished value — the drop before any repair happens. Almost never paid, because the repair claim already covers it.
Who pays: your insurer or theirs
Third-party means you file against the at-fault driver's property damage liability coverage. This is the standard route and the one that works. You are not their customer, so there is no contract limiting you — you are a claimant asserting a property damage loss they caused.
First-party means filing under your own collision coverage. Standard auto policies define the insurer's obligation as repairing or replacing the damaged property, and courts have generally read that as excluding the stigma loss. The well-documented exception is Georgia, where the state Supreme Court's 2001 decision in State Farm Mutual Automobile Insurance Co. v. Mabry held that insurers must assess diminished value on first-party physical damage claims rather than waiting for the policyholder to ask. Georgia drivers can pursue DV even in a single-car accident or when they were at fault, as long as they carry collision coverage. Georgia's insurance regulator is the Office of Commissioner of Insurance and Safety Fire.
Everywhere else, the practical rule as of August 2026: at fault means no DV recovery. If you rear-ended someone, stop here.
The 17c formula, run on real numbers
"17c" is simply paragraph 17(c) of the Georgia consent order that came out of Mabry. It escaped Georgia and is now the default method adjusters across the country reach for. It works in three steps.
Step 1 — base loss. Take the pre-accident value (usually NADA or a comparable guide) and cap the loss at 10%. A $30,000 car has a base loss of $3,000, and that ceiling never moves no matter how severe the damage was.
Step 2 and 3 — the two multipliers.
| Damage modifier | Value | Mileage at time of loss | Value |
|---|---|---|---|
| Severe structural damage | 1.00 | 0 – 19,999 | 1.00 |
| Major structural damage | 0.75 | 20,000 – 39,999 | 0.90 |
| Moderate structural damage | 0.50 | 40,000 – 59,999 | 0.80 |
| Minor damage / panel replacement | 0.25 | 60,000 – 79,999 | 0.70 |
| No structural damage | 0.00 | 80,000 – 99,999 | 0.60 |
| 100,000 and up | 0.00 |
Worked example. A 2024 crossover, pre-accident value $30,000, 45,000 miles, hit hard enough to require frame work classified as major structural damage:
- Base loss: $30,000 × 10% = $3,000
- Damage modifier: $3,000 × 0.75 = $2,250
- Mileage modifier: $2,250 × 0.80 = $1,800
The adjuster's offer is $1,800 on a car that a dealer will now appraise thousands lower. That is not an error — it is what the formula produces. The formula's job was to give insurers a repeatable method, not to measure your actual market loss.
Where 17c pays you exactly zero
Two cells in that table are multiplication by zero, and both catch people off guard.
The odometer cliff. At 99,999 miles the mileage modifier is 0.60. At 100,000 miles it is 0.00. Same car, same crash, same day — the entire claim evaporates over one mile. If you are near that line and your car was struck, note the mileage on the police report and the tow receipt, because the reading at the time of loss is what counts, not the reading when the adjuster looks at it three weeks later.
No structural damage. A bumper cover and a quarter panel replaced with no frame or unibody involvement scores 0.00 on the damage modifier. Insurers will still often pay something on a nearly new luxury vehicle, but the formula itself says zero.
Total losses and leases. If the car was totaled, there is no DV claim — you were paid actual cash value, which already reflects the market. If the car is leased, the diminished value belongs to the titleholder, which is the leasing company, not you. Some lessors will pursue it and some will charge you excess-wear at turn-in for the same accident; read the lease's damage clause before you spend money on an appraisal.
The liability-limit squeeze nobody warns you about
Your repair bill and your diminished value come out of the same property damage liability limit on the other driver's policy. State minimums are low: Florida requires only $10,000 in property damage liability, and Texas requires $25,000 as of 2026.
Run it: your car takes $9,200 in repairs from a driver carrying Florida's $10,000 minimum. Your 17c number is $1,800. The insurer pays the $9,200 repair and has $800 left. You get $800, and the remaining $1,000 is only collectible by suing the driver personally — a person who bought minimum limits and often has nothing to collect.
This is the single biggest reason valid DV claims go unpaid, and it is invisible until you ask the adjuster one question: what is the remaining property damage limit after repairs? Ask it before you pay for an appraisal. If the answer is $800, a $300 appraisal is a losing trade.
How to file and how to beat the formula
- Confirm fault and coverage. Get the claim number from the at-fault carrier and confirm liability is accepted. In Georgia, also open a first-party DV claim with your own insurer.
- Ask for the remaining PD limit after repair costs, per the section above.
- Get an independent appraisal if the numbers justify it. A written DV appraisal commonly runs $200–$400. Appraisers use a market approach — pulling actual asking prices for comparable cars with and without accident history — instead of the 10% cap, and on newer vehicles that routinely lands well above the 17c figure.
- Send a written demand with the repair invoice, the final repair estimate showing structural operations, the vehicle history report showing the accident, and the appraisal.
- Escalate to your state insurance department if the carrier stops responding. The NAIC directory lists every state regulator's complaint portal.
On timing: the deadline to sue the at-fault driver for vehicle damage is a state statute of limitations — 2 years in Texas, 3 years in California and New York, 4 years in Georgia. Those are outer walls, not filing windows. Adjusters close property damage files quickly, and reopening one six months later is far harder than raising DV while the repair claim is still open.
FAQ
Does filing a diminished value claim raise my rates?
A third-party claim is filed against the other driver's policy, so your carrier is not paying and your loss history is not affected. In Georgia, a first-party DV claim rides on a collision claim you have already reported — the claim itself is what shows on your record, not the DV component.
Can I claim diminished value if I already sold the car?
Yes, and a sale can strengthen it. Trade-in or sale paperwork showing the price you got, compared against a clean-history valuation of the same year, model, trim, and mileage, is direct market evidence rather than a formula estimate. Keep the repair invoice and the bill of sale together.
What if the other driver is uninsured?
Uninsured motorist property damage (UMPD) coverage, where your state offers it, pays for vehicle damage but is written as first-party coverage — so outside Georgia it generally carries the same DV exclusion as collision. The realistic remedy is a small-claims action against the driver.
Whether this claim is worth your time
If you were not at fault, the car is under about 60,000 miles, and the repair involved structural work: file it and pay for the independent appraisal. The 17c multipliers are still 0.70 or better here, so the formula gives you a real floor, and the market approach typically beats it — that is the one scenario where a $200–$400 appraisal reliably returns more than it costs.
If the odometer read 100,000 or more at the time of loss: skip the appraisal and demand directly. The mileage modifier is 0.00, so there is no 17c number to negotiate up from; your only path is market evidence, and on a six-figure-mileage car the measurable accident stigma is usually too small to justify the appraisal fee.
If the at-fault driver carries state-minimum property damage and repairs ate most of it: stop. In the Florida $10,000-limit example, an $800 remainder is not worth a $300 appraisal, and suing a minimum-limits driver personally is usually collecting from someone with nothing.
If you were at fault and you are not in Georgia: there is no claim. Standard collision coverage obligates the insurer to repair the car, not to make up the stigma loss — Mabry is what changes that answer, and it changes it in one state.
