Diminished Value Calculator (17c + Market Method)
Even after a quality repair, a vehicle with an accident on its history sells for less. That loss is diminished value. This tool shows both the insurer's 17c formula and a transparent market-based range side by side — as a range, never a single false number — and flags whether a claim is even available in your situation.
Estimate your diminished value range
Enter your pre-accident value, damage severity, and mileage. The 17c and market estimates update live and bracket your likely loss.
Estimated diminished value range
$672 – $1,680
A range, not a single figure — the two methods below bracket what your loss likely falls between.
Insurer 17c estimate
$840
The formula insurers favor — treat it as a floor, not a ceiling. It caps at 10% of value and zeroes out at 100k+ miles.
Market-based range
$672 – $1,680
What comparable buyers actually discount for a prior accident — often higher than 17c. Best supported by a professional appraisal.

Third-party DV is recognized in most states
Diminished value claimed against the AT-FAULT driver's insurer is recognized in most states, though a few limit or bar it. Availability and proof requirements still vary by state.
Educational estimate only. Diminished value depends on make/model demand, repair quality, and local market, and is best documented with an independent appraisal. Calculations run in your browser; nothing is saved.

The insurer's formula is designed to be conservative — your real loss is often higher.
The 17c formula caps the loss at 10% of your car's value and then discounts heavily for mileage and lesser damage. It's convenient for insurers, but it routinely understates what the market actually does to a previously-wrecked car. That's why this tool shows it next to a market-based range rather than on its own.
The honest answer to “how much value did I lose?” is a range. Use the 17c number to understand the insurer's opening position, and the market range — ideally backed by an independent appraisal — to argue for fair value.
First-party vs third-party — does a claim even exist?
This is the threshold question, and it's easy to miss.
A third-party diminished-value claim — against the at-fault driver's insurer — is recognized in most states. A first-party claim against your own insurer is a different story: most states do not allow it (Georgia is the well-known exception). Before investing in an appraisal, confirm which situation you're in and whether your state permits the claim at all.
Documenting and demanding your diminished value
A number is only as good as the proof behind it.
The strongest diminished-value claims pair an independent appraisal with repair records and the vehicle-history report showing the accident. JusticeFinder is preparing a dedicated Diminished Value Claim Kit ($27) — an appraisal checklist and demand-letter template — to package that proof; it isn't available for purchase yet, so this tool simply points you to free documentation resources in the meantime.

Frequently Asked Questions
What is diminished value?
It's the difference between what your vehicle was worth before the accident and what it's worth after, even once repairs are done — because buyers pay less for a car with a crash on its record.
What is the 17c formula?
It's a calculation many insurers use: a 10% cap on the pre-accident value, adjusted down for damage severity and mileage. It's widely criticized as a low-ball, so treat it as a floor rather than a fair number.
Why show a range instead of one number?
Because diminished value genuinely varies with the make, model, market, and repair quality. The 17c figure and a market-based band bracket the realistic loss; a single 'your DV is $X' number would be misleading.
Can I claim diminished value against my own insurer?
Usually not. First-party diminished value claims are barred in most states (Georgia is the notable exception). Third-party claims — against the at-fault driver's insurer — are recognized in most states, though rules vary.
How do I prove diminished value?
The strongest support is an independent diminished-value appraisal documenting comparable sales, plus your repair records and the vehicle history report showing the accident.
Educational Use Disclaimer
This calculator is an educational estimate only and does not constitute legal or appraisal advice. Diminished value, the 17c formula's appropriateness, and whether a first-party or third-party claim is allowed all vary by state, insurer, and vehicle. A professional appraisal and a licensed attorney are the right sources before you rely on any figure.
