Car Diminished Value Calculator

Estimate how much your vehicle’s value has dropped after an accident—even if fully repaired.

What Is Diminished Value and Why It Matters

When a car is involved in an accident—even if it’s repaired to like-new condition—its resale value usually drops. This loss in market value is called diminished value. Insurance may cover repairs, but often won’t automatically compensate for the post-repair value loss unless you file a claim for it.

Types of Diminished Value

  • Immediate Diminished Value: Value loss immediately after the accident, before repairs are made.
  • Inherent Diminished Value: Loss in resale value due to accident history, even after proper repairs (most common).
  • Repair-Related Diminished Value: Loss due to poor repairs, visible defects, or use of non-OEM parts.

How Diminished Value Is Calculated

Most estimates use a formula based on:

  • Pre-accident market value
  • Damage severity
  • Repair cost relative to value
  • Vehicle age, mileage, and prior damage

Sample Formula (Based on Georgia’s 17c Rule)

  1. Start with 10% of the pre-accident value as base diminished value.
  2. Apply a damage severity multiplier:
    • Minor = 0.25
    • Moderate = 0.50
    • Severe = 0.75
  3. Adjust based on mileage and age if necessary.

Typical Diminished Value Estimates

Vehicle Value Damage Severity Estimated DV
$20,000 Minor $500 – $1,000
$30,000 Moderate $1,500 – $2,000
$40,000 Severe $2,500 – $4,000

Does Insurance Pay for Diminished Value?

Only some insurers automatically offer DV compensation—and usually only if the other driver was at fault. You’ll need to file a third-party claim, and in some states like Georgia, it’s easier to collect due to specific case law.

State Recognizes DV? Claim Type
Georgia Yes (17c Rule) Third-party only
California Yes Third-party
Texas Yes Third-party
Michigan No N/A
New York No N/A

Tips for Maximizing Your Diminished Value Claim

  • Get a professional DV appraisal
  • Request a CARFAX history to confirm the damage is reported
  • Gather photos and repair bills
  • File your claim quickly
  • Work with an attorney if your insurer resists paying

Frequently Asked Questions

  • Can leased vehicles claim diminished value? Typically not—the leasing company owns the asset.
  • How long do I have to file a claim? This varies by state—generally 2–4 years from the date of the accident.
  • Is diminished value taxable income? No. It is not considered taxable compensation.
  • What if I was at fault? You likely can’t claim DV unless your own policy allows first-party coverage.
