After an accident, even a fully repaired vehicle can lose value. This reduction in value is known as diminished value (DV). In Texas, understanding how to calculate diminished value is essential for negotiating insurance claims, especially in third-party cases.

The Texas Diminished Value Calculator simplifies this process, giving you an accurate estimate based on vehicle value, age, mileage, damage severity, repair cost, and condition.

What is Diminished Value?

Diminished value is the difference between a vehicle's pre-accident market value and its post-repair value. Even after high-quality repairs, buyers and insurers may consider a previously damaged vehicle less valuable.

  • Example: A car worth $20,000 before an accident may be worth $18,000 afterward, even if fully repaired. The diminished value is $2,000.

Texas law allows owners to claim diminished value from the at-fault party's insurance, but first-party insurance claims often don’t cover this.

Key Factors Affecting Diminished Value

  1. Vehicle Age and Mileage:
    Older vehicles or those with high mileage lose less value after an accident.
  2. Damage Severity:
    • Cosmetic scratches reduce value slightly
    • Structural or frame damage reduces it significantly
  3. Vehicle Condition Pre-Accident:
    • Excellent or like-new vehicles experience higher diminished value
    • Fair-condition cars experience lower DV
  4. Repair Quality:
    High-quality repairs may slightly reduce DV, but cannot fully restore market perception.
  5. Claim Type:
    • Third-party claims in Texas are eligible for DV compensation
    • First-party claims usually are not covered for DV
