Texas Diminished Value Calculator (17c Formula Estimate)

This calculator provides an estimated diminished value for your vehicle in Texas, based on a simplified adaptation of the "17c Formula." Diminished value is the loss in a vehicle's resale value after it has been damaged and repaired, even if the repairs are perfect. This formula is a common starting point used by insurance adjusters, though it is not legally binding and actual diminished value can vary.

(e.g., NADA, Kelley Blue Book value before the accident)
Minor Panel/Paint, No Structural Damage Minor Structural Damage, Major Panel/Paint Moderate Structural Damage, Major Panel/Paint Severe Structural Damage, Frame Damage (Multiplier applied to base loss)
Under 20,000 miles 20,000 – 50,000 miles 50,000 – 100,000 miles Over 100,000 miles (Multiplier applied based on mileage)

Understanding Diminished Value in Texas

When your vehicle is involved in an accident, even if it's perfectly repaired, its market value often decreases. This reduction in value is known as "diminished value." Buyers are generally less willing to pay as much for a vehicle with an accident history, regardless of the quality of repairs. In Texas, you have the right to pursue a diminished value claim against the at-fault driver's insurance company.

The concept of diminished value is recognized in Texas law, allowing vehicle owners to recover not just the cost of repairs, but also the loss in market value. This is particularly relevant for newer vehicles, luxury cars, or those with low mileage, where an accident history can significantly impact resale potential.

The 17c Formula: A Common Starting Point

While there's no single legally mandated formula for calculating diminished value in Texas, the "17c Formula" is frequently used by insurance adjusters as a baseline. It's important to understand that this formula is a simplified model and often serves as a starting point for negotiations, not a definitive final value.

The basic steps of the 17c Formula typically involve:

  1. Base Loss: Starting with 10% of the vehicle's pre-accident market value (e.g., NADA or Kelley Blue Book).
  2. Damage Multiplier: Adjusting the base loss based on the severity of the damage (e.g., structural damage, panel replacement, paint only). More severe damage leads to a higher multiplier.
  3. Mileage Multiplier: Further adjusting the value based on the vehicle's mileage. Lower mileage vehicles generally experience a greater percentage of diminished value.

Our calculator uses these principles to provide an estimate. However, many other factors can influence the actual diminished value, such as the specific make and model, desirability, repair quality, and local market conditions.

Important Considerations

  • Not Legally Binding: The 17c Formula is a tool, not a legal requirement. Insurance companies may use it, but you are not bound by it.
  • Professional Appraisal: For an accurate assessment, especially for high-value vehicles or significant damage, it is highly recommended to obtain an independent diminished value appraisal from a qualified expert.
  • Negotiation: The initial offer from an insurance company for diminished value may be low. Be prepared to negotiate and provide evidence to support your claim.
  • Documentation: Keep thorough records of the accident, repair estimates, repair invoices, and any pre-accident vehicle appraisals or market value reports.

This calculator is designed to give you a preliminary estimate to help you understand the potential diminished value of your vehicle in Texas. For a precise claim, always consult with a professional appraiser or legal counsel.
