Diminished Value Claims: A Comprehensive Overview

If you’ve been in a car accident where the other driver was at fault, you might be entitled to more than just the cost of repairs. Even after your vehicle is fixed, its value can diminish significantly due to the accident history. This reduction in value, known as diminished value, can be a substantial financial loss for car owners. You might have the opportunity to submit a diminished value claim with the at-fault driver’s insurance company to recover the disparity between your car’s value before the accident and its value post-repairs.

What is a Diminished Value Claim?

A diminished value claim empowers you to retrieve the contrast between your car’s value before the accident and its post-repair appraisal, directly from the at-fault driver’s car insurance company.

Even though your vehicle may have been restored to its original condition, the mere fact that it has been in an accident can significantly reduce its market value.

Types of Diminished Value Claims:

There are three different types of diminished value claims, each addressing a unique way in which the vehicle’s value can be diminished after an accident:

1. Immediate Diminished Value:

  • This particular claim seeks to recover the diminished resale value that occurs immediately following an accident or before a vehicle undergoes repairs.
  • It is predominantly employed in legal proceedings and finds limited application elsewhere.

2. Inherent Diminished Value:

  • After an accident, even after proper repairs, a vehicle will lose some market value due to its accident history.
  • This type of claim seeks to recover the difference between the car’s current value and what it would have sold for had it not been involved in an accident.
  • It addresses the fact that a repaired vehicle is worth less to potential buyers than an identical vehicle without an accident history.

3. Repair-Related Diminished Value:

  • If substandard repairs are made to a vehicle following an accident, and it cannot be returned to its original condition, there may be an opportunity to file a claim for repair-related diminished value.
  • Examples include using low-quality parts instead of OEM parts, or issues with paint quality.
  • These types of repair issues can cause the value of the vehicle to diminish further, and you can file a claim for the additional loss in value.

Who Can File a Diminished Value Claim?

Diminished Value Claims - Green Injury Law Firm

Submitting a claim for diminished value can serve as an effective strategy for recovering losses resulting from an accident, but specific criteria must be met.

  • Fault: The other party must have been at fault for the accident. if you’re at fault for the accident, you’re unable to file a diminished value claim with your own insurance provider.
  • Vehicle Ownership: You typically need to own the vehicle outright. Diminished value claims generally cannot be filed for leased vehicles.
  • Vehicle Age and History: Your vehicle should be relatively new (often less than 10 years old) and not have a history of prior accidents or a rebuilt or salvage title.
  • Uninsured/Underinsured Drivers: If an uninsured or underinsured driver was at fault, you may be able to file a diminished value claim with your own insurer against your uninsured motorist property damage coverage, if you have it.
  • State Laws: The rules for diminished value claims vary by state. Most states require the other driver to be at fault, but some states, like Georgia, allow diminished value claims regardless of fault.

How Is Diminished Value Calculated?

The majority of insurance companies employ a standardized method known as the 17c diminished value formula to assess the worth of a vehicle following an accident. Here’s an overview of its operation:

Determine Your Vehicle’s Value:

Use online calculators from resources like NADA or Kelley Blue Book to estimate your vehicle’s value based on factors like make, model, year, mileage, and damage extent.

Calculate the Base Loss of Value:

  • Multiply the vehicle’s value by 0.10 (10%) to determine the base loss of value.
  • This 10% cap is commonly applied by insurers and is the maximum amount you can typically expect to receive.

Apply the Damage Multiplier:

  • Adjust the value based on the severity of the structural damage using a multiplier ranging from 0.00 to 1.00.
  • More severe damage results in a higher multiplier (e.g., 0.75 for major structural and panel damage).

Apply the Mileage Multiplier:

  • Discount the diminished value based on the vehicle’s mileage using a multiplier ranging from 0.00 to 1.00.
  • Higher mileage vehicles have a lower multiplier (e.g., 0.40 for a vehicle with 68,000 miles).

Calculate the Final Diminished Value:

  • Multiply the base loss of value by the damage and mileage multipliers to get the final diminished value amount.

Example Calculation:

Let’s say your vehicle was worth $10,000 based on online estimates and suffered major structural and panel damage in an accident caused by the other driver. It also had 68,000 miles on it.

  • Vehicle Value: $10,000
  • Base Loss of Value: $10,000 x 0.10 = $1,000
  • Damage Multiplier: $1,000 x 0.75 (major damage) = $750
  • Mileage Multiplier: $750 x 0.40 (68,000 miles) = $300
  • Diminished Value: $300

In this case, the diminished value of your vehicle would be $300 based on the factors listed.

Negotiating Diminished Value Claims:

If you find that the diminished value calculated by the insurance company is lower than expected, or if you believe it has been miscalculated, you may be able to negotiate for a higher payout. Here are some tips for negotiating a diminished value claim:

  • Research: Gather information about your car’s special features, estimated value from sources like NADAguides, and comparable sales of similar vehicles in your area.
  • Third-Party Assessment: Request a third-party assessment of the damage to your vehicle and provide an estimate that outlines the full extent of the damage.
  • Documentation: Provide documentation to support your claim, such as repair records, photographs, and any other relevant evidence.
  • Counter-Offer: Based on your research and documentation, present a well-supported counter-offer to the insurance company, explaining why you believe a higher diminished value is justified.

By understanding diminished value claims, the calculation process, and negotiation strategies, you can potentially recover a significant portion of the financial loss caused by an accident that wasn’t your fault.


Being involved in a car accident can be a frustrating and costly experience, even if you weren’t at fault. While insurance may cover the repairs, the decrease in your vehicle’s value due to its accident history can result in a significant financial loss. Fortunately, by understanding diminished value claims, you can take steps to recover some of that lost value.

While insurance companies often use the 17c formula to calculate diminished value, their initial offer may not fully account for your vehicle’s specific circumstances. In such cases, you have the option to negotiate for a higher payout by providing supporting evidence, such as third-party damage assessments, comparable sales data, and information about your vehicle’s special features.

By being proactive and thoroughly documenting your claim, you can increase your chances of receiving fair compensation for the diminished value of your vehicle. Remember, even if you don’t plan on selling your car immediately, taking the time to file a diminished value claim can help protect your investment and ensure that you’re not left footing the bill for an accident that wasn’t your fault.
