How to File a Diminished Value Claim

If your car is damaged, whether from an accident or another mishap — such as a tree falling on it in a storm — you may be able to file a claim for diminished value. What is a diminished value claim? Simply put, your car loses value after an accident, even if it is carefully repaired. Potential buyers who have access to the car’s history will know that it was previously damaged and will likely offer you less money for it. The difference between the car’s value before and after the accident is called its diminished value. To help you understand how this may impact you and your vehicle, Bankrate’s insurance editorial team created this guide, explaining the process and giving you all the information you need to file your claim.

What is diminished value?

After an accident, your car’s market value decreases even if it’s restored back to its pre-accident condition following repairs. Diminished value is the difference in your car’s market value before and after an accident. Even if you try to resell your vehicle, CARFAX and other similar reports will show that it has been involved in an accident, which will likely reduce its market value. A diminished value claim — or diminution in value claim — may help recover the loss in value you may take when you go to sell your car or trade it in for a different vehicle if it has been involved in an accident or other covered damage incident.

Types of diminished value

There are three types of diminished value. Each type relates to the depreciation in the cost of your vehicle after an accident.

Inherent diminished value

This is the most common and accepted form of auto accident diminished value. Inherent diminished value occurs when a vehicle loses value because it now has a history of damage, which is indicated in the car’s history reports. This type of diminished value assumes that the vehicle’s repairs were of optimal quality and represents the amount the vehicle’s worth will decrease based on the accident history.

Immediate diminished value

This type of vehicle diminished value represents the difference in resale value immediately after an accident and before the vehicle is repaired. Although this is the type of diminished value that court systems use, it is rarely used when filing a diminished value claim with an insurance company since the company typically covers the cost of repairs after a covered accident, provided you have the necessary coverage types in place.

Repair-related diminished value

This refers to the loss of the vehicle’s value based on low-quality repairs performed after an accident. For example, if the paint is repaired with a color that is not an exact match or if aftermarket parts are used in place of original equipment manufacturers (OEM) parts. In these cases, the quality of the repair leaves a loss in value beyond the diminished value of the vehicle that now exists because of the accident. This diminished value assumes that the vehicle is unable to be restored to its condition prior to the accident.

Calculating diminished value

Most insurance companies use a calculation called the 17c Diminished Value Formula to determine the value of a vehicle post-accident. This formula originated in a Georgia claims case involving a State Farm diminished value claim, where it appeared in paragraph 17, section c (which is where it got its name). Below are the steps used to calculate diminished value under this formula.

Step 1: Determine the value of your car

You can determine the sales, or market, value of your vehicle using the NADA or Kelley Blue Book websites. Both offer a calculator where you can input a few pieces of information regarding your vehicle. You will need to include the year, make, model, mileage and the extent of damage done to your car.

Step 2: Apply a 10% cap to that value

Insurance companies commonly apply a 10 percent cap — known as the base loss of value — to the sales value of your vehicle estimated by NADA or the Kelley Blue Book diminished value calculator. This cap is the maximum amount your insurance company will pay on the claim.

Step 3: Apply a damage multiplier

Insurance companies use a damage multiplier to adjust the value of the vehicle described in step two. The 10 percent cap value is multiplied by a number ranging from 0.00 to 1.00 according to the structural damage done to your car after an accident. The 0.00 multiplier represents no structural damage or replaced panels, while the 1.00 multiplier represents vehicles with severe structural damage.

Step 4: Apply a mileage multiplier

While NADA and Kelley Blue Book take the mileage of your car into consideration when determining the value, insurance companies calculate their own mileage deduction. The adjusted value in step three is multiplied by one of these mileage multipliers to calculate the final diminished value of your vehicle.

To summarize, to calculate the diminished value of your car under formula 17c, you would take your vehicle value and multiply it by a 10 percent cap. You would then apply a damage multiplier based on the damage to your car and a mileage multiplier based on your mileage.

For example, if the market value of your vehicle is $15,000 with moderate damage to structure and panels and 20,000 miles, your formula to calculate diminished value would be:

$15,000 x .10 = $1,500 — This would be the maximum you would receive for a diminished value from an auto insurer.

$1,500 x .50 = $750 — This would be the value adjusted for moderate damage.

$750 x .80 = $600 — This would be the value adjusted for vehicles with 20,000 miles.

Based on this example, an auto insurer would pay out a maximum of $1,500 for a diminished value claim on this vehicle. However, based on the damage and mileage, the final calculated estimate for a diminished value payout would be $600 for this vehicle. This means that the insurance company may pay the owner $600 to compensate for the diminished value of their vehicle caused by the accident damage.

How to file a diminished value claim

Filing a diminished value claim may be more involved than filing a claim for other issues because the burden of proving the car’s diminished value is generally your responsibility.

If you are deemed at fault in the accident, your diminished value claim will likely be denied. If the other driver is at fault, then you would likely contact their auto insurer to discuss how to file a diminished value claim with them.

Here are the steps you may need to take to file a diminished value claim:

1. Check the insurance company’s process for filing a diminished value claim.
2. Document the car’s market value using Kelley Blue Book or NADA calculator tools.
3. Prove your car’s diminished value. Having photos and documents of the accident scene and damage to your vehicle may help your case. You may need to get an appraisal from a certified vehicle appraiser as part of the claims process.
4. Satisfy all the insurance company’s conditions for diminished value and file your claim. This may give you the best chance of having your diminished value claim approved.

It is important to note that state regulations may also affect how diminished value claims are handled. Since every state has different statutes regarding insurance, researching state laws may better help you understand your rights regarding the diminished value of your vehicle.

Considerations when filing a diminished value claim

It does take more time and effort to file a diminished value claim, and there is no guarantee that you will receive compensation after you file. However, not everyone needs to file a diminished value claim. Before beginning the filing process, take the following into account:

• Your vehicle’s value before the accident: If you drive an older car that has a lot of mileage or structural damages, you may not receive a payout for diminished value.
• Whether you were at fault: If you caused the accident, then your insurance company most likely will not pay a diminished value claim.
• If you are involved in an accident with an uninsured driver: If you have uninsured motorist coverage with your insurer, you may have a slightly better chance of receiving compensation from a diminished value claim.
• What state you live in: Every state has different regulations around diminished value claims.

Since each state goes by different statutes for diminished value payouts, it is important to research the regulations in your state. All states except Michigan allow for some level of diminished value claim to be filed if the other party is at fault, according to the Insurance Information Institute.

When to file a diminished claim

If you are involved in an accident where the other party is at fault, it may make sense to file a diminished value claim so you can recover the difference in your vehicle’s value. In most cases, you cannot file a diminished claim against your own insurance company, which means attempting to file it if you are at fault in an accident will most likely be denied. You may be able to file a diminished value claim with your own insurance company if the at-fault driver is an uninsured motorist or you are the victim of a hit-and-run.

It is generally best to file for a diminished claim with the at-fault party’s insurance company as soon as possible, preferably in the days after the accident occurs. It is often easier to present your case (with supporting documentation) when you file quickly. Also, the value of your vehicle could decrease the longer you wait to file a claim. Each state has its own statute of limitations, which require you to file a claim within a certain time frame from the accident.

Frequently asked questions

• Is a diminished value claim worth it?

  It could be, but that depends partly on your car’s mileage and the extent of the damage. A relatively new, low-mileage car with extensive damage due to an accident or other mishap is more likely to lead to a successful diminished claim than an older, high-mileage car that did not suffer extensive damage in the accident. You are also unlikely to file a successful claim if you were found to be at fault in the accident. Filing a claim may take time and energy, but it could be worth it in the end and may help justify the amount you pay for your coverage.

• Do all car insurance companies allow diminished value claims?

  Just about all car insurance companies will allow you to file a diminished value claim, but there is no guarantee that you will be successful. Most companies will not approve a claim, for example, if you are found to be at fault in the accident. You are also more likely to have a successful claim if your car is on the newer side and in good condition. In addition, the fewer miles you have on your car, the more likely your claim will yield a substantial payment. Your state’s insurance laws may also impact your ability to file a successful claim.

• Are insurance companies required to pay a diminished value claim?

  If the other driver is at fault in your accident and has auto insurance, then you should be entitled to a diminished value claim. However, it is primarily up to you to prove your car’s diminished value, and the insurer will likely only pay the claim if you can do so effectively. It is also important to note that state regulations vary, and each state will handle claims differently. Michigan drivers may have more difficulty getting a diminished value claim approved compared to other states.

• How long does it take to get a diminished value claim?

  Settling a diminished value claim typically takes longer than a standard auto claim because they’re often more complex. Some drivers find that it takes weeks or months to finalize a diminished value claim. While hiring a personal lawyer to act on your behalf with the insurance company might help you achieve a favorable outcome, it can also add to the length of the process.

• Who can file a diminished value claim?

  Diminished value claims are allowed by drivers in all states except Michigan as long as the other party is at fault. There may be other state rules and regulations, however, that impact your ability to file a claim. In some states, you need to file your claim within a certain amount of time. In California, for example, the claim must be filed with your insurance company within three years of the accident. It is unlikely that a claim would be successful if you are found to be at fault in the accident. If the damage is minor and your car has extensive miles on it, you may not find it worthwhile to file a claim since it’s unlikely that a claim would amount to a significant payout.
