Why did my car insurance go up when I had no claims?

Your premium can increase even without claims due to statewide rate changes, higher vehicle repair costs, increased local claim activity, changes in credit-based insurance scores where permitted, lost discounts, address changes, or updates to your vehicle's risk rating.

Can insurance raise rates without telling me?

Insurance companies generally provide renewal notices that show your new premium before the next policy term begins. Notification requirements vary by state, so it is important to review all renewal documents before your payment due date.

Does credit affect car insurance?

In many states, insurers may use credit-based insurance scores as part of underwriting and rating decisions. Some states restrict or prohibit the use of credit information. According to the National Association of Insurance Commissioners (NAIC), most auto and homeowners insurers use credit-related data where permitted by law.

Will my rate go down if I stay with the same company?

Possibly, but staying with the same insurer does not guarantee lower premiums. Your rate can change because of company-wide pricing adjustments, claims trends, available discounts, driver information, vehicle factors, and coverage selections.

Is it better to lower coverage to save money?

Reducing coverage can lower your premium, but it may also increase your financial risk after an accident. Before reducing liability limits or vehicle protection coverage, consider reviewing deductible options, available discounts, and alternative ways to reduce costs.

How often should I compare car insurance quotes?

It is generally recommended to compare auto insurance quotes at least once a year. You should also shop for new quotes after major life changes such as moving, adding a driver, purchasing a vehicle, or receiving a significant premium increase at renewal.

Can I Claim Diminished Value After a Car Accident?

Reviewed by the AtozInsuranceusa editorial team.

Yes, you may claim diminished value if an accident leaves your car worth less after repairs and state law allows payment for that loss. A common route is a claim against the responsible driver’s insurer. Claims under your own policy depend on its terms and applicable state law.

Diminished value means the loss in market value that remains after repairs. It differs from the money needed to fix the car.

For example, assume your car had a fair market value of $25,000 before a crash. After proper repairs, credible market evidence supports a value of $22,500 because of the accident history. The potential diminished value is $2,500.

That example does not guarantee a payment. You still need to establish liability, available coverage, and the value loss.

Start by checking:

Who caused the crash?
Which insurer should review the claim?
Whether repairs have restored the car’s condition.
What evidence supports a lower market value.
Whether you signed a release.
Which notice and legal deadlines apply.

Texas insurance guidance recognizes that an insurer may owe a third party for lost market value even after complete repairs. It treats claims under the owner’s own policy differently.

Raise the issue before accepting a final property damage settlement. A repair payment and a diminished value payment address different parts of the loss.

What Does Diminished Value Mean?

A repaired vehicle can function properly yet attract a lower price because buyers know about its crash history.

Your claim concerns the accident’s effect on value. It does not cover normal aging, added mileage, or a broad drop in used car prices.

Compare values on a consistent basis. Do not compare yesterday’s retail value with today’s dealer trade offer and treat the whole gap as accident damage.

Value issue	What it measures
Repair cost	The cost to restore covered physical damage
Diminished value after repairs	Market value loss that remains because of the accident
Ordinary depreciation	Value changes from age, mileage, wear, and market conditions
Total loss valuation	The vehicle’s value for a claim that treats it as a total loss

A low offer alone does not explain why the price fell. Ask the buyer or appraiser to identify the accident related adjustment.

What Types of Diminished Value Might Come Up?

Loss From Accident History

People often call this inherent diminished value. The car may have sound repairs, but its history still affects what buyers will pay.

Loss From Incomplete or Poor Repairs

Unresolved damage can create a separate repair dispute. Ask the shop and adjuster to inspect problems such as poor panel fit, warning lights, or unfinished work.

Do not accept unsafe repairs in exchange for a resale value payment.

Loss Before Repairs

A damaged, unrepaired car usually presents a different valuation question from a properly repaired one.

Avoid adding the full repair cost to the unrepaired value gap without checking the legal measure of loss. That approach can count the same damage twice.

Tell the insurer which loss you seek and whether repairs remain incomplete.

Which Insurance Company Should I Contact?

The Responsible Driver’s Insurer

A claim against someone else’s liability coverage is a third party claim.

Ask that insurer to confirm whether it accepts liability and whether it will review diminished value separately from repairs.

Its payment can depend on state law, fault, proof of loss, and policy limits.

Your Own Insurer

A claim under your own policy is a first party claim. Repair coverage does not automatically establish diminished value coverage.

Georgia offers a significant example. In State Farm v. Mabry, the Georgia Supreme Court held that the policy language at issue required payment for diminished value when it occurred, and upheld a duty to evaluate it.

Do not apply that ruling to all policies nationwide.

An Uninsured Motorist Claim

Ask whether applicable uninsured or underinsured motorist property damage coverage includes the loss.

Texas’s bulletin notes that such coverage may create an obligation to pay lost market value. Coverage and rules elsewhere can differ.

A collision claim and an uninsured motorist claim can involve different terms.

Who Has a Stronger Diminished Value Claim?

Focus on evidence rather than a promise that certain cars always qualify.

Ask an appraiser to evaluate:

The car’s age, mileage, trim, and condition.
Its value before this crash.
Prior accident and repair history.
The location and extent of the new damage.
Repair quality.
Demand for similar vehicles.
Market evidence of an accident related price reduction.

A newer car with documented structural repairs may justify a closer review. An older car with prior damage may require more work to isolate the additional loss.

Neither example creates an automatic approval or denial.

Washington’s insurance regulator advises people seeking diminished value to prove the claim with supporting documents.

The useful question is: “What evidence shows this accident caused a remaining loss in this car’s value?”

How Do I Calculate Diminished Value?

Start with this concept:

Potential diminished value = supported value before the crash minus supported value after repairs.

The challenge lies in supporting both figures.

Use comparable vehicles with similar model years, trim, mileage, options, and condition. Account for prior damage.

An asking price does not prove a completed sale price. A dealer offer may also reflect its desired margin or inventory needs.

Ask the appraiser to explain those differences.

A Hypothetical Valuation Example

Valuation detail	Example
Supported value before the crash	$30,000
Supported value after completed repairs	$27,000
Claimed remaining value loss	$3,000
Separate approved repair cost	$8,000

The $3,000 request does not arise merely because repairs cost $8,000. It needs its own market support.

Avoid assuming all repaired cars lose the same percentage. Ask why each adjustment fits your vehicle.

What Is the 17c Formula?

You may encounter a calculation called the 17c formula.

A research article in the Journal of Insurance Regulation describes it as 10% of a retail value figure, multiplied by damage and mileage modifiers. The article also discusses criticisms, including possible double counting of mileage.

Here is a hypothetical calculation:

Input	Example
Vehicle retail value	$30,000
Starting factor	10%
Assumed damage modifier	0.50
Assumed mileage modifier	0.80
Calculated result	$1,200

The math is $30,000 × 0.10 × 0.50 × 0.80.

That result is not a guaranteed settlement or a nationwide legal limit.

If an insurer uses a formula, request its inputs and explanation. Ask why its damage and mileage adjustments fit your car.

A calculation can organize an estimate. It does not replace proof that the result reflects the market loss.

What Evidence Should I Gather?

Build one claim folder with:

The accident date and claim numbers.
Vehicle identification number and ownership details.
Photos from before and after repairs.
Repair estimates, supplements, and final invoices.
Inspection, alignment, scan, or calibration records when relevant.
Prior service and accident records.
A vehicle history report.
Comparable vehicle data.
Written dealer observations or valuation reports.
Any independent appraisal.

Keep originals and submit clear copies.

A vehicle history report can document an accident entry. It does not establish the dollar loss by itself.

Ask any dealer who reduces an offer to explain the reduction in writing. Separate ordinary trade pricing from the effect of crash history.

For help with the conversation, read what to say to an insurance adjuster after a crash.

How Do I File a Diminished Value Claim?

Step 1: Notify the Adjuster

Say that you want a review of any remaining market value loss. Ask whether the insurer has a form, document list, or specific submission channel.

Step 2: Check Liability and Coverage

Ask whether any dispute concerns fault, coverage, valuation, or all three. Those issues need different responses.

Step 3: Document Completed Repairs

Obtain the final repair invoice and address unresolved defects. You can raise the issue early while explaining that final valuation evidence will follow.

Step 4: Submit a Clear Request

Include your requested amount, its calculation, and the evidence behind it.

Step 5: Request a Written Response

Ask the insurer to explain its decision and any competing valuation.

Step 6: Track the File

Save submission confirmations, correspondence, and follow up dates.

Keep repair payments, rental expenses, deductible repayment, and diminished value in separate entries. That makes it easier to avoid duplicate requests.

Should I Hire an Independent Appraiser?

Consider an appraisal when the potential loss and evidence justify the fee.

Before hiring anyone, ask:

What credentials or state license do you hold?
Will you inspect the vehicle?
How will you select comparable vehicles?
Will the report address prior damage?
What does the fee include?
Will you explain the report if the insurer questions it?

Avoid paying for a promised settlement amount.

A report should explain its reasoning, assumptions, and limits. A large number without support may not help.

Hypothetical cost check: A $400 report may deserve consideration for a well supported dispute involving several thousand dollars. The same fee may make less sense when credible evidence suggests only a small loss.

Neither situation guarantees that the insurer will reimburse the appraisal fee.

What if the Insurer Denies the Claim or Offers Too Little?

Ask for the reason in writing.

Then match your response to the issue:

Insurer’s position	Useful next step
The policy excludes the loss	Request the relevant policy wording and state basis
The car had prior damage	Show the condition and history before this crash
Repairs restored the full value	Submit evidence of a remaining market reduction
The requested amount lacks support	Improve the appraisal or comparable data
Liability remains disputed	Provide accident evidence and seek appropriate advice
A release settled the loss	Have a lawyer review the signed agreement

You may request a supervisor’s review. A state insurance department may help with claim handling concerns, but it does not guarantee your requested valuation.

Can Appraisal Resolve a Value Dispute?

Check the policy and state law. Do not assume an appraisal clause applies to every diminished value dispute.

North Carolina has a statutory process for certain vehicle value disputes when liability for coverage is not disputed.

Its threshold concerns a disagreement greater than $2,000 or 25% of the vehicle’s specified value before the accident, whichever is less. Additional conditions and procedures apply.

That is a threshold for the difference between the two estimates. It is not a minimum diminished value payment.

Ask a qualified professional whether the process applies before paying fees or making a formal demand.

Appraisal generally addresses a valuation question under its governing rules. Do not assume an appraiser can decide every coverage or liability issue.

How Long Do I Have to File?

No single national deadline applies.

Several clocks can matter:

Policy notice requirements.
Deadlines for requested documents.
State claim handling rules.
The legal deadline for a lawsuit.
Terms in an agreement you already signed.

Ask about the applicable deadlines early. Do not assume repair completion restarts the legal clock.

Tell the adjuster in writing that you seek review of diminished value, even if you still await final documents.

Seek local legal advice if a deadline approaches. Negotiations or an insurance department complaint may not stop the time allowed to sue.

Keep a dated record of each notice and submission.

Can a Settlement Release End My Claim?

A release may settle more than the repair bill. Read its scope before signing.

Ask whether it covers all property damage, diminished value, rental costs, or other losses.

Do not assume writing “diminished value pending” in a separate email overrides a broad signed release.

If you want to settle repairs while preserving another claim, ask a lawyer to review the arrangement.

Also coordinate with your insurer if it has paid part of the loss. California’s insurance department warns that releasing the responsible party can harm your insurer’s repayment rights.

For related questions, see whether a closed car insurance claim can reopen.

What if the Car Is Financed, Leased, or a Total Loss?

Financed or Leased Cars

Tell the adjuster about the lender or leasing company.

Ask who owns the claim, who must endorse payment, and what the contract requires. A leasing arrangement may create different rights from owning a financed vehicle.

Do not assume any diminished value payment will come directly to you.

Total Loss Claims

A total loss claim usually focuses on the vehicle’s value immediately before the crash. A separate after repair loss generally does not fit when the insurer does not repair the car.

Check the valuation, comparable vehicles, options, mileage, and condition adjustments.

Read how to negotiate an insurance payout for a totaled car if your dispute concerns that settlement.

How Can I Make My Evidence Easier to Review?

Prepare a short cover sheet before sending a large file.

List the accident date, vehicle details, completed repair date, amount requested, and documents that support the amount. Number the attachments so the adjuster can find them.

For example, label the final invoice as Attachment 1, the appraisal as Attachment 2, and comparable vehicle data as Attachment 3.

Explain any gap in your evidence. If you have dealer opinions but no completed sale, say so. If an appraisal relies on photographs rather than an inspection, disclose that limit.

Ask the insurer to identify any missing information in its response. A clear file helps both sides focus on the disputed value.

Frequently Asked Questions

Do I Have to Sell My Car to Claim Diminished Value?

A market value claim can involve an appraised loss without an actual sale, depending on applicable law. Ask which proof the insurer requires. A documented sale may provide evidence, but selling is not a universal condition for seeking review.

Can I Claim Diminished Value if I Caused the Accident?

A claim against your own insurer depends on your policy and state law. Do not assume collision repair coverage includes this benefit. Ask for the policy provision and legal basis. Georgia’s rules differ from those in many other states.

Does a Minor Accident Automatically Qualify?

No automatic payment follows from an accident entry or a repair bill. You need a supported remaining loss under an available legal or coverage route. Damage severity, repair quality, prior history, and market evidence can affect the evaluation.

Can I Claim if My Car Had an Earlier Accident?

Prior damage does not answer the whole question. You need to isolate any additional loss from the new crash. Provide accurate history and evidence of the car’s condition beforehand. Do not value a previously damaged car as if it had a clean history.

Does a Repair Payment Include Diminished Value Automatically?

Ask the adjuster to identify each part of the settlement. Do not assume a repair payment includes or preserves a separate value claim. Request a written breakdown and check any release before accepting a final settlement.

Is Diminished Value Always 10% of the Car’s Value?

No. A formula’s starting factor does not establish the actual loss or a national legal entitlement. Ask for market evidence and the method’s assumptions. Your supported claim could differ from a formula result, subject to applicable rules.

What Should You Do Next?

Check the claim route, document the repairs, and gather evidence of any remaining market loss. Raise the issue before signing a final release, and confirm the deadlines that apply.

AtozInsuranceusa encourages you to compare coverage with your needs and ask clear questions about claim terms. For a diminished value dispute, consult a qualified vehicle appraiser and seek licensed legal advice when coverage, liability, or deadlines remain unclear.
