California Diminished Value Claim Calculator
Accidents can reduce the value of your car, even after repairs. In California, vehicle owners have the right to claim diminished value from insurers. Our California Diminished Value Claim Calculator helps you estimate your potential claim and your car’s post-accident value quickly and accurately.
This tool is especially useful for car owners, insurance claims, and legal purposes in California.
What is a Diminished Value Claim in California?
A diminished value claim is a legal claim you can make to an insurance company to recover the loss of market value after your car is repaired from an accident.
Key factors that influence diminished value:
- Vehicle age – older cars lose less value.
- Mileage – higher mileage reduces diminished value slightly.
- Damage severity – minor to severe accidents affect the value differently.
- Repair costs – the claim usually cannot exceed the repair expenses.
California follows the 17c method, which is widely used to calculate diminished value.
How to Use the California Diminished Value Claim Calculator
Step 1: Enter Vehicle Value
Provide your car’s pre-accident market value.
Step 2: Enter Repair Amount
Input the total repair cost from the accident.
Step 3: Select Damage Level
Choose the damage severity:
- Minor (10%) – Scratches, small dents, no structural damage
- Moderate (25%) – Non-structural damage, replaced panels
- Severe (50%) – Structural damage, frame repair
- Major (75%) – Major structural damage, airbag deployment
Step 4: Enter Vehicle Age
Older cars generally have a lower diminished value.
Step 5: Enter Current Mileage
Higher mileage slightly decreases the diminished value.
Step 6: Click Calculate
You’ll see:
- Base Diminished Value – initial estimate before adjustments
- Adjusted for Age/Mileage – California-specific calculation
- Maximum Claim – the amount you can claim (cannot exceed repair cost)
- Post-Accident Value – your vehicle’s current market value after the accident

Example Calculation
Suppose:
- Vehicle Value: $25,000
- Repair Amount: $5,000
- Damage Level: Moderate (25%)
- Vehicle Age: 3 years
- Mileage: 30,000 miles
Step 1: Base Diminished Value = $25,000 × 0.25 × 0.33 = $2,062.50
Step 2: Apply Age Factor = $2,062.50 × (1 − 0.02×3) = $2,062.50 × 0.94 = $1,938.75
Step 3: Mileage Factor (30,000 < 50,000) → factor = 1 → Adjusted Value = $1,938.75
Step 4: Maximum Claim = Min(Adjusted Value, Repair Cost) → Min($1,938.75, $5,000) = $1,938.75
Step 5: Post-Accident Value = Vehicle Value − Max Claim = $25,000 − $1,938.75 = $23,061.25
This means your car lost $1,938.75 in value, and that is the maximum claimable amount under California law.
