What Is Diminished Value?
Diminished value refers to the reduction in a vehicle’s market worth after it has been damaged and repaired. Even if the repairs restore your car to its pre-accident condition, buyers and insurers often consider vehicles with an accident history as less valuable.
There are three primary types of diminished value:
- Immediate Diminished Value: The loss in value right after the accident before any repairs.
- Inherent Diminished Value: The reduction in value due to the vehicle’s accident history, even after quality repairs.
- Repair-Related Diminished Value: Loss caused by substandard or visibly noticeable repairs.
This calculator focuses on inherent diminished value, helping you estimate a fair reduction in resale or trade-in value.
How the Diminished Value Calculator Works
The calculator estimates your vehicle’s diminished value using three inputs:
- Vehicle Pre-Accident Value ($): The market value of your car before the accident.
- Damage Severity (%): A percentage estimate of how severe the accident damage was.
- Market Adjustment ($): Optional adjustments reflecting local market conditions or additional depreciation factors.
The formula applied is:DiminishedValue=(VehicleValue×DamagePercent÷100)−MarketAdjustment
This ensures that the calculation is transparent, simple, and reflective of real-world depreciation.
How To Use the Diminished Value Calculator
Step 1: Enter Vehicle Pre-Accident Value
Input the estimated market value of your vehicle before the accident. Use sources like KBB, NADA, or local car listings for accuracy.
Example:
- $25,000 for a 2020 sedan
- $40,000 for an SUV
Step 2: Enter Damage Severity (%)
Estimate the percentage of damage severity based on repair costs and the impact on vehicle performance or appearance.
- Minor damage: 5–15%
- Moderate damage: 15–35%
- Severe damage: 35–70%
Step 3: Enter Market Adjustment ($)
Input any additional deductions reflecting local resale market trends or cosmetic factors that may affect resale value.
Example:
- $500 market adjustment for older vehicles
- $0 if no additional adjustments apply
Step 4: Click “Calculate”
The tool will instantly display your estimated diminished value. The result is formatted for clarity and can be copied or shared with insurers, buyers, or auto repair shops.

Example Calculation
Let’s say:
- Vehicle Value: $30,000
- Damage Severity: 20%
- Market Adjustment: $500
DiminishedValue=(30,000×0.2)−500=6,000−500=5,500
Your vehicle has an estimated diminished value of $5,500 after the accident.
