Accident Depreciation Calculator
When a vehicle is involved in an accident, its market value often drops—even after repairs. This reduction in value is known as accident depreciation or diminished value. Insurance companies, buyers, and sellers all factor this into pricing.
To make this process simple, the Accident Depreciation Calculator helps you estimate how much value your car has lost due to an accident. Instead of guessing or relying only on insurer estimates, this tool gives you a transparent breakdown of depreciation based on accident severity, original vehicle value, mileage, and market trends.
Whether you are filing an insurance claim, negotiating with a buyer, or just curious about your car’s true worth, this calculator is designed to save you time and provide clarity.
How to Use the Accident Depreciation Calculator
Using the calculator is simple and requires only a few details about your vehicle:
- Enter Original Vehicle Value
- Input your car’s pre-accident market value.
- This can be found using vehicle valuation guides, dealership quotes, or online car pricing tools.
- Select Accident Severity
- Choose the damage level (minor, moderate, or severe).
- Minor dents may reduce value slightly, while major structural damage causes higher depreciation.
- Provide Current Mileage
- Cars with higher mileage generally lose more value post-accident compared to low-mileage vehicles.
- Choose Vehicle Age
- Enter how old the vehicle is in years. Newer vehicles typically suffer higher percentage depreciation after an accident.
- Click “Calculate”
- The calculator will instantly generate an estimated accident depreciation value and the adjusted vehicle value.

Example Calculation
Let’s walk through an example.
- Original Vehicle Value: $25,000
- Accident Severity: Moderate
- Mileage: 45,000 miles
- Vehicle Age: 3 years
👉 After clicking Calculate, the tool estimates:
- Accident Depreciation: $4,000
- Adjusted Value: $21,000
This means that even though the car has been repaired, its resale value is about $21,000, not $25,000, because potential buyers consider the accident history.
