Diminished Car Value Calculator
Accidents happen, but do you know how much value your car loses after a collision? Our Diminished Car Value Calculator helps you quickly estimate:
- Diminished Value – the reduction in car value after damage.
- Post-Accident Value – what your car is worth now.
- Value Loss Percentage – percentage of the car’s value lost due to damage.
This tool is perfect for car owners, insurance claims, and buyers who want a realistic idea of a vehicle’s current worth.
What Is Diminished Car Value?
Diminished value refers to the loss of a vehicle’s market value after it has been repaired from an accident. Even after perfect repairs, a car with a history of accidents usually sells for less than a similar vehicle with no damage history.
The diminished value depends on:
- Severity of the accident
- Repair quality and costs
- Mileage of the car
- Pre-accident value of the car
How to Use the Diminished Car Value Calculator
Step 1: Enter Pre-Accident Car Value
Input the market value of your car before the accident.
Step 2: Enter Repair Cost
Enter the total cost required to fix the damage.
Step 3: Select Damage Severity
Choose from:
- Minor (10%)
- Moderate (25%)
- Severe (50%)
- Major (75%)
- Total Loss (100%)
Step 4: Enter Current Mileage
Higher mileage may reduce the diminished value slightly, as older cars lose value faster.
Step 5: Click Calculate
You’ll get:
- Diminished Value – the estimated value lost after the accident.
- Post-Accident Value – your car’s current market value.
- Value Loss Percentage – percentage of value lost due to the accident.
Step 6: Reset if Needed
Click Reset to calculate another vehicle’s diminished value.
Example Calculation
Suppose:
- Pre-Accident Value: $20,000
- Repair Cost: $5,000
- Damage Severity: Moderate (25%)
- Mileage: 35,000 miles
Step 1: Diminished Value = $20,000 × 0.25 × 0.33 = $1,650
Step 2: Adjust for mileage (35,000 > 30,000) → $1,650 × 0.8 = $1,320
Step 3: Post-Accident Value = $20,000 − $1,320 = $18,680
Step 4: Value Loss Percentage = ($1,320 ÷ $20,000) × 100 ≈ 6.6%
This quick calculation shows your car lost $1,320 in value even after repairs.
