After a vehicle accident, your car may lose value even after repairs. This loss, known as diminished value, affects resale price and insurance claims. The Vehicle Diminished Value Calculator helps you quickly estimate your car’s financial loss and post-accident value.

What is Diminished Value?

Diminished value is the difference between your car’s market value before the accident and its value after repairs. Even if your car is fully repaired, buyers and insurance companies recognize it as having been damaged, reducing its market worth.

Factors affecting diminished value include:

  • Vehicle age and mileage
  • Severity of the damage
  • Repair quality
  • Original pre-accident value

How to Use the Vehicle Diminished Value Calculator

  1. Pre-Accident Vehicle Value:
    Enter the market value of your car before the accident.
  2. Current Mileage:
    Input the current odometer reading.
  3. Damage Severity:
    Select the type of damage: Minor (cosmetic), Moderate (panel replacement), Major (structural), or Severe (frame damage).
  4. Repair Quality:
    Choose the repair quality: Excellent (OEM parts), Good (high-quality aftermarket), Average, or Poor (substandard).
  5. Vehicle Age:
    Enter the age of your car in years.
  6. Total Repair Cost:
    Enter the amount spent on repairs.
  7. Click Calculate:
    The calculator will display:
    • Base Diminished Value – initial estimate of loss
    • Adjusted Diminished Value – modified based on age, mileage, and repair quality
    • Value Loss Percentage – percentage of pre-accident value lost
    • Post-Accident Value – estimated market value after repairs
  8. Reset:
    Clear all fields to perform another calculation.

Example

Suppose you have the following data:

  • Pre-Accident Value: $25,000
  • Mileage: 45,000 miles
  • Damage Severity: Moderate
  • Repair Quality: Good
  • Vehicle Age: 5 years
  • Repair Cost: $4,000

Results:

  • Base Diminished Value: $2,500
  • Adjusted Diminished Value: $2,100
  • Value Loss Percentage: 8.4%
  • Post-Accident Value: $22,900

This shows how even moderate damage can significantly affect your vehicle’s market value.
