What is vehicle depreciation?

Vehicle depreciation is the drop in value that a vehicle repaired after an accident suffers on the second-hand market compared with undamaged equivalents. The vehicle's damage record creates distrust in the eyes of buyers, so the vehicle sells below its market value. This difference can be claimed from the insurer of the party at fault.

Information required for the calculation

For a sound calculation, the following information must be entered in full:

  • The vehicle's make, model and model year
  • Accident date and damaged areas
  • Mileage at the time of the accident
  • Pre-repair and post-repair appraisal reports
  • The vehicle's previous damage history, if any
  • Post-accident repair invoices

Tip

The appraisal report and repair invoices increase the accuracy of the calculation. Pre-accident photographs of the vehicle and market value research are also useful.

  1. Enter the vehicle information: Make, model, model year, mileage.
  2. Add the damage history: Accident date, damage condition, repaired parts.
  3. Market value determination: The system automatically determines the vehicle's market value with current market data.
