Frequently Asked Questions
Diminished value is the reduction in a vehicle's resale value after it has been damaged and repaired, even if the repairs are perfect.
Our calculator uses a formula: Pre-Accident Value × Damage Severity Multiplier × Mileage Multiplier × Repair Quality Multiplier. The base loss is 10% of the pre-accident value.
This calculator provides an estimate. Actual diminished value claims may require professional appraisal and vary by jurisdiction.
