Free Diminished Value Calculator

Diminished value is the difference between your vehicle's market value before an accident and its market value after repairs. Even with perfect repairs, a vehicle with an accident history is worth less than an identical vehicle without damage history.

Our calculator uses the industry-standard 17c formula, which applies a base 10% diminished value cap, then adjusts based on vehicle condition, damage severity, and repair cost ratio. The formula is widely accepted by insurance companies and courts.

This free estimate provides a preliminary calculation for informational purposes. For insurance claims, you'll need a certified diminished value appraisal from a licensed professional. SnapClaim provides certified reports accepted by all major insurance carriers.

You can claim diminished value when your vehicle was damaged in an accident where another party was at fault. Most states allow diminished value claims against the at-fault driver's insurance, though some states have specific requirements and limitations.

Our calculator provides a reliable estimate based on industry-standard formulas and the information you provide. However, actual diminished value can vary based on specific vehicle details, local market conditions, and accident circumstances. A certified appraisal provides the most accurate assessment.

While our free calculator gives you a solid estimate, insurance companies require a certified diminished value appraisal for claim processing. SnapClaim offers professional appraisals with 1-hour delivery that are accepted by all major insurance companies.
