What this calculator estimates
Estimate a vehicle diminished-value claim using pre-loss value and adjustable condition factors. It runs locally in the browser and is intended for planning and comparison.
How to use it
Enter the requested values, select Calculate, review the headline result and supporting figures, then change one input at a time to compare scenarios.
How the calculation works
The base loss is a percentage of pre-loss market value and is adjusted for mileage, history and repair quality.
Input checklist
The Auto Accident Diminished Value Claim Calculator uses the values shown in its form. Before calculating, check each input independently so an incorrect unit or time period does not carry through to the final result.
- Vehicle pre-accident market value ($): verify that this value uses the unit, period, and definition shown by the calculator.
- Base damage severity (%): verify that this value uses the unit, period, and definition shown by the calculator.
- Mileage adjustment factor (%): verify that this value uses the unit, period, and definition shown by the calculator.
- Prior-history and condition factor (%): verify that this value uses the unit, period, and definition shown by the calculator.
- Repair quality factor (%): verify that this value uses the unit, period, and definition shown by the calculator.
Practical interpretation
Use the Auto Accident Diminished Value Claim Calculator result as the answer to the specific inputs entered, not as a universal value. The calculation currently described on this page is: The base loss is a percentage of pre-loss market value and is adjusted for mileage, history and repair quality. Change one important input at a time when comparing scenarios so you can see which assumption actually drives the difference.
Checks before relying on the result
Legal outcomes vary by jurisdiction, evidence, damages, policy limits, liability findings, fees, and case-specific facts. The estimate is not a prediction of an award or settlement. Recalculate when a key value changes, and keep the original inputs with the result if you need to reproduce or compare the calculation later.
Important limitations
Insurer formulas and state claim rules differ; an appraisal or comparable-sales analysis may be required.
