Kbb Diminished Value Calculator

When a vehicle is involved in an accident, even after repairs, its market value often drops. This is called diminished value (DV)—the difference between your car’s worth before and after an accident.

Insurance companies, buyers, and sellers frequently use diminished value calculators to estimate how much an accident impacts a car’s resale value. The KBB Diminished Value Calculator is designed to give you a quick, reliable estimate using the widely recognized 17c formula—a standard method adopted by insurers.

This tool helps you:

• Understand how much value your car lost after an accident.
• Support insurance claims for compensation.
• Make better decisions when selling or trading your car.
• Have transparent information when negotiating with buyers.

How the KBB Diminished Value Calculator Works

The calculator uses the 17c formula, which considers several factors:

1. Base Loss: 10% of the pre-accident value.
2. Damage Severity Multiplier: Adjusts based on whether the damage was minor, moderate, or major.
3. Age Multiplier: Reduces DV as the car gets older (capped at 80%).
4. Salvage Status: If the car was declared salvaged/rebuilt, the diminished value is significantly reduced.
5. Repair Costs: The final diminished value never exceeds repair costs.

Step-by-Step Guide: How to Use the Calculator

Here’s how you can calculate diminished value with the tool:

1. Enter Pre-Accident Value
   • Input your car’s estimated market value before the accident (based on Kelley Blue Book or dealer quotes).
2. Enter Repair Costs
   • Type in the total repair expenses (from invoices or insurance estimates).
3. Enter Vehicle Age
   • Provide the car’s age in years.
4. Select Damage Severity
   • Choose between Minor, Moderate, or Major damage.
5. Select Salvage Status
   • Indicate whether the car was declared Salvaged/Rebuilt or Not Salvaged.
6. Click “Calculate”
   • The tool processes your inputs, shows a progress bar, and displays your estimated diminished value.
7. Review Your Results

Example Calculation

Let’s walk through a real-world scenario:

• Pre-Accident Value: $25,000
• Repair Cost: $5,000
• Vehicle Age: 3 years
• Damage Severity: Moderate
• Salvaged: No

Step 1: Base Loss = 10% of $25,000 = $2,500
Step 2: Severity Multiplier (Moderate) = 0.50 → $2,500 × 0.50 = $1,250
Step 3: Age Multiplier = 1 – (0.01 × 3) = 0.97 → $1,250 × 0.97 = $1,212.50
Step 4: Salvage Status = No adjustment
Step 5: Compare with Repair Cost = $5,000 → Final DV = $1,212.50

👉 Estimated Diminished Value: $1,212.50

This estimate shows that even though repairs were $5,000, the actual lost resale value is around $1,200.
