Formula Used

The estimated value is calculated using the following formula:

Estimated Value = (Base Value × Age Factor × Mileage Factor × Condition Factor) × Market Adjustment

Where:

Base Value - The average market value for the specific car model
Age Factor - Adjustment based on the car's age (newer cars have higher values)
Mileage Factor - Adjustment based on the car's mileage (lower mileage = higher value)
Condition Factor - Adjustment based on the car's reported condition
Market Adjustment - Regional market trends and demand factors

Note: This is an estimate only. Actual CarMax offer may vary based on additional factors not included in this calculation.

Worked Example

Let's calculate the estimated value for a 2018 Toyota Camry with 35,000 miles in Good condition.

Base Value for 2018 Toyota Camry: $18,500
Age Factor (2018): 0.92
Mileage Factor (35,000 miles): 0.88
Condition Factor (Good): 0.90
Market Adjustment: 1.05

Estimated Value = ($18,500 × 0.92 × 0.88 × 0.90) × 1.05 Estimated Value = $18,500 × 0.72528 × 1.05 Estimated Value = $18,500 × 0.761536 Estimated Value = $14,000

Based on these factors, the estimated value for this 2018 Toyota Camry would be $14,000.
