Why Knowing Your Car’s Value Matters
Understanding your car’s current worth is essential for several reasons:
- Negotiating trade-ins or sales: Ensures you get a fair price from dealerships or private buyers.
- Financial planning: Helps you budget for your next vehicle purchase.
- Insurance purposes: Determines accurate coverage and premiums.
- Avoiding over- or underpricing: Helps prevent financial loss when selling.
Car values fluctuate based on age, mileage, and condition, and having a reliable estimate can prevent you from being underpaid or overpaying for your next car.
How the CarMax Value Calculator Works
This calculator uses a combination of key factors to estimate your vehicle’s value:
- Car Year (Age): Older cars typically depreciate faster.
- Mileage: Higher mileage reduces value due to wear and tear.
- Condition: Better-maintained cars retain higher resale value.
- Original Price: The starting point for calculating depreciation.
The formula behind the calculation considers:
- 5% depreciation per year
- 3% depreciation per 20,000 miles
- Adjustment based on car condition (0–100%)
By combining these factors, the calculator provides a realistic estimate of your car’s current market value.
How to Use the CarMax Value Calculator

Step 2: Input Mileage
Add the total miles driven. Mileage directly impacts your car’s depreciation.
Example: 45,000 mi
Step 3: Specify Car Condition
Rate your car’s condition on a scale of 0–100%, with 100% being perfect condition.
Example: 90%
Step 4: Original Price
Enter the original purchase price of your car. This is crucial for calculating depreciation accurately.
Example: $25,000
Step 5: Calculate
Click the “Calculate” button. The estimated CarMax value will appear instantly, formatted for readability.
Step 6: Reset (Optional)

Example Calculation
Suppose you have a car with the following details:
- Year: 2018
- Mileage: 40,000 mi
- Condition: 85%
- Original Price: $28,000
Step 1: Calculate age factor:
2026 – 2018 = 8 years → 8 × 5% = 40% depreciation
Step 2: Calculate mileage factor:
40,000 ÷ 20,000 × 3% = 6% depreciation
Step 3: Adjust for condition:
85% of original price
Step 4: Compute estimated value:
$28,000 × 0.85 × (1 – 0.40 – 0.06) = $28,000 × 0.85 × 0.54 ≈ $12,852
The estimated CarMax value of the vehicle is $12,852.
