Understanding Car Depreciation

Car depreciation is the difference between the amount you spent when you bought your vehicle and the amount you can get when you sell or trade it in. It is typically the largest cost of car ownership, often exceeding fuel, insurance, or maintenance expenses.

How We Calculate Your Car's Value

Our calculator uses a tiered depreciation model. Generally, a new car loses about 20% of its value in the first year and roughly 15% each year thereafter. However, the specific type of vehicle and its condition significantly impact these rates.

  • Luxury Vehicles: Often depreciate faster (up to 20-25% annually) due to high maintenance costs for second-hand owners.
  • Trucks and SUVs: Historically hold their value better due to durability and consistent market demand.
  • Condition: Mechanical issues or cosmetic damage can accelerate value loss by 5% to 30%.

Real-World Example

If you purchase a Standard Sedan for $30,000 and keep it for 3 years in Good condition:

  • Year 1: Value drops to approximately $24,000 (20% loss).
  • Year 2: Value drops to approximately $20,400 (additional 15% loss).
  • Year 3: Value drops to approximately $17,340 (additional 15% loss).

In this scenario, you have "spent" $12,660 just in lost value over three years, or roughly $351 per month.

How to Minimize Depreciation

While you cannot stop depreciation entirely, you can slow it down. Maintain a detailed service record, keep the mileage below the national average (approx. 12,000 – 15,000 miles per year), and choose popular colors like silver, white, or black which are easier to resell. Additionally, purchasing a "certified pre-owned" vehicle allows the first owner to take the largest depreciation hit (the first-year 20% drop), saving you thousands.
