What the Calculator Inputs Mean
Cars lose value the moment they leave the lot — and for most households, a vehicle is the second-largest purchase they will ever make. Understanding how depreciation works, how to predict it, and how it affects the real cost of ownership can save thousands of dollars in buying, selling, and leasing decisions. The car depreciation calculator quantifies what your intuition already suspects: some vehicles lose value at a fraction of the rate of others.

Kelley Blue Book and Edmunds provide real-time market values based on actual sales data. Enter your vehicle’s specifics to see both private party and dealer trade-in values — these represent the actual depreciation your specific vehicle has experienced, not a theoretical average.
How Depreciation Is Calculated
- Year 1: Most vehicles lose 15-25% of their value — the steepest drop occurs in the first 12 months
- Years 2-5: Depreciation continues at 10-15% per year for most vehicles
- Years 6-10: Depreciation slows to 5-10% annually as the vehicle approaches stable older-car value
- Luxury vehicles depreciate faster than average in early years
- Trucks and SUVs depreciate more slowly than sedans in most market conditions
