Vehicle Depreciation Calculator

The Formula

Vehicle depreciation is modeled year-by-year using typical depreciation rates that decline over time (new vehicles depreciate fastest in year 1, slowing as the vehicle ages).

Variable Definitions

How to Use This Calculator

1. 1

   Enter the original vehicle purchase price.

2. 2

   Enter the current age of the vehicle (0 for brand new).

3. 3

   Enter how many years you plan to own it.

4. 4

   Select the vehicle type for appropriate depreciation rates.

5. 5

   Review the total depreciation cost, annual average, and monthly cost to understand the true ownership expense.

Common Applications

• Estimating a vehicle resale value before trading in or selling, to negotiate a fair price with dealers
• Comparing total ownership costs between new and used cars by projecting depreciation over planned ownership years
• Deciding between vehicle types (truck vs luxury vs EV) based on how well each retains value over time
• Budgeting for the true monthly cost of car ownership including depreciation, not just loan or lease payments

Vehicle depreciation — value drops steepest in the first year then slows

Understanding the Concept

DepreciationThe decrease in an asset's value over time due to wear, age, or obsolescence. Used in tax calculations and financial reporting. is the single largest cost of vehicle ownership — often exceeding fuel, insurance, and maintenance combined. A new $40,000 car loses $6,000 to $8,000 in its first year. Over 5 years, a typical car loses 40 to 60 percent of its value. This is why financial advisors often recommend buying 2 to 3 year old used vehicles — someone else has absorbed the steepest depreciation, but the vehicle still has most of its useful life remaining. Real-world example: buying a $45,000 luxury sedan and owning it for 5 years. Using luxury depreciation rates, the car loses 25 percent ($11,250) in year one, then 20 percent of the remaining value in year two ($6,750), and so on. After 5 years, the car is worth approximately $14,000 — a loss of $31,000, or $6,200 per year. That is $517 per month in depreciation alone, more than many car payments. The same $45,000 spent on a Toyota Tacoma (truck rates) retains roughly $21,000 after 5 years. The difference of $7,000 in retained value highlights how vehicle choice dramatically impacts total ownership cost. For EV buyers, rapid battery technology improvements and government incentive eligibility for new EVs create additional downward pressure on used EV prices beyond standard depreciation rates.
