Understanding Car Depreciation

Car depreciation is the decline in a vehicle's value over time. From the moment you drive a new car off the dealership lot, its market value begins to fall. Understanding this rate of decay is crucial for budgeting, resale planning, and evaluating lease versus buy decisions.

Depreciation Formula and Method

This calculator employs the declining balance method, which is the standard model for passenger vehicles. The value at the end of any given year is calculated as:

Where:

• $V_t$ is the vehicle value at year $t$.
• $V_{t-1}$ is the vehicle value in the preceding year.
• $d$ is the annual depreciation rate (expressed as a decimal).

The total accumulated depreciation over $n$ years is calculated by subtracting the final residual value from the initial purchase price:

Where $V_0$ is the initial purchase price, and $V_n$ is the value at the end of the holding period.

Factors Influencing Depreciation Rates

While all cars lose value, the speed at which they do varies based on:

• Vehicle Class: Trucks and SUVs often hold value longer than sedans, while electric vehicles (EVs) currently experience faster depreciation due to rapid battery tech advancements.
• Mileage: High annual mileage accelerates value loss. Our tool adjusts the base rate by adding 0.5% for every 1,000 miles driven above the standard 12,000 miles per year.
• Condition and History: Consistent maintenance records and a clean accident report help preserve residual value.
