AUTO CALCULATOR
Car Depreciation Calculator
Estimate how much value a vehicle has lost and project its future value based on an estimated annual depreciation rate.
The projection uses compound annual depreciation from the current vehicle value. Actual depreciation varies by vehicle and market.
What Is Car Depreciation?
Car depreciation is the reduction in a vehicle's value over time. Unlike many investments that may increase in value, most new vehicles lose value as they age and accumulate mileage.
Depreciation is one of the largest costs of vehicle ownership, even though it does not require a direct payment each month.
How Is Car Depreciation Calculated?
A simple way to measure depreciation is to compare the original purchase price with the vehicle's current value.
Depreciation = original price − current value
The percentage depreciation can be calculated as:
Depreciation % = depreciation ÷ original price × 100
Car Depreciation Example
Suppose a vehicle originally cost $35,000 and is currently worth $28,000.
The value lost is:
$35,000 − $28,000 = $7,000
The percentage depreciation is approximately:
$7,000 ÷ $35,000 × 100 = 20%
Therefore, the vehicle has lost approximately 20% of its original value.
Projecting Future Car Value
This calculator can also estimate a vehicle's future value using an estimated annual depreciation rate.
The projection uses compound depreciation, meaning the estimated depreciation is applied to the vehicle's value each year.
Future value = current value × (1 − depreciation rate)ⁿ
In this formula, n represents the number of years in the projection.
What Causes a Car to Depreciate?
Many factors can affect how quickly a vehicle loses value, including:
- Vehicle age
- Mileage
- Make and model
- Vehicle condition
- Accident history
- Maintenance history
- Market demand
- Number of previous owners
New Cars vs. Used Cars
New vehicles often experience significant depreciation during the early years of ownership. Once a vehicle becomes older, the rate of depreciation can change depending on the vehicle and market.
Used vehicles can therefore have different depreciation patterns from newer vehicles.
Why Mileage Matters
Mileage is an important factor when determining the market value of a used vehicle. Higher mileage can reduce resale value because buyers may expect greater wear and future maintenance requirements.
However, mileage is only one factor. Vehicle condition, maintenance, model popularity, and market conditions can also have a significant effect on value.
Car Depreciation and Total Cost of Ownership
Depreciation is an important part of the total cost of owning a vehicle. Other costs can include financing, fuel, insurance, maintenance, repairs, taxes, and registration.

Frequently Asked Questions
How much does a car depreciate each year?
Depreciation varies considerably by vehicle, age, mileage, condition, and market demand. This calculator lets you choose an estimated annual depreciation rate for a future-value projection.
How do I calculate how much value my car has lost?
Subtract the vehicle's current value from its original purchase price. The difference represents the estimated dollar amount of depreciation.
What is a good depreciation rate for a car?
There is no single depreciation rate that applies to every vehicle. Different makes, models, ages, mileage levels, and market conditions can produce very different results.
Do all cars depreciate at the same rate?
No. Depreciation varies by vehicle and can be influenced by reliability, demand, mileage, condition, age, and other market factors.
Does mileage affect car depreciation?
Yes. Mileage can affect a vehicle's resale value because higher mileage generally indicates greater use and potential wear.
Is the future value estimate exact?
No. The projection is an estimate based on the annual depreciation rate you enter. Actual vehicle values depend on market conditions, vehicle condition, mileage, and other factors.
