There is no single average car depreciation rate that applies to every used car. Annual value loss depends on the vehicle, its starting age, mileage, condition, and local market. Calculate dollar depreciation by subtracting ending value from starting value. Divide that loss by starting value and multiply by 100 for the percentage loss. For example, a decline from $18,000 to $15,300 is $2,700, or 15%, in a hypothetical year.

Understanding annual vehicle value loss
One of the biggest costs of owning a vehicle is something you may never receive a bill for: depreciation.
If you buy a used car for $20,000 and later sell it for $15,000, the vehicle has lost $5,000 in value. This difference can significantly affect the true cost of ownership, even if the car has been reliable and inexpensive to maintain.
But how much does a used car depreciate per year, and how can you estimate its future resale value?
The answer depends on the make, model, mileage, condition, age, local demand, and wider vehicle market. There is no single depreciation rate that accurately applies to every used car.
This guide explains annual car depreciation, provides practical calculation examples, and shows how to compare vehicle values before buying or selling.
What Is Car Depreciation?
Car depreciation is the decrease in a vehicle's market value over time.
For example, imagine buying a used vehicle for $18,000. After three years, comparable vehicles in similar condition sell for approximately $12,000.
Your estimated depreciation is:
$18,000 − $12,000 = $6,000.
Over the three-year ownership period, the car has lost approximately one-third of its original purchase value.
Depreciation matters because a vehicle is not simply an expense you pay for once. Its remaining resale value determines how much of your purchase cost you can recover when you sell it.
A vehicle that retains value relatively well may be less expensive to own than another car that costs less initially but loses value faster.
However, depreciation is only one component of ownership cost. Fuel, insurance, repairs, financing, registration, and taxes also matter.
How Much Does a Used Car Depreciate Per Year?
Used-car depreciation varies substantially by vehicle and market.
A commonly observed pattern is that many new vehicles experience significant depreciation during their early years. A used-car buyer may therefore avoid some of the initial value loss by purchasing a vehicle that is several years old.
However, buying used does not automatically guarantee slower depreciation. Older luxury vehicles, models with expensive repairs, vehicles affected by changing demand, and cars with poor condition records may still lose value quickly.
When researching annual depreciation, consider three different measurements:
These measurements answer slightly different questions and should not be confused.
For a specific vehicle, actual historical prices and comparable listings are more useful than assuming an industry-wide percentage.
- Dollar depreciation: The amount of value lost during a period.
- Percentage depreciation: The loss relative to the vehicle's starting value.
- Annualized depreciation: The equivalent yearly rate for a change observed over multiple years.

Car depreciation calculator What is my car worth?How to Calculate Car Depreciation Per Year
The basic depreciation formula is:
Depreciation = Starting Vehicle Value − Ending Vehicle Value
To calculate the total percentage loss:
Depreciation (%) = [(Starting Value − Ending Value) ÷ Starting Value] × 100
Suppose you buy a car for $18,000 and estimate that its value will be $15,300 one year later.
First, find the difference:
$18,000 − $15,300 = $2,700.
Next, divide by the starting value:
$2,700 ÷ $18,000 = 0.15.
Multiply by 100:
0.15 × 100 = 15%.
The vehicle would lose 15% of its starting value in that hypothetical year.
This is an illustration, not a verified average depreciation rate for all used cars.
How to Calculate Average Annual Depreciation
Suppose a vehicle is purchased for $18,000 and sold three years later for $12,000.
Total value lost = $6,000.
Simple average annual dollar depreciation:
$6,000 ÷ 3 = $2,000 per year.
The total percentage loss is:
($6,000 ÷ $18,000) × 100 = 33.33%.
Dividing this percentage by three gives approximately 11.11 percentage points of the original value per year. However, this is not the same as a compound annual depreciation rate.
To calculate the equivalent compounded annual decline, use:
Annualized Depreciation Rate = [1 − (Ending Value ÷ Starting Value)^(1 ÷ Years)] × 100
For this example:
[1 − (12,000 ÷ 18,000)^(1 ÷ 3)] × 100 ≈ 12.64%.
The equivalent compounded annual depreciation rate is approximately 12.64%.
This distinction matters when comparing cars over different ownership periods.
Use a starting value greater than zero, an ending value of zero or more, and an ownership period greater than zero. The annualized rate is an equivalent constant decline; it does not mean the vehicle lost that percentage in every actual year. A higher ending value produces a negative depreciation rate, indicating appreciation.
Illustrative Five-Year Used Car Depreciation Example
Consider a used vehicle with a current value of $25,000.
For illustration, assume its value declines by 18% during the next year and 12% in each following year.
After five years, the model projects approximately $12,706 in value loss.
The vehicle would retain approximately 49.2% of its initial modeled value.

What Factors Affect Used Car Depreciation?
1. Vehicle Age
Age influences resale value because buyers generally pay more for a newer model when the vehicles are otherwise comparable.
However, age alone does not predict the rate of value loss. Two vehicles manufactured in the same year can have very different resale values.
2. Mileage
Higher mileage may suggest greater wear, possible component replacement needs, or reduced remaining warranty coverage.
A vehicle with documented maintenance and reasonable mileage may attract stronger resale interest than a similar vehicle with significantly higher mileage and incomplete records.
3. Reliability and Maintenance
Buyers often consider the expected cost and reliability of future ownership.
A car with a complete maintenance history, properly completed repairs, and no unresolved safety concerns may be more attractive than one with substantial neglected maintenance.
4. Accident and Damage History
Previous collisions, flood exposure, structural repairs, and title problems can affect market value.
Even when repairs have been completed, buyers may discount vehicles with significant damage histories.
A vehicle history report is useful but should be combined with an independent physical inspection.
5. Fuel Economy and Vehicle Type
Consumer preferences can change as fuel prices, regulations, and technology evolve.
Demand may differ among petrol, diesel, hybrid, and electric vehicles, as well as SUVs, sedans, pickup trucks, and smaller cars.
6. Local Market Conditions
Used-car prices are influenced by local supply, seasonal demand, financing conditions, and the availability of new vehicles.
A model that sells quickly in one region may face weaker demand elsewhere.
For this reason, local comparable listings should be part of any resale value estimate.
Do Used Cars Depreciate Slower Than New Cars?
Often, but not always.
New cars can lose significant value early in their ownership life because buyers may be unwilling to pay the same amount for a vehicle that is no longer new.
A used car purchased after that initial period may have a smaller remaining value to lose.
Buying after an earlier value decline means using the current purchase value as your starting point. It does not establish what the vehicle will be worth when you sell it.
However, a used vehicle can still experience significant depreciation if its condition deteriorates, repair costs increase, or market demand weakens.
The important comparison is not simply new versus used. It is the total cost of owning specific vehicles for your expected period of use.
How Does Depreciation Affect a Car Loan?
Vehicle value and loan balance are separate measurements.
Your car can lose market value while you gradually repay the loan principal.
If your outstanding loan balance exceeds what the vehicle could sell for, you have negative equity.
For example, suppose you owe $17,000 on a car currently worth approximately $14,000.
Your estimated negative equity is:
$17,000 − $14,000 = $3,000.
This can complicate selling or trading the vehicle before the loan is paid off.
A substantial down payment and a shorter repayment period can help reduce negative-equity exposure, although neither eliminates it.
Use the Car Loan Calculator to compare loan balances and repayment assumptions.
How to Reduce Depreciation Losses
You cannot control every change in the used-car market, but you can make purchasing and ownership decisions that may help protect resale value.
First, research several comparable vehicles before buying. Compare model year, trim, mileage, condition, and local asking prices.
Second, obtain an independent pre-purchase inspection. Unexpected mechanical problems can be expensive and may also affect resale value.
Third, follow the manufacturer's maintenance schedule and retain service records.
Fourth, avoid unnecessary modifications that make a car less appealing to future buyers.
Fifth, keep the vehicle in good condition. Address fluid leaks, warning lights, damaged tires, and other mechanical problems promptly.
Finally, estimate the vehicle's likely value when you plan to sell it. A cheap purchase price is not necessarily a good deal if the vehicle is expected to require major repairs or lose substantial resale value.
How to Estimate Future Resale Value
Start with the vehicle's current market value, rather than automatically using its original new-car price.
Then compare listings for similar vehicles that are older or have mileage matching your expected future ownership period.
For example, if you plan to keep a used car for three years and drive approximately 12,000 miles annually, examine comparable models that are three years older and have roughly 36,000 more miles.
Adjust your expectations for condition, trim, accident history, and local market differences.
Remember that advertised prices are asking prices. They do not necessarily equal completed sale prices.
For planning, calculate optimistic, middle, and conservative depreciation scenarios instead of relying on a single estimate.

Frequently Asked Questions
What is the average car depreciation per year?
There is no reliable universal percentage for every used car. Annual depreciation depends on the vehicle, starting age, mileage, condition, and market. Research comparable vehicles to develop a more useful estimate.
How much value does a car lose in five years?
The amount varies widely. You can model five-year value changes using estimated annual decline rates, but the result should not be treated as a guaranteed resale value.
How do I calculate depreciation on a used car?
Subtract the vehicle's estimated ending value from its starting value. Divide the difference by the starting value and multiply by 100 to determine the total percentage loss.
Can a used car increase in value?
Yes. Certain vehicles may appreciate because of rarity, collectible demand, or unusual market conditions. However, appreciation should not be assumed for an ordinary used vehicle.
Does high mileage always mean high depreciation?
Not necessarily. Mileage is important, but reliability, maintenance history, age, condition, and model demand also affect resale value.
Is depreciation included in monthly car payments?
No. A car payment includes repayment of borrowed principal and financing costs. Depreciation is the change in the vehicle's market value.
Final Thoughts
Understanding how much a used car depreciates per year can help you avoid focusing only on the purchase price.
A vehicle that loses less value may provide better overall ownership economics, but depreciation must be considered alongside repair costs, fuel, insurance, and financing.
Use actual market comparisons, evaluate multiple depreciation scenarios, and inspect any vehicle carefully before committing to a purchase.
