A new car loses value the moment you drive it off the lot — and that silent loss is often bigger than your monthly payment, fuel, and insurance combined. This car depreciation calculator estimates how much value your vehicle loses each year, what it will be worth at any point during ownership, and how much money you have effectively "burned" by the time you sell or trade it in.
Depreciation is the single largest cost of owning a car. According to industry estimates, the average new vehicle can lose roughly 20% of its value in the first year and around 15% in each following year. By the end of year five, many cars are worth only 40–60% of what you paid. Adjust the inputs below and watch the resale value and cumulative loss update instantly.
How to Use
- Enter the Purchase Price — the amount you actually paid for the vehicle, including any down payment. This is the starting point for every calculation.
- Set the Salvage / Residual Value — the estimated worth of the car at the end of its useful life. For a typical family sedan this is $3,000–$6,000; leave it low for budget cars and higher for luxury or classic models.
- Choose the Useful Life in years. Five years is the most common ownership horizon, but you can use three if you lease and seven if you keep vehicles long-term.
- Pick a Depreciation Method. Declining-balance (200%) mirrors real-world car values, which drop fastest when the car is new and flatten out later. Straight-line spreads the loss evenly each year and is commonly used for accounting and tax records.
- Set the Ownership Year to Evaluate — the specific year at which you want to know the car's current resale value. Enter 0 for a brand-new car, 3 after three years of ownership, and so on.
The result card then shows the year-one depreciation, the loss during the evaluated year, the estimated resale value (highlighted), and the total value lost since purchase. A year-by-year schedule lets you see the full curve.
The Two Depreciation Methods
Declining-balance (realistic car curve) assumes the car depreciates by a percentage of its remaining value each year, with a steeper hit when new:
resaleValue(y) = purchasePrice × (1 − rate₁) × (1 − rate₂) × … × (1 − rate_y), floored at the salvage value
where the rates are about 25% in year one, 15% in year two, and 10% in each later year.
On a $35,000 car, the calculator applies a realistic used-car curve: about 25% loss in year one, 15% in year two, and 10% in each later year. Year one loses 25% of $35,000 ($8,750), leaving $26,250; year two loses 15% ($3,938), leaving $22,313; year three loses 10% of the remaining value, leaving roughly $20,081. This front-loads the loss, which is exactly what the used-car market does.
Straight-line spreads the loss evenly:
annualDepreciation = (purchasePrice − salvageValue) ÷ usefulLifeYears
On the same $35,000 car with a $5,000 salvage value over five years, the annual loss is a constant $6,000. This method never surprises you, but it understates the true first-year hit a new car actually takes.
Examples
Example 1 — A typical sedan. You buy a car for $35,000, set a $5,000 salvage value, a five-year life, and use declining-balance. At year three the resale value is $20,081, the loss in that year is $2,231, and the total value lost since purchase is $14,919 — meaning the car you paid $35,000 for has already lost a substantial chunk of its value three years in.
Example 2 — Switching to straight-line. Keep the same $35,000 price, $5,000 salvage, and five-year life, but select straight-line. Each year the car loses a flat $6,000, so at year three its book value is $17,000 with $18,000 lost in total. Notice how much gentler the early years look compared with the declining-balance curve — which is why accountants like it and buyers are shocked by the real market.
Example 3 — Brand-new vs. three years in. Set the ownership year to 0 and the resale value equals your $35,000 purchase price with $0 lost. Slide the year to 3 and, under declining-balance, roughly $14,919 has vanished. That gap is the real cost of new-car ownership — often larger than fuel, insurance, and maintenance combined.
Example 4 — A high-value vehicle. A $1,200,000 supercar with a $200,000 salvage value over a seven-year life uses the same declining-balance curve. At year three the resale value is roughly $688,500, a single-year loss near $76,500, and a cumulative loss of about $511,500. The engine handles seven-figure purchase prices without overflow, so you can model everything from a $25,000 commuter to a collector car.
FAQ
How much does a new car depreciate in the first year?
On average, a new car loses about 15–25% of its value in the first year after purchase. This calculator uses that realistic first-year hit (25% of the purchase price) — which reflects the real "new-car premium" you pay the moment you own the vehicle instead of the dealer.
What is the difference between straight-line and declining-balance depreciation?
Straight-line depreciation divides the total loss evenly across every year, so the same dollar amount is lost annually. Declining-balance applies a fixed percentage to the car's remaining value each year, so the biggest losses happen early and shrink over time. Declining-balance matches how cars actually lose value in the resale market, while straight-line is simpler for accounting and tax records.
How do I calculate what my car will be worth after 5 years?
Enter your purchase price, set a realistic salvage value and useful life, choose declining-balance, and set the ownership year to 5. The resale value shown is your estimated worth after five years of ownership. As a rule of thumb, most cars retain roughly 40–60% of their original value by year five.
Why do cars lose value so fast when new?
New cars carry a premium that vanishes the moment they leave the dealership because the buyer now owns a "used" vehicle, even if it has only miles on the odometer. Dealers also discount new cars heavily near year-end, which resets the market value of every similar used car. Depreciation slows sharply after years three or four.
Should I buy new or used to avoid depreciation?
Buying a used car that is two to three years old lets someone else absorb the steepest early depreciation. A car that loses $14,000 in its first year costs its second owner almost nothing in that initial hit. If you keep the car for many years, the advantage of buying used shrinks, but the first owner always pays the largest depreciation bill.
Does leasing avoid depreciation?
No — leasing does not avoid depreciation; it just hides it. Your lease payment is largely the depreciation the finance company expects over the contract term, plus interest and fees. Checking this calculator against your lease's residual value shows exactly how much of your monthly payment is paying for value the car will never have again.
