Your vehicle loses value the moment you drive it off the lot. This depreciation is one of the biggest costs of car ownership, and it's completely normal.
Why Cars Depreciate
Depreciation happens because:
- Age matters most: A car loses about 20% of its value in year one, then continues declining each year
- Mileage adds up: Every mile driven reduces resale value
- Wear and tear: Interior damage, mechanical issues, and cosmetic problems lower worth
- Market demand shifts: Certain models, colors, and features are more popular than others
- Technology gets outdated: Older safety features and infotainment systems become less desirable
In fact, vehicle ownership costs have grown dramatically. According to the Department of Transportation, the average car cost $12,296 to own in 2024 (in January 2026 dollars), compared to just $2,154 in 1975. Depreciation, insurance, and fuel make up about 69% of your annual ownership costs.
What Affects Your Car's Value
Depreciation isn't the same for every vehicle. Your specific situation depends on:
- Vehicle condition: Mechanical problems and accident history tank value
- Service history: Well-maintained cars hold value better
- Local market: Supply and demand in your area matter
- Model popularity: Some makes and models retain value longer
- Fuel efficiency trends: Rising gas prices boost demand for efficient vehicles
For example, electric vehicles cost about $10,682 per year to own on average, which is more than comparable gas cars upfront. However, EV owners who charge at home and keep their vehicle for five years can reach cost parity with gas SUVs within three to five years.
Steps to Protect Your Car's Value
While you can't stop depreciation, you can minimize it:
- Keep up with maintenance: Regular oil changes and repairs prevent bigger problems
- Drive less: Lower mileage means higher resale value
- Maintain the interior and exterior: Clean, damage-free cars sell for more
- Keep service records: Buyers trust documented maintenance
- Avoid accidents: Any accident history significantly reduces value
Understanding depreciation helps you make smarter decisions about when to trade in, sell privately, or keep your car longer. Sidekick tracks your vehicle's maintenance and condition, which helps protect its long-term value.
The Bottom Line
Your car is worth less because depreciation is built into vehicle ownership. Focus on maintenance and keeping your car in good condition to preserve as much value as possible for when you eventually sell or trade it in.
