Depreciation, the drop in a car's value over time, is usually the single biggest cost of car ownership, often outweighing fuel, insurance, and servicing combined. Understanding how it works can save you a significant amount of money over the life of a car.
Why cars lose value
New cars typically lose a large share of their value in the first few years, with the steepest drop often happening the moment a car is first registered and driven away. After that, depreciation continues but usually slows, tapering off as the car ages and its resale value settles closer to what similar used examples are worth.
Several factors influence how fast a specific car depreciates: brand and model reputation for reliability, how popular that car is on the used market, mileage, condition, service history, and even colour can all play a part.
What affects the rate
- High mileage and heavy wear accelerate depreciation beyond the average for that model.
- A poor or incomplete service history makes buyers wary and pushes resale value down.
- Popular, sought-after colours and specifications tend to hold value better than unusual choices.
- Models with a reputation for reliability and low running costs typically depreciate more slowly.
- Damage history, even if repaired well, can reduce what buyers are willing to pay.
Using this to your advantage
Buying a car that's two or three years old often means someone else has absorbed the steepest part of the depreciation curve, while you still get a relatively young, well-equipped car. Keeping full service history, maintaining the car well, and choosing a popular colour and specification when buying new can all help protect resale value later.
It's also worth thinking about how long you plan to keep a car before you buy it. Selling after only a year or two, right in the steepest part of the depreciation curve, tends to cost you more than holding onto a car for several years and letting the rate of loss slow down.
Depreciation is unavoidable, but it isn't random. By understanding what drives it and buying, maintaining, and timing your sale with that in mind, you can keep considerably more of your money over the years you own a car.
