Car Depreciation Explained: Why Cars Lose Value and How to Slow It

Depreciation is the value a car loses over time, and for most owners it is the single biggest cost of running a car. The steepest fall usually comes in the first few years, then it slows. You cannot stop it, but you can slow it by choosing the right car, keeping a full service history and looking after the condition.

What is car depreciation?

It is the difference between what you pay for a car and what it is worth when you sell or part exchange it. It does not show up as a bill, which is why it is easy to overlook, but it is real money lost.

When does a car lose the most value?

Most cars lose value fastest when they are new, and the rate slows as they get older. That is why a car of a few years old can be good value: the first owner has already taken the biggest hit. Our guide to nearly new versus three-year-old cars looks at this in more detail.

What makes some cars depreciate faster than others?

• Demand. Popular, practical models with wide appeal tend to hold their value better.

• Reliability and running costs. Cars known for being dependable and cheap to keep usually stay in demand.

• Mileage. Higher mileage than average for the age usually means a lower value.

• Condition and history. Damage, worn interiors and gaps in the service record all cut the price.

• Fuel type and rules. Changes in tax, clean air zones and fuel prices shift demand between petrol, diesel, hybrid and electric.

• Specification and colour. Useful equipment helps. Unusual colours or heavy modifications can narrow the pool of buyers.

• New model launches. When a replacement model arrives, the outgoing one can drop in value.

How can I slow depreciation?

1. Buy a car that is a few years old. You avoid the steepest part of the fall.

2. Keep a full service history. Service on time and keep every receipt. Our guide to full versus part service history explains why it matters at resale.

3. Look after the condition. Fix chips, scuffs and kerbed wheels early, and keep the interior clean.

4. Keep mileage sensible. If you cover big distances, choose a car that suits high mileage.

5. Avoid heavy modifications. They rarely add value and can put buyers off.

6. Sell at the right time. Selling before a big job, such as a timing belt change, is due can help.

Do electric cars depreciate faster?

Some early electric cars did lose value quickly, and used electric prices have moved around as the market has grown. Battery health is now one of the biggest factors in a used electric car's value. Our guides to whether electric cars hold their value and checking EV battery health explain more.

Can depreciation work in my favour?

Yes, if you are buying. Choosing a well-kept used car means someone else has paid for the steepest drop, so you get more car for your money. Our guide to which cars hold their value best gives examples.

Common questions

Which cars hold their value best?

Usually popular, reliable models with low running costs and broad appeal. Demand changes over time, so check current values before you buy.

Does colour affect resale value?

It can. Mainstream colours appeal to more buyers, while unusual shades can take longer to sell. Our guide to car colours and resale covers this.

Does servicing at an independent garage hurt resale value?

Not if the work follows the manufacturer's schedule and uses suitable parts. What matters is that the history is complete and documented.
