How much does mileage affect car value?

While many variables contribute to a car’s worth on the resale market, mileage often takes the spotlight.

Higher mileage generally means a lower price. On average, you can expect a 20% drop in car value for every 20,000 miles driven.

That said, there are exceptions. Whether you’re buying or selling your car to a dealer or a private buyer, mileage will probably be one of the first things you’re asked about because it’s closely linked to the overall condition of the car.

Understanding how mileage affects your car’s value helps you make better decisions, whether you’re planning to sell now or later.

Key Takeaways

Depreciation Rate: Expect a car’s value to drop by approximately 20% for every 20,000 miles driven.
UK Average: The typical UK car covers 7,500 to 8,000 miles per year; exceeding 12,000 miles often triggers higher finance charges.
Maintenance vs. Mileage: A high-mileage car with a full service history can be more valuable than a low-mileage car that has been neglected.
Critical Milestones: Major components like timing belts and water pumps typically require replacement between 50,000 and 100,000 miles.
Longevity: With proper care, modern vehicles can last well beyond 100,000 miles, sometimes reaching up to 300,000 miles.

Why is car mileage so important?

*Mileage is one of the key factors determining your car’s resale price.*

Mileage matters because it’s one of the quickest ways to gauge how much life a car has left. It acts as a key indicator of overall condition, helping buyers and dealers estimate potential wear-and-tear and future servicing needs.

Lower mileage generally suggests better condition and reliability. Cars with less mileage are more likely to get better prices on the resale market, but this is by no means guaranteed. Excessively low mileage can indicate prolonged periods of inactivity, which can lead to its own set of issues.

When buying or selling used cars, it’s essential to take mileage into account. Two cars can be completely identical in make, model, and age, but differences in mileage could make one worth more than the other. Other factors matter too, including accident history, overall condition, and market demand for that make and model.

However, cars with well-documented maintenance records and proper care can still offer excellent reliability and performance, even with higher mileage.

How does mileage affect your car’s parts?

As the odometer ticks higher, the impact of mileage affects individual car components differently. While some parts wear more rapidly, others remain resilient. Here’s a quick breakdown:

Engine – High mileage increases strain on pistons, cylinders, and valves, potentially affecting engine performance and efficiency over long amounts of time.
Transmission – Frequent use can wear down gears and seals, leading to shifting issues and fluid leaks.
Suspension – Components like shocks and struts may degrade over time, affecting ride comfort and handling.
Body – Higher mileage cars may exhibit cosmetic wear, such as paint fading or rust, both of which impact aesthetics and resale value.
Tyres – Tyres lose their grip over time, reducing performance and overall vehicle safety.

As a rule of thumb, some car components should be changed after hitting certain mileage markers. This includes the following (these are rough estimates and can vary by make, model, and driving conditions):

What’s good mileage for a car?

In the UK, the average car covers between 7,500 and 8,000 miles per year, according to data from the Department of Transport. However, this can vary depending on what kind of driving you do, as well as how well you maintain your car.

Car-buying dealers and financing companies know this and many finance plans assume a yearly mileage of 8,000 to 10,000. Financiers often charge more for mileage that exceeds 12,000 per year.

You can estimate if your car’s mileage is low, high, or average for its age with some quick maths.

Take 10,000 miles as the yearly average for a bit of wiggle room and multiply it by the car’s age. The result is the rough expected mileage for a car that old. Compare that number to the mileage on your odometer to see if you’re under or over.

Here’s a quick reference (these are rough estimates and actual figures can vary):

The type of fuel you use can also impact mileage. Diesel cars, for example, tend to have higher mileage given their superior fuel economy while driving long distances. Company cars also rack up mileage more easily, so their average mileage shouldn’t be judged as if they were a normal passenger car.

How much does mileage affect car price?

how much does mileage affect price? — *Every 20,000 miles on your odometer roughly equates to your car value depreciating by 20%.*

It can be hard to pinpoint the exact price difference caused by mileage alone. Other factors such as plate changes, cosmetic wear, local demand due to laws like the ULEZ, and general wear and tear all contribute to car depreciation.

As a general rule, increases in mileage lead to depreciation in value. For every 20,000 miles added to your total mileage, you can assume around 20% to be taken off your car‘s overall market value as buyers perceive these vehicles as having more wear-and-tear. This rate of depreciation can be even higher for older vehicles with significant mileage.

A complete service history can help offset the impact of higher mileage. It reassures buyers that your car has been properly cared for, making overall condition just as important as the number on the odometer.

Lower mileage vehicles may also still be under manufacturer warranty, which provides added peace of mind for buyers. For vintage or classic cars, however, high mileage may not necessarily mean lower value. Given their historical significance, these vehicles are often valued because of their age and condition, not in spite of it.

Is high mileage always bad?

High mileage isn’t the end of the world. It’s just one aspect of your car’s valuation. A well-maintained car with higher mileage can actually retain more value than a neglected car with fewer miles on the clock.

What does “well-maintained” look like? A documented service history, regular oil changes, timely component replacements, and generally keeping your car looking its best all make a difference. A three-year-old car that’s been well maintained but well used can still attract strong offers from dealers.

Does mileage vary by car type?

Yes, vehicle type and average annual mileage go hand in hand.

SUVs are typically designed to endure significant mileage and used by drivers for this purpose, so they usually exceed the UK national mileage average. In comparison, luxury vehicles boast the lowest annual numbers of miles driven per car type and often require more frequent maintenance. For electric cars, mileage is closely connected to EV battery charge and lifespan. In terms of fuel type, diesel cars tend to attract drivers who frequently hit the road for longer distances and therefore tend to have higher mileage. However, this has to do with buying habits rather than vehicle dependability (these are rough estimates and can vary by individual usage):

FAQs

At what mileage does a car die?

There’s no single mileage where a car simply stops working. A well-cared-for car can last more than a decade, so you shouldn’t expect to send your car to the scrap heap at less than 100,000 miles with proper maintenance.

Here’s a rough guide to what to expect at different milestones:

50,000 to 100,000 miles — Major components such as timing belts and water pumps may need replacing.
Beyond 100,000 miles — Wear on critical engine and transmission parts increases, meaning more frequent repairs.
Up to 300,000 miles — Possible with significant investment in repairs and replacements, but at that point, it’s worth considering whether the cost outweighs simply selling your car and finding another one.

Can you sell a car with mileage discrepancy?

A mileage discrepancy means the recorded mileage on a car doesn’t match what’s shown in its history — for example, if the odometer reads lower than a previous MOT record suggests. Knowingly selling a car with a false mileage reading is illegal.

If you notice a discrepancy, don’t try to hide it. Disclose it upfront to any potential buyer. Your car’s mileage is recorded at every MOT test, so buyers and dealers can cross-check it easily. Keeping your full MOT history on hand helps you stay transparent and avoid disputes when you sell.

If you’re unsure whether your car’s mileage history is consistent, an HPI check or full vehicle history report can confirm what’s on record before you list it.

Should I worry about car mileage?

Mileage matters, but it’s one factor among many. Dealers and buyers also weigh your car’s condition, service history, age, colour, and spec. A high-mileage car with a full service history and no cosmetic damage can still attract strong offers. A low-mileage car that’s been neglected may be worth less than you’d expect.

Rather than trying to limit your driving to protect your car’s value, focus on keeping it well maintained and holding onto your service records. That’s what makes the biggest difference when it’s time to sell.

How much does mileage reduce car value?

As a general rule, every 20,000 miles added to your car’s odometer reduces its value by around 20%. That works out at roughly 1% per 1,000 miles, though the exact figure varies by make, model, age, and condition.

Older cars with high mileage tend to depreciate faster than newer ones. Mileage that falls within the average range for a car’s age — around 10,000 miles per year — will usually have less impact on price than mileage that’s significantly above average.

If your car has higher mileage, a strong service history can help offset some of that depreciation in the eyes of buyers and dealers.

Is high mileage on a young car a problem?

It depends on context. In the UK, the average car covers around 7,500 to 8,000 miles a year. So a two-year-old car with 50,000 miles on the clock is well above average and is likely to attract lower offers than a comparable car with 15,000 to 20,000 miles.

That said, it’s not automatically a dealbreaker. If the car has been well maintained — with full service records and no cosmetic or mechanical issues — buyers and dealers will take that into account. High mileage on a young car tends to have the most impact on value when service history is incomplete or the car shows clear signs of heavy use.

Use the age-to-mileage table above to see how your car compares to the average, then check your car’s current value to get a clearer picture before you sell.

How can you track your car’s value?

If you’re not sure what your car’s value is to begin with, it’s hard to know how much money mileage might take off the price.

All vehicles depreciate at varying rates, with no rule of averages accurately describing any one car’s changing value. Motorway’s Car Value Tracker provides a free, reliable monthly price alert for up to six vehicles at once.

Follow changes to your car’s value to choose the best time to sell, and make informed choices about investments in your car’s maintenance.
