Car depreciation explained: why your car loses value

For most UK households, depreciation is the largest running cost of owning a car, bigger than fuel, insurance, tax and servicing combined. It is also the cost almost nobody tracks. Here is what is really happening to your car's value, and what you can do about it.

What depreciation actually is

Depreciation is the difference between what you paid for a car and what you get when you sell it, expressed over time. As a simple illustration, a car bought for £25,000 and sold three years later for £15,000 has depreciated £10,000, or about £3,333 per year. That is real money leaving your household, even though you never write a monthly cheque for it.

The rough UK depreciation curve

Every car is different, and there is no official UK depreciation statistic. As general guidance from our editors (not an official figure), the pattern for a typical mainstream UK petrol or diesel looks like this, with each year's loss applied to the value at the start of that year:

• Year 1: 20 to 30 percent loss from the new price. The biggest single drop.
• Year 2: a further 10 to 15 percent.
• Year 3: a further 8 to 12 percent.
• Years 4 to 7: roughly 8 to 10 percent per year, compounding on a shrinking base.
• Years 8 onwards: the yearly loss usually slows further.

Compounded, those ranges mean a typical mainstream car has lost about half its value by year 5 (roughly 45 to 58 percent, depending on where in each range it sits). Using the middle of each range:

Premium brands often lose a larger share of their new price, but keep a higher absolute value on the used market.

What drives depreciation

Brand and model desirability

Some models are genuinely wanted by used buyers (Toyota Corolla, Honda Jazz, Porsche 911, Suzuki Jimny) and hold their value unusually well. Others are aggressively discounted when new, which sets a low used-market ceiling (some Korean large saloons, some premium diesel estates in the 2020s). If you are buying new and resale matters, this is the biggest lever.

Mileage

The Department for Transport's National Travel Survey puts average annual car mileage at roughly 7,000 miles in recent years. Cars well above the mileage expected for their age are worth less, and the penalty grows with the car's price. Low-mileage cars attract a premium, but extremely low mileage can actually hurt value: a seven-year-old car with only 12,000 miles raises questions about seized brakes, perished rubber seals and a battery that has been on a charger for longer than it was driving.

Condition and service history

A full, stamped service history makes a car noticeably easier to sell and supports a higher price than a car with no history. Fresh MOT, clean bodywork, and a tidy interior each lift the value a bit more. The inverse is also true: unrepaired damage, scratches, kerbed alloys and a scuffed interior collectively knock off more than the cost of fixing them.

Fuel type and emissions

Petrol hybrids are currently in strong demand. Pure petrols are stable. Older diesels have softened in areas with clean air zones, where non-compliant vehicles can be charged to enter. Early EVs with shorter ranges have generally depreciated faster as battery technology has improved, while newer, longer-range EVs tend to hold up better. Plug-in hybrids sit in the middle, strong on urban use, less appealing as tax rules tighten.

Colour and spec

Popular colours (white, black, silver, grey) are easier to sell and hold value fractionally better than unusual colours. High-spec trims with desirable options (panoramic roof, parking sensors, cruise control, leather) add real money to a used value; exotic options (neon green exterior, custom upholstery) rarely do.

How depreciation differs by type of car

Using the curve above, a typical mainstream car keeps roughly half to two-thirds of its new price at three years old. Where a car sits within or outside that band depends on its segment:

• City cars and popular small hatchbacks: cheap to buy and run, steady used demand, usually close to the middle of the band.
• Family SUVs: strong used demand, though heavily discounted new models drag residuals down.
• Premium executive and large luxury cars: tend to lose the largest share of their new price, because few used buyers want expensive options and running costs.
• Desirable sports cars: some hold their value exceptionally well when supply is limited.
• Electric cars: older, shorter-range EVs have depreciated faster; newer long-range models are holding up better.

How to slow depreciation on a car you already own

• Service on time, every time. The gap between a full and a partial history is worth more than the services cost.
• Stay on top of advisories. Fix them promptly so your MOT history stays clean.
• Keep mileage moderate. Running at the UK average is the sweet spot.
• Protect the bodywork. A quality cover if outdoors, alloy wheel insurance if parking on street, a dash cam against minor collisions you did not cause.
• Keep the interior immaculate. No smoking, use mats and seat covers if you have kids or dogs.
• Time the sale well. Demand for used cars is often stronger in spring and around the March and September plate changes. See our guide on the best time to sell for more detail.
• Sell privately if you have time. A private sale usually achieves more than an instant-buy offer; compare both before deciding.

How to buy a car that depreciates less

If resale matters when you buy:

• Buy used, at three years old. The first owner has absorbed the biggest hit.
• Pick a popular body colour and a mid-trim spec that has the options most buyers want.
• Stick to mainstream Japanese, German or Korean brands known for reliability and residuals.
• Avoid heavily discounted new cars: the discount is priced in to future residuals.
• For EVs, look for battery warranties that transfer to the next owner, and a real-world range that suits your driving.

Why moValue tracks depreciation over time

For every car we value, we also show you a 3-year depreciation forecast and a 6-month price-trend chart based on current market data. That way you can see not just what your car is worth today, but whether it is a good moment to sell or whether waiting a month or two might actually help.
