Ask someone what their car costs and they will usually tell you what they spend at the pump. That is typically less than half of it. Add everything up — the tax, the tyres, the slow bleed of depreciation — and the average British car costs about £3,580 a year, or £296 a month. Spread across a typical year’s mileage, that works out at roughly 47p for every mile driven.
That is an average, and averages hide a lot. A ten-year-old Yaris driven 4,000 miles a year costs a fraction of it. A three-year-old diesel SUV on finance, driven 15,000 miles, costs considerably more. The point of the table below is not to tell you your number — it is to show you which lines are worth attacking.

The cost almost nobody counts
Depreciation is the second-biggest line in that table and the only one that never appears on a bank statement. Your car quietly loses value whether you drive it or leave it on the drive. A £20,000 car worth £11,000 three years later has cost you £3,000 a year in depreciation alone — more than fuel, insurance and tax combined.
Two consequences follow, and they are the most useful things on this page:
- Buying a three- to five-year-old car instead of a new one hands the steepest part of the depreciation curve to somebody else. It is by far the largest single saving available to any motorist, and it is a one-off decision rather than a daily discipline.
- Keeping a car longer flattens the curve. Once a car is past roughly eight years old, annual depreciation in pounds becomes small. Repair bills rise, but rarely as fast as depreciation falls. That arithmetic is behind a national trend: the average car on British roads is now over ten years old, the oldest it has ever been.
Before you write off an ageing car because of a £700 bill, work out what a replacement would cost in depreciation over the same period. If the newer car sheds £2,000 a year in value, that £700 repair buys a lot of motoring. Repairs are usually cheaper than they feel, because they arrive as a single frightening number instead of a slow invisible drip.
Cost per mile: the number that changes decisions
Annual totals are useful for budgeting. Pence per mile is what changes behaviour, because it prices individual journeys. At the UK average of about 47p a mile, a 12-mile round trip to a retail park costs roughly £5.60 in car — before you have bought anything. A 250-mile trip to see family costs about £118 there and back, which reframes the “but the train is £70” conversation entirely.
Work out your own figure like this:
- Add up a year’s fixed costs: insurance, VED, MOT, breakdown cover, any finance interest, and your best estimate of depreciation.
- Add a year’s running costs: fuel, servicing, tyres, repairs, parking.
- Divide by your annual mileage — your two most recent MOT certificates give you this exactly.
Or let the cost calculator do it. It splits the answer into costs you would pay even if the car never moved and costs that depend on mileage — which is the split that tells you whether your problem is the car or the driving.
What the individual bills look like
| Bill | Typical UK figure | Notes |
|---|---|---|
| Vehicle tax (VED) | £200 a year standard rate | Cars registered on or after 1 April 2017. Add £440 a year for five years if the list price was over £40,000 (£50,000 for electric). Full explanation |
| MOT test | Up to £54.85 | The legal maximum for a car. Many garages charge less, and some include it with a service |
| Petrol | Around 160p a litre | Moves weekly. Supermarket forecourts are usually several pence cheaper than motorway services |
| Interim service | £120–£200 | Oil, filter and a safety check. The oil-and-filter part is a realistic DIY job |
| Full service | £200–£400 | Independent garages typically undercut main dealers substantially on out-of-warranty cars |
| Front brake pads, fitted | £120–£250 | Parts alone are often £30–£60 |
| Mid-range 16″ tyre | £70–£110 fitted | Budget tyres save £30 now and cost you in wet braking distance |
Where the savings actually are
Ranked by what they are worth against how hard they are:
- Shop your insurance at every renewal. Loyalty is punished. Twenty minutes on comparison sites, plus a direct quote from your current insurer’s new-customer line, routinely beats the renewal letter by three figures. Fifteen ways to cut the premium.
- Buy used rather than new — the depreciation point above.
- Drive fewer miles. At 47p a mile, cutting 2,000 miles a year saves close to £950 in total costs. Twelve realistic ways to do it.
- Do the simple servicing yourself. Oil, filters, wipers, bulbs and pads add up to a few hundred pounds a year in labour. Here is what is genuinely doable.
- Do not fail the MOT. A failure means a retest, a rushed repair at whatever price the garage names, and sometimes a car you cannot legally drive. The ten-minute pre-check.
- Ease off. Smooth driving, correct tyre pressures and taking the roof box off are worth 5–15% of your fuel bill, for free.
Common questions
Is it cheaper to run an older car or buy something newer and more efficient?
Usually the older car, by a wide margin. Improved fuel economy rarely recovers the depreciation on a newer vehicle. A newer car makes financial sense mainly when the old one needs repairs approaching its total value, when your mileage is very high, or when a tax or clean-air-zone charge applies to what you currently drive.
How much does insurance really vary between quotes?
Enough to be worth an hour of your time. Two or three comparison sites do not cover the same insurer panels, and a few large insurers do not appear on comparison sites at all. Renewal quotes are also negotiable — quoting the cheapest rival price frequently produces a matching offer.
Do fuel-saving gadgets work?
No. Magnets on fuel lines, “tuning” chips sold for £30 and additives promising 20% economy do not survive independent testing. Correct tyre pressures, a lighter right foot and removing the roof box do.
What is the cheapest way to spread the cost?
Paying insurance annually rather than monthly avoids interest that is often 20–30% APR. The same applies to vehicle tax: paying by monthly Direct Debit costs £210 a year rather than £200. If cash flow allows, annual payment is a straightforward saving.
