Average Cost of Owning a Car Per Month UK
The monthly cost of owning a car in the UK is usually much higher than the fuel you put in it. Insurance, tax, servicing, repairs, tyres and depreciation can all change the real number.
This guide breaks car ownership into monthly cost categories so you can see where the money goes and avoid underestimating the true cost of running a car.
The simple answer
Many UK drivers can easily spend several hundred pounds per month once fuel or charging, insurance, road tax, maintenance, tyres, repairs, parking and depreciation are included.
A cheap car with low mileage might be closer to the lower end. A newer car, financed car, high-mileage car, expensive-to-insure car or premium model can cost much more every month.
Calculate your monthly car ownership cost
Use the calculator to estimate your real monthly cost, including depreciation, fuel or charging, insurance, road tax, maintenance, repairs, parking and other ownership costs.
Purchase & depreciation

Real UK cost benchmarks, not just estimates
These figures come from named, current UK sources rather than a guess, covering the categories that can genuinely be averaged nationally.
Insurance
£560/year
ABI, average comprehensive premium, Q1 2026
Road tax (VED)
£200/year
GOV.UK, standard rate, petrol/diesel car registered after April 2017
Servicing
£305-£335/year
Which?, petrol cars, survey of 63,334 owners, 2025
MOT test
£54.85
GOV.UK, statutory maximum test fee for a car
Fuel
around £1,130/year
around 7,000 miles/year (DfT) at 45 MPG and £1.60/litre petrol
Sourced subtotal (insurance, road tax, servicing, MOT and fuel)
around £2,270/year, or about £189/month
What this leaves out: depreciation, tyres, repairs and parking are all real costs, but none of them can be honestly averaged across every UK driver — they depend heavily on the specific car, its age and where you park. Depreciation in particular is often the single largest cost on a newer or financed car. Use the calculator above with your own car’s numbers for a complete picture, not just the categories that have a genuine national average.
Typical monthly car ownership costs
The exact amount depends on the car, mileage, insurance profile, location and how long you keep it.
Usually one of the most visible monthly costs, especially for commuting.
Can vary massively depending on driver, postcode, car, mileage and payment method.
Often paid annually, but it should still be budgeted monthly.
Regular maintenance should be spread across the year, not treated as a surprise.
Older cars, large wheels and high mileage can make this much higher.
The hidden monthly loss in value, especially on newer or expensive cars.
Example monthly ownership scenarios
These examples show why “average cost” is only useful as a starting point.
Low-cost ownership
A small, reliable, older petrol car with modest mileage, low insurance and simple servicing.
Likely pressure points: repairs, tyres and MOT surprises.
Typical daily driver
A common hatchback or family car used for commuting, errands and weekend journeys.
Likely pressure points: fuel, insurance, servicing and depreciation.
Expensive ownership
A newer, premium, financed, high-insurance or high-mileage car with larger tyres and higher repair risk.
Likely pressure points: depreciation, insurance, tyres and repairs.
Why car ownership costs feel higher than expected
Most drivers notice fuel and insurance, but forget the slower costs.
Monthly cost by category
Break the cost down like this before deciding whether a car is affordable.
Depends on mileage, MPG, electricity cost or fuel price.
Use the real quote, not a guess or another driver’s cost.
Divide annual road tax by 12 for budgeting.
Include servicing, MOT, tyres and a repair buffer.
Purchase price minus resale value, divided over ownership months.
Include permits, workplace parking, breakdown cover and subscriptions.
Cheap car vs expensive car ownership
The purchase price is only one part of monthly ownership cost.
A cheaper car can be cheaper if
- insurance is low
- fuel economy is sensible
- tyres are affordable
- it has strong reliability
- repair risk is manageable
An expensive car can cost more because of
- higher depreciation
- larger tyres
- higher insurance
- complex repairs
- premium servicing costs
How to reduce monthly car ownership cost
The best saving depends on which category is hurting you most.
Is car ownership worth the monthly cost?
The answer depends on convenience, location and alternatives.
Owning a car may be worth it if
- public transport is poor
- you need flexibility
- you commute regularly
- you have family or caring responsibilities
- you live outside strong transport links
Alternatives may be cheaper if
- you live in a city
- parking is expensive
- you rarely drive
- public transport is direct
- you can walk, cycle or car share
