What a Car Really Costs: Beyond the Sticker Price
The price on the windscreen is the one cost of a car you will never pay again. The expensive part is everything that happens after you drive off, and most of it is invisible at the dealership.

People shop for cars on two numbers: the sticker price and the monthly payment. Both are misleading. The sticker is a starting point for negotiation, and the monthly payment can be made to look small by simply stretching the loan. The number that actually matters is total cost of ownership: everything the car takes from you across the years you own it, divided by how long you keep it.
Depreciation is the biggest cost, and it is silent
The largest expense of owning most cars is not fuel, insurance, or repairs. It is depreciation, the value the car loses while you own it, and you never see a bill for it. A typical new car loses around 20% of its value in the first year and roughly 60% over five years. On a £30,000 car, that is about £18,000 gone, whether you drive it or not.
| Cost | Typical share of TCO | Visible? |
|---|---|---|
| Depreciation | 40 to 50% | No, until you sell |
| Fuel or charging | 15 to 25% | Yes, at the pump |
| Insurance | 10 to 15% | Yes, annually |
| Maintenance and repairs | 10 to 15% | Yes, painfully |
| Tax, fees, financing interest | 5 to 15% | Partly |
The costs people obsess over, fuel and repairs, are the visible ones, and they are rarely the biggest. The invisible one dominates, which is why the single most effective way to spend less on cars is to buy ones that depreciate slowly and keep them a long time.
Why buying nearly new is usually cheaper
Because the steepest depreciation happens in year one, letting someone else absorb that first-year drop is the biggest saving available in motoring. A one-to-three-year-old car has already shed its worst depreciation, has most of its life left, and often still carries warranty. You pay for the metal, not for the privilege of being first.
annual cost = (purchase price - resale value) / years + running costs per year
The first term is depreciation; running costs are fuel, insurance, maintenance, tax, and interest.
The one comparison that matters
When choosing between two cars, do not compare sticker prices or monthly payments. Estimate what each will actually cost you per year of ownership: expected depreciation plus running costs. A cheaper car that depreciates fast and drinks fuel can easily cost more per year than a pricier one that holds its value and sips. That per-year number is the honest basis for a decision.
- Estimate resale value at the point you plan to sell, not just the purchase price.
- Add up annual running costs: fuel, insurance, servicing, tax.
- Include loan interest if financing; it is a real cost of ownership.
- Divide the total by the years you will keep it for a true annual figure.
- Compare cars on that annual figure, not on the sticker or the monthly payment.
Frequently asked questions
What is the biggest cost of owning a car?
Depreciation, for most cars. It typically accounts for 40 to 50 percent of total ownership cost and is invisible because you only pay it when you sell. Fuel and repairs, the costs people watch, are usually smaller.
Is it cheaper to buy new or used?
Nearly new is usually cheapest per year. A new car loses around 20 percent in year one; buying a one-to-three-year-old car lets someone else absorb that drop while leaving most of the car's life, and often some warranty, for you.
Why is a low monthly payment misleading?
Because it is usually achieved by stretching the loan over more years, which increases total interest and keeps you owing more than the car is worth for longer. Total cost of ownership, not the monthly payment, is the number to compare.
