The true cost of owning a car

The purchase price is only part of what a car costs. The biggest hidden cost is usually depreciation, the value it loses while you own it, on top of fuel, insurance, maintenance and tax. This calculator adds them all up to show the real cost per month, per year, and over your whole ownership.

Worked example

A 30,000 car worth 15,000 after 5 years loses 15,000 to depreciation. Add 4,500 a year of running costs and the total is 37,500, about 625 a month.

Why it matters

Two cars with the same price can cost very differently to own. A cheaper car that holds its value and sips fuel can easily beat a pricier one that depreciates fast and drinks fuel. Compare the monthly figure, not just the sticker price.
