The hidden cost of car depreciation
The largest cost of most cars isn't fuel or insurance — it's the value quietly lost every year. Here's how depreciation works and how to blunt it.
What the sticker leaves out
Depreciation is the value a car sheds over time; you only feel it the day you sell or trade in, which is why it's so easy to ignore while you own it.
New cars typically lose the largest share of their value in the first year and the early years, so buying nearly-new can hand that steep initial drop to someone else.
How well a car holds value varies widely by model, fuel type, colour and desirability — two cars bought for the same price can be worth very different amounts a few years later.
Higher mileage, wear, a patchy service history or accident damage all reduce resale value beyond ordinary age-related loss.
Options that were pricey new rarely return their cost at resale, and shifts in demand (fuel prices, emissions rules) can move a whole category's values.
Over a typical ownership period depreciation often exceeds fuel, tax and servicing combined — so it deserves the most attention, not the least.
Why the purchase price misleads
The price you pay says nothing about what the car will be worth when you're done with it — and that gap is the real cost. A cheaper car that loses value fast can cost more to own than a dearer one that holds it, because depreciation is usually the biggest line of all and it's invisible until you sell. Judging a car by its sticker instead of its whole-life cost is exactly the mistake that makes depreciation so expensive.
How to work out your true cost
Estimate depreciation as the price you pay minus a realistic resale value for the year you plan to sell, then add it to insurance, fuel, tax, servicing and tyres. Value-holding, in-demand models and buying nearly-new (letting someone else absorb the first-year drop) are the biggest levers. For a sourced, dated figure on a specific car, run it through the calculator rather than a rule of thumb.

If you buy through a partner link we may earn a referral fee at no extra cost to you, and it never changes which car we rank first or the figures we show. Placement can't be bought — the order is decided by the true total and verifiable quality, never by who pays us. See our affiliate disclosure and methodology.

Frequently asked
It's the value a car loses over time — the difference between what you pay and what it's worth when you sell. It's usually the single biggest cost of ownership, and because you only feel it at resale, it's the one most people overlook.
It varies by model, fuel type and demand rather than any fixed rule — some hold value far better than others. The reliable way to judge is to compare a specific car's likely resale value for the year you'd sell, not to assume.
Buy a model that holds value, consider nearly-new to skip the steep first-year drop, keep mileage sensible, and maintain a full service history and good condition. Each protects resale value, which is what depreciation really measures.
