How Car Depreciation Actually Works

Depreciation is not linear, and treating it as though it were is the most common mistake in vehicle budgeting. A car sheds the largest share of its value in the first twelve months, typically 15% to 27% depending on segment, then declines geometrically at a slower rate each year afterward. Because the decline compounds against a shrinking base, the dollar loss per year falls steadily even though the percentage rate stays roughly constant. Eventually the curve flattens against a residual floor, the point below which a running vehicle retains value simply because it is transportation.

Why Segment Matters More Than Brand

Pickup trucks are the strongest value holders in the market, losing about 15% in year one and 11% annually thereafter, because demand for used work vehicles is deep and relatively insensitive to model year. SUVs and crossovers follow. Luxury sedans and electric vehicles sit at the opposite end, both around a 26% first-year drop, though for different reasons. Luxury sedans depreciate because their new-car price includes substantial brand premium that evaporates on resale, and because maintenance costs frighten second owners. Electric vehicles depreciate because the technology improves quickly enough that a four-year-old battery and range figure look dated against current models.

The Adjustments That Follow the Curve

Once the curve produces a baseline, appraisers layer adjustments on top. Mileage is measured against an expected 12,000 miles per year and valued at roughly six cents per mile of deviation. Condition grade moves the number by up to six percent upward for excellent examples and nearly thirty percent downward for poor ones. A reported accident costs about 12% regardless of repair quality, each additional owner costs about 2%, and complete service records recover about 3%. Finally, the sale channel applies: a dealer trade-in lands roughly 15% below private-party value, and an instant cash offer about 10% below, in exchange for speed.

Using Depreciation to Time a Sale

Because annual depreciation falls while maintenance costs rise, total cost of ownership per year usually bottoms out somewhere between years four and eight for mainstream vehicles. Selling before that point means paying for the steepest part of the curve without collecting the cheap years that follow. Holding well past it means absorbing rising repair bills for a vehicle that has little value left to lose. Professional Mode lets you project a hold period forward and see the all-in cost per mile, combining further depreciation with your actual insurance and maintenance figures, which is the number that should drive the decision rather than the sticker value alone.
