Depreciation guide

How car depreciation changes the decision

Depreciation is one of the largest hidden forces in car ownership because it reduces the value of the asset you keep.

What depreciation means

Depreciation is the drop in a vehicle's value over time. A car can be enjoyable and useful while still becoming worth less each year. That loss in value matters when comparing buying cash, financing, and leasing.

Compound annual value drop

The calculator uses a compound annual value drop. For example, if a car drops 15% per year, year two is based on the value after year one, not the original price. That creates a smoother estimate than simply subtracting the same dollar amount every year.

Cash purchases

With a cash purchase, depreciation shows up as the difference between what was paid upfront and what the vehicle may be worth later. There is no monthly loan payment, but the owned asset is usually worth less than the original cash paid.

Financing and equity

When financing, depreciation should be viewed alongside remaining loan balance. If the car value drops faster than the loan balance, the owner may have limited equity or negative equity for part of the loan.

Leasing

In a standard lease, the driver usually does not own the car at the end. Depreciation may affect the lease economics, but the calculator does not count leased vehicle value as an owned asset.
