Depreciated Cost

Updated October 1, 2019

What is Depreciated Cost?

Depreciated cost is the cost of an asset minus its accumulated depreciation. Another term for this concept is net book value.

The formula for depreciated cost is:

Depreciated Cost = Original Asset Price - Accumulated Depreciation

How Does Depreciated Cost Work?

Let's assume Company XYZ purchased 10 trucks at the same time five years ago for a total cost of $250,000. The trucks have a 10-year useful life, so the fleet depreciates each year by $25,000 per year ($250,000 / 10). Because five years have gone by, the depreciated cost of the fleet is now:

$250,000 original cost - ($25,000 annual depreciation x 5 years) = $125,000

The depreciated cost, or net book value, of the truck fleet is $125,000.

Why Does Depreciated Cost Matter?

Although depreciated cost is most simply stated as asset cost minus accumulated depreciation, it is by no means a precise measure of value. Accounting methods can assume that assets have a current value that may be unrealistic in the marketplace. For example, a company that owns commercial real estate with a resale value of $1 million may have fully depreciated the asset on the balance sheets to indicate a net value of zero. In this example the book value of the asset -- and perhaps of the organization as a whole -- would therefore be understated.
