Suppose you buy a piece of office equipment for $17,000. After 3 years you sell it for a scrap value of $3,000. The equipment is depreciated linearly over 3 years. The rate of depreciation of the piece of equipment is

Depreciation amount = Purchase Price - Scrape Value
Depreciation amount = $17,000            -      $3,000
Depreciation amount = $14,000

depreciation rate = $14,000/3 years
depreciation rate= $4667.67
