Depreciation Is A Noncash Expense

Depreciation is a term we frequently hear about, but usually don't really understand. It is an essential component of accounting. 

A common definition is that depreciation is a noncash expense that reduces the value of an asset as a result of age, wear and tear through use, or becoming obsolete over time.

A majority of assets will lose their value through time and they need to be replaced once the end of their useful life is reached.

Long-term operating assets that are not held for sale in the course of business are called fixed assets. Fixed assets include buildings, machinery, office equipment, vehicles, computers and other equipment. It can also include items such as shelves and cabinets.

Depreciation refers to spreading out the cost of a fixed asset over the years of its useful life to a business, instead of charging the entire cost to expense in the year the asset was purchased. That way, each year that the equipment or asset is used bears a share of the total cost.

As an example, cars and trucks are typically depreciated over five years. The idea is to charge a fraction of the total cost to depreciation expense during each of the five years, rather than just the first year.

Depreciation applies only to fixed assets that you actually buy, not those you rent or lease. Depreciation is a real expense, but not necessarily a cash outlay expense in the year it's recorded. The cash outlay does actually occur when the fixed asset is acquired, but is recorded over a period of time.

Depreciation is different from other expenses. It is deducted from sales revenue to determine profit, but the depreciation expense recorded in a reporting period doesn't require any true cash outlay during that period.

Depreciation expense is that portion of the total cost of a business's fixed assets that is allocated to the period to record the cost of using the assets during period. The higher the total cost of a business's fixed assets, then the higher its depreciation expense.
