Loss definition

What is a Loss?

A loss is an excess of expenses over revenues, either for a single business transaction or in reference to the sum of all transactions for an accounting period. The presence of a loss for an accounting period is closely watched by investors and creditors, since it can signal a decline in the creditworthiness of a business. This is particularly the case when the loss is derived from just the operational activities of a business.

The concept can also refer to the loss in value of an asset. In this case, it is considered an unrealized loss if you have not yet sold the asset, and so cannot be claimed as a tax deduction. Conversely, if you have incurred the loss by selling the asset, then you can claim a tax deduction on the amount of the loss.

FAQs

How does a loss differ from an expense?

A loss differs from an expense in that an expense arises from normal, ongoing activities undertaken to generate revenue, while a loss results from incidental or peripheral events. Expenses are expected and recurring as part of operations, whereas losses are typically unplanned and not directly tied to core business activities. As a result, losses often signal abnormal events or value declines rather than routine cost consumption.
