What type of income source would a receipt from a loan represent in accounting?

A receipt from a loan is classified as non-operating income in accounting because it does not arise from the primary activities of the business. Non-operating income includes any revenue that is generated outside of the core business operations. For instance, businesses primarily earn income through sales of goods or services, and any inflow from loans is not derived from those activities but rather represents a financial transaction that increases the available cash without impacting the operational performance.

Capital income generally refers to income derived from investments or the sale of capital assets, whereas operating income pertains to income earned from primary business activities, such as sales. Revenue income is a broad term but often overlaps with operating income. Since a loan receipt does not fit into these categories—it is specifically funding received that must be repaid, thus highlighting why it is correctly classified as non-operating income.
