A more thorough explanation:

A one-time charge is a fee that is assessed only once, rather than on a recurring basis. It is also known as a special charge or exceptional charge. This type of charge is typically excluded from income calculations as it is considered an ordinary cost of business.

Examples of one-time charges include:

• Delinquency charge: A fee assessed against a borrower for failing to make a payment on time.
• Late charge: An additional fee assessed on a debt when a payment is not received by the due date.
• Noncash charge: A cost, such as depreciation or amortization, that does not involve an outlay of cash.

These examples illustrate how a one-time charge is a fee that is only assessed once, rather than on a recurring basis. They are typically associated with specific events, such as a missed payment or the depreciation of an asset.
