Overdraft credit refers to the amount of money a bank allows a customer to overdraw from their account. This type of credit is often used to cover unexpected expenses or to bridge the gap until payday. However, there are several synonyms for the term 'overdraft credit' which can be used interchangeably in financial jargon. These include lines of credit, credit lines, revolving credit, and open-end credit. Regardless of the term used, the concept remains consistent - a credit line that can be drawn upon when needed, subject to certain terms and conditions. Financial institutions typically charge interest on any amount overdrawn, and may also levy additional fees.
