Revolving credit (or a revolving line of credit) is a type of loan that gives you continuous access to funds, up to an approved limit. When you use a portion of your line of credit, it reduces the amount available to you. For example: If you are approved for $1,000 and you use $300, you have $700 remaining available to you. Most revolving loans allow you to make charges throughout the month, pay them off and then make more charges. The most common types are credit cards and home equity lines of credit.
