Credit line
A credit line is the amount of money that can be charged to a credit card account. The size of a credit line, and how much of it has been borrowed, have a large influence on consumer credit scores. Low credit utilization -- that is, a credit line on which little has been borrowed -- leads to a higher credit score. Credit line is also known as a credit limit.
