Prime Rate - Definition

The interest rate a bank charges its best or "prime" customers. Each bank will quote a prime lending rate. Many institutions quote prime rates established by large money center commercial banks. There is also a prime rate average listed in the Wall Street Journal that is an average of the largest commercial banks. The rate given to consumers on their loans is often based as the prime rate plus a certain percentage, which represents the lender's assessment of the risk in lending, plus its profit margin.
