"Annual Percentage Rate (APR)" - Mortgage Glossary Terms and Abbreviations
A measure of the cost of credit, expressed as a yearly rate. It includes interest as well as other charges. Because all lenders, by federal law, follow the same rules to ensure the accuracy of the annual percentage rate, it provides consumers with a good basis for comparing the cost of loans, including mortgage plans. APR is a higher rate than the simple interest of the mortgage.
