DEFINITION of 'Entrance Fee'. A term that can refer to any charge for admission. However, it is commonly used in reference to continuing-care retirement communities (CCRCs). Rather than purchase a unit in a CCRC, residents typically pay a high entrance fee and monthly payments. The entrance fee is paid in exchange for services provided at the CCRC, such as nursing care throughout the lifetime of the resident.
