# Periodic loan

A periodic loan is the main loan type used by InfinityPools. It is a combination of the two previous types of loan (fixed term and revolving). Periodic loans start off as fixed term loans and switch to revolving loans after a predetermined "lock in" period. In the implementation of the protocol, a periodic loan with a lock in of 0 is a revolving loan and one of infinity is a fixed term loan.
