Pro rata salary is one in which an employee receives the salary he would receive if he worked on a full-time schedule, but receives it proportionately for the amount of time he actually works. For instance, if the salary of a full time employee is ₹40,000 per month, then your pro rata salary will be ₹20,000 per month if you work 50% of the time. It is prevalent in part-time and contract employment.
