The Post Adjustment system was designed to equalize purchasing power of United Nations salaries for professionals and higher categories, taking into account the cost of living differences between the base city of the system (New York) and other duty stations. The system aims at ensuring that, no matter where United Nations common system staff work at some 180 locations worldwide, their take-home-pay has a purchasing power equivalent to that at the base of the system.

The purpose of the rental subsidy scheme is to facilitate the settlement of new staff members and to encourage mobility within the UN Common System. It subsidizes the rental costs of eligible staff members whose rental accommodations are of a reasonable standard but cost significantly more than the average for the duty station. There are two different types of rental subsidy: one for staff members serving in Europe and North America and another for staff members serving outside Europe and North America.
