Cost of living

Cost of living is the cost of maintaining a certain standard of living. Changes in the cost of living over time are often operationalized in a cost-of-living index. Cost of living calculations are also used to compare the cost of maintaining a certain standard of living in different geographic areas. Differences in cost of living between locations can also be measured in terms of purchasing power parity rates. Cost of living is the cost of maintaining a certain standard of living.

Employment contracts and pension benefits can be tied to a cost-of-living index, typically to the consumer price index (CPI). A COLA adjusts salaries based on changes in a cost-of-living index. Salaries are typically adjusted annually. They may also be tied to a cost-of-living index that varies by geographic location if the employee moves. In this later case, the expatriate employee will likely see only the discretionary income part of their salary indexed by a differential CPI between the new and old employment locations, leaving the non-discretionary part of the salary (e.g., mortgage payments, insurance, car payments) unmodified.
