Cost-of-living

Template:Globalize/USA

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 Adjustment (COLA)

Employment contracts, pension benefits, and government entitlements (such as Social Security) can be tied to a cost-of-living index, typically to the Consumer Price Index (CPI). A Cost of Living Allowance (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 his salary indexed by a differential CPI between the new and old employment locations, leaving the non-discretionary part of the salary (e.g. mortage payments, insurance, car payments, ...) unmodified.

Annual escalation clauses in employment contracts can specify retroactive or future percentage increases in worker pay which are not tied to any index. These negotiated increases in pay are colloquially referred to as cost-of-living adjustments or cost-of-living increases because of their similarity to increases tied to externally-determined indexes. Cost of living allowance is equal to the nominal interest minus the real interest rate.

CPI is not a COLA

When cost of living adjustments, negotiated wage settlements and budgetary increases exceed CPI, media reports frequently compare the two without consideration of the pertinent tax code. However, CPI is based on the retail pricing of a basket of goods and services. Most purchases of that same basket require the use of after-tax dollars — dollars that were often subject to the highest marginal tax rate. Consequently, the COLA will necessarily have to exceed the CPI/inflation rate to maintain purchasing power.

The widely recognized problem known as bracket-creep can also occur in countries where the marginal tax brackets themselves are not indexed — COLA increases simply place more dollars into higher tax rate brackets. (Only under a flat-rate tax system would a percentage gain on gross income translate into a comparable inflation-offsetting gain at the after-tax level.)

Some salaries and pensions in the U.S. with a COLA (they vary by type) include:

Pensions in Canada with a COLA include:

Worldwide Cost of Living Survey

The Economist Intelligence Unit produces a bi-annual (twice yearly) worldwide cost of living survey that compares more than 400 individual prices across 160 products and services. They include food, drink, clothing, household supplies and personal care items, home rents, transport, utility bills, private schools, domestic help and recreational costs.

The survey itself is a purpose-built internet tool designed to calculate cost-of-living allowances and build compensation packages for expatriates and business travellers. The survey incorporates easy-to-understand comparative cost of living indices between cities. The survey allows for city to city comparisons, but for the purpose of this report all cities are compared to a base city of New York, which has an index set at 100. The survey has been carried out for more than 30 years.

The most recent survey was published in February 2013 containing data from December 2012 . Tokyo Became the most expensive city that year, while Zurich, the top city in the survey the previous year dropped down 5 places. Sydney and Melbourne both got up in the index from previous years, with Sydney becoming the 3rd most expensive city (from the 7th spot), and Melbourne becoming the 4th (from the 8th spot). Asia is home to more than 10 most expensive cities in the top 20 but also home to 6 cheapest cities of the cheapest ten.

Other uses of the term "cost-of-living allowance"

Stipends or extra pay provided to employees who are being temporarily relocated may also be called cost-of-living adjustments or cost-of-living allowances. Such adjustments are intended to offset changes in welfare due to geographic differences in the cost of living. Such adjustments might more accurately be described as a per diem allowance or tied to a specific item, as with housing allowances. Employees who are being permanently relocated are less likely to receive such allowances, but may receive a base salary adjustment to reflect local market conditions.

A cost-of-living allowance is frequently given to members of the U.S. military stationed at overseas bases if the area to which a service member is assigned has a higher cost of living than the average area in the United States. For example, service members stationed in Japan receive a cost of living allowance of between $300 and $700 per month (depending on pay grade, years of service, and number of dependents), in addition to their base pay. This additional pay is non-taxable.
