Each of these groups includes the costs that are associated with them. Insurance, vehicle maintenance, toll fees, vehicle licensing and registration, bus or taxi fares, and any other transportation-related costs are included in the transportation group; the housing group includes insurance, maintenance, utilities, rent or mortgage payments, child care, phone bills, or any other cost associated with having a place to live. It is important to understand how the cost of living is calculated, how to compare different ones, and what the index tells you so that you can decide how far you will be able to make your paychecks go.
How Cost of Living Is Calculated
The cost of living is an index, so your specific expenses might be higher or lower, depending on where you live. For example, your fuel expenses would be higher if you live in New York than they would if you live in Mississippi. Agencies calculate the cost of living by finding prices for a representative sample of goods and services that are necessary for maintaining an average lifestyle. They then take into account how much of a person’s budget would be consumed by the item in a year. For example, a gallon of milk might not cost much compared to a dress, but over a year, food would cost more than clothing. So the price for each item is weighted to account for its importance to a typical family’s budget. These expenditures are totaled and averaged, and indexes are created to help compare different locations. The Bureau of Economic Analysis (BEA) calls these indexes Regional Price Parities (RPPs). Each state and Metropolitan Statistical Area (MSA—a large, populated area) have different RPPs because of the living variables discussed. A more thorough example is the federal government’s official measurement of inflation, the Consumer Price Index. The U.S. Department of Labor measures the prices of approximately 80,000 goods and services from 23,000 retail and service businesses. It then weights the items according to where they were purchased, according to data from a large survey sample. The CPI excludes income taxes but includes sales taxes.
Cost-of-Living Comparison and Index
Measurement indexes are generally used as a baseline for comparisons. A cost-of-living index gives you the percentage of the difference between the cost of living in your current location and another area. In other words, your cost of living is the baseline for you. Comparing costs of living is useful if you are considering moving to another area for work or retirement, as costs will be different depending on the location. It’s particularly useful when traveling internationally to compare international locations because a comparison compensates for exchange rate differences. The cost of living in your area would be the index of the comparison. If you have to live for a time on your usual pay when traveling or moving, you might end up over budget if you’re in an area with a higher cost-of-living.
Cost-of-Living Estimates
Cost-of-living tools and reports tell you the costs for various categories, such as housing, food, and gas. Keep in mind these are estimates based on survey samples, so your particular cost of living may be significantly different. For example, the Consumer Price Index compares the cost of living between any time period or between major U.S. cities and regions. The U.S. Department of State also offers links to a variety of resources to help you determine the best place for you to live. The Economist Intelligence Unit (EIU) provides a cost-of-living survey that compares cities around the world. It takes into account the relative cost of most goods and services. The EIU also provides a Global Liveability Index to assist in your comparison.
Highest and Lowest Cost of Living Worldwide
There are more than a few reasons to understand the costs of living around the world—the index can be used to give perspective on the value of your money, help you decide where to retire; assist policymakers when creating or adjusting policies and legislation on labor and commerce; and can help multinational companies determine salaries. Mercer’s 2021 Cost of Living City Ranking provides information on the cost of living around the world. According to the site, these are the top 10 most expensive cities in the world. The most expensive city is listed first: The 10 least expensive cities in the world are often in unsafe, poverty-stricken, or war-torn areas. The lowest-cost city is listed first:
Cost-of-Living Adjustment and Increases
The cost-of-living adjustment (COLA) is the change made to make wages or benefits stay current with the cost of living. The government uses it for federal retirees and recipients of Social Security benefits. The Social Security Administration announced a 5.9% benefit increase in 2022, up significantly from 1.3% for 2021. Other applications for the costs of living include government workers’ benefits, union negotiations, and corporate contracts for valued employees. Private employers sometimes also use the cost of living when employees are asked to relocate to a different location.
