Cost of Living Index Calculator

Last updated July 2, 2026

The cost of living index expresses the relative cost of maintaining a given standard of living across different geographic locations, with one location set as the benchmark at 100. The Missouri Economic Research and Information Center (MERIC) produces a widely used quarterly composite index for U.S. states; the Council for Community and Economic Research (C2ER) ACCRA Cost of Living Index provides city-level data updated quarterly. In Q1 2026, Hawaii maintained the highest composite cost of living index among states, roughly 185 percent of the national average, while Mississippi maintained the lowest at approximately 83 percent. Translating a $100,000 salary in Chicago to its equivalent in Dallas requires applying the ratio of the two cities' indexes to the nominal salary figure.

The practical applications of the cost of living index are numerous: comparing job offers in different cities, evaluating whether remote work from a lower-cost location improves financial quality of life, deciding where to retire to maximize retirement income, and understanding why two households with identical incomes can have radically different financial experiences depending on where they live. Housing is typically the largest variable in any cost-of-living comparison, accounting for 35 to 50 percent of the index differential between high- and low-cost cities. The same income that provides a comfortable lifestyle in San Antonio, Texas can produce genuine financial stress in San Jose, California, where housing costs alone are three to four times higher for comparable accommodations.

Using a cost of living index to translate any salary or income figure between locations before comparing job offers, evaluating relocation, or planning where to retire. The index ratio converts a nominal salary into what it would need to be in another city to maintain the same purchasing power. That equivalent salary is the only meaningful basis for comparing compensation across geographies.
