Cost of Living Index by State 2025

Cost of living refers to the amount needed to cover basic expenses, such as food, shelter, transportation, and healthcare. However, costs of living can vary significantly across regions. Cost of living indexes help a person better understand and quantify these differences. Cost of living indexes are used by employers when determining wages or government agencies when determining the need for interventions, such as annual adjustments to Social Security benefits. Individuals also use these metrics when considering relocating, especially for a job.

Cost of living indexes are calculated by first determining a baseline for comparison. When comparing costs across states, the average cost of living in the United States is used as the baseline set at 100. States are then measured against this baseline. For example, a state with a cost of living index of 200 is twice as expensive as the national average. Likewise, living in a state with an index of 50 will cost about half the national average.
