California renters are now paying more for housing than residents in any other U.S. state, with the median gross rent reaching $2,104 per month, according to a new Investopedia report. This figure underscores the significant financial strain on millions of Californians, who are dedicating an increasing portion of their income to cover housing costs.
The high cost of housing is a primary driver of California's overall cost of living, which is more than 43% higher than the national average, based on the report's composite index of 143.1. The state's housing subindex stands at 199.4, nearly double the national average. This disparity is attributed to decades of insufficient home construction to meet demand, leading to escalating prices for both renters and buyers.
The affordability challenges have also contributed to a significant outflow of residents. In 2025, California was identified as the top state for outbound migration, with housing expenses and the general cost of living cited as the main reasons for departure.
In contrast to California's situation, states in the South and Midwest offer greater affordability. Oklahoma ranked as the most affordable state with a composite index of 84.7, followed by Mississippi, West Virginia, Alabama, and Kansas. Oklahoma's housing subindex was 68.8, approximately 31% below the national average.
Among the most expensive states, Massachusetts ranked second to California, with a composite index of 148.5. Hawaii led the nation with an index of 183.9, largely driven by its housing subindex of 299.0. The median home value in Hawaii was reported at $875,900, and its median monthly rent was $1,942, the second highest nationally.
The report also highlighted that higher median incomes do not always translate to greater purchasing power when adjusted for the cost of living. For instance, Oklahoma's median household income of $66,148 offers roughly $78,100 in purchasing power due to lower living costs. Conversely, Massachusetts' higher median income of $104,828 decreases to approximately $70,600 after accounting for its elevated cost of living.
