A $70,000 salary stretches much further in Oklahoma than in Hawaii or California. See how state-level cost differences can add or subtract thousands from your real spending power
Where you live in the U.S. can dramatically alter what your paycheck actually buys. While a six-figure income may sound comfortable, the reality is that the cost of living varies so widely between states that the same salary can mean very different lifestyles depending on your ZIP code. According to the Missouri Economic Research and Information Center (MERIC), these differences are now at their widest in years, with some states offering far more purchasing power than others.
States Where Dollars Go Further
Oklahoma currently leads the nation in affordability, with a MERIC composite cost of living index of 84.7-about 15% below the U.S. average baseline of 100. This means that everyday expenses, from groceries to healthcare, are generally lower than in most other states. Housing is a major driver: Oklahoma's housing subindex is just 68.8, and the median home value stands at $222,100, based on 2024 Census data. That translates to a much lower down payment and monthly mortgage compared to high-cost states.
Other states with low overall costs include Mississippi, West Virginia, Alabama, and Kansas, all clustered in the South and Midwest. These regions consistently offer below-average prices for essentials, making them attractive for households looking to maximize their income. The migration data reflects this trend: nearly 15 million Americans moved last year, with many seeking out states where their money goes further.
Where Living Costs Climb
At the other end of the spectrum, Hawaii stands out as the most expensive state, with a MERIC index of 183.9-meaning costs are 84% above the national average. Housing is especially steep: the median home price is $875,900, nearly four times higher than in Oklahoma, and the housing subindex is a staggering 299.0. Renters also face high costs, with median monthly rent at $1,942, the second highest in the country.
Massachusetts, California, the District of Columbia, and New York round out the top five most expensive places to live. California's housing subindex is 199.4, and its median gross rent is the highest in the nation at $2,104. These high costs have contributed to significant outbound migration, with California leading the nation in residents moving out in 2025, according to North American Van Lines. In these states, even high incomes can be offset by the elevated cost of essentials, especially housing.
Income vs. Affordability
Comparing median household income to the cost of living index reveals how much purchasing power varies. For example, Oklahoma's median household income of $66,148, when adjusted for its low cost of living, is equivalent to about $78,100 in national terms. In contrast, Massachusetts boasts a much higher median income of $104,828, but after adjusting for its higher costs, that income is worth only about $70,600. This gap highlights why a high salary in an expensive state may not go as far as a more modest income in a cheaper state.
New Jersey offers a unique case: while it ranks among the most expensive states with a composite index of 115.3, its median household income of $104,294 is the second highest in the country. This higher income helps offset the elevated costs, but the trade-off between income and expenses remains a key factor for residents considering relocation.
Housing's Outsized Impact
Housing costs are the single largest factor in state-by-state affordability. In Oklahoma, a 10% down payment on a median-priced home is about $22,000, compared to $88,000 in Hawaii. Even within affordable states, rising demand can push prices higher, as seen in Tennessee, where the median home value has climbed to $332,600 despite a relatively low overall cost of living index. For renters, monthly costs can also vary widely, with some states offering rents less than half those in the most expensive markets.
According to the U.S. Census Bureau's 2024 American Community Survey, the national median home value was $354,600, and the median gross rent was $1,268. These figures provide a benchmark for comparing state-level affordability and highlight the significant disparities that shape household budgets across the country.
Migration and Financial Choices
The widening gap in cost of living is influencing migration patterns, as Americans weigh the trade-offs between income, expenses, and quality of life. States with lower costs are attracting new residents, while high-cost states are seeing more people leave. For many households, the decision to move is driven less by salary and more by what that salary can actually buy after accounting for housing, taxes, and everyday expenses.
Ultimately, understanding the real value of your income requires looking beyond the paycheck to the full picture of local costs. As state-level differences continue to grow, the financial stakes of where you live have never been higher.
Cost of living indexes, such as those published by MERIC, use a national average of 100 as a baseline. States below 100 are less expensive than average, while those above are more costly. These indexes combine data on housing, groceries, utilities, transportation, and healthcare to provide a comprehensive view of affordability. For households considering a move, comparing both income and cost of living can help clarify the true impact on their finances.
