What is the cheapest state to live in?

How ‘cheapest state to live in’ is measured and how it differs from most expensive cities in the united states

Definitions: price level, purchasing power, and living-wage budgets, most expensive cities in the united states

The phrase most expensive cities in the united states usually refers to city or metro lists that show high-cost pockets, while state measures average prices across all counties and metros to show typical purchasing power for residents. For standardized state comparisons economists rely on measures that adjust for price level differences, which reflect how far a dollar goes in a given state BEA Regional Price Parities (see the Tax Foundation purchasing-power map here).

State-level price measures are averages, so a state that looks cheap on average can still contain very expensive metro areas. Readers should keep this distinction in mind when they compare a headline like most expensive cities in the united states with state rankings that smooth those city extremes.

Why a state rank is not the same as city-level cost rankings

City lists measure local market extremes, while state indices average prices across urban, suburban and rural areas to produce a single state figure. That averaging changes how affordability appears at the household level and can mask metro variation in rents and housing supply.

Key data sources analysts use to rank states by cost

Government data: BEA RPPs and BLS consumer spending

BEA Regional Price Parities are the primary standardized price index analysts use to compare states because they measure broad price level differences across consumption categories and regions BEA Regional Price Parities. Related resources include a Federal Reserve Bank of San Francisco note on price disparities The Changing Disparity in Prices Across States and a FRED RPP series RPP series on FRED.

The BLS Consumer Expenditure Survey shows how households allocate spending across categories such as housing, transportation and food, which explains why some price changes matter more to budgets than others BLS Consumer Expenditure Survey.

Research and tools: MIT Living Wage, Zillow, and published rankings

Researchers and journalists use tools that translate price indices into example budgets and local housing measures; the MIT Living Wage Calculator provides living-wage baselines, Zillow offers housing and rent research, and outlets like WalletHub or U.S. News publish comparative rankings using their own weights Living Wage Calculator.

Each of these sources plays a different role: price indices standardize relative costs, expenditure surveys allocate budget shares, and living-wage or housing pages make those inputs actionable for specific household types.

Why housing and rent usually determine which states feel cheapest

How housing weights affect state price indexes

Housing and rent are the largest single drivers of cross-state cost differences, so analysts place heavy emphasis on local housing data when ranking cheapest states BEA Regional Price Parities.

Because rent and home prices can vary much more between metros than categories like groceries or utilities, a state with low average prices can still have pockets where housing makes day-to-day life expensive.

Recent housing trends that can change rankings quickly

Local housing-market shifts can move a state’s affordability ranking faster than slower-moving categories such as healthcare or some services, which is why housing research pages and recent sales or rent trends matter for up-to-date decisions Zillow Research.

For a practical check, compare statewide RPP adjustments with current metro rent indexes to see whether a statewide low price level reflects broad affordability or is driven by rural low-cost areas.

Translating price indexes into household budgets and living-wage estimates

How the MIT Living Wage Calculator converts data into monthly budgets

The MIT Living Wage Calculator converts price and wage inputs into example monthly budgets for different household configurations, making state-level differences easier to interpret for planning purposes Living Wage Calculator.

It is useful as a baseline because it applies local price adjustments to typical spending categories, producing figures you can compare across states or counties.

Using spending shares to model your own household costs

To model your household, start with BLS spending shares for your household type to allocate a baseline budget across housing, transport and food, then apply state RPP adjustments to each category to reflect local price levels BLS Consumer Expenditure Survey.

That approach helps you move from abstract price indexes to a practical monthly projection for your household size and work pattern, and it is most accurate when you replace statewide housing assumptions with county or metro rent data.

Comparing published rankings: why WalletHub, U.S. News and others disagree

Common methodological differences

Different outlets use different metric choices and weights, so a state that ranks low on one list may rank higher on another because one ranking emphasizes housing while another weighs taxes or wages more heavily WalletHub methodology.

How weights change the cheapest-state outcome

For example, lists that give greater weight to taxes and public services can move some mid-cost states toward the top of affordability rankings, while housing-focused lists favor states with low rent and home prices U.S. News rankings.

Before acting on a published list check its methodology to see whether it aligns with the categories that matter most to your household, such as housing, childcare or healthcare.

Decision criteria: choosing the cheapest state for your household

Checklist: housing, taxes, healthcare, income opportunities, and local services

Start with a ranked checklist: 1) housing and rent, 2) job market and local wages, 3) state and local taxes, 4) healthcare costs and coverage, and 5) transportation and access to services; these items usually explain most differences in practical affordability BEA Regional Price Parities.

Use county or metro housing indicators rather than state averages to test whether a state’s low headline price level delivers affordable housing in areas where you would live and work.

How personal factors change the outcome

Your employment situation, household size, and whether you can work remotely change which state is cheapest for you, because income opportunities and benefit eligibility can offset nominal price differences.

Weigh short-term savings against long-term prospects like career growth and access to health coverage when you evaluate relocation options.

Common mistakes and pitfalls when chasing the cheapest state

Ignoring metro pockets and commuting costs

A common mistake is relying on a headline state rank without checking metro or county pockets where housing and commute times can make living more expensive than the state average suggests BEA Regional Price Parities.

Long commutes or moves to peripheral metros can increase transportation and childcare costs enough to erase housing savings, so include realistic travel time and transit costs in your projections.

Overlooking taxes, health coverage, and job prospects

Another error is overlooking how state tax structure and health coverage options affect take-home pay and net costs; a low nominal price level can be offset by higher local taxes or limited public services BLS Consumer Expenditure Survey.

Check state and local tax rules and plan for healthcare premiums and out-of-pocket costs as part of your affordability assessment.

Practical examples: three household scenarios and how to compare states

Single adult renter on a modest wage

A single renter should focus on metro rent trends and the living-wage baseline for a one-adult household, using the MIT Living Wage Calculator for a state-level starting point and county rent indexes for local reality Living Wage Calculator. (See the author about page: about.)

Key checks are expected monthly rent, transit or car costs, and whether local wages support the rent level without long hours or second jobs.

Two-earner family with children

A two-earner family must balance housing with childcare, taxes and healthcare, so check both state RPPs and detailed spending shares from BLS to estimate how much of income will go to essentials in different states BLS Consumer Expenditure Survey.

Also compare local childcare costs and availability, because high childcare fees can offset lower rent in some low-cost states.

Retiree on fixed income

Retirees should prioritize healthcare costs, property taxes and the stability of local services as much as rent or housing, and use state living-wage and price indices as a check against expected fixed income purchasing power Living Wage Calculator.

For retirees, small differences in healthcare or property tax rules can change which state is effectively cheapest for a given income stream.

Bottom line: next steps for readers who want to find the cheapest state for them

A short action plan

Three steps to test states: 1) compare BEA RPPs to see relative state price levels, 2) build a household budget with the MIT Living Wage Calculator or a similar baseline, and 3) check local housing-market indicators to replace statewide housing assumptions BEA Regional Price Parities.

Keep in mind intra-state variation and recent housing trends when you finalize a decision, because local rent spikes or job shifts can change affordability quickly Zillow Research.
