Cost of Living by State: 2026 Rankings, Cost Breakdown & What It Means for Homeowners

From January through August 2026, the Pearl research team analyzed data from five independent sources, the Council for Community & Economic Research's Cost of Living Index¹, the U.S. Bureau of Labor Statistics' Consumer Expenditure Survey², U.S. Energy Information Administration electricity price data³, LendingTree's Cost of Raising a Child report⁴, and WalletHub's Tax Burden by State analysis⁵, to determine how living costs vary across all 50 states and the District of Columbia. The study covers five cost categories: overall composite cost of living, category-level breakdowns within that index, electricity price, childcare cost, and state tax burden, cross-referenced against the U.S. Bureau of Economic Analysis's Regional Price Parities⁶ for validation.

Table 1. The 2026 Cost of Living Index, State by State¹

Key Takeaways:

• Oklahoma holds the lowest composite index at 83.0, while Hawaii holds the highest at 185.8, a gap of more than 100 points and more than double.¹
• Every state in the ten least expensive positions sits in the South or Midwest, while every state in the ten most expensive positions sits on the East or West Coast or in the Northeast.¹
• Housing drives most of the spread, ranging from 65.1 in Oklahoma to 302.6 in Hawaii, a 4.6 times difference, while grocery costs stay far more compressed, ranging only from 94.1 to 135.8.¹
• The composite index does not predict every category. Minnesota's overall index of 93.4 places it in the lower half nationally, but its health category index of 114.4 runs above several states with a higher composite score.¹

What Drives the Difference? Category Breakdown

A reader who sees Hawaii ranked as the most expensive state naturally wants to know which specific costs drive that ranking. Table 1 above already contains the answer, broken into six categories: grocery, housing, utilities, transportation, health, and miscellaneous goods and services. Reading across those columns rather than down the index column isolates the cause of each state's ranking.

• Housing is the dominant driver of state-to-state cost differences, ranging from 65.1 in Oklahoma to 302.6 in Hawaii, a 4.6 times spread larger than any other category.¹
• Grocery costs are the most compressed category nationally, ranging only from about 94 to 136 across all 51 rows.¹
• Connecticut, Maine, and Rhode Island each run well above their overall composite index on utilities specifically, a pattern the composite index alone conceals.¹
• Minnesota's health category index of 114.4 sits well above several states with a higher overall composite score, another category-specific pattern invisible in the composite ranking.¹

Salary Equivalency: What You Would Need to Earn to Relocate

A reader comparing two specific states naturally wants to know what the index difference means for their own paycheck. Table 2 below converts the composite index into a salary comparison: divide the destination state's index by the origin state's index, then multiply by the current salary. The table illustrates the formula using a round $100,000 baseline.

Table 2. Salary Equivalency Between Selected States¹

Key Takeaways:

• Moving from a high-cost coastal state to a low-cost Southern or Midwestern state typically reduces the salary needed to maintain an equivalent lifestyle by 40 to 55 percent.¹
• The relationship grows more extreme at the high end of the index range: an Oklahoma household earning $100,000 would need more than $220,000 in Hawaii to maintain the same standard of living.¹
• This table is a planning illustration based on the state-level average index and does not account for an individual household's specific spending mix.

Electricity Costs by State: A Hidden Driver of Ongoing Cost of Living

Housing and groceries dominate most cost of living comparisons, but electricity is a recurring cost that the composite index does not isolate on its own. Table 3 below ranks all 51 jurisdictions by average residential electricity price.

Table 3. Average Residential Electricity Price by State, 2026³

US average: 18.56 cents per kilowatt-hour.

Key Takeaways:

• Hawaii's electricity rate of 42.23 cents per kilowatt-hour is more than 3.5 times North Dakota's rate of 11.95 cents, a wider relative spread than the composite cost of living index shows.³
• A state's electricity ranking does not always track its overall cost of living ranking. Michigan and Pennsylvania sit near the middle of the composite index but rank among the 15 most expensive states for electricity specifically.^1,3
  

The Cost of Raising a Child by State

Childcare and child-related costs are absent from every general cost of living index examined in this study. Table 4 below reports the 18-year total cost of raising a child, net of dependent tax benefits, for a two-earner household.

Table 4. Cost of Raising a Child to Age 18, by State⁴

National average: $303,418 over 18 years, about $16,857 per year.⁴

Key Takeaways:

• Hawaii's cost of raising a child, $412,661, is more than double New Hampshire's cost of $201,963, a wider gap than the composite cost of living index shows between the same two states.⁴
• Kansas ranks sixth most expensive for child-rearing costs but sits near the middle of the composite index, showing this ranking does not track the primary table closely.^1,4
• DC, which offers free preschool for 3- and 4-year-olds, ranks 50th of 51 for child-rearing costs, among the least expensive, despite ranking 48th, near the most expensive, on the composite index.^1,4

State Tax Burden: The Category That Can Flip the Ranking

Taxes are the final major cost category absent from the composite index. Table 5 below reports total tax burden, combining property, individual income, and sales and excise taxes, as a share of personal income. This dataset covers 50 states; the source analysis does not include the District of Columbia.

Table 5. State and Local Tax Burden, 2026⁵

Key Takeaways:

• Seven states charge no individual income tax: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, and Wyoming.⁵
• Hawaii carries both the highest composite cost of living index and the highest total tax burden at 13.30 percent, meaning taxes compound the state's cost rather than offsetting it.^1,5
• Texas and Tennessee combine a low cost of living ranking with a low tax burden, while New York and New Jersey combine a high cost of living ranking with a high tax burden. Tax burden does not consistently correlate with overall cost of living ranking.^1,5
