Inflation is running at its highest level in three years, sharpening cost pressures for households and complicating hiring decisions for employers across the United States. CNBC's 2026 America's Top States for Business study shows housing, rent and insurance costs are driving the heaviest burdens in a group of 10 particularly expensive states.
Highlights
- California ranks as the most expensive U.S. state for cost of living in 2026 with a score of 4 out of 50 and a grade of F.
- New York posts the country's highest rents as a share of median income and an average Manhattan home price of $2.9 million in Q1 2026.
- Colorado's average insurance premiums nearly doubled since 2020, while Florida and other states see housing and insurance pressures erode affordability.
2026 cost ranking and methodology
As reported by CNBC, the 2026 ranking measures cost of living as one of 10 competitiveness categories in America's Top States for Business, using price data from the Council for Community and Economic Research, housing affordability for owners and renters, and the cost to insure a median-priced home based on the most recent available data.The study says cost of living accounts for 2% of each state's total score. California ranks as the most expensive state in the list with a cost of living score of 4 out of 50 and a Top States grade of F, while Colorado, Florida, Hawaii, Rhode Island, Oregon, Connecticut, Washington, New York and Illinois also land among the 10 costliest states.
California posts the highest monthly housing costs in the nation, with 40% of residents spending more than 30% of income on housing. New York stands out for the country's highest rents as a share of median income and an average Manhattan home price of $2.9 million in the first quarter, while Washington and Connecticut also show elevated prices for everyday goods, rent and healthcare.
Housing and insurance pressures reshape state costs
Housing is the common pressure point across the ranking. Illinois has nearly a third of residents spending more than 30% of monthly income on housing, Oregon has 32.7% of residents paying more than one-third of income for housing, and Rhode Island's average rent for a three-bedroom home absorbs nearly 30% of median income.In several states, insurance costs are adding to the squeeze. Florida's housing and insurance strains are eroding what was once a more favorable cost picture, and Colorado is feeling the worst of the national insurance crisis, with average premiums having almost doubled since 2020.
For businesses, higher living costs can make recruiting more difficult and lift wage expectations. That leaves expensive states balancing strong economic appeal against rising household expenses that can weigh on workforce availability and operating costs.

We noted that homes priced above £5 million are facing growing pressure as buyers delay purchases and sellers adjust expectations, signaling that even traditionally resilient segments are being tested.
