Just looked into which states will absolutely drain your wallet and it's wild how much the gap is. Hawaii is in a league of its own - annual living costs hit $132k, which is almost $60k above the national average. Honestly didn't expect it to be that extreme. Massachusetts and California are also brutal at around $104k and $102k respectively, but Hawaii just dominates. The thing is, it's not just one category making these places expensive. In Hawaii it's everything combined. Massachusetts gets hit hard on utilities - nearly $18k a year versus the national average of like $14.5k. California's transportation costs are insane because of gas prices and basically no public transit infrastructure. Looking at the data, the highest cost of living by state really comes down to housing, healthcare, and utilities being stacked against you. Alaska's interesting because healthcare there is 52% above average - limited medical providers drive prices up. Meanwhile states like Rhode Island and Connecticut are pricey but not quite at the extreme level. If you're thinking about relocating, it's worth checking what specific costs hit hardest in each state. The highest cost of living by state varies a lot depending on what category drains you most.
