What this comparison leaves out

  • Taxes. State income, sales and property taxes differ a lot between states and are not included.
  • Where you live inside the state. Statewide figures average cities and rural areas; the metro lists above show the spread.
  • Your own spending mix. The default uses an average household. Use the housing slider if housing is a bigger share of your budget.
  • Timing. BEA price levels and incomes are for 2024; gas prices are weekly.
