What the move itself costs
$1,500 to $3,600
From a container you load yourself up to full-service movers.
Shipping one car adds about $400 to $600, against roughly $50 in fuel and lodging to drive it the 1-day trip yourself.
These are statewide figures. Boise is not Idaho-average and Billings is not Montana-average, so a specific city can look nothing like its state. Compare metro areas instead to narrow it to 387 real places, including which side of a state line you would live on.
Run this with your own numbers
Estimates only, not advice. Housing and income figures come from the U.S. Census Bureau's American Community Survey (2024); price levels from the Bureau of Economic Analysis (2024); tax rates are for the 2026 tax year, compiled from state revenue departments and the Tax Foundation. Moving costs are modelled from published ranges rather than quoted. Every figure is a statewide median or average and will not match any particular household.
