What the move itself costs

$2,300 to $5,200

From a container you load yourself up to full-service movers.

Shipping one car adds about $650 to $900, against roughly $250 in fuel and lodging to drive it the 2-day trip yourself.

These are statewide figures. Hartford is not Connecticut-average and Chicago is not Illinois-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.
