-$500/mo
less than Illinois each month, renting
Worth knowing
The move pays for itself in about 4 months
Moving costs somewhere around $1,714, and Missouri runs about $500 a month cheaper. After roughly 4 months you are ahead.

What the move itself costs
$1,400 to $3,400
From a container you load yourself up to full-service movers.
Shipping one car adds about $350 to $600, against roughly $50 in fuel and lodging to drive it the 1-day trip yourself.
These are statewide figures. Chicago is not Illinois-average and St. Louis is not Missouri-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.
