Compare / Des Moines to St. Louis
Des Moines, IA vs St. Louis, MO
Simple answer
You'd likely save $11 a month in St. Louis.
This is the HUD 2-bedroom fair-market rent for October 2026 through September 2027. It is not your lease.
The largest cost gap in this pair is housing prices. The BEA housing price parity differs by 5.7 points (Des Moines 84.7, St. Louis 79.0).
Iowa taxes wages at a flat 3.80%. Missouri taxes wages at rates up to 4.70%. Combined sales tax differs by 1.5 percentage points, higher in Missouri. The effective property tax gap is 0.50 percentage points, higher in Iowa.
After a move from Iowa to Missouri, those two example households keep the same benefit status labels. A different income can still split Medicaid and marketplace credits.
A $75,000 salary in Des Moines lines up with about $77,770 in St. Louis on the 2024 all-items price parity. Census median gross rent and the commute figures are 2024. Fair Market Rents are fiscal year 2027.
