Housing does most of the damage
Almost the entire gap between two cities is shelter. Tradable goods cost roughly the same everywhere; land does not. A one-bedroom runs about $950 a month in St. Louis and $1,600 in St. Petersburg — $650 a month apart, or $7,800 a year.
Buying sharpens the same story. Median home prices sit near $240,000 in St. Louis against $390,000 in St. Petersburg — at 20% down, about $30,000 apart in cash up front, before property tax rates in Missouri and Florida enter the picture.
Taxes the index leaves out
Florida levies no state income tax; Missouri does. On $100,000 that is commonly $4,000–$8,000 a year of take-home, enough to offset a real gap in rent. Cost-of-living indexes exclude income tax, so comparing them alone misleads here.
The offset is rarely free, though. States without an income tax usually recover it elsewhere — property tax rates in Florida and sales tax are the usual places to look. If you plan to buy rather than rent, run the property tax number before assuming the no-income-tax state is cheaper.
There is a city-level tax to account for as well: St. Louis charges about 1.00% local income tax, while St. Petersburg charges none. On $100,000 that is roughly $1,000 a year, deducted before you ever see it and easy to miss when comparing two offers.
Getting around
St. Louis is served by limited transit; St. Petersburg is effectively car-dependent.
Work, weather, and what else is different
St. Louis is a large metro of about 2.8M and roughly flat; St. Petersburg is a large metro of about 3.2M and growing steadily.
Both metros have real employment in healthcare, which matters if you want to move without changing careers — your experience is legible to employers in both. St. Louis also leans on financial services and biotech, with employers like BJC HealthCare and Boeing. St. Petersburg leans on tourism and finance/insurance, with Raymond James Financial and Johns Hopkins All Children's Hospital.
The part spreadsheets leave out. St. Louis: Continental climate with cold winters near 22°F lows and hot humid summers with July highs near 90°F. St. Petersburg: Subtropical climate with mild winters near 55°F lows and hot humid summers with July highs near 91°F; part of the Tampa Bay hurricane-exposed metro.
City of St. Louis levies a 1% earnings tax on residents and on nonresidents who work in the city, on top of Missouri state income tax. No Florida state income tax, but property and flood insurance costs are high and rising due to hurricane and storm-surge exposure along Tampa Bay.
