Put annually: $41,600 gross, and the low cost of living here is the only reason it works. Here's the full breakdown, per hour, per week, per month.
$20.00 an hour is $41,600 a year gross at 40 hours a week. After federal tax, Social Security and Medicare, and Missouri income tax you keep $34,588, which is $2,882 a month or $1,330 every two weeks. Against St. Louis prices running 4.9% below the national average, that spends like $36,370 would somewhere average.
$20.00 an hour is $41,600 a year, and St. Louis runs 4.9% under the national average on prices. That gap doesn't get talked about much and it's felt every month.
So let's run the whole thing.
Everything here assumes 40 hours a week for 52 weeks, which is 2,080 hours a year with no unpaid time off. If your hours get cut, or the schedule dips in a slow month, scale it down from here. Single filer, standard deduction, 2026 brackets.
| Line | Amount |
|---|---|
| Gross pay (2,080 hours) | $41,600 |
| Federal income tax | −$2,812 |
| Social Security and Medicare | −$3,182 |
| Missouri state income tax | −$1,018 |
| Take-home pay | $34,588 |
| Take-home a month | $2,882 |
| Take-home every two weeks | $1,330 |
| Take-home a week | $665 |
| Take-home an hour | $16.63 |
| Adjusted for St. Louis prices (4.9% below average) | $36,370 |
Tax takes $7,012 of that $41,600, or 17% of it. What's left is $34,588 a year, which is $2,882 a month, $1,330 every two weeks, or $665 a week.
Put another way, your $20.00 an hour is really $16.63 an hour once withholding is done. That's the number to use when you're deciding whether an extra shift is worth it.
That last row is the one nobody shows you. The federal government scores every metro against a national average of 100, and St. Louis scores 95.1. Living here hands you back roughly $1,800 a year of buying power you wouldn't have somewhere average.
State tax is the line people forget until the first check lands.
Missouri takes about $1,018 a year at this wage, an effective rate of 2.4% once brackets, deductions and exemptions have all been applied. On a weekly check that's roughly $20.
Federal tax and FICA come off the same money, which is why multiplying hours by your rate always overshoots what arrives.
A one-bedroom at St. Louis's fair market rent runs $995 a month, $1,218 for a two-bedroom. Against take-home of $2,882 a month, the one-bedroom eats 35% of it.
That's over the 30% line, which puts you in what housing researchers call cost-burdened. It leaves $1,887 a month for food, transport, insurance, and anything you might want to save.
The cheapness here is concentrated where it counts. Housing in St. Louis runs 21% below the national average, against goods at 0% above.
Housing is the biggest line in most budgets, so a discount there is worth more than the headline figure suggests. This is the kind of place where a middling salary buys space.
Utilities are a genuine bright spot, running 30% below the national average.
St. Louis has bounced between 91 and 97 over 2008 to 2024 without settling into a direction.
Which is a reminder that this index moves. A figure quoted confidently from any single year, including this one, is a snapshot rather than a trend.
For what it's worth, St. Louis has not been more expensive than the national average in a single year of this series.
Turn it around and it runs in your favour. Matching what $20.00 an hour buys nationally only takes $19.02 an hour in St. Louis.
And here's the rent version of the same sum. A one-bedroom at $995 a month sits at 30% of take-home only once you're earning about $23.31 an hour, which is $3.31 an hour more than you're on. Full time, that gap is $6,890 a year.
| Metro | Price level100 = US avg | Take-home a month | Real value a year |
|---|---|---|---|
| St. Louis, MO | 95.1 | $2,882 | $36,370 |
| Oklahoma City, OK | 90.4 | $2,857 | $37,919 |
| San Antonio, TX | 94.7 | $2,967 | $37,598 |
| Atlanta, GA | 100.1 | $2,857 | $34,244 |

Compare my citiesIt's tight. $20.00 an hour in St. Louis holds $36,370 of real purchasing power once tax and local prices have both taken their turn, so roughly $5,200 a year is gone before you buy anything.
Nearly all of that is tax rather than St. Louis. Local prices are already working for you here, which is why this reads as tight rather than worse.
