The Real Cost of Living in St. Louis (It's the Housing, Not Everything Else)
Revised July 28, 2026
What does it actually cost to live in St. Louis?
About 10% below the national average — and almost all of it is one category. Missouri’s own agency (MERIC) puts the St. Louis MO-IL metro at a composite of 89.8 for Q1 2026. But the components tell the real story: housing 80.4 (~20% cheaper), transportation 88.8, utilities 98.0 and groceries 98.7 (both roughly national), and health 103.6 — above national. ⚠️ Published estimates range from 2% to 10.4% below depending on whose basket you use, so don’t apply one percentage to your whole salary. 💡 MIT puts the living wage for one adult here at $21.79/hr against a $15.00 state minimum.

About 10% below the national average — and almost all of that discount is one category.
Missouri’s own state agency, the Missouri Economic Research and Information Center, puts the St. Louis MO-IL metro at a composite cost-of-living index of 89.8 for the first quarter of 2026, where 100 is the national average. Statewide, Missouri sits at 88.6, tied with Iowa for the seventh-lowest cost of living in the country.
But the composite hides the interesting part. Break it into components and St. Louis stops looking uniformly cheap:
| Category | St. Louis index | vs national |
|---|---|---|
| Housing | 80.4 | about 20% cheaper |
| Transportation | 88.8 | about 11% cheaper |
| Miscellaneous | 90.4 | about 10% cheaper |
| Utilities | 98.0 | roughly national |
| Groceries | 98.7 | roughly national |
| Health | 103.6 | more expensive |

So the honest summary is not “everything is cheap in the Midwest.” It is: your housing costs drop sharply, your grocery bill barely moves, and your health care costs go up.
Why every website gives you a different number
If you have already searched this, you have noticed the answers do not agree. We pulled the current page one and counted:
- Salary.com — about 2% below national
- Payscale — 6% below
- MERIC — 10.2% below
- Apartments.com — 10.4% below
Google’s own summary panel currently repeats the 2% figure. That is a five-fold spread on the same question, and none of these sources is lying.
They differ because a cost-of-living index is a basket, and everyone builds the basket differently. How much weight goes on housing versus groceries? Is it the city or the whole metro? Renting or owning? Change those and the answer moves several points.
Which is why we lead with MERIC here: it is a state agency, it is dated to a specific quarter, and it publishes the components rather than one blended number. You can see which parts are cheap instead of taking a single percentage on faith.
The practical takeaway is not to trust any one figure — including ours. Look at the category that dominates your budget. If you rent modestly and have a chronic condition, the health line matters more to you than the housing line, and your personal index looks nothing like 89.8.
What earning a living actually requires here
The MIT Living Wage Calculator estimates the living wage in the St. Louis metro at $21.79 an hour for one adult with no children. Missouri’s minimum wage is $15.00 as of January 1, 2026.
That gap — roughly $6.79 an hour, or about $14,000 a year at full time — is the honest shape of affordability here. St. Louis is genuinely inexpensive compared with the coasts, and a full-time minimum-wage job still does not reach a single adult’s baseline. Both things are true, and most cost-of-living pages only tell you the first one.
How St. Louis compares inside Missouri
Every participating Missouri city sat below the national average in Q1 2026:
- Joplin — 83.7, the lowest in the state, with housing at 59.8
- Springfield — 89.7
- St. Louis MO-IL — 89.8
- Columbia — 91.3
St. Louis and Springfield are effectively tied, which surprises people who assume a large metro must cost more than a smaller city. It does not, here — because the housing stock is old, plentiful, and spread across a very large area.
That last point deserves its own note, because it is where the metro’s averages become almost meaningless in practice.
The average is not a place you can live
“St. Louis” in these indexes means the whole MO-IL metro — the city, all of St. Louis County’s eighty-plus municipalities, St. Charles County, and the Illinois side. The spread inside that area is enormous.
Housing in Clayton and housing in Florissant are not the same market. A house in Belleville, Illinois and a house in Chesterfield are not the same purchase, and they are not even in the same state for tax purposes. The index averages all of it into one number that describes no actual neighborhood.
So use the index for the question it answers — is this metro cheaper than where I live now? — and then look at specific municipalities for the question you actually care about. Our guide to why St. Louis real estate is so affordable goes deeper on the housing side, which is where most of your savings live.
How to actually use this if you are comparing a job offer
Here is where most people misuse a cost-of-living index, and it can cost them real money in a negotiation.
The instinct is to take the composite and apply it to the whole salary — “St. Louis is about 10% cheaper, so I can accept about 10% less.” That is the wrong calculation, and depending on your situation it is wrong in either direction.
The composite is a weighted blend of six categories, and your household does not spend like the blend. Do it this way instead:
Split your current spending into the same six buckets — housing, groceries, utilities, transportation, health, everything else. Rough percentages are fine. Then apply each index to its own bucket rather than applying one number to everything.
Two examples of how differently that lands, both clearly hypothetical:
Someone spending half their income on rent gets most of the benefit. Housing at 80.4 is doing the heavy lifting, and it is the biggest slice of their budget, so their personal saving lands well above the headline 10%.
Someone with modest housing costs and high medical spending gets almost none of it. Their largest categories are groceries at 98.7, utilities at 98.0, and health at 103.6 — that is roughly break-even or slightly worse. For that household, moving here on a 10% pay cut is a real pay cut.
Same city, same quarter, same official numbers, opposite conclusions. Which is why the component table above matters more than any single percentage anyone quotes at you.
Two practical notes if you are running this exercise. Renting and buying are not the same bet. The 80.4 housing index reflects both, and a renter feels it immediately while a buyer feels it over years — alongside the maintenance costs of older housing stock. And health care weighting rises with age and household size. A 103.6 index on a small share of a young single person’s budget is noise; on a retired couple’s budget it is the headline.
Costs the index does not really capture
A few things surprise people who move here, none of which show up cleanly in a composite number.
Personal property tax on vehicles. Missouri counties assess an annual tax on cars, trucks and boats. Newcomers from states without it are reliably caught out by the first bill. Rates are set locally, so check with the assessor for the county you are moving to rather than assuming a figure.
Two states, two tax systems. The metro spans Missouri and Illinois, and where you live determines your income tax, your property tax, and your sales tax — while your commute may cross the river daily. If you are weighing sides, that comparison is worth doing properly rather than by rule of thumb.
Sales tax stacking. Missouri layers state, county, city and special district rates, so the rate at one shopping center differs from another a few blocks away. It is a small effect on a coffee and a real one on a car.
Older housing stock. The savings on the purchase price are real. So are the maintenance costs of a house built in the 1930s — sewer laterals, original wiring, foundations on clay soil. Budget for the house you are actually buying, not the index.
Utilities are an annual average hiding two extremes. The 98.0 index is a yearly figure, and St. Louis does not have a mild year. Summers are hot and genuinely humid, winters get cold, and the bills follow — so a household that budgets by the monthly average will be caught out twice a year. If you are moving from a temperate climate, ask a prospective landlord or seller for twelve months of actual utility bills rather than a typical month. In an older, poorly insulated house the gap between July and October is not small.
Car dependence outside the core. Transportation scores well at 88.8, but that assumes driving. Much of the metro has limited transit, so a household running two cars will not feel the transport discount the way the index implies.
So is it affordable?
For most people moving from a larger or coastal metro, yes — and the reason is specific rather than general. You will spend meaningfully less on housing, slightly less on getting around, about the same on food and utilities, and somewhat more on health care.
If you are moving here from elsewhere in the Midwest, the difference narrows to very little. And if you are already here on a lower income, the state ranking is cold comfort: a low cost of living and a wage that does not reach the local living wage still leaves a gap.
Both of those are the honest answer, and it is a more useful one than a single percentage.
Frequently asked questions
Is St. Louis affordable to live?
By the numbers, yes — the metro sits at a cost-of-living index of 89.8 against a national average of 100, and Missouri as a whole is tied for the seventh-lowest in the country. But the discount is concentrated in housing, at 80.4. Groceries and utilities run close to national, and health care is above it at 103.6.
What salary do you need to live comfortably in St. Louis?
There is no single honest figure, and published estimates vary widely because each uses a different basket. A useful floor: the MIT Living Wage Calculator puts the living wage for one adult with no children in this metro at $21.79 an hour. Comfort above that depends most on whether you rent or own, and in which municipality.
What is middle class income in St. Louis?
Definitions vary by source and none is authoritative, so treat any specific bracket cautiously. What is measurable is that local costs run roughly 10% below the national average overall, driven by housing, meaning a given income stretches further here than the same income in a coastal metro — but less far than the headline suggests once health care is included.
Is $40 an hour good in Missouri?
It is well above both the state minimum wage of $15.00 and the MIT living-wage estimate of $21.79 an hour for a single adult in the St. Louis metro. Whether it is comfortable depends on household size and municipality — the same wage supports a very different life in Joplin, at an index of 83.7, than in a higher-cost pocket of St. Louis County.
Why do different websites give different costs of living for St. Louis?
Because each builds a different basket and weights it differently. Current published estimates for St. Louis range from about 2% below national to about 10.4% below. MERIC, a Missouri state agency, is the one that publishes the underlying components by quarter, which is why its 89.8 composite is the most inspectable figure rather than simply the most favorable.
Is the cost of living the same across the St. Louis metro?
No, and the average can be misleading. The index covers the whole MO-IL metro — the city, more than eighty municipalities in St. Louis County, St. Charles County and the Illinois side. Housing costs, property taxes and sales tax rates all vary considerably between them, and the Illinois side sits under a different state tax system entirely.
