St. Louis remains relatively affordable compared with many U.S. metropolitan areas, but the amount you need depends on your household, neighborhood, transportation, and whether a figure refers to St. Louis city or the wider metro. This guide uses current 2026 regional indices, official rent benchmarks, and household budget estimates to build a clearer monthly plan.
Quick Answer
St. Louis remains less expensive than the national average, mainly because housing and transportation cost less. For one adult with no children, MIT estimates a 2026 living wage of $21.79 an hour, or $45,320 before tax. A practical comfort target is roughly $50,000 to $55,000, depending on rent, debt, benefits, and savings goals.
Key Takeaways
- The St. Louis MO-IL metro cost-of-living index was 89.8 in Q1 2026, about 10.2% below the U.S. benchmark.
- Housing and transportation are the metro’s largest cost advantages, while its healthcare index is slightly above the national benchmark.
- Revised FY2026 HUD gross rents are $955 for a studio, $995 for one bedroom, and $1,218 for two bedrooms.
- MIT estimates that one adult without children needs about $3,777 in gross monthly income to cover basic needs and estimated taxes.
- Families need considerably more because childcare, food, medical care, and housing requirements rise with each child.
Note: St. Louis city, St. Louis County, the St. Louis MO-IL metropolitan area, and Missouri statewide are different geographic areas. Figures below identify the geography and measurement whenever possible so that unrelated numbers are not treated as direct comparisons.
Cost of Living Overview for St. Louis, MO
The Missouri Economic Research and Information Center reported a Q1 2026 cost-of-living index of 89.8 for the St. Louis MO-IL metro. An index of 100 represents the participating-area national benchmark, so 89.8 indicates that the metro’s measured costs were approximately 10.2% lower overall.
| Category | Q1 2026 Index | Compared With 100 |
|---|---|---|
| Overall | 89.8 | 10.2% lower |
| Groceries | 98.7 | 1.3% lower |
| Housing | 80.4 | 19.6% lower |
| Utilities | 98.0 | 2.0% lower |
| Transportation | 88.8 | 11.2% lower |
| Healthcare | 103.6 | 3.6% higher |
| Miscellaneous goods and services | 90.4 | 9.6% lower |
Housing provides the largest advantage in this comparison. Groceries and utilities are much closer to the national benchmark, while the healthcare category is slightly higher. A person’s actual bills can still differ because the index represents a standardized comparison rather than a guaranteed household budget.
St. Louis’s affordability advantage comes mainly from housing and transportation, not from every category being cheaper.
Monthly Budget Examples by Household Type
The MIT Living Wage Calculator estimates the income required to cover basic needs in the St. Louis metro. It is not a luxury or upper-middle-class budget. The estimate includes basic housing, food, medical care, transportation, internet and mobile service, civic participation, other necessities, and estimated taxes.
| Household | Annual Income Before Tax | Gross Monthly Equivalent |
|---|---|---|
| 1 adult, no children | $45,320 | About $3,777 |
| 1 adult, 1 child | $80,129 | About $6,677 |
| 2 working adults, no children | $61,957 combined | About $5,163 combined |
| 2 working adults, 1 child | $92,243 combined | About $7,687 combined |
| 2 working adults, 2 children | $113,497 combined | About $9,458 combined |
Family costs rise sharply because childcare, food, healthcare, transportation, and housing needs increase. Two households with the same number of people may also need different incomes when one has employer-paid insurance, a paid-off vehicle, remote work, or free family childcare.
Housing: Rent, Home Prices and Mortgage Costs
Housing is usually the largest part of a St. Louis budget, but different sources measure it differently. A Fair Market Rent is not the same as an average advertised rent, and a Census home value is not the same as a current listing price. Compare figures only after checking the geography, housing type, date, and whether utilities are included.
Average Rent Levels
The U.S. Department of Housing and Urban Development publishes Fair Market Rents for rental assistance and housing analysis. HUD generally defines these as gross rents, meaning rent plus tenant-paid utilities other than telephone, cable, and internet.
| Unit Size | Revised FY2026 HUD Gross Rent |
|---|---|
| Studio | $955 per month |
| 1 bedroom | $995 per month |
| 2 bedrooms | $1,218 per month |
| 3 bedrooms | $1,568 per month |
| 4 bedrooms | $1,812 per month |
These figures apply to the St. Louis MO-IL HUD Metro FMR Area and are not promises that every apartment will be available at those prices. Renovated units, popular neighborhoods, short leases, pet-friendly properties, and buildings with extensive amenities may cost more.
For another benchmark, Census QuickFacts reports a median gross rent of $997 for St. Louis city based on 2020–2024 survey data. The close relationship between that historical city figure and the FY2026 one-bedroom HUD benchmark does not make them identical measurements.
Pro Tip: Before signing a lease, ask for the full recurring monthly amount, including base rent, water, sewer, trash, parking, pet rent, required internet packages, renter’s insurance, and any billing or amenity fees.
Buying vs. Renting
Census data for 2020–2024 reports a median owner-occupied home value of $197,500 in St. Louis city and selected monthly owner costs of $1,487 for homes with a mortgage. These are survey benchmarks rather than current asking prices, so buyers should compare recent sales in the exact neighborhood and property type they are considering.
The Freddie Mac Primary Mortgage Market Survey reported an average 30-year fixed mortgage rate of 6.58% on July 23, 2026. At that rate, a $200,000 home with 10% down would create an estimated principal-and-interest payment of about $1,147 per month on a 30-year loan.
That payment does not include property tax, homeowners insurance, maintenance, closing costs, homeowners association dues, or possible private mortgage insurance. Renting may therefore be less expensive in the short term even when the mortgage principal-and-interest amount looks close to rent.
The common 30% housing guideline can help with an initial affordability check, but it is not a guarantee that a home is affordable. A household with childcare, medical costs, student loans, or high transportation expenses may need to keep housing below 30%, while a debt-free household may have more flexibility.
Groceries and Typical Food Costs
St. Louis’s Q1 2026 grocery index was 98.7, only 1.3% below the national benchmark. Food is therefore close to average even though the metro’s overall cost of living is lower.
MIT allocates $4,520 per year, or about $377 per month, for food for one adult without children in the St. Louis metro. This is a basic at-home food allowance. Frequent restaurant meals, delivery fees, specialty diets, alcohol, and premium grocery stores can raise the total considerably.
Build a more personal estimate by tracking four weeks of actual food spending. Separate groceries from restaurants and household supplies, then adjust for seasonal purchases, work lunches, and guests. Families should use a household-specific estimate rather than multiplying a single-adult budget by the number of people because food requirements vary by age.

Utilities and Monthly Household Bills
The St. Louis metro utility index was 98.0 in Q1 2026, approximately 2% below the participating-area national benchmark. Your actual bill depends more on the home’s size, insulation, heating system, thermostat settings, number of occupants, and which services the landlord includes.
A complete utility budget may need to cover:
- Electricity
- Natural gas or another heating fuel
- Water and sewer
- Trash service
- Internet
- Mobile phone service
- Renter’s or homeowners insurance
MIT’s one-adult St. Louis budget allocates $1,457 per year, or approximately $121 per month, for internet and mobile service. Electricity, heating, water, and other household utilities are incorporated through the housing methodology rather than presented as an additional universal bill.
Note: Do not automatically add a separate full utility estimate to a rent benchmark described as “gross rent.” First confirm which utilities that benchmark or lease already includes, or you may count the same expense twice.
Homeowners should also reserve money for maintenance and major systems. Regular inspections may reduce the chance of an unexpected furnace replacement cost, but routine maintenance cannot eliminate every repair.
Healthcare Costs and Medical Expenses
Healthcare should not be described as universally cheaper in St. Louis. MERIC’s Q1 2026 healthcare index was 103.6, approximately 3.6% above the participating-area national benchmark.
MIT estimates annual medical costs of $3,375 for one adult without children in the St. Louis metro, or about $281 per month. That broad allocation is more useful for planning than a single doctor-visit price because medical spending can include insurance premiums, copays, prescriptions, dental care, vision care, and other out-of-pocket costs.
Your amount may be much lower when an employer pays a large share of the premium, or much higher when you buy coverage independently, use regular prescriptions, support children, or have ongoing medical needs. Compare the deductible, copays, coinsurance, provider network, and annual out-of-pocket maximum rather than looking only at the monthly premium.

Transportation: Driving, Public Transit and Auto Costs
Transportation is one of St. Louis’s stronger cost advantages. The metro’s Q1 2026 transportation index was 88.8, about 11.2% below the national benchmark.
MIT still allocates $8,875 per year, or about $740 per month, to transportation for one adult without children. That estimate reflects more than gasoline. A realistic vehicle budget may include:
- Vehicle purchase or depreciation
- Loan payments
- Insurance
- Fuel
- Registration and taxes
- Routine maintenance
- Tires and unexpected repairs
- Parking and tolls
Drivers should maintain a repair reserve for expenses such as a damaged windscreen or a failed water pump.
Residents who can use transit may spend less. Current Metro Transit fares include $1 for a MetroBus cash fare, $2.50 for a MetroLink cash fare, $5 for a one-day pass, $27 for a seven-day pass, and $78 for a 30-day pass. Commuters should still consider first-mile transportation, occasional rideshares, and travel outside the transit network.
Goods, Services and Lifestyle Expenses
The St. Louis miscellaneous goods-and-services index was 90.4 in Q1 2026, about 9.6% below the national benchmark. This category can include clothing, personal care, household items, recreation, and other purchases, but it should not be treated as one fixed monthly bill.
For one adult, MIT’s basic-needs estimate includes approximately $279 per month for civic participation and $379 per month for other necessities. These categories support modest participation in community life and essential purchases; they do not represent an unlimited entertainment allowance.
Costs a Basic-Needs Budget May Not Cover
A basic-needs estimate may leave little or no room for several irregular or optional expenses, including:
- Consumer debt and student-loan payments
- Retirement contributions and long-term investing
- A large emergency fund contribution
- Vacations and frequent restaurant meals
- Specialized legal expenses, such as a pardon lawyer cost
- Major repairs beyond a routine maintenance allowance
- Business startup expenses, such as the cost of opening a skating rink
Add these expenses separately rather than assuming that a regional cost-of-living percentage already covers them.
What Salary You Need to Live in St. Louis
Basic-Needs and Comfortable Salary Estimates
MIT estimates that one adult without children needs $21.79 per hour, or $45,320 per year before tax, to cover basic needs in the St. Louis metro. This is a living-wage benchmark, not a promise of a comfortable lifestyle.
For more flexibility, a single adult may reasonably target approximately $50,000 to $55,000 before tax. That range is a planning estimate created by adding roughly a 10% to 20% margin above the basic-needs figure. It can provide more room for savings, debt payments, rent above the benchmark, travel, or unexpected expenses.
Missouri’s 2026 minimum wage is $15 per hour. At 40 hours per week for 52 weeks, that equals $31,200 before tax, which is $14,120 below MIT’s one-adult basic-needs estimate. Actual annual income may be lower when hours fluctuate or unpaid time off occurs.
Budget Breakdown by Category
The following monthly breakdown converts MIT’s annual one-adult estimates into rounded monthly amounts.
| Category | Approximate Monthly Amount |
|---|---|
| Housing | $954 |
| Food | $377 |
| Medical | $281 |
| Transportation | $740 |
| Civic participation | $279 |
| Internet and mobile | $121 |
| Other necessities | $379 |
| Estimated taxes | $646 |
| Required gross income | About $3,777 per month |
Warning: These figures are general planning estimates, not individualized financial advice. Your required income can change substantially because of taxes, insurance coverage, debt, disability needs, childcare, employer benefits, savings goals, and the exact home or neighborhood you choose.
How to Build Your St. Louis Budget
- Choose the correct geography. Decide whether you are considering St. Louis city, a county suburb, or another part of the metro.
- Get a complete housing quote. Include rent or mortgage, utilities, parking, insurance, deposits, application fees, moving costs, and pet charges.
- Estimate transportation from your actual commute. Compare driving, public transit, remote work, and mixed transportation rather than using gasoline alone.
- Use household-specific food, medical, and childcare figures. A single-adult estimate cannot accurately represent a family.
- Calculate take-home pay. Account for federal, state, and local taxes, payroll deductions, health premiums, and retirement contributions.
- Add personal obligations. Include debt payments, child support, education, subscriptions, travel, and irregular repairs.
- Create a buffer. Add emergency savings and a margin for rent increases, insurance renewals, medical bills, and other unpredictable costs.

How much is a one-bedroom apartment in St. Louis?
The revised FY2026 HUD Fair Market Rent for a one-bedroom unit in the St. Louis MO-IL HUD Metro FMR Area is $995 per month as a gross-rent benchmark. Actual advertised rents may be higher or lower depending on neighborhood, condition, amenities, lease length, and included utilities.
Is healthcare cheaper in St. Louis?
Not according to every measure. MERIC’s Q1 2026 healthcare index for the St. Louis metro is 103.6, about 3.6% above the national benchmark in that dataset. Individual costs still depend heavily on insurance, medical needs, providers, and employer benefits.
Is it cheaper to rent or buy in St. Louis?
Renting normally requires less cash upfront and avoids direct maintenance costs. Buying may make sense for a financially stable household planning to remain long term, but the comparison must include interest, taxes, insurance, maintenance, closing costs, and possible private mortgage insurance.
How much does a family need in St. Louis?
MIT estimates that two working adults need about $92,243 combined before tax with one child and $113,497 with two children. A single adult with one child needs about $80,129. Childcare and household size are major reasons the amounts exceed the one-adult estimate.
Is St. Louis an affordable place to live?
St. Louis is relatively affordable by national standards. Its Q1 2026 metro cost-of-living index was 89.8, about 10.2% below the benchmark. Housing and transportation provide most of the advantage, while groceries and utilities are closer to average and healthcare is slightly above it.
