The same $4,000 monthly lifestyle that defines “average” in America costs about $3,470 in Oklahoma City. OKC’s composite cost-of-living index of 87 (US average = 100) makes it one of the most affordable large metros in the country — and unusually, the discount comes almost entirely from one line item: housing at index 75. This tool breaks the composite into category sub-indices and converts a reference monthly budget into what the same lifestyle costs in OKC.
Reading the index
A cost-of-living index expresses local prices relative to the US average, where
100 is the national baseline. An index of 87 means a comparable basket of
goods and services costs about 13% less than the US average overall.
The tool weights each spending category and scales it by Oklahoma City’s sub-index for that category:
OKC composite index = 87 (US national = 100)
Sub-indices (approx):
Housing = 75 (deepest discount)
Groceries = 96 (near national average)
Transportation = 92
Utilities = 95
Healthcare = 99 (near national average)
Miscellaneous = 95
OKC cost = Σ (reference budget × category weight × OKC sub-index ÷ 100)
Housing’s large budget share and steep 25% discount do most of the heavy lifting, pulling the composite well below 100 even though other categories are close to average.
Worked example
A $4,000 US-average monthly budget broken into the tool’s categories and
weights:
| Category | US budget | OKC index | OKC cost |
|---|---|---|---|
| Housing (33%) | $1,320 | 75 | $990 |
| Groceries (13%) | $520 | 96 | $499 |
| Transportation (17%) | $680 | 92 | $626 |
| Utilities (8%) | $320 | 95 | $304 |
| Healthcare (8%) | $320 | 99 | $317 |
| Other (21%) | $840 | ~87 (composite) | $731 |
| Total | $4,000 | — | ≈$3,467 |
Estimated OKC monthly saving vs US average: about $533/month (≈$6,400/year). The housing line alone contributes $330 of it — more than every other category combined.
What the housing index of 75 means in practice
A housing sub-index of 75 means OKC housing costs run about 25% below the national average. In concrete terms, a property that would command $2,000/month nationally might rent for roughly $1,500 in a comparable OKC neighbourhood — or a home that might cost $400,000 in an average US market could be purchased for around $300,000.
Median home prices and rents do vary significantly across OKC’s sprawling metro:
- Edmond and Nichols Hills are among the pricier submarkets
- Midwest City, Del City, and South OKC typically come in below the metro median
- Downtown and Midtown OKC have seen rising rents as urban renewal has progressed
Oklahoma City vs comparable metros
| City | Composite COL index (approx) |
|---|---|
| Oklahoma City | ~87 |
| Tulsa, OK | ~83 |
| Kansas City, MO | ~90 |
| Dallas–Fort Worth | ~103 |
| Denver, CO | ~124 |
| Austin, TX | ~116 |
| National average | 100 |
OKC sits notably below the national average and well below the Sun Belt metros that have attracted significant migration.
What is not captured in the index
The composite index reflects typical consumer expenses. It does not include:
- Income and sales taxes. Oklahoma’s 4.75% top income tax rate and OKC’s ~8.625% combined sales tax rate would reduce take-home pay relative to a no-income-tax state like Texas, partly offsetting housing savings.
- Commute costs. OKC is car-dependent; households often run two vehicles, which can raise actual transportation costs above the index suggests.
- Neighborhood-level variation. A single metro index smooths over significant local differences.
These are index-based estimates from survey data. Your actual costs depend on neighbourhood, lifestyle, household size, and individual spending patterns.
Where to verify the numbers
Composite indices of this kind are modeled estimates, and they drift as markets move. Two federal datasets anchor the picture: the Bureau of Economic Analysis publishes Regional Price Parities comparing price levels across metros on a US=100 basis (OKC consistently prices below the national level there too, driven by housing), and the Bureau of Labor Statistics Consumer Price Index tracks how fast local prices are moving. For a relocation-sized decision, check both — and note that sub-index tables from commercial cost-of-living surveys (such as C2ER’s quarterly index) are what tools like this approximate.
