What is Oklahoma City's cost-of-living index?

Oklahoma City has a composite cost-of-living index of about 87, where the US national average equals 100. That means a typical basket of expenses costs roughly 13% less in OKC than in an average American city.

Which category makes Oklahoma City cheap?

Housing is the biggest driver. OKC's housing sub-index sits near 75 versus the national 100, a 25% discount. Groceries, utilities, and healthcare are much closer to the national average, so housing does most of the affordability work.

How does the calculator convert my budget?

It splits a US-average budget into category weights — housing, groceries, transportation, utilities, healthcare, and other — then scales each slice by Oklahoma City's index for that category. Summing the scaled slices gives your OKC-equivalent monthly cost.

Is an index of 87 good for a major city?

Yes. Among large US metros, an index of 87 is notably affordable. Many coastal cities exceed 130 or 150, so a salary that feels tight elsewhere stretches considerably further in Oklahoma City.

Does this include taxes?

The composite index reflects typical consumer expenses rather than income taxes. Oklahoma's moderate state income tax and 8.625% OKC sales tax are separate factors you would layer on for a full picture.

Oklahoma City is one of the more affordable large US metros, with a composite cost-of-living index around 87 against a national average of 100. This tool shows that index broken out by category and converts a reference monthly budget into what the same lifestyle would cost in OKC.

How it works

A cost-of-living index expresses local prices relative to the US average, where 100 is the national baseline. To translate a budget, the tool weights each spending category and scales it by Oklahoma City’s sub-index:

OKC composite     = 87  (US = 100)
housing 75 · groceries 96 · transport 92 · utilities 95 · healthcare 99

OKC-equivalent cost = Σ ( budget × category weight × OKC index / 100 )

Because housing carries the largest weight and the deepest discount, it pulls the whole composite well below the national average.

Example

A $4,000 US-average monthly budget maps to roughly $3,480 in Oklahoma City, a saving of about $520 per month — driven almost entirely by the lower housing sub-index.

Notes

These are index-based estimates from survey data, not a personalized budget. Your actual costs depend on neighborhood, lifestyle, and household size. Income and sales taxes are separate from the consumer-price index shown here.
