What that actually means in Illinois
- Illinois is cheaper than the country as a whole, ranking 19 nationally on price. Prices sit about 1.14% below average, so a hundred dollars of shopping costs $99. Small on any one purchase. Considerable across a year of them.
- Housing is what makes Illinois affordable. Prices overall sit about 1.14% from the national average, but housing is about 7.6% from it — much further. The things you buy in a store here cost close to what they cost anywhere. It is the roof that is cheap, and the roof is most people's largest bill.
- What does that do to a salary? Seventy-five thousand dollars, earned and spent in Illinois, goes as far as $75,869 would at average American prices. Tax is a separate subject and comes out on top of this.
- Prices in Illinois run about 1.14% below the national level, placing it 19 nationally. The one-hundred-dollar national-average basket costs $99 in-state. The parity is a fixed-basket price comparison, so the gap represents genuine purchasing power rather than a difference in what residents choose to buy.
- Illinois's housing component sits about 7.6% below the national level against an all-items figure of about 1.14%, a divergence of about 6.46% and a housing rank of 22 nationally. Goods parities vary little between states because tradeable items arbitrage; shelter cannot, so it carries most of the observed dispersion. The consequence is that this state's affordability advantage accrues disproportionately to renters and buyers rather than to consumers generally.
- Adjusting seventy-five thousand dollars for Illinois's all-items parity yields $75,869 in constant national purchasing power. ⚠️ The figure is pre-tax and price-only; income, sales and local taxes are additional and independent of the parity. Nominal wage levels also correlate with parities in practice, so a full comparison of two states requires the local salary for the same role alongside this adjustment.

Where the difference actually sits
Each line compares Illinois with the national average for that kind of spending. The overall figure is the three above it, weighted the way a typical household spends — which is why housing can pull it a long way on its own.
| What you spend on | Against national average | Includes |
|---|---|---|
| Housing | -7.6% | Rent and owners’ equivalent rent |
| Goods | 0.88% | Groceries, fuel, clothing |
| Other services | 0.46% | Haircuts, repairs, childcare |
| All items | -1.14% | The three above, weighted |
What a salary is worth here
A salary of seventy-five thousand dollars, spent at Illinois prices, buys what $75,869 would buy at national average prices. That is a price adjustment only. No tax of any kind has been taken off it, and tax is a separate bill on the same money.
What this page cannot tell you
- This is one number for the whole of Illinois, and no state is one place. A big city and a rural county can sit far apart on every figure here.
- These prices were measured in 2023. Rents in particular can move a long way in a couple of years.
- And this is prices only. It says nothing about what Illinois charges you in tax, which is a separate bill and is covered elsewhere on this site.
- These parities are state-level aggregates. BEA also publishes metropolitan-area parities, and within-state dispersion between a large metro and a rural area routinely exceeds the difference between two states — so a state figure should not be read as descriptive of any particular address in Illinois.
- The underlying survey vintage is 2023, which is the most recent BEA publication rather than a current reading. Shelter parities are the component most exposed to drift between vintages, so recent local rent movements in Illinois will not be reflected here.
- Price parity and tax burden are independent quantities and this page models only the first. A low-parity state with high income tax and a high-parity state with none can leave a household in the same real position; comparing Illinois to another jurisdiction requires both figures, not either alone.
Questions people ask
What does a lower cost of living actually get me?
Room that a bigger salary elsewhere might not buy. A hundred dollars here does the work of $99 at national prices.
Which part of living here is actually different?
Where you live, not what you buy. Goods prices barely move between states; housing swings enormously, and it is doing most of the work in this state's figure.
How should I compare a job offer here with one somewhere else?
Convert both offers to the same terms first. Adjusted for prices, a reference salary behaves like $75,869 in Illinois; income tax then moves it again, independently.
How does a below-average price level translate into real income?
Illinois's all-items parity is at or below the national average, so nominal income understates purchasing power: one hundred dollars purchases $99 of national-average consumption. ⚠️ Parity measures prices, not availability or quality, and does not capture differences in the composition of what is bought.
Which component drives this state's parity?
The housing parity dominates Illinois's all-items figure, diverging from the national average by more than twice the goods component. Tradeable goods arbitrage across state lines and therefore cluster near parity; housing is non-tradeable, so its parity spans a far wider range and drives most interstate variation in the headline index.
How should nominal offers be adjusted across states?
Nominal offers should be deflated by the destination parity before comparison; the reference salary is equivalent to $75,869 in national-average terms here. ⚠️ Price adjustment and tax adjustment are independent and must both be applied — a state may be simultaneously cheap and heavily taxed, or the reverse.
