Example Calculation

How does spending power compare in Illinois?

At the national average cost of living (index 100), $75,000 buys the same lifestyle everywhere. Illinois's actual cost of living index is 95.1, so $75,000 in Illinois has the buying power of roughly $78,864 at the national average.

Result: The difference between the cheapest and most expensive states means the same salary can feel like a significant raise or pay cut depending on where you live. Housing accounts for 60–70% of this gap — it's the single biggest lever in location-based financial planning.
