Take-home pay only tells part of the story. Illinois has a cost of living index of 93 while Nevada is at 101 (national average = 100).
The cost of living gap is moderate. After adjustment, $100K has purchasing power of $79,758 in Illinois vs $78,342 in Nevada. However, Illinois actually provides better purchasing power despite Nevada’s take-home advantage.
For a single earner at $100K filing jointly, take-home becomes $79,760 in Illinois and $84,710 in Nevada \u2014 a difference of $4,950. The gap remains similar regardless of filing status.
On paper, moving from Illinois to Nevada would save $4,950/year on a $100K salary, or $24,750 over 5 years. But relocation involves real costs: moving expenses, potentially buying/selling a home, changing jobs, and adjusting to a new community.
The $4,950/year savings is meaningful but probably not enough to justify a move on its own. However, combined with other factors like career growth, lifestyle preferences, or family proximity, it could tip the scale.
