Take-home pay only tells part of the story. Connecticut has a cost of living index of 111 while Wyoming is at 94 (national average = 100).
This is a substantial difference. After adjusting for cost of living, $100K in Connecticut has purchasing power of $67,191 compared to $84,176 in Wyoming. Wyoming wins on both raw take-home and cost-adjusted purchasing power, making it the clear winner for a $100K earner.
For a single earner at $100K filing jointly, take-home becomes $80,167 in Connecticut and $84,710 in Wyoming \u2014 a difference of $4,544. The gap remains similar regardless of filing status.
On paper, moving from Connecticut to Wyoming would save $4,544/year on a $100K salary, or $22,718 over 5 years. But relocation involves real costs: moving expenses, potentially buying/selling a home, changing jobs, and adjusting to a new community.
The $4,544/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.
