Take-home pay only tells part of the story. Oklahoma has a cost of living index of 87 while Wyoming is at 94 (national average = 100).
The cost of living gap is moderate. After adjustment, $100K has purchasing power of $87,586 in Oklahoma vs $84,176 in Wyoming. However, Oklahoma actually provides better purchasing power despite Wyoming’s take-home advantage.
For a single earner at $100K filing jointly, take-home becomes $81,785 in Oklahoma and $84,710 in Wyoming \u2014 a difference of $2,925. The gap remains similar regardless of filing status.
On paper, moving from Oklahoma to Wyoming would save $2,925/year on a $100K salary, or $14,625 over 5 years. But relocation involves real costs: moving expenses, potentially buying/selling a home, changing jobs, and adjusting to a new community.
The $2,925/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.
