Take-home pay only tells part of the story. Colorado has a cost of living index of 105 while Tennessee is at 90 (national average = 100).
The cost of living gap is moderate. After adjustment, $100K has purchasing power of $71,167 in Colorado vs $87,917 in Tennessee. The take-home winner also wins on purchasing power.
For a single earner at $100K filing jointly, take-home becomes $80,310 in Colorado and $84,710 in Tennessee \u2014 a difference of $4,400. The gap remains similar regardless of filing status.
On paper, moving from Colorado to Tennessee would save $4,400/year on a $100K salary, or $22,000 over 5 years. But relocation involves real costs: moving expenses, potentially buying/selling a home, changing jobs, and adjusting to a new community.
The $4,400/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.
