Take-home pay only tells part of the story. New Hampshire has a cost of living index of 108 while Wisconsin is at 93 (national average = 100).
The cost of living gap is moderate. After adjustment, $100K has purchasing power of $73,264 in New Hampshire vs $79,734 in Wisconsin. However, Wisconsin actually provides better purchasing power despite New Hampshire’s take-home advantage.
For a single earner at $100K filing jointly, take-home becomes $84,710 in New Hampshire and $79,738 in Wisconsin \u2014 a difference of $4,973. The gap remains similar regardless of filing status.
On paper, moving from Wisconsin to New Hampshire would save $4,973/year on a $100K salary, or $24,863 over 5 years. But relocation involves real costs: moving expenses, potentially buying/selling a home, changing jobs, and adjusting to a new community.
The $4,973/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.
