Take-home pay only tells part of the story. New Jersey has a cost of living index of 115 while North Carolina is at 95 (national average = 100).
This is a substantial difference. After adjusting for cost of living, $100K in New Jersey has purchasing power of $62,728 compared to $79,089 in North Carolina. North Carolina wins on both raw take-home and cost-adjusted purchasing power, making it the clear winner for a $100K earner.

On paper, moving from New Jersey to North Carolina would save $2,998/year on a $100K salary, or $14,988 over 5 years. But relocation involves real costs: moving expenses, potentially buying/selling a home, changing jobs, and adjusting to a new community.
The $2,998/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.
