It tracks cities, so you figure which one is closest to where you live. I would use Gainesville for here and subtract maybe 5% more. Here is what happens when I plug in my hometown of Boston where I moved from and 100,000 income ...
If you move from Boston, MA to Gainesville, FL....
Groceries will cost: 9% less
Housing will cost: 33% less

Transportation will cost: 1% less
Healthcare will cost: 25% less
Not a perfect science, but it might help. Good Luck.
