Minimizing formal charges leads to electrons being more evenly distributed rather than being concentrated in one area which leads to regions of negative charge.

A more symmetrical distribution contributes to the overall stability of the molecule, indicating why formal charges closer to zero are more stable.

How do you calculate formal charge again?

The formal is...

FC = V - (L + S/2)

Formal charge is calculated by subtracting the number of bonds plus the number of free electrons from the number of valence electrons of that atom. The sum of the number of bonds plus the number of free electrons can be thought of as the sum of the number of sticks (bonds) and dots (electrons).
