Hi,
Formal Charge = [# of valence electrons on atom] – [non-bonded electrons + number of bonds].
Let’s apply it to :CH3 (one to the right from BH4)
The number of valence electrons for carbon is 4
The number of non-bonded electrons is two (it has a lone pair)
The number of bonds around carbon is 3.
So formal charge = 4 – (2 +3) = 4 – 5 = –1
The formal charge of C in :CH3 is negative 1.
