I had some questions regarding the Huckel calculator - specifically, why
the Pi energy increases when you add an electron withdrawing
substituent onto a benzene ring.

It means that  the " pi electrons " of the electron withdrawing substituent  will occupy bonding molecular orbital(s) similarly to the pi electrons of the benzene ring.
