You probably run a bigger (perhaps double) neutral and care about a stronger ground. But yeah, the $12 is rounding error at this scale

In the US, you don’t need a neutral for a 240V 50A circuit on a residential single-phase service, there are two line conductors (120V to ground) both connected to a 2-pole single-phase breaker, line-to-line between the two is 240V.

You would need a neutral if it was a 208/120V three-phase service.

Neutrals and grounds are sized per the NEC, neutrals are the same size as the line conductors and equipment grounds are sized off of a table.

#6 conductors and #10 ground is what the NEC calls for.
