Can the admins in lemmyworld capture some data on what the real cost of hosting a Lemmy and what the user capacity is like?

I’d consider hosting a federated servers for my friends and I would like to know some tangible parameters on how big I could go.

Edit: Thanks everybody! Seems like a standard VPS is the go to. I think I have the wherewithal to do this at some point with my skill set. Will start looking into it.
