Depends, cheaper for kids, for adults usually around the price of a nicer rock climbing gym or like a premium ish gym (cheaper than someplace like equinox, pricier than somewhere like crunch)
Tournaments super pricy but optional
Equipment is dumb expensive but most places will let u rent or borrow and you need to use shitty equipment anyways till u know what u like. Then u usually get it piece by piece. But once u get it, it’ll last ur entire life unless ur like an athlete lol.
It’s solo equipment only usually so u don’t need to worry about things like organizing a pitch or getting nets and goals and whatever, everyone brings their own stuff and the gym provides whatever else would be needed
