1 gold is 30-35c to us. Some models get 30, and I believe some get 35. If you get daily ACH pay (US) it reduces your percentage by another 2 or 3 percent (lol when it's working correctly anyway).
Some models get talent scouted, and get offered a different deal still.
Majority get 30-35c per gold, unless they are working through a studio.
Other payment forms take various amounts. I think weekly ACH is $5 per week (in the countries it's offered). Biweekly paper checks are probably still free.
Having it wired within the us is either $25 or $35, per wire.
But like I said daily ACH, is the only one where they tell you a direct further percentage they will take, rather than a set fee.
If you are outside of the US and Canada I think you need to work with paxum or some other option like that, that can have bigger and varying fees.
