I'll briefly explain it in words:
The premium members, who's names are usually in bold, purchase tokens at a cost between $0.08-0.10 each, depending on the size of their package (200 tokens for 19.99, 900 for 74.99). The models receive a flat rate of $0.05/token. You're paid on the 16th and the 1st of each month, regardless of the length of the month. Members spend approx 60% of their cash on you, and approx 40% of it goes to maintaining the site - or so the site claims.
There's a thread here for charts: viewtopic.php?f=15&t=6906
Hope this helps.
I'm just going to add on that there are minimum payouts, depending on how you get paid. Also, sometimes you can be charged to accept your money! (crazy stuff). Here's a short list taken from the wiki:Direct Deposit:
Free, $20 minimumDomestic Wire Transfer:
Free (unless your bank charges you), $100 minimumCheck in the mail:
Free, $20 minimumInternational Wire Transfer:
Costs $15, $1000 minimumPayoneer:
Free, $20 minimumAlertPay, Paxum and OKPay
are all free with a minimum of $10.
So that means if you just dabble around a bit and you don't make the minimum amount of money, you won't ever see it. I have direct deposit and I've never been close to not making minimum payout, so if you have a bank account that's what I'd go for.
