The real hit will be when I get a bill for the AFTRA initiation fee, though; it'll probably wipe out my earnings to date.
Update: They won't send me a bill. If I do more than a specific number of appearances in a certain length of time (the talent coordinator said she thought it was 3 in a month, but she wasn't sure), then I'll have to agree to send future pay to AFTRA until the initiation fee is paid. I get to keep the money I've already received.
