One of the things that can be a tough one for a voiceover to figure out is how much to charge. If you are an AFTRA or SAG member, that's easy. You get paid what the rate card says. For non-union guys like me, it's a little less clear.
I have adopted the Voices.com recommended rates for my work. I think you will find them fair and well balanced for most of the typical voiceover work. Of course, everything is negotiable. :)
