For a non-union actor, there is no average. Producers can offer whatever they wish and the actor accepts it or doesn't. For union, there are rates corresponding to different size roles, daily rates (example$125 a day), weekly rates ($600 a week). Generally , an actor's quote, or minimum salary, is whatever they made on their last major project.
I have made as little as $25 per performance of a play to making $8000 a week on a soap opera. And everything in between.
