For residential, I start calculating at .30/sqft to .35/sqft when I am not moving furniture. I will bump the price up a lot if they want furniture moved and there are some things that I won't move.
I feel sure that prices vary from one area to the next. Also, I will vary the price depending on how much time I expect to spend on the job (level of soiling, cramped spaces, work around a lot of furniture, etc.) I'm not working my old butt just to break even, .
