For the most part, I use T&M. On the last few jobs, I have gotten burned b/c the was not contract. Now I have learned my lession and on bigger jobs I give contracts. I have been losing most of them b/c I was too high. I am going to just use round numbers for an example because every ones labor rates are diffent.
If I charge $50 per hour for T&M, would I use that amount to figure lets say a large addition and remodel? Or would I figure my Cost rate, $25 per hour and add a percent to that. In other words discount my full rate.
What about new houses. Every one uses an opening price. How is that figured?
