Not sure why you put your gear here, cause it's irevelant for that kind of calculation. All what is matter is how many time did you spend on this and what rate per hour you want to charge for your time.
Nobody cares if you made your music with Live, Reason, Fruity Loops or good old Impulse Tracker. Same with graphics, potential client do not need (and usually want) to know if you are using Paint or photoshop. What really matters is final product.
Reading your list I assume that if I would want to hire you for the job, I would need to pay you 3000$ and then 75$ for every hour you spend working for me.
Not the case at all. I'm simply tracking the figures and it doesn't have anything to do with what my rate would be since I wouldn't need to spend another $3000 on gear to work on a custom piece for someone. I included the gear because I couldn't make my music without it-- if I used some other gear or software, the music would be different--- for better or worse. That information is there for people who are curious (usually other musicians). When people hear it, they often ask what I'm using.
My rate for custom/exclusive work is $30 per composed minute, by the way, which takes me between 1-2 hours to complete depending on revisions, etc.
