If you factor in your time, it is generally not profitable (unless you can do nothing but minimum wage work, which I assume is not the case)
Factor in your time? You do know that there is no human work involved in the mining for bitcoins. You dont literally swing a pick axe. It is true that electricity costs can cut into profits. But time? Just have the computer mine when you don't need to use it.

Sorry for being harsh, I had assumed this was a one-shot thread. Since you're here though-- a little edumacation for ya'.
The time it takes out of your personal day to run your GPU/CPU miner is 0. Maintenance might be required once in a while, but if your error handling is keen-- 0.
The time it takes to set up such a machine in the first place-- assuming the hardware is there, but without drivers or miner app?
3 minutes flat. Raise that to 6 if you aren't satisfied with default settings.
I recently finished version 2.1.22 of my AlgoCalc solutions program. Basically, you pop in a thumbdrive and if autorun is in place, 3 minutes later you've got a silent miner that continuously runs on startup, runs invisibly, only uses non-used CPU/GPU (per miner plugin) with the option for delete protection (kind of like spyware cannot be 'deleted').
Get my app and the licensing it requires (per install), and you can have an install CD/Thumbdrive/fileset that you can put on any computer anywhere and it will act as your personal miner from then on. It is secure because it will not allow incoming connections, but it will connect to my algocalc database to make sure it is licensed, the same database that holds all of your pool mining login information for your convenience.
So this time you're talking about.... since I can add 500 computers a day (if I can find them), and each one can make $1 a day.. what time? You'd be stupid to stop mining. But then again, stupidity is just the lack of education. So I'm educating you.
Assuming you're not paying for the electricity of the computers running those stealth installations, that's theft.
You're making other people pay for your profit, without telling them.
