Are commissions paid before or after profit splitting?

I was looking into a firm that had profit splitting for different amounts of money you put up. I forgot to ask but I was wondering if you pay commissions before or after the profit split? For example if i had a %50 payout and I made $100 that day and had $20 in commissions, would my payout be 100-20= $80, then split that 50/50 so my cut would be $40? Or does the split happen before commissions are paid and you pay the commissions out of your split? So it would be 100/2=50 then -20 for commissions so my cut would be $30?

 

Should be taken before the split. Some firms may be different though.

 

When i worked at a prop firm,you pay the commissions before the profit split. So to answer your question above,you would get $40,not $30.
