FWIW, I took the total number of US equity contracts I traded in May and divided by the total commissions for US equity contracts (IB breaks down commissions/fees by asset class, so was easy to do). Granted there are going to be differences affected by things such as some options I allowed to expire worthless, some I closed at <= $0.05 (IB charges no commission for these), and I've had trades where my exchange rebates are greater than my commissions, so keep that in mind. In any case, my average per contract cost was basically $0.50/contract. I don't do massive volume either. I'm on IB's $0.70/contract commission schedule (their lowest volume tier), so I must be getting rebates on a good chunk of my trades.
I'm assuming the other posters were primarily focused on stock rather than stock options, but figured my real world IB data might be useful to someone.
