What's an ideal maximum brokerage % on your trades?

I use CommSec where they charge $20 per trade under $10,000.



I'm in my twenties and am not swimming in the dough like a lot of guys investing in chunks of tens of thousands of dollars, so I'm generally investing around $1500 - $2500 per trade...so the brokerage is around 1%.



Just wondering what you guys think a good maximum brokerage percentage is for your trades. Obviously I know the more I invest the lower my percentage is, but is 1% considered a fair brokerage? Just looking for a bit of a guideline.



Thanks.
