Yeah adding them up is fine, but I think your general math is wrong. For example when you say
but a bet of 500 makes me think to immediately fold cause I have half the odds to hit that I am paying...
I get the impression you are calculating the pot odds incorrectly. You have to bet 500 into what will be a 2200 pot or 22.7%.. hardly double your odds..
