I don't think so. You need to do two calculations. One is how many outs you have in relation to the cards left and two the money you are asking to be put in in relation to the size of the pot. I don't think there is an easy way to do this other than rounding off but you will lose some accuracy.

One other thing, this sort of mathematical assessment of every bet you make is used mostly in Limit. In No Limit, if I had a nut flush draw and a pair and an ace in my hand, I would probably put it a good raise in previous example, depending of course on the opponent. So odds are not really relevent when you do that. You're looking to win the pot with a semi-bluff. I find this happens more often then me figuring out calling odds in NL. As a matter of fact, I am usually raising my drawing hands in NL. In Limit, I'm constantly doing the math in my head.

This is one of the reasons that Holdem is a difficult game to master.

So basically in NL you're better off just paying attention to your outs and determining how much of your stack you want to risk based on that percentage?

No...

The size of the bet in comparison to the pot.
