Lets say someone bets the pot and then someone else calls.

You hold the Ace high flush draw. The board is not paired and there is no straight flush possibility. You are also last to act.

It would make sense to call this then, correct? Since flush draw odds are 1:3 and the pot is laying you 3:1. You are at least even money if you call plus whatever other bets are made. Or would you need another caller to be profitable?

Also, what I have been attempting as of late is to bet the pot on the flop with an ace or king high flush draw when I'm in position and it's been checked to me. If someone reraises me I then push all-in. I figure I have a 36% to make the flush and If I don't I only need my opponent to fold 14% of the time to at least be even money in the long run. Since I otherwise maintain a tight table image I've found this to be fairly profitable so far.

I most likely messed up the math here so feel free to berate me.
