1. Any uncalled bets that you have to call are factored in.

Thus if the pot if $50 and someone bets $10 and its your action you are getting 6-1 on your money (the $10 he bet is now part of the pot).

2. If there are players behind you, you may have to factor in the action behind you in your decision.

For example if you have the right odds to call 1 bet but not two, you need to be fairly certain no one behind you will raise the bet you are about to call.
