A holdem odds calculator works by doing the basic math for you.
Whenever you play a poker game and are in a hand, the calculator software will tell you how likely you are to improve your hand and how likely you are to win the pot if you do improve.
A good holdem odds calculator takes into account the actions from your opponents and adjusts its hand ranges accordingly, so your poker odds calculations are not against random cards, but against a specific likely hand range.
