Understanding Poker Odds

Making profitable poker decisions requires understanding your chances of winning and comparing them to the pot odds you're getting.

What Is Equity?

Equity is your mathematical share of the pot based on your probability of winning. If you have 60% equity, you should win the pot 60% of the time on average. Equity changes as more community cards are revealed.

Counting Outs

Outs are cards that can improve your hand. For example, with a flush draw you have 9 outs (13 suited cards minus 4 you can see). The Rule of 2 and 4 estimates your chance: multiply outs by 2 for one card to come, or 4 for two cards.

Pot Odds Explained

Pot odds compare the cost of a call to the potential reward. If the pot is $100 and you must call $20, you're getting 5:1 odds (20%). You need at least 20% equity to break even on the call. If your equity exceeds the required equity, calling is profitable long-term.

Frequently Asked Questions

With 10,000 simulations, results are typically accurate within 1%. For more precision, increase the simulation count to 25,000 or 50,000. The calculator runs random scenarios and calculates how often each outcome occurs.

An opponent's range is the set of hands they might hold based on their playing style. A "tight" player only plays premium hands like big pairs and AK, while a "loose" player might have almost any two cards. Choosing the right range dramatically affects your equity calculation.

Use pot odds whenever you face a bet and need to decide whether to call. Enter the current pot size and the bet amount. If your equity exceeds the required equity (pot odds percentage), calling is mathematically profitable in the long run.
