Poker Pot Odds & Equity Calculator
Calculates whether calling a bet is mathematically profitable by comparing your hand's equity to the pot odds offered. Use it on the flop or turn whenever you face a bet and are drawing to a winning hand.
About this calculator
Pot odds measure the ratio of the amount you must call to the total pot you stand to win. The break-even equity required to call is: required equity = betSize / (potSize + betSize). Your actual equity with outs remaining is estimated by the formula: equity ≈ 1 − ((47 − outs) / 47)^street, where 'street' equals 1 for a single card to come and 2 for two cards (flop). If your equity exceeds the required equity, the call is profitable in the long run. Implied odds extend this by adding expected future winnings from opponents when you hit your draw, effectively reducing the required equity threshold. Comparing these two values tells you definitively whether to call, raise, or fold.
How to use
Scenario: pot is $50, opponent bets $20, you hold a flush draw (9 outs) on the turn (1 card to come). Step 1: required equity = $20 / ($50 + $20) = 20/70 ≈ 28.6%. Step 2: actual equity = 1 − ((47 − 9) / 47)^1 = 1 − (38/47) = 1 − 0.809 = 19.1%. Step 3: 19.1% < 28.6%, so the call is unprofitable based on pot odds alone. Step 4: if you expect to win $40 more on the river when you hit, implied pot = $70 + $40 = $110; adjusted equity needed = $20/$110 ≈ 18.2%. Now 19.1% > 18.2%, making the call marginally profitable with implied odds.
Frequently asked questions
How do I count outs accurately in Texas Hold'em poker?
An out is any unseen card that completes your hand and makes it likely the best hand. A flush draw has 9 outs, an open-ended straight draw has 8, a gutshot straight draw has 4, and a pair drawing to trips has 2. Be careful not to count tainted outs — cards that complete your draw but give an opponent a better hand. For example, if you have a straight draw but three cards to a flush are on the board, some of your straight outs may complete an opponent's flush. Accurately counting clean outs is critical for meaningful equity calculations.
What is the difference between pot odds and implied odds in poker?
Pot odds are purely mathematical: the ratio of the current bet to the current pot, reflecting immediate profitability. Implied odds factor in the additional money you expect to win from your opponents on future streets if you complete your drawing hand. Implied odds are especially valuable in deep-stack games where opponents are likely to pay off big bets when you hit your draw. However, implied odds are subjective and depend on your read of your opponent's tendencies, so they should be estimated conservatively to avoid rationalizing bad calls.
When should I fold even if I have enough outs to call?
You should fold even with sufficient outs when your implied odds are negative — for example, if hitting your draw creates obvious board textures that cause opponents to check-fold, denying you future value. You should also fold when your 'outs' are not clean, meaning they may complete an opponent's stronger hand. Additionally, tournament ICM considerations can make mathematically neutral or even slightly profitable calls incorrect because the chip equity lost on a miss far outweighs the gain. Position also matters — calling out of position reduces your ability to control pot size after hitting.
