About this calculator
Pot odds compare the amount you must call with the pot you stand to win. If the current pot (already including your opponent's bet) is P and the call is C, the pot after you call is P + C and the break-even equity is C / (P + C). Your chance of completing the draw is computed exactly from the unseen cards: on the flop 47 cards are unseen (52 minus your 2 and the 3 on the board) and two more come, so equity = 1 − ((47 − outs) / 47) × ((46 − outs) / 46); on the turn 46 cards are unseen and one comes, so equity = outs / 46. The calculator reports equity × (P + C) / C: the average amount you get back for every $1 you call. Above 1.00 the call is profitable on pot odds alone (your equity beats the break-even equity); below 1.00 it loses money. Variables: potSize (pot including the bet you face), betSize (amount to call), outs (unseen cards that complete your hand), street (2 cards to come on the flop, 1 on the turn). Edge cases: the flop figure assumes you will see both the turn and river for this one call, which is only true if you are all-in or the turn checks through. The math assumes every out wins (none is tainted, i.e. none also gives an opponent a better hand); subtract tainted outs first. Implied odds (money won on later streets) and reverse implied odds are not included.
How to use
Example 1: The pot is $50 and your opponent bets $20, so the current pot is $70 and you must call $20. You hold a flush draw (9 outs) on the turn. Step 1: break-even equity = $20 / ($70 + $20) = 22.2%. Step 2: your equity = 9 / 46 = 19.6%. Step 3: return per $1 = 0.196 × $90 / $20 ≈ 0.88. Below 1.00, so the call loses about 12 cents per dollar on pot odds alone. Example 2: The pot is $100 and your opponent bets $25 on the flop, so enter a pot of $125 and a call of $25 with an open-ended straight draw (8 outs) and two cards to come. Step 1: break-even = $25 / $150 = 16.7%. Step 2: equity = 1 − (39/47) × (38/46) = 31.5%. Step 3: return = 0.315 × $150 / $25 ≈ 1.89, so the call earns about 89 cents per dollar called.
Frequently asked questions
How do I count outs accurately in Texas Hold'em?
An out is any unseen card that completes your hand and likely makes it the best hand. A flush draw has 9 outs, an open-ended straight draw has 8, a gutshot has 4, a pair drawing to trips has 2, and an overcard often counts for 3 (when you believe a top pair would be best). Be careful not to count 'tainted' outs — cards that complete your draw but give an opponent a stronger hand. For example, if you have an open-ended straight draw but the board is two-flushed, some of your straight outs may complete an opponent's flush. The cleaner your out count, the more accurate the equity calculation.
What is the difference between pot odds and implied odds?
Pot odds are purely mathematical: the ratio of the current bet to the current pot, reflecting immediate profitability. Implied odds factor in additional money you expect to win from your opponent 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. However, implied odds are subjective and depend on your read of your opponent's tendencies. Estimate them conservatively — overstating implied odds to justify a call is one of the most common leaks in losing players' games. Reverse-implied odds (money you may lose on future streets when hitting your draw but still being beaten) should also be considered for hands like weak flush draws on paired boards.
When should I fold even if I have enough outs to call?
Fold when your implied odds are negative — for example, when hitting your draw creates an obvious board texture (third flush card on the river) that scares opponents into checking back rather than paying off. Fold when 'outs' are tainted: a straight draw on a heavy flush board may have 2–3 outs that complete an opponent's flush. Tournament ICM considerations can make mathematically neutral or even slightly +EV calls incorrect because the chip equity lost on a miss far outweighs the equity gained. Position matters — calling out of position reduces your ability to control pot size after hitting. Finally, against very tight opponents whose bet sizing always represents a strong made hand, your draw's equity may be lower than the formula suggests because they are unlikely to be bluffing.
What are common mistakes when applying pot odds in real time?
Forgetting to add the opponent's bet to the pot when computing pot odds (using potSize alone in the denominator instead of potSize + betSize) overstates the required equity. Counting tainted outs as clean inflates equity by 10–25%. Mixing up the rule of 2 (turn → river only) with the rule of 4 (flop → river) doubles or halves your equity estimate. Using the formula on the river when there are no more cards to come is meaningless — river decisions are pure pot-odds calls against an opponent's range, not draw math. Treating implied odds as guaranteed rather than probabilistic leads to chronic over-calling. Finally, ignoring the rake at low-stakes online sites overstates pot odds by 2–5%, since the actual pot you receive is reduced.
When should I NOT use this pot-odds calculator?
River decisions involve no draws — they are pure 'bluff catcher' equity calculations against your opponent's bet-betting range, not made-hand-vs-draw equity. Stack-off decisions in deep-stack games depend more on stack-to-pot ratio (SPR) and range vs range equity than on simple outs counting. Multi-way pots distort the calculation because outs that complete your hand may simultaneously help one of multiple opponents. Heads-up shove math near tournament bubbles uses ICM-adjusted equity, not chip-EV equity from this formula. Drawing hands that include implied blocker effects (e.g., draws that simultaneously block your opponent's natural calling hands) require a more nuanced range-vs-range solver. For complex spots use a true equity calculator like PokerStove, Equilab, or PioSolver instead of an outs-based approximation.
