By-river values track hitting at least one of the original outs, with 47 unseen cards and two draws. Further improvements can also arrive through two-card combinations.

How to Calculate Pot Odds

Pot odds compare the pot you can win with the chips needed to call. Enter the pot as it stood before the opponent’s bet. The tool adds that bet to get your immediate reward, then adds your call to get the final pot.

For the initial example, the pot is 100 and the opponent bets 50. You can win the existing 150 by calling 50. That price is 3:1, and the final pot is 200. Your break-even equity is 50 / 200, or 25%.

The formula is call / (pot before bet + bet + call). When the bet equals your call, it becomes bet / (pot + 2 × bet). The ratio and percentage express the same price in different ways.

At that equity, wins and losses balance over repeated identical calls when all remaining cards are dealt and the pot has no deductions. More equity gives a positive expectation under those conditions. Future bets, rake and different pot eligibility change the decision.

Already facing several contributions?

Enter the amount you need to call in the bet field. Enter all chips now in the middle minus that call amount in the pot field. The tool then uses the full pot available to your call. With unequal all-in stacks, compare each eligible pot separately.

Outs, hit chance and equity

An out is a remaining card that makes the improvement you are counting. The flush example has four hearts among the five visible cards. Counting the remaining hearts gives its outs. The straight examples count ranks that complete the sequence, including every available suit.

From the flop, there are 47 unseen cards when you know only your two hole cards and three board cards. On the turn there are 46. The next-card formula is outs / unseen. With two draws, the chance is one minus the chance of missing on both: 1 − (47 − outs) × (46 − outs) / (47 × 46).

Those formulas keep the original out set fixed. A backdoor draw needs two useful cards in sequence; a new turn card can also create fresh outs. Known opponent cards remove cards from the remaining deck.

A completed draw may still lose to a stronger hand, and a river card can overtake a turn improvement. Use the equity calculator with exact opposing hands for your full showdown equity. Its next-card outs count only cards that put Hero alone ahead against those opponents.

Pot Odds for Common Bet Sizes

When you face a single bet with no previous contribution to match, the bet size also gives the amount to call. Each row starts with the same pot before the bet, adds the opponent’s bet and your call, then divides your call by that final pot.

Bet / pot before betPot oddsBreak-even equity
1/3 pot4.00:120.00%
1/2 pot3.00:125.00%
2/3 pot2.50:128.57%
1× pot2.00:133.33%
2× pot1.50:140.00%

A larger bet asks you to risk more chips relative to the pot already available. That raises the equity needed to break even. The percentage stays the same when every chip amount scales together, so a fraction-of-pot table works for either tournament chips or cash-game units.

Use the threshold to price a call when that call takes you to showdown without further betting, such as calling an all-in. With further betting possible, a flop call buys the next card and the right to make another decision. Future calls can add to the cost of reaching showdown.

The Rule of 2 and 4 Compared with Exact Chances

For a quick estimate, multiply the out count by two with a single card to come, or by four with both turn and river to come. The table compares those shortcuts with the exact chance of hitting at least one original out. Percentages are rounded to the nearest hundredth.

The single-card column starts on the turn, with your hole cards and the board known. The two-card column starts on the flop. As outs increase, hitting one on the turn and another on the river becomes more common. Counting the chance of at least one hit accounts for that overlap; multiplying outs by four remains an approximation.

Use the rule of four when the price covers both remaining cards. If you will face a new bet on the turn, compare the current price with the next-card chance and consider that later decision separately. Keep the difference between completing a draw and winning the pot in view: a flush can complete while also pairing the board for an opponent’s full house.
