Poker Outs To Percent
A precise tool.
What is the Poker Outs To Percent & How does it work?
In Texas Hold’em, an “out” is any unseen card that will improve your hand to likely win. Counting outs accurately is the first step toward estimating your chance of winning a hand. The poker community often uses the “Rule of 2 and 4” as a quick mental shortcut. Multiply your outs by 2 when you have one card left to see (the turn) and by 4 when two cards remain (the river). This gives an approximate percentage chance of completing your hand. For a more precise calculation you can use the formula below, which accounts for the exact number of unseen cards. The result is then rounded to a convenient one‑decimal place for easy interpretation.
P = frac{text{outs} times text{multiplier}}{text{remaining;cards}} times 100
outs = number of outs, multiplier = 2 for turn or 4 for river, remaining cards = cards left to be dealt (47 after the flop, 46 after the turn)
