What counts as an out?

An out is any remaining card that improves your hand — turns no pair into a pair, a pair into two pair, a draw into a made flush or straight, and so on. This calculator counts every card that improves your own hand, not whether that improvement is enough to beat a specific opponent.

How accurate is the rule of 2 and 4?

It is a quick approximation, not the exact figure: multiply your outs by 4 on the flop (two cards to come) or by 2 on the turn (one card to come). It runs a little high once you are past about eight outs, which is why this calculator also shows the exact combinatorial odds alongside it.

How to use this calculator

Pick your two hole cards, then a 3-card flop or 4-card turn board. The calculator counts every unseen card that promotes your hand into a new, better kind of hand (not just kicker improvements within the hand you already have), and reports the exact odds to hit one on the next card and, on the flop, by the river — alongside the quick rule-of-2-and-4 estimate players use at the table.

Worked examples

Example 1
A flopped full house has one out left: the case card
nine of hearts, nine of diamonds on nine of clubs, two of spades, two of diamonds: nines full of twos is already made, so the only card that improves it is the last 9, for quads. That is 1 out out of 47 unseen cards — a reminder that “more outs” isn’t always better once you already hold a monster.
Example 2
A flush draw with two overcards has more outs than the flush alone
nine of hearts, eight of hearts on ace of hearts, king of hearts, four of spades: nine hearts complete the flush, and pairing the ace, king, nine, eight, or four also promotes high card into a pair. Counted together that is 23 outs to a better hand class, well above the 9 “pure flush outs” figure most players keep in their head — this calculator counts every way the hand improves, not just the headline draw.
