Preflop

Your hand

Board

Opponent hand (optional)

Add the opponent's two cards to get clean outs against a real hand. Leave empty to count outs that improve your hand.

How the outs calculator works

01

Reads your real cards

It evaluates every unseen card as the next board card, so the out count comes from the actual hand, not a guess.

02

Drops tainted outs

When you name the opponent, a card only counts if it leaves you ahead at showdown, so dirty outs fall away on their own.

03

Prices the draw

It converts outs into exact hit odds, compares them to the rule of 2 and 4, and checks them against the pot you are facing.

Outs to percentage chart (1 to 20)

The numbers every drawing hand leans on. Turn means one card to come, river means two cards to come from the flop.

The full guide

Outs in poker: count them, clean them, and price the call

An out is any card left in the deck that turns your hand into the winner. Counting outs is the first real math skill in poker, and as of 2026 it is still the fastest way to know whether a draw is worth a chip. This guide shows how the calculator counts for you, why some outs lie to you, and how to turn the number into a call.

What an out actually is

You have a flush draw on the flop with two spades in your hand and two on the board. Nine spades are left in the deck. Each one completes your flush, so you have nine outs. That is the whole idea: count the cards that finish the hand you are chasing.

The catch is that outs are not always clean. A spade that pairs the board can hand your opponent a full house while it gives you a flush. That card looks like an out but it loses the pot. The calculator handles this for you the moment you enter the opponent's cards.

I counted outs by hand for years before I trusted a tool. The habit I never dropped: name the worst hand the opponent can have, then subtract the cards that beat me even when I hit. That single step turns a loose call into a good one.

Why outs matter more than a gut read

Outs are the bridge between your cards and a decision. They translate directly into how often you hit, and that number is the only honest way to compare the price you are paying to the reward you are chasing.

They give you a real percentage

Nine outs on the flop is about a 35% chance to make the flush by the river. That is a number you can act on, not a feeling.

They expose bad prices

If the pot is laying you 2 to 1 but your draw needs 3 to 1, the call burns chips over time. Outs make that leak visible.

They scale to every street

The same count answers two questions: hit on the very next card, and hit by the river. One number, two prices.

They train your instincts

Count outs enough times and you stop needing the calculator at the table. The tool is the trainer, not the crutch.

How the rule of 2 and 4 works

Multiply your outs by 2 to estimate your chance of hitting on the next card. Multiply by 4 to estimate your chance of hitting across the turn and the river together from the flop.

Nine outs times 4 is 36%, and the exact figure is about 35%. Close enough for a quick decision. The shortcut drifts high once you pass 8 outs, so for a big draw subtract a point or two from the times-4 number.

The calculator shows the rule estimate and the exact figure side by side, so you can see the gap instead of trusting the shortcut blind.

How to use this tool on ToolsGambling

The free outs calculator on toolsgambling.com is built to be used hand by hand. Here is the flow that gets the most out of it.

  1. 01

    Enter your hand and the flop

    Click the slots and pick your two cards and the three flop cards. The out map fills in instantly.

  2. 02

    Read the highlighted outs

    Green cards on the map are your outs, grouped by what they make. The count is your raw out total.

  3. 03

    Name the opponent

    Add the two cards you most fear. Tainted outs turn red and drop out of the clean count.

  4. 04

    Check the true equity

    The equity panel runs the exact showdown, so you see the real number behind the shortcut.

  5. 05

    Price the call

    Enter the pot and the bet. The verdict tells you whether the price beats your odds.

Common mistakes the calculator fixes

Most out-counting errors come from the same handful of habits. Each one quietly costs money.

Counting dirty outs as clean

A straight card that also completes a flush for your opponent is not an out. Naming the opponent removes it automatically.

Trusting times 4 on big draws

With 15 outs, times 4 says 60% but the real figure is closer to 54%. The exact column keeps you honest.

Forgetting you only have one card to come

Facing a turn bet, you only see the river. Use the times-2 number, not times 4, or you will overpay.

Counting outs that pair the board

A card that pairs the board can give a set or a full house. The tool checks the full showdown, not just your side.

Ignoring the price

A great draw at a bad price is still a fold. Outs only matter next to the pot odds.

Counting overcards as full outs

Two overcards are six outs in theory, but rarely six clean ones. Against a made pair, treat them as discounted.

Counting your outs step by step

Here is the routine that turns a hand into a number. It takes ten seconds once it is a habit.

  1. 01

    Name the hand you are chasing

    Decide what beats the opponent. A flush, a straight, top pair. You count outs toward that hand, not toward any improvement.

  2. 02

    Count the cards that complete it

    A flush draw has nine cards of your suit left. An open-ended straight has eight. A gutshot has four. Add overlapping draws once, never twice.

  3. 03

    Subtract the dirty ones

    Drop any card that also pairs the board into a likely full house, or completes a bigger flush for the opponent. Those are not your outs. This tool does it for you when you enter the opponent.

  4. 04

    Turn the count into a price

    Multiply by two or four for a quick read, or use the exact column, then compare it to the pot odds you are being offered.

The 13-plus outs correction

The rule of four reads high once you pass eight outs, because it double-counts the overlap between the turn and the river. For big draws there is a tidy fix.

Use (Outs times 4) minus (Outs minus 8). With 15 outs that is 60 minus 7, so 53 percent, and the exact figure is 54.1 percent. Close enough to act on, and far better than a raw 60. Under nine outs the plain rule of four is already accurate, so the correction only matters for monsters.

Outs to percentage at a glance

The shapes worth memorizing, two cards to come: four outs hit about 17 percent, eight outs about 32 percent, nine outs about 35 percent, twelve outs about 45 percent, fifteen outs about 54 percent. One card to come is roughly half of each. The full one-to-twenty chart above has the exact numbers.

Backdoor and runner-runner draws

A backdoor draw needs both the turn and the river to complete, like holding three to a flush on the flop. On its own it is worth roughly one and a half clean outs, so a backdoor flush plus a backdoor straight is about three.

This calculator counts single-card outs, the cards that win on the very next street. Backdoor equity lives in the true-equity panel, which runs the full board to the river, so a hand with extra runner-runner outs will show a slightly higher equity than its one-card out count alone suggests.

Outs in a multiway pot

Against two or three opponents your outs do not change, but their value drops. More players means more of your outs are dirty, because someone is more likely to hold the cards that beat you when you hit. A flush draw that is gold heads-up can be a trap five-handed. When you do not know the hands, leave the opponent empty and read the equity-versus-random number, then shade it down for every extra player in the pot.

Dead outs and tainted outs

A dead out is a card that is already gone, in a folded hand or burned, so it can never come. You cannot see those, so you do not subtract them. A tainted out is different: it is live, but it also hands the opponent a better hand, so it does not win. Tainted outs are the ones this tool removes once you name the opponent, which is why a raw count of twelve can become a clean count of nine.

Outs calculator FAQ

An out is any card still in the deck that turns your hand into the winning hand. Count them and you know how often you improve.
It deals every unseen card as the next board card and checks whether your hand improves. The cards that help are your outs, highlighted on the map.
A tainted out improves your hand but improves your opponent's hand even more, so you still lose. Enter the opponent's cards and the tool drops these automatically.
It is within a point or two up to about 8 outs. Past that it reads high, so for big draws lean on the exact column instead.
Nine. There are 13 cards of each suit, you can see four of them, so nine remain to complete the flush.
Eight. Four cards on each end complete the straight, which is why it hits more often than a gutshot.
No. Without them the tool counts every card that improves your hand. Add them to get clean outs against a real holding.
It compares your hit odds to the price the pot is laying you. If your equity beats the equity you need, it is a call.
Times 4 ignores the times you miss your draw but still win with a pair, and it overcounts big draws. The equity panel runs the real showdown.
