Find out how much equity you need to call a bet and whether calling is profitable in your example, step by step.
Fill in the six steps below to see whether the price of a call matches your chance of winning; each step explains its result. If you already know your equity, use the advanced mode.
How it works: a step-by-step example
- Step 1Imagine the pot has 100 chips and your opponent bets 50 chips.
- Step 2To stay in the hand you must pay 50 chips: that is the cost to call.
- Step 3If you call, the final pot will be 100 chips + 50 chips + 50 chips = 200 chips.
- Step 4Required equity = call cost ÷ final pot = 50 chips ÷ 200 chips = 25.0%.
Required equity25.0%
That 25.0% is the minimum equity to call without losing chips on average: your hand has to win at least one in every 4 times this spot is repeated.
Now estimate your chance. You hold a flush draw: 9 hearts are still unseen. If each one gives you the best hand, you have 9 clean outs.

- Only the turn guaranteed: 9/47 ≈ 19.1% (rule of 2: 18.0%). It is below 25.0%, but that is not an automatic fold: more betting can follow.
- Turn and river guaranteed (your call closes the betting): 378/1081 ≈ 35.0% (rule of 4: 36.0%). It is above 25.0%:CALL — Profitable in this example
Hitting your draw is not the same as having that much equity: an out can still lose if the opponent has something better. These results hold for this example and count chips only; a real tournament can change the decision.

Hitting is not the same as having that much equity: an out can still lose if the opponent has something better, and sometimes you win without hitting. The calculation treats your chance of hitting as your equity only if every out is clean.
