Poker math
Pot odds and required equity
Section 1 of 7Name each quantity
Pot odds are the price of calling: what you can win compared with what the call costs. To see them, start with the pot before the bet, add the opponent's bet (current pot) and add your call (final pot).
Formula
Required equity = call cost ÷ final pot
Example data
- Pot before the bet
- 10 BB
- Opponent's bet
- 5 BB
- Step 1Current pot (before your call)10 BB + 5 BB = 15 BB
- Step 2Call cost5 BB
- Step 3Final pot if you call15 BB + 5 BB = 20 BB
- Step 4Required equity5 BB ÷ 20 BB = 25%
Result
Required equity25%
- Pot odds
- 3 : 1
- Final pot if you call
- 20 BB
This is the minimum equity for calling to be profitable in the simplified chip-EV model. In a real tournament, future bets, stacks, ICM and bounties also matter.
15 BB : 5 BB = 3 : 1
1 ÷ (3 + 1) = 25%
