Pot odds calculator
The price of a call, as a number. Enter the pot and the bet you face; get the pot odds, the equity you need to break even, and — if you have an estimate — the expected value of calling.
The spot

What the math says
With 35% equity, calling is profitable in expectation.
Expected over many repetitions of this exact spot, assuming the call closes the action. Future streets, implied odds and reverse implied odds are not included.
Break-even equity by bet size
Facing a bet of this size, you need at least this much equity to call.
| Bet | Pot odds | Break-even | Bluff must work |
|---|---|---|---|
| ¼ pot | 5 : 1 | 16.7% | 20.0% |
| ⅓ pot | 4 : 1 | 20.0% | 25.0% |
| ½ pot | 3 : 1 | 25.0% | 33.3% |
| ⅔ pot | 2.5 : 1 | 28.6% | 40.0% |
| ¾ pot | 2.3 : 1 | 30.0% | 42.9% |
| Pot | 2 : 1 | 33.3% | 50.0% |
| 1½× pot | 1.7 : 1 | 37.5% | 60.0% |
| 2× pot | 1.5 : 1 | 40.0% | 66.7% |
“Bluff must work” is the same formula from the bettor’s side: how often a bet with no equity must win the pot outright to break even.
Pot odds in one sentence
Pot odds compare what you can win with what you must risk. Facing a $50 bet into a $100 pot, you risk $50 to win $150: pot odds of 3 : 1. You break even if you win the pot at least 1 time in 4 — 25% equity.
The break-even formula is call ÷ (pot + bet + call). Memorise a few sizes and you will never need the calculator at the table: a half-pot bet needs 25%, a pot-sized bet needs 33%, a two-thirds bet needs 28.6%.
What this number leaves out
Pot odds assume the hand ends now. When there are more streets to come, money you might win later (implied odds) or lose later (reverse implied odds) changes the real price. The calculator is honest about this: it never adds assumptions you did not give it.
For the future-money question, use the implied odds calculator. Turn a draw into an equity estimate with the draw odds explorer, then practise the whole decision under the clock in the trainer.
