Free poker calculators
Every result on these pages comes from unit-tested functions in @poker/kernel, the engine behind what PokeAI labels Computed — exact arithmetic, or for preflop equity a fixed-seed simulation that says so. No sign-up, nothing stored, no estimates dressed up as answers.
- Pot Odds CalculatorWork out the exact equity a call needs. Enter the pot and the bet you face; the result comes from a deterministic engine, not an estimate.
- Call EV CalculatorEnter your equity, the pot and the bet to see the expected value of a call in chips, plus how much equity you are above or below break-even.
- MDF CalculatorCalculate minimum defence frequency against any bet size, plus the maximum you can fold and the bluff-to-value ratio that makes the bet indifferent.
- Fold Equity CalculatorHow often a bluff or semi-bluff has to work to break even. Enter what you risk, the pot you win when everyone folds and, for a draw, your equity when called.
- ICM CalculatorConvert tournament stacks into prize money with the Malmuth-Harville ICM model, and compare an ICM chop with a chip chop before agreeing a deal.
- Risk of Ruin CalculatorHow likely is your bankroll to bust at your ROI and variance, and how many buy-ins you need to bring that risk under 5% or 1%.
- Poker Bankroll CalculatorWork out how many buy-ins you need for cash games, sit & gos and tournaments from your win rate or ROI, your swings and the risk of ruin you accept.
- Poker Hourly Rate CalculatorTurn bb/100 into an hourly rate across tables and stakes, add rakeback, and see the range your true win rate could sit in after the hands you have played.
- Poker Equity CalculatorCalculate all-in poker equity for a hand or range against up to two opponents, before or after the flop. Exact after the flop, simulated before it.
The calculators are the easy half
Knowing you needed 33% is one thing. Knowing whether the way you play those spots is costing you money over a year of sessions is another — that takes your own tracked results. See how PokeAI uses them.
