Run the numbers. No account. Choose a free poker calculator for cash-game results, tournament ROI, bankroll or variance. Each explains its formula and assumptions. Browse all tools, including card equity, ranges and ICM.
Cash-game variance
Explore result paths under fixed win-rate and standard-deviation assumptions.
Tournament results
Calculate ROI from total buy-ins and cashes.
Tournament variance explained: tournament payouts need a different model from cash-game results.
Poker bankroll calculator
A bankroll is measured in buy-ins, not cash. The more your results swing (standard deviation) and the thinner your edge (win rate), the more buy-ins you need to ride out variance without going broke. The formula is bankroll in big blinds equals minus S squared times the natural log of your target risk, divided by twice your win rate.
Open →Poker hourly rate and BB per hour calculator
Your hourly rate is profit divided by hours, the number poker actually pays you in the seat. Convert it to BB/hr to compare across stakes, and project it at your weekly volume.
Open →Poker variance calculator
Even a fixed edge produces many plausible bankroll paths. The simulator makes those paths, bands and bankroll consequences visible without pretending the model can judge your play.
Open →Poker downswing calculator
A positive-edge Brownian model gives a characteristic drawdown scale from volatility squared divided by twice the edge. It does not predict a maximum downswing.
Open →Poker risk of ruin calculator
Risk of ruin is the probability of busting your roll before your long-run edge takes over. It falls fast as you add buy-ins or raise your win rate.
Open →Tournament ROI calculator
ROI is profit as a percentage of everything you bought in for, the headline win-rate metric for tournaments, where hourly is noisy.
Open →Poker EV calculator
Expected value is what a decision is worth on average if repeated forever. For a river call it weighs the pot you win against the bet you lose, by your equity.
Open →Poker stop-loss calculator
A stop-loss caps a session loss to protect you from tilt and fatigue leaks, not just chips. Set it in buy-ins so it scales with your stake.
Open →Win-rate confidence calculator
A win rate only means something next to the hours behind it. This shows the 95% band around your figure and whether the whole band sits above break-even.
Open →Move-up readiness calculator
Moving up needs two gates: enough buy-ins at the new stake, and a proven win rate at the one you are leaving. This sizes the first gate, so you take a shot on the maths rather than on a hot streak.
