poker win rate calculator

Estimate your bb/100, profit, hourly rate, and a rough 95% confidence interval.

Total Hands Played Enter the size of your sample (e.g., 25,000 hands).

Net Big Blinds Won (or Lost) Use a negative number if you are down.

Big Blind Size ($) For $0.25/$0.50, enter 0.50.

Hours Played (Optional, for hourly rate)

Std Dev (bb/100, Optional) Typical cash-game ranges are often around 60-120 bb/100 depending on style and format.

What is poker win rate?

Your poker win rate is a measurement of how much you win, on average, over a fixed number of hands. In cash games, the most common format is big blinds per 100 hands (bb/100). This standardizes results and makes it easier to compare performance across stakes.

Example: if you win 500 big blinds over 10,000 hands, your win rate is: (500 / 10,000) × 100 = 5 bb/100.

How this calculator works

This tool computes the most useful practical metrics for poker tracking:

Win rate (bb/100): core long-term performance metric.
Total profit ($): converts big blinds into real money.
Hourly rate: useful for planning and game selection.
Hands per hour: pace and volume insight.
95% confidence interval: a rough range for your true win rate based on variance.

Formula summary

bb/100 = (Net BB won ÷ Hands played) × 100
Profit ($) = Net BB won × Big blind size
Hourly ($/hr) = Profit ($) ÷ Hours played
95% CI ≈ Win rate ± 1.96 × (Std Dev ÷ √(Hands/100))

Important: a short-term win rate can be very misleading. Poker has high variance, and even strong players can run below expectation for long stretches. Use larger samples whenever possible.

How many hands do you need for a reliable win rate?

There is no perfect cutoff, but as a rule of thumb, reliability improves as sample size grows. Many players use these rough checkpoints:

Under 20,000 hands: highly noisy, mostly directional.
20,000-100,000 hands: better, but still swingy.
100,000+ hands: much more informative for most cash formats.

The confidence interval in the calculator helps show this. If your interval is very wide, you likely need more volume before drawing strong conclusions.

Practical interpretation of your result

Positive win rate

If your bb/100 is positive, you are currently beating the game in your sample. Next step: keep improving and protect your edge with strong table selection and tilt control.

Near break-even

A small win rate (around -1 to +2 bb/100) can still be okay depending on rake, game quality, and sample size. Before changing everything, check leaks by position, preflop spots, and river decision quality.

Negative win rate

A negative number does not mean you cannot win long-term, but it does signal a need for review. Focus first on big recurring leaks: overcalling, poor blind defense, weak c-bet strategy, and emotional decision-making.

Ways to improve your poker win rate

Play in softer games and better seat positions.
Track by position (UTG, CO, BTN, blinds) and identify losing nodes.
Study high-frequency spots: 3-bet pots, turn barrels, blind vs blind.
Reduce autopilot by using shorter, focused sessions.
Review marked hands weekly and create one clear adjustment at a time.
Manage bankroll to avoid playing scared or under-rolled.

Cash games vs tournaments

This calculator is optimized for cash-game bb/100 tracking. Tournament players usually evaluate performance using ROI, average buy-in, and chip EV (or bb/100 by phase, if tracked).

Final thoughts

A poker win rate calculator is best used as a decision aid, not a final verdict on your skill. Combine data with hand reviews, coaching feedback, and mental game work. Over time, small strategic improvements can compound into a large edge.
