Outs Calculator

Estimate your chance of hitting a winning hand based on the number of outs you have.


📉 Chance to hit by next card (Turn or River): 📈 Chance to hit by River (Turn + River):

About Outs Calculator
This educational tool demonstrates poker probability calculations using the “Rule of 2 and 4”. Designed for theoretical strategy discussions only, with no connection to real-money gambling or professional poker play.

How It Works

  • Input number of potential winning cards (outs)
  • Calculates approximate probabilities using:
    • Next Card: Outs × 2%
    • Two Cards: Outs × 4%
  • Shows simplified percentage estimates

Legal Disclaimer
By using this calculator, you agree:

  1. Purely educational/entertainment purpose
  2. No real-money poker association
  3. Prohibited for gambling decisions
  4. Users must be 21+ years old
  5. Does NOT guarantee poker success
  6. We oppose online gambling
  7. Results are approximations only
  8. Compliance with all gaming laws

Calculation Methodology
Rule of 2 and 4 Approximation:

  • Turn Probability: (Outs × 2)%
  • River Probability: (Outs × 4)%
    Note: Actual probabilities are slightly lower than these estimates

Educational Value

  • Teaches quick probability estimation
  • Demonstrates implied odds concepts
  • Shows equity calculation basics
  • Illustrates poker mathematics fundamentals

Strict Prohibitions
ANY association with:

  • Real-money poker decisions
  • Gambling strategy development
  • Tournament preparation
  • Underage usage
  • Financial risk analysis

Technical Specifications

  • Handles 1-47 outs input
  • Instant approximation
  • Mobile-friendly design
  • No data collection/storage

Analysis Limits

  • Ignores opponent’s potential outs
  • Doesn’t account for burned cards
  • Simplified rounding system
  • No community card analysis
  • Static probability model

Probability Guide:

  • 8 Outs = ~16% on Turn / ~32% by River
  • 15 Outs = ~30% on Turn / ~60% by River
  • Max 47 Outs = ~94% on Turn / Theoretical 188% (capped at 100%)

Mathematical Note:
True Formula = (Outs ÷ Remaining Cards) × 100
The “Rule of 2/4” provides quick approximations within 1-2% accuracy
