About EV Calculator
This educational tool demonstrates expected value calculations for theoretical betting scenarios. Designed to teach mathematical decision-making concepts without any connection to real gambling activities or financial advice.

How It Works

1. Input probability of winning (0-100%)
2. Enter potential payout amount
3. Add theoretical stake amount
4. Calculates long-term expected value
5. Shows profit/loss assessment

Legal Disclaimer
By using this calculator, you agree:

1. Purely academic/entertainment purpose
2. No real-money gambling association
3. Prohibited for financial decisions
4. Users must be 18+ years old
5. Does NOT predict actual outcomes
6. We oppose all gambling activities
7. Results are mathematical models
8. Compliance with all gaming laws

Calculation Methodology
Core Formula:
EV = (Win% × Payout) - (Lose% × Stake)

Where:

• Win% = Input Probability ÷ 100
• Lose% = 1 - Win%

Educational Value

• Teaches expected value concepts
• Demonstrates risk/reward analysis
• Shows probability-weighted outcomes
• Illustrates long-term thinking
• Explains mathematical advantage

Strict Prohibitions
ANY association with:

• Real-money gambling
• Investment decisions
• Betting strategy development
• Underage usage
• Financial planning

Technical Specifications

• Handles decimal inputs
• Validates probability range
• Mobile-responsive design
• Instant calculations
• No data retention

Analysis Limits

• Ignores variance (short-term swings)
• Static probability assumption
• No compounding effects
• Single-event focus
• Simplified binary outcomes

Mathematical Guide:

• Positive EV (+): Long-term profitable
• Negative EV (-): Long-term losing
• Break-even (0): No mathematical edge

Example Calculation:
50% Win Chance | 200Payout∣200Payout∣100 Stake
EV = (0.5×200) - (0.5×100) = 50Interpretation:+50Interpretation:+50 expected value per trial

Key Assumptions:

• Independent identical events
• Accurate probability estimates
• Fixed payout/stake amounts
• No transaction costs
• Infinite trials
