Calculate Losing Streak Probability
What is the Losing Streak Calculator?
The Losing Streak Calculator helps you understand the probability of experiencing consecutive losses when gambling at specific odds. It answers questions like "How likely am I to lose 10 times in a row at 2x odds?" or "Once in how many rolls will I experience a 15-game losing streak?"
The Mathematics
Win Probability: (1 / odds) × (1 - house edge / 100)
Loss Probability per Bet: 1 - Win Probability
Streak Probability: (Loss Probability)Streak Length
Expected Frequency: 1 / Streak Probability
Example: At 2x odds with 1% house edge (49.5% win rate), losing 10 times in a row has a probability of (0.505)10 = 0.127% or once in 787 rolls.
Understanding Your Results
🎯 What Does This Mean?
If a losing streak has a probability of 0.1% (once in 1,000 rolls), it means that on average, you'll experience this streak once every 1,000 bets. However, this doesn't mean it will happen exactly every 1,000 bets - it could happen sooner or later due to randomness.
⚠️ Bankroll Management
Understanding losing streaks is crucial for bankroll management. Your bankroll should be large enough to survive expected losing streaks at your stake level. Use the Bankroll Management Calculator to determine appropriate bet sizes.
📊 Likelihood Ratings
- Very Common: Will happen frequently (>1%)
- Common: Expect to see regularly (0.1% - 1%)
- Uncommon: Occasional occurrence (0.01% - 0.1%)
- Rare: Infrequent (0.001% - 0.01%)
- Very Rare: Extremely unlikely (<0.001%)
🔄 The Gambler's Fallacy
Remember: Each bet is independent. If you've lost 9 times in a row, your chance of losing the 10th bet is the SAME as it was for the first bet. Past results do not influence future outcomes in games of chance.
Practical Use Cases
