About This Template
Calculate your mathematically optimal bet size or portfolio allocation with this professional Kelly Criterion Excel template. Whether you're sizing sports bets, poker stakes, or investment positions, this spreadsheet gives you the exact Kelly fraction to maximize long-term wealth growth.
What You Can Calculate
This template computes five key outputs from your inputs:
- Full Kelly Fraction - The mathematically optimal percentage of your bankroll to wager or invest
- Half Kelly & Quarter Kelly - Conservative alternatives that reduce volatility while preserving most expected growth
- Dollar Amount - Your optimal stake size based on your total bankroll
- Expected Growth Rate - The expected log-growth per bet (discrete) or excess growth over cash (continuous)
- Kelly Classification - Qualitative assessment: No Edge, Conservative, Moderate, Aggressive, or Leveraged
Required Inputs
The template supports two modes via a dropdown selector:
- Discrete Mode (Gambling): Win Probability (1-99%) and Win/Loss Ratio (odds)
- Continuous Mode (Investments): Expected Return, Risk-Free Rate, and Volatility
- Both modes: Bankroll/Portfolio size for dollar calculations
Methodology
The template implements the classic Kelly Criterion formulas: f* = p - q/b for discrete bets and f* = (ฮผ - r) / ฯยฒ for continuous investments. All formulas are visible and editable so you can verify the math or extend the model.
Assumptions & Limitations
- True probabilities and expected returns are known with certainty
- Independent trials with constant parameters
- Fractional betting allowed, no transaction costs
