Example of Using Kelly Criterion Formula
Let us take particular attention to a football game: Manchester United against Liverpool. You think Manchester United has a 55% chance of winning the game (p=0.55). The bookmaker gives Manchester United winning odds of 2.2.
To calculate the optimal bet size using the Kelly Criterion formula:
| Determine the variables |
|---|
| p=0.55p = 0.55p=0.55 (probability of Manchester United winning) q=0.45q = 0.45q=0.45 (probability of losing, which is 1−p1 – p1−p) b=1.2b = 1.2b=1.2 (odds minus 1; here, 2.2−1=1.22.2 – 1 = 1.22.2−1=1.2) |
| Apply the Kelly Criterion formula |
|---|
| f∗=bp−qb=1.2×0.55−0.451.2=0.66−0.451.2=0.211.2≈0.175f^* = \frac{bp – q}{b} = \frac{1.2 \times 0.55 – 0.45}{1.2} = \frac{0.66 – 0.45}{1.2} = \frac{0.21}{1.2} \approx 0.175f∗=bbp−q=1.21.2×0.55−0.45=1.20.66−0.45=1.20.21≈0.175 |
Based on the Kelly Criteria, Manchester United winning this game should cause about 17.5% of your bankroll to be risked. This deliberate participation is meant to maximize long-term development under control of risk.
