Kelly Criterion in Football Betting for Beginners

The Kelly Criterion is a formula considered highly significant in financial investment and betting. In football betting, this formula is used by bettors to significantly enhance their investment performance over time. In this article by win betting tips, we'll provide detailed information about this unique betting formula. Let's dive right in.

An Overview of the Kelly Method

The Kelly Criterion is a formula devised to calculate the betting odds of an event, determining the risk level for each specific bet. There are several variations of the Kelly Criterion, and the simplest formula is: (B x P - Q) / B. Where:

B represents the decimal odds.

P is the actual probability.

Q = 1 - P.

For instance, consider applying this formula to a match between Team A and Team B. If Team A's winning probability is 58.5% with decimal odds of 1.71 and Team B's winning probability is 27.4% with odds of 3.65, and the probability of a draw is 30.8% with odds of 3.25:

To calculate the percentage to bet if Team A wins with a probability of 65%, using the Kelly formula: P = 0.65; B = 1.71 - 1 = 0.71; Q = 1 - 0.65 = 0.35. Therefore: (0.71 x 0.65 - 0.35) / 0.71 = 15.7%.

The Kelly Criterion suggests that based on the provided betting odds and the assessed actual probability of 0.65, a bettor should wager 15.7% of their account balance. This percentage might seem high to some, but it's meant for those who understand this formula. Sometimes, the proposed percentage could reach 20% or 30%.

History of the Kelly Criterion

John Kelly, while working at Bell Labs for AT&T, initially developed the Kelly formula to assist AT&T in addressing issues related to signal-to-noise ratio in long-distance telephone lines. Soon after, this calculation method was introduced as "A New Interpretation of Information Rate" in 1956.

However, the gambling community recognized the potential of this formula in football betting. The formula allows players to maximize their bankroll over a longer period. That's why many still use it as a money management system for betting and investment.

Overview of the Kelly Criterion in Football Betting

In 1956, the Kelly formula was developed to ensure optimal growth of the betting fund. As mentioned earlier, it was initially created to assist AT&T and later expanded to other fields as an effective financial management approach.

This formula requires careful calculation, thorough analysis, and patient use over an extended period to yield effectiveness. Presently, the Kelly formula in football betting is expressed as: Bet Amount = ((Odds x % Chance of Winning) - 1) / (Odds - 1) x 100.

Pros and Cons of Using the Kelly Criterion in Betting

Here are the advantages and disadvantages of the Kelly formula:

Advantages:

Effective bankroll management before and during betting participation.

Carefully calculated and rational betting amounts based on the bookmaker in betting and loss probability.

Minimizes risks to maximize betting returns.

Provides an overall view of matches before deciding which team to bet on.

Simplifies statistical data analysis for an appropriate betting strategy.

Disadvantages:

The accuracy of money management using this formula cannot reach 100%.

Bettors need to determine the winning probability for the match they want to bet on.

How to Apply the Kelly Criterion in Betting

This money management formula is used across various game types and at different bookmakers. For example, in a match between Team C and Team D, with the following information:

Total betting amount: $100

Winning odds for Team A: 60%

Betting odds: 1.93

The Kelly formula for the bettor would be: Betting percentage = ((1.93 - 60%) - 1) / (1.93 - 1)) x 100 = 16.99%.

Note: If these percentages turn out negative, it could be due to a low winning probability for the match. In such cases, there are two options: bet on the opposing team or refrain from betting on that match.
