How to Use the Kelly Criterion Calculator

Developed by John L. Kelly Jr., it uses the probability of a positive return and the win/loss ratio to suggest precise investment amounts. It’s the subject of much debate, but the answer to this is that stakes should be calculated according to the Kelly Criterion. Because the Kelly Criterion seeks to calculate the optimum stake for any value bet so as to maximise that value as well as maximise the growth of your betting bankroll. In other words, the Kelly Criterion takes into account both the size of your advantage (I.e the value available) and the size of your bankroll, so as to minimise risk and maximise your advantage. One is a rebounding prop that wins 60% of the time and the vig is +100, giving it a 20% ROI.

If you repeatedly bet too much (over 20%) on a low number appearing, there’s a good chance you’ll eventually go broke. Conversely, under-betting (less than 20%) should produce a more modest profit. Note that the content on this site should not be considered betting advice. In addition, the odds in poker can change from one hand to another, depending on the cards and how players bet. And because the Kelly Criterion relies on fixed odds and clear probabilities, it doesn’t fit well with the unpredictability of poker.

The formula balances the potential for growth against the risk of loss, helping you find the sweet spot between betting too much (increasing risk of ruin) and too little (missing growth opportunities). This flexibility makes the Kelly Criterion a valuable tool for managing investments in various scenarios, ensuring that position sizes are optimized for both risk and return. Applying the formula to various scenarios helps investors and gamblers find the best strategy for maximizing returns while managing risk.

See what happens to each curve as you change the probability of heads, first to 50%, and then to below 50%. The plot below shows the median return for different values of ℓ\ellℓ. The optimal strategy is to bet the value of ℓ\ellℓ that maximizes the median return, shown as a dot. The Kelly Criterion does not guarantee winning stock picks or predictions of market crashes. Investors should be aware of these risks and use the Kelly Criterion as a guide, not a foolproof solution.

By understanding its mathematical foundations, practical applications, and key principles, investors can use the Kelly Criterion to manage risk and maximize long-term returns. The case study and practical examples provided illustrate how the Kelly Criterion can be applied in real-world scenarios, highlighting its effectiveness in various investment contexts.

There can be many reasons why you fail, such as not being able to define the true probability of an outcome accurately.

Depending on the value of the odds, the bet size can differ, hence the emergence of Kelly calculators. You can also use a regular calculator if you learn how the formula works, which we explain next. The Kelly Criterion is a formula for calculating the optimum bet size relative to your bankroll and the implied odds and actual (true) odds. In other words, the formula can help you determine the optimal amount of money (bet size) you should risk (invest) relative to the true odds and implied odds of winning.

As you can see, there’s no strategy (lever) which beats every other strategy more often than not for a single draw. The tables below show the nine equally-probable outcomes of a draw each pair of these three random variables. If we have a means of saying that one strategy is better than another, we can define a best strategy as one for which no other strategy is better. Typically, when a dice is thrown, the chance of it landing on a 1, 2, or 3 is 50%, while the same percentage applies to an outcome of 4, 5, or 6. Yes, beginners can use the Kelly Criterion, but starting with more conservative variations, like the Half or Quarter Kelly, is recommended to reduce risks while learning.

In my Sep. 20, 2007 Ask the Wizard column I suggested the Kelly bettor should sometimes not play optimal video poker strategy. Speaking of investors, instead of Kelly’s “gain”, they say rate of return,and instead of a single coin flip or die roll, they typically speak of anasset’s performance over a single year. The remaining term approaches \(\log X\), thus we wind uplosing everything except for what we cannot gamble.Either way, log wealth teaches us going all in is a bad strategy.

The Kelly calculator is one of our most popular bet calculators, because it makes a complex mathematical equation easy to understand.
