What Is Kelly Criterion?

The Kelly Criterion is a strategy for determining theal bet size in relation to your bankroll and perceived edge. Once you understand each wager's anticipated winning per cent, you may utilise this betting strategy to make informed sports betting decisions.

The underlying mathematical formula is: x = (yp – q) / y; where x is the fraction of your bankroll you should bet, y is the bookmaker back odds (in decimal), p is the probability of winning (edge), and q is the probability of losing.

The fractional Kelly betting option allows you to adjust your betting strategy depending on how aggressive or conservative you want (1 being the standard and 0 being the highest conservative setting). Finally, after adjusting your estimated probability while using the Kelly criterion calculator, expect your profit and betting account balance to improve over time.

Below, we will dive into how to use the Kelly criterion when you place bets.

Current Betting Balance

The Kelly criterion helps you determine how much money you can risk while placing your bets. Multiply this value by the current betting account balance you enter in the Kelly criterion calculator to get a recommended optimal bet stake.

Fractional Kelly Betting

This value will be multiplied by the Kelly criterion stake that has been proposed. Adjust the fractional Kelly betting value to 1.00 for conventional Kelly betting. Enter a value smaller than 1 if you want to be more conservative than the Kelly criterion.

Your Win Probability

This is the projected probability of the selection winning. The Kelly criterion uses this value to determine the optimal bet stake to recommend. It must be a number between 0 and 1. For example, input 0.5 if you believe the selection has a 50 per cent chance of winning.

Bookmaker Back Odds

It takes a more deliberate approach to gambling and leaves very little to chance. However, figuring it all out on your own might be difficult. This can eat up a lot of your time, time that could be better spent making informed wagers and finding the best odds offered.
