A simple guide to the Kelly Criterion calculator

Feeling a little overwhelmed about how the Kelly formula calculator works? Well, you don’t have to worry as we have you covered. In this section, we’ll explain in simple terms how this betting calculator works.

The Kelly betting calculator is a mathematical betting formula that will work out how much you should be wagering. Let’s say your total bankroll is $6,000, it’s common sense that you should stake the entire amount on one bet. Regardless of how great the odds are, even the best bets can lose, so you don’t want your risks to be too high. So, what’s your optimal bet size? Well, that’s where this calculator comes in.

Kelly Criterion is a betting strategy that helps you to work out the probability of a specific event happening when there is a difference between the true odds and those advertised by the sportsbooks. You will input the multiplier, odds, and win percentage, before being given the amount that you should wager on the specific event to maximize your profit.
