Kelly Criterion Calculator

Understand the kelly criterion calculator result

Kelly Criterion Calculator gives a focused calculation for studying bankroll theory with an independently estimated probability and payoff ratio. It asks for win probability percent, net decimal odds and reports kelly fraction percent. Full Kelly fraction equals net odds times win probability minus loss probability, divided by net odds. A 55 percent chance at even-money net odds gives a full-Kelly fraction of about ten percent. By exposing kelly fraction percent, Kelly Criterion Calculator makes this specific arithmetic inspectable instead of presenting an unexplained number.

With the page defaults of Win probability percent 55, Net decimal odds 1, the verified output is Kelly fraction percent 10. Negative results indicate no positive theoretical stake rather than a requirement to bet against the event. In Kelly Criterion Calculator, each labeled default remains visible while you edit, so you can change one assumption at a time and trace how kelly fraction percent responds.

Method, limits, and private processing

Probability estimates are uncertain, outcomes may be correlated, and full Kelly can create severe drawdowns. Kelly Criterion Calculator evaluates the entered values entirely in your browser, without sending the inputs to a server. When using its kelly fraction percent, retain the stated method and input units because this result is bounded by the assumptions of full Kelly fraction equals net odds times win probability minus loss probability, divided by net odds.
