Odds to Probability Calculator: Convert Bookmakers’ Odds and Calculate RTP

Are you looking to transform bookmakers’ odds into probabilities and calculate the total scaled probabilities of an event? This Odds to Probability Calculator is a handy tool that simplifies this process for you. Not only does it convert odds to probabilities, but it also calculates the Return to Player (RTP) percentage, giving you a comprehensive view of your betting decisions.

Key Features:

  1. Odds to Probability Conversion: With our calculator, you can input the decimal odds provided by bookmakers. It instantly converts these odds into probabilities, helping you understand the likelihood of an event occurring.

  2. Scaled Probabilities: Ever wondered how each set of odds contributes to the overall outcome? Our tool calculates the scaled probabilities for each set of odds in relation to the total, presenting them in an easy-to-understand percentage format. For instance, if you have two odds, such as 1.5 and 2.0, our calculator will show you that they correspond to 57.14% and 42.86% of the total, respectively.

  3. Total RTP Calculation: The Return to Player (RTP) is a crucial metric for bettors. Our calculator computes the total RTP by considering the sum of all bookmaker-implied probabilities and subtracting it from 100%.
