How do you calculate odds of winning?

All you need to do is apply the following formula.

  1. 1 / Odds. This will always give you a number between 0 and 1, which is technically the “correct” way to express probability.
  2. (1 / Odds) x 100. This formula will give you the implied probability of odds as a percentage.
  3. (1 / 3.00) x 100 = 33.33%
  4. (1 / 1.5) x 100 = 66.67%
