by

Understanding how to convert sports betting odds into implied probabilities is essential for bettors looking to evaluate their bets effectively. BigMikeSports.com provides a comprehensive guide to help you grasp this concept and make smarter betting decisions.

What Are Implied Probabilities?

Implied probability represents the likelihood of an event happening, as reflected by the betting odds. It helps bettors assess whether a bet offers good value compared to their own estimate of the event’s outcome.

Converting Odds to Implied Probabilities

The method of conversion depends on the type of odds provided: decimal, fractional, or American. BigMikeSports.com explains each method clearly.

Decimal Odds

To convert decimal odds to implied probability, use this formula:

Implied Probability = 1 / Decimal Odds

For example, if the decimal odds are 2.00, the implied probability is:

1 / 2.00 = 0.50 or 50%

Fractional Odds

To convert fractional odds to implied probability, use this formula:

Implied Probability = Denominator / (Numerator + Denominator)

For example, fractional odds of 3/1 translate to:

1 / (3 + 1) = 1 / 4 = 0.25 or 25%

American Odds

American odds differ for favorites and underdogs. The formulas are:

  • For positive odds (underdogs): Implied Probability = 100 / (Odds + 100)
  • For negative odds (favorites): Implied Probability = -Odds / (-Odds + 100)

Example: +150 odds:

100 / (150 + 100) = 100 / 250 = 0.40 or 40%

Example: -200 odds:

-(-200) / (-(-200) + 100) = 200 / (200 + 100) = 200 / 300 = 0.6667 or 66.67%

Why Use Implied Probabilities?

Calculating implied probabilities allows bettors to compare their own assessment of an event’s likelihood with the market odds. If your estimate is higher than the implied probability, the bet might offer good value.
