Frequently Asked Questions
What is overround in betting?+
Overround is the amount by which a market's combined implied probabilities exceed 100%. It represents the bookmaker's built-in margin across all outcomes. Read the bookmaker overround guide.
How do you calculate bookmaker margin?+
Convert each outcome's odds into implied probability, add them together, then subtract 100%. For decimal odds, implied probability is calculated as 1 / decimal odds.
Is a lower bookmaker margin better?+
Usually, yes. A lower margin means the market is priced closer to fair value, reducing the built-in disadvantage for bettors.
