Margin calculator

Enter the odds for every outcome of one market. The margin is the bookmaker's built-in edge - the lower it is, the more of your money comes back over time.

What the margin actually is

Convert every outcome's odds to implied probability (1 divided by the decimal odds) and add them up. A fair market totals exactly 100%. Real markets total more - 104% to 108% is typical on football 1X2 - and that excess is the margin: the bookmaker's fee, baked invisibly into the prices.

Why it decides where you bet

A 3% margin book pays you meaningfully more than a 7% margin book for the identical prediction, every single time, forever. Comparing margins across bookmakers is the single most mechanical way to lose less - no forecasting skill required. Sharp markets (top-league main lines, Asian handicaps) carry the lowest margins; obscure leagues and specials carry the highest.

Holding accounts at several low-margin books and moving between them freely is the whole point of the wallet setup - one balance, always the best price.
