Overround 2.64%
The 1X2 market prices three results: home win, draw, away win. The draw is the leg bettors most often forget when checking whether prices form an arbitrage, and it is also where bookmakers disagree most, which makes 1X2 one of the richer markets for cross-book comparison.

Soccer 1X2 (match result) has 3 outcomes (
Home, Draw, Away). Bookmakers usually price it with an overround between 3% and 8%. Sharper books sit at the low end; recreational books and multi-way fields at the high end.

Sample prices of 2.20 / 3.40 / 3.60 carry an overround of 2.64% (margin 2.58%). Multiplicative devigging gives fair probabilities of 44.3% / 28.7% / 27.1% and fair odds of 2.26 / 3.49 / 3.70. The calculator above starts from these prices and shows every method side by side.
| Outcome | Odds | Implied | Fair probability | Fair odds |
