Odds tell you how much you can win and how likely an outcome is. Learn to read the three common formats.

Decimal odds

Decimal odds show your total return per unit staked. Odds of 2.50 return 2.50 for each 1 bet, which includes your original stake.

Fractional and American odds

Fractional odds like 5/2 show profit relative to stake, so 2 staked wins 5. American odds use plus and minus numbers to show profit on 100 or the stake needed to win 100.

Odds and probability

Odds imply a chance of winning, and bookmakers add a margin to every market. Comparing prices helps you avoid paying more than you need to.
