Fractional Odds
Fractional odds are also known as traditional odds. They are widely used at sports betting sites in the UK. Fractional odds are quoted as a fraction indicating the amount that would be paid out relative to a given stake. Therefore, if you see fractional odds of 4/5, you would earn an $8 profit for every $10 you stake.
Decimal Odds
Decimal odds are often used outside of the US, UK and Ireland. They tell you the return you should expect to receive based on your bet amount if your bet pays off.
American Odds
American odds start with a plus or a minus symbol. If the line starts with a plus, it tells you the amount of profit you would earn from a $100 bet if your wager proves to be successful.
Probability%:
Odds are related to probability. For example, odds of 5/1 mean that it is expected to win once in every 6 attempts. Therefore, the probability is 16.67%.
