How betting odds work: what they are and how to use them
For example, 6/5 fractional odds (also described as „1.2“ or „6 to 5“) are the same as 11/5 decimal odds (also described as 2.2 or „11 for 5). A variation of fractional odds is known as Hong Kong odds. However, not all fractional odds are traditionally read using the lowest common denominator (i.e. simplifying the fraction when possible). In either case, having won, the bettor always receives the original stake back too; so if the odds are 4/1 the bettor receives a total of £500 (£400 plus the original £100). Favoured by bookmakers in the United Kingdom and Ireland, and also common in horse racing, fractional odds quote the net profit that will be paid out to the bettor, should they win, relative to the stake. That value may be regarded as the relative probability the event will happen, expressed as a fraction (if it is less than 1), or a multiple (if it is equal to or greater than one) of the likelihood that the event will not happen.
Prop bets, short for proposition bets, focus on specific events or outcomes within a game, rather than the final score. Since these bets can be made months in advance, they offer a chance for big payouts, especially when backing underdogs. Instead of betting on a single game, you’re predicting outcomes like who will win the NBA championship, MVP award, or a division title.

Multiplying these probabilities by 100% gives the percentage. When probability is expressed as a number between 0 and 1, the relationships between probability p and odds are as follows. When Moneyline odds are quoted as a positive number +X, it means that a wager pays X to 100.

Some bets involve combining multiple outcomes for higher rewards, while others target specific in-game events or achievements. Once you’re familiar with the basic math, fractional odds become an easy way to see potential profits relative to the stake. They’re especially popular in horse racing, where bettors often look for value in underdog picks or assess returns more precisely using this format. Fractional odds can be a bit trickier to calculate quickly, but they’re favored by many bettors for how clearly they represent the risk-reward ratio.
The odds or amounts the bookmaker will pay are determined by the total amount that has been bet on all of the possible events. Sports information services are often used by professional and semi-professional sports bettors to help achieve this goal. It was about 3.7% less for wins by the visitors, and 5.7% less for draws. A study on soccer betting found that the probability for the home team to win was generally about 3.4% less than the value calculated from the odds (for example, 46.6% for even odds). The total of these three percentages is 100%, thus representing a fair ‚book‘.
For instance, if the line is 220.5 in an NBA game, you’d bet on whether the teams‘ combined score will be over 220 or under 220.5.
