Betting odds explained: guide to how betting odds work

The calculator will then determine how much your winnings would be if you placed a $100 bet on that outcome. Known as "European" odds and "digital" odds, these are used across Europe, Canada, Australia and New Zealand. Their main advantage is that one can instantly spot who is the favorite and who is the underdog – the former will have the lowest odds and the latter – the highest.

  • If the bet works out, the player would receive a total payout of $300 ($200 net profit + $100 initial stake).
  • You can bet OVER or UNDER the oddsmaker’s line of 30.5 points for The Beard.
  • Fractional odds of ⅘ is equivalent to an American odds of -125 and a decimal odds of 1.80.
  • Moneyline Odds – When wagering in positive moneyline odds, the amount that can be won will be more than the amount bet.
  • When odds are expressed with a plus (+) or minus (–) symbol followed by a number.

Odds typically refer to the ratio between the probability of one event happening versus another where the two events are mutually exclusive and exhaust all possible outcomes. In simple games with dice it could be the odds of rolling a sum of five with two six-sided dice versus not rolling it. The odds of that happening versus not happening are one to nine. Alternatively, we have nine to one odds for not rolling a sum of five. You might be able to guess what the payout could be based on the odds but in case you can’t do the math (or don’t want to) our betting odds calculator can do the work for you. For example, a bookmaker has the (fractional) odds of Man City defeating Crystal Palace at 8/13. Plug the numbers into the formula, which is a simple matter of dividing 8 by 13 in this example, and the implied probability equals 61.5%.

This positive difference between the true odds and the implied odds is your edge in a bet, and one should only take a bet if they have an edge. In other words, if they believe the other party’s implied probability is underestimating the true probability of the event happening. In conclusion, betting odds play a significant role in shaping a bettor’s decision-making process and determining potential returns on wagers. By understanding how these odds are calculated and what they mean, you can make more informed decisions and increase your chances of placing successful bets. Understanding is essential for anyone interested in sports betting. Knowing how odds work and how to convert them into implied probability allows you to make more informed decisions when placing bets.

A minus sign before the number indicates how much you need to bet to earn a net profit of €100. For example, with odds of “-500,” you need to bet €500 to win €100. In Moneyline odds, a minus sign before the number indicates that it’s a bet on the favorite. This notation includes all odds that would be under 2.0 in decimal odds. If there’s a plus sign before the number, it indicates a bet that corresponds to a decimal odd of at least 2.0. The decimal odds indicate the amount you will receive for every euro you wager. The wager is already included in the decimal number, which makes the calculation easier.

Since there can’t be a draw in normal time, there will also be odds for each team winning the match in extra time and odds for each of them winning through penalties. The probabilities of each outcome will be determined and transformed into the odds that we have come to be familiar with. Generally, the probability behind the odds is equal to your stake over the total payout. Bookmakers take all the data they can manage into consideration before offering their odds. A very simple explanation of probability would be a coin toss, in which the two possible outcomes are heads or tails. The probability of getting heads is a one in two chance, which can be represented as odds of 1/1, which would mean the outcome has a 50% chance of winning. This is how punters can use the betting odds to work out how likely bookmakers believe an outcome is to happen.


This is because in American roulette, unlike European roulette, there is not only a zero on the wheel, but also a double zero. So, although there are a total of 38 possibilities where the ball can stay in the wheel, the payout odds remain the same as in European roulette with only 37 possibilities. Hong Kong odds of 1.5 correspond to decimal odds of 2.5, so you only need to add “1” to Hong Kong odds to get European decimal odds. American odds certainly take some time to get used to for Europeans, but they have the advantage that the net profit can be read at a glance for odds with a “+”.

What is implied probability in sports betting?

The difference between the odds for the favorite and the underdog widens as the probability of winning for the favorite increases.

You can do this directly on our site by selecting “American” or “Decimal” as the input type.

The amount by which the implied probability diverges from 100% is the edge your bookmaker holds for that market, and essentially measures the value they are providing. Once you get past that hurdle, you can compare odds between bookmakers. However, if you consider betting to be just about odds, you’re missing the bigger picture. To really expand your understanding of odds and betting, you must also understand how to calculate probability. American money lines are used and include a point spread and the total number of points the bookmaker thinks will be scored.

A bet on the over means there is a probability that both teams will combine to score more goals, points, or runs than the total listed. Conversely, an under bet means you think there will be fewer goals or points than the total listed. Prop betting is a wager based on the occurrences and non-occurrences of an event. These incidents may not correlate with the event’s outcome, unlike points spread, futures or totals.

Blackjack is not only the most popular card game in the casino, but also the game with the lowest house edge that players have to compete against. Therefore, good blackjack players have a decent opportunity to collect long-term winnings from the casino with the right strategy.

The last example illustrates quite well the disadvantages of English fractional odds, as especially inexperienced bettors find it sometimes difficult to convert odds in their heads.
