How do betting odds work? Fractional, decimal and American odds explained and how to read them
Football betting odds are typically displayed in decimal, fractional or moneyline formats. In decimal odds, you might see odds like 2.50 on a football game, indicating that for every $1 wagered, you could win $2.50, including your original stake. Fractional odds could be presented as 3/2, where you could win $3 for every $2 wagered. The global sports betting market has exploded to over $85 billion, with bettors worldwide navigating different odds formats across platforms like Bet365, DraftKings, William Hill, and FanDuel. Whether you’re betting Premier League matches on European sportsbooks or NFL games on American platforms, understanding betting odds is your gateway to successful wagering. They reveal how bookmakers perceive each team or event and indicate your potential return on a winning wager.
In the end, we decided to play with those offering the highest paying odds, the most diverse set of betting types, and a fairly wide range of different sports. Throw in the big bonuses and easy financial transfers and what you get is one of the best sets of betting sites on the Internet. A parlay is multiple bets that all have to hit in order for the parlay bet to win. Using two of the examples above, let’s say a bettor wanted to build an NBA parlay featuring the Celtics -5.5 (-112) and Shai Gilgeous-Alexander Over 30.5 points (-120). By combining those two wagers, the parlay odds are now at +247. So a $100 bet on the parlay would have a potential payout of $347 ($100 initial stake and $247 profit).
For example, in the 2025 Super Bowl odds between the Kansas City Chiefs and Philadelphia Eagles, FanDuel Sportsbookclosed with the Chiefs at -118 and the Eagles at -108. Even though Philadelphia was the underdog in the game according to the sportsbook’s NFL odds, an Eagles bettor needed to bet $108 to win $100. The mathematics remain universal, but presentation varies dramatically. While DraftKings and FanDuel dominate American markets with their signature plus/minus system, Bet365 leads European markets with decimal formats that instantly show total returns. William Hill, steeped in British betting tradition, continues championing fractional odds that have defined wagering for pinup centuries.
Decimal to Moneyline Odds Conversion
- Decimal and fractional odds are more common outside the United States, but can be found in some American sportsbooks as well.
- In America, fractional odds are most commonly used in futures betting, where almost all the odds have a denominator of 1, making them easier to understand.
- Once again, betting on hockey is very similar to football, basketball and baseball; only some terminology has changed.
- For an NBA basketball game, the Boston Celtics could be -150 to win against the Los Angeles Lakers, who are priced at +130.
- Regardless, we are going to give you a little insight into these lines, as we want to give you insight about all of the common types of odds available.
Probability and implied probability are vital concepts in sports betting. Probability refers to the likelihood of an event happening, expressed as a percentage. Implied probability, on the other hand, is the probability of an outcome derived from the betting odds.
If the odds are listed as 6, a winning bet would receive a $5 profit and the original $1 bet. Anything between 1 and 2 is a favorite bet, and 2 is an even money bet. American odds are based on a $100 bet, but the relationship between the odds and $100 varies depending on whether the bet is favored or not. Another reason behind odds changing could be team and injury news in sports. New information can significantly alter potential probabilities. For example, if Erling Haaland and Phil Foden aren’t playing for Manchester City, their odds will drift as they’re less likely to win.

For hockey, sportsbooks also offer 60-minute lines, which give NHL odds based on three periods, not including overtime. While a bettor might find a “better” price on 60-minute lines than a standard money line, the bettor risks losing if the game goes into overtime. In American odds, a plus (+) sign shows how much profit you’d make on a $100 bet (underdog), while a minus (-) sign shows how much you need to bet to win $100 profit (favorite). For example, +150 means bet $100 to win $150; -150 means you must bet $150 to win $100. Mastering betting odds across global markets opens opportunities from Premier League matches on Bet365 to NFL games on DraftKings. Whether you prefer American moneylines, European decimals, or traditional British fractions, the mathematical principles remain constant while presentation adapts to regional preferences.
Understanding Vigorish Across Different Markets
This format is a third way to express the same odds, this time using decimals. This format is more common in continental Europe, Australia and Canada. Decimal odds represent the total return of the bet, including what was risked, for every dollar wagered. Fractional odds are the easiest to convert into probability percentages.
As new information and performance data emerge, odds can change drastically, reflecting the changing probabilities of the outcomes. Bettors should closely monitor the odds and consider the factors influencing their fluctuations to make well-informed betting decisions. Live betting is a dynamic and engaging way to enjoy sports betting, but it requires astute observation, quick thinking and disciplined decision-making. By understanding live betting odds and employing effective strategies, you can enhance your sports betting experience and potentially boost your profits.
See how to convert each format of odds to an implied probability in the following section, where you’ll see each type of the betting odds explained. Betting odds can help you identify heavy favorites and underdogs in a given matchup. The moneyline favorites are teams or players expected to win, indicated by lower odds. For instance, if Team A has -200 odds against Team B with +150 odds, Team A is the favorite. Underdogs, on the other hand, are expected to lose and have higher odds. By placing an underdog bet, you’re less likely to win but you will receive a larger payout if you place a successful wager.
Fractional odds are most commonly used in the UK and they’re expressed as a ratio, such as 5/1 (pronounced five to one). A £10 bet on a 5/1 play means you would win £60, with £10 of that being your original stake. If the decimal odds are less than 2.00, the moneyline is negative (-).
The potential payout is the total amount you stand to win from a successful bet, including the original stake. By understanding how odds correspond to potential winnings, you can make educated decisions on the amount you want to wager and assess the risk-reward ratio of different bets. Comprehending betting odds is critical for successful sports betting. It allows you to make well-informed decisions, assess risk and reward accurately and identify potential value bets.
