What Are Betting Odds?
Betting odds are numerical representations of the likelihood of an event occurring. They are used to calculate the potential payout of a bet and to indicate the degree of risk involved in a particular wager. For beginners, understanding odds is crucial to developing a sound betting strategy. If you're new to sports betting, start with our guide on expected value to understand how odds affect your potential profit.
Betting odds can be expressed in different formats, such as fractional odds, decimal odds, or moneyline odds, depending on the region or sportsbook offering them. If you're looking for tools to help with calculating or converting these odds, try our Betting Odds Calculator.
What Do - and + Mean in Odds?
The minus (-) and plus (+) signs are used in moneyline odds to indicate the favorite and underdog in a particular betting market. The minus sign represents the favorite, while the plus sign represents the underdog. This is particularly common in American odds, and knowing how to interpret these signs is essential for understanding risk and potential payout.
In a moneyline bet with a favorite, the odds will have a minus sign (-) in front of the number, such as -150. This means you need to bet $150 to win $100. Conversely, in a moneyline bet with an underdog, the odds will have a plus sign (+), such as +200, indicating that a $100 bet would win you $200.

Implied Probability and Odds
Implied probability is a crucial concept in sports betting, as it translates the odds into the likelihood of an event occurring. It is calculated by dividing 1 by the decimal odds and multiplying by 100. For example, if the odds of a coin landing heads up are 1.5, the implied probability is 1 / 1.5 * 100 = 66.67%. Understanding implied probability can help you identify when a bet offers good value, which is a key aspect of value betting.
To simplify these calculations, use our Betting Odds Calculator to quickly convert odds into implied probability and vice versa. Implied probability plays a significant role in recognizing profitable bets and avoiding traps set by the bookmaker's margin.
What Is Vig (or Juice)?
Vig, short for vigorish or juice, refers to the commission that a bookmaker or sportsbook takes on a bet. It’s essentially how sportsbooks ensure a profit over time, regardless of the outcome. For example, if a bettor places a $100 bet on a team to win, and the odds offered are -110, they would have to pay a vig of $10. This fee impacts your betting strategy and potential ROI.
Understanding and minimizing the impact of the vig is an important aspect of sports betting. For more insights on how to navigate this, visit our sports betting financial strategies guide.
What Is Hold?
"Hold" refers to the percentage of the total amount of money wagered that the sportsbook keeps as profit. For example, if a sportsbook takes in $100,000 in bets and pays out $90,000 in winnings, the hold would be $10,000, or 10%. A high hold percentage means the sportsbook is keeping more of the money wagered, which can affect the odds offered to bettors.
Understanding the hold percentage is crucial when evaluating sportsbooks. To manage risk effectively and identify favorable odds, check out our guide on hedge betting.
Types of Betting Odds
American Odds
American odds, also known as moneyline odds, are primarily used in the United States. When expressed as a negative number, it indicates how much you need to wager to win $100. Conversely, a positive number shows how much you can win by betting $100. If you're exploring American odds in depth, take a look at our guide on arbitrage betting to learn how these odds can be leveraged for guaranteed profit.
Fractional Odds
Fractional odds are commonly used in the UK and Ireland and are expressed as fractions (e.g., 2/1 or 7/2). The first number represents the potential profit from a winning bet, while the second represents the amount staked. For instance, 2/1 odds mean a $1 bet results in a $2 profit. To easily convert these odds into other formats, use our Betting Odds Calculator.
Decimal Odds
Decimal odds are popular in Europe, Australia, and Canada. They are expressed as a decimal number (e.g., 1.50 or 2.25) and represent the total payout, including the stake. For example, with odds of 2.50, a $1 bet would result in a $2.50 payout. For more on how to use decimal odds to your advantage, check out our sports betting financial strategies guide.
Calculating Payouts
Understanding how to calculate potential payouts for different odds types is essential for managing your bets:
- Fractional Odds:
- Potential Payout = (Stake x numerator) / denominator
- Profit = Potential Payout - Stake
- Decimal Odds:
- Potential Payout = Stake x decimal odds
- Profit = Potential Payout - Stake
- American Odds:
- If odds are negative (-): Potential Payout = (Stake / absolute value of odds) x 100
- If odds are positive (+): Potential Payout = (Stake x odds) / 100
- Profit = Potential Payout - Stake
For a quick and easy way to calculate potential payouts, use our Betting Odds Calculator.
