    Odds Formats Supported by Our Bet Calculator

    There are three main formats: fractional, decimal and American. Each format shows odds differently but in all cases, they translate into the same. In Canada and the US most bookmakers work with American or Decimal odds. Our calculator supports all three formats and allows you to switch in between them without affecting your results.

    You may insert your odds, as given by the sportsbook and switch in between them to get an automatic conversion if you prefer working on, for example, Decimal odds but were given American odds. We also offer an odds converter that you can try to free.

    Let’s explain shortly each of the Odds formats and some examples.

    American Odds

    Positive American odds (e.g. +150) is the amount you’d win on a $100 bet, negative American odds (e.g. -150) is the amount you need to bet to win $100. This helps you evaluate risk and reward. Most bookmakers use American odds for sports like basketball and football.

    Decimal Odds

    Decimal odds show the total return on a bet including the original stake. For example, decimal odds of 6 means a $1 bet would return $6. These odds are useful for sports with three possible outcomes like soccer. Decimal odds are used in European countries.

    Fractional Odds

    Fractional odds, used in the UK and Ireland, quote the potential profit relative to the stake. For example 3/1 means you’d win 3 units for every 1 unit staked. This format helps you quickly see the value offered by different bookmakers.

    Betting Types Explained Through a Bet Calculator

    illustration of the maths behind bets

    Our bet calculator helps you calculate returns across different betting types, from moneyline bets to spread bets. Let’s breakdown the main types:


    Moneyline betting is picking the winner. Positive figures like +200 on a $100 bet would return $300, negative figures like -110 would require a $110 bet to win $100. The calculator shows the implied probability so you can see the value of your bet. Moneyline is used in American sports betting.

    Spread Betting

    Spread betting is predicting the margin of victory. The bookmaker sets a line and the calculator helps you calculate the returns based on the spread and odds.


    Over/under betting is the total score. Betting the OVER means high scoring, betting the UNDER means low scoring.

    An odds betting calculator is a tool used to calculate potential payouts from various types of bets. It allows bettors to input the odds, in various formats, and the amount they plan to wager. The calculator then computes potential profits based on these factors.
    An odds betting calculator can provide you with a clear understanding of potential returns on a bet, which can inform your betting strategy. It helps remove the complexity from calculations, particularly when dealing with odds in different formats (decimal, fractional, or moneyline). This allows you to focus more on making informed betting decisions and less on math.
    Yes, they are. An odds betting calculator is simply a tool that provides information about potential betting outcomes. It does not influence the outcome of a bet or facilitate betting in any way. Remember that while betting itself is legal in Canada, each province sets its own regulations, so it’s important to be aware of the rules in your particular province.
    Using an odds betting calculator is straightforward. You typically input the type of odds you are working with (decimal, fractional, or moneyline), the specific odds for the event you are betting on, and the amount you wish to wager. Once you’ve input this information, the calculator will display the potential payout should your bet be successful.
    Many odds betting calculators are designed to work with a range of bets, including single bets, accumulator bets, each-way bets, and more. However, the types of bets a calculator can handle depend on its specific features and design. Always ensure the calculator you are using is suited to the type of bet you’re placing.
    American Odds are the default odds at American sportsbooks. These odds are based on winning $100 for a given bet. Betting a Favorite: The odds for favorites will have a minus (-) sign, and represent the money you need to risk to win $100. So if you’re betting on the Packers at -140 against the Vikings, that means Green Bay is a slight favorite. You need to risk $140 to win $100 on the Packers. If they win, you profit $100 and get your original $140 back. Betting an Underdog: The odds for underdogs will have a plus (+) sign in front, and represent the money you can win for every $100 risked.
    The rest of the world uses Decimal Odds, in part because it’s easier to convert them to implied probabilities than American Odds. Decimal odds represent the amount a bettor wins for every $1 wagered. And the number represents the total return, not just the profit like American and fractional odds.
    Fractional Odds are used primarily in the UK and Ireland. Few bettors use fractional odds for betting sports (other than horse racing), because the conversions to understand return are difficult. To calculate winnings on fractional odds, multiply your bet by the top number (numerator), then divide the result by the bottom (denominator). So a $10 bet at 5/2 odds is (10 * 5) / 2, which equals $25. A $10 bet at 2/5 odds is (10 * 2) / 5, which is $4.

    Odds correlate to the probability of a team winning, which is the implied probability. A -140 favorite has about a 58.34% chance of winning, while a +120 underdog has a 45.45% chance.

    Did you notice those percentages add up to more than 100%? That’s because of the vig, which is a sportsbook’s cut for facilitating your bet. To calculate implied probability, use the following formulas:

    For negative numbers (favorites), drop the minus sign, then do:

    Negative Odds / (Negative Odds + 100) * 100

    For positive numbers (underdogs):

    100 / (Positive Odds + 100) * 100

    Your payout includes your potential winnings, plus whatever you bet originally. So if you bet $10 on a +150 underdog, your payout will show $25.
