    Specific Bet Type Calculators

    Arbitrage Calculator

    If you are looking for odds payout chart for Arbitrage betting, you've gone to the right place. Arbitrage betting involves wagering on every potential outcome of an event at odds which guarantee a payout. These types of opportunities don’t arise often, but every now and then, you might come across a scenario where hedging your bets guarantees a win. The odds value calculator is extremely handy in these situations.

    Arbitrage calculators will provide the winnings you can earn according to the odds and betting amount given. In some cases, you’ll be able to figure out how much you’ll be able to win by hedging your bet. These type of price discrepancies don’t occur frequently on the betting market, so it’s worth your time to verify the numbers. 

    Freeplay Value Calculator

    Similar to arbitrage calculators, freeplay calculators give you an opportunity of setting up a risk-free hedge. In this case, you calculate the odds and the hedged amount according to the amount of bonus currency given to you by the sportsbook. This type of calculator doesn’t determine rollover requirements, which vary between sportsbooks.

    Half-Point Calculator

    This type of sports odds calculator deals with points spreads and totals, usually for basketball, football and college competitions.

    When betting the spread on an NBA game, you have the opportunity to buy or sell half points to increase the profitability or reduce the risk of the spread.

    A favorite with a spread of -3.0 could be more profitable if you buy a half point, increasing the spread to -3.5. This adds risk to the wager, with a corresponding boost to payout. The bet now loses instead of a push when adding the half point, requiring a four-point win to pay off.

    Kelly Calculator

    John Larry Kelly Jr. was a scientist who figured out a way to determine an optimal betting amount according to bankroll and the type of odds you face when sports betting. Since pros tend to work with a long-term strategy, a Kelly Calculator helps to determine a standard betting amount which performs well. This way, if you tend to win half of your bets at odds around +120, the Kelly Calculator may suggest a specific percentage of your roll to wager for each event.

    Parlay Calculator app

    When you’re stringing together a multiple bet parley, you can enter the odds of each individual bet and the stake wagered into a parlay calculator app to determine the value of the parley. 

    This type of parlay calculator’s useful when determining the value of different parley possibilities, while double-checking the value provided by your sportsbook. 

    Poisson Calculator

    One of the more complex type of calculations, Poisson probabilities are most often used in sports to approximate the strength of offensive and defensive capabilities of a team, compared to the rest of the competition.

    Attack strength for an NHL team would be calculated by measuring the average goal production for the entire league and comparing the results with an individual team. Defensive strength is calculated by comparing the average number of goals allowed league-wide with a single team. 

    These numbers then inform probability distributions, giving you an idea of the chances that a team will score or allow a specific number of goals. Poisson distributions may be utilized to determine percentages for outright winners, spreads and over/unders.  

    Reverse Bets Calculator

    Reverse bets are similar to parleys because both types of wagering involve two or more events. While parleys require the correct prediction of all events listed, the win conditions for reverse bets are more complex.

    Most reverse bets involve two wagers which begin with a single bet, followed by a ‘win, tie, or cancel’ condition. If a specific team wins, then the second bet proceeds. The second part of the reverse bet flips the two wagers, with the same conditions.

    This improves the potential profit of the wager, while maintaining a similar loss if only one or none of your bets win. Since reverse bets involve complicated “if/then” structures, they’re often limited to two wagers.

    Round Robin Calculator

    A round robin calculator informs you of the potential profit and peril of creating a series of multi-team parley bets. A three-team round robin bet would consist of three two-team parleys. If one of the three parleys wins, your initial stake is returned, while if two or more parleys win, the profit of your wager jumps.

    Three team round robins tend to be easier to mange than longer round robin bets due to all the different permutations when dealing with four or more wagers.

    Streak Calculator

    A streak calculator provides a rough approximation of the chances of winning a series of bets given a specific set of odds. 

    How To Calculate Sports Odds Payout

    American Odds Calculation

    Calculating odds payouts for yourself isn’t too difficult, even when you’re using American-style odds. For positive moneylines, divide the moneyline by 100 and then add one to the result. This will give you the decimal version of the odds, which you multiply by the amount of money you wager.

    +150 :: (150/100) + 1 = 2.50. $100 x 2.50 = $250.

    For negative odds, divide 100 with the moneyline, before adding one to this number. Multiply your wager by this result to determine payment for negative moneylines.

    -150 :: (100/150) + 1 = 1.67. $100 x 1.67 = $167

    Fractional Odds Calculation

    Fractional odds require a single equation to determine your winnings, unlike American odds, which have different calculations according to plus and minus symbols.

    In order to calculate fractional winnings, divide the first number of the fraction with the second number, and add one to the result. Multiply this number with the amount of money wagered to determine the winnings.

    3/5 :: (3/5) + 1 = 1.60. $100 + 1.60 = $160

    Decimal Odds Calculation

    Simply multiply the odds with the amount of money you bet – 2.67 :: 2.67 x $100 = $267.

    Specific Odds Converters

    Odds Converter

    Sports betting odds feature different formats around the world, including three main types utilized in most North American and Euro markets.

    American moneylines feature a plus to denote the underdog and a minus for the favorite, while British and European standards feature decimals or fractions.

    Odds converters allow you to plug one type of odds format into the system, which converts this figure into other formats. The best odds converters offer all the different formats around the globe, including Malay, Indonesian and Hong Kong styles.

    Spread/Moneyline Converter

    Moneylines and spreads tend to be the more popular types of wager, but it can be difficult to select between the two when determining which has more value. Essentially, the moneyline offered should correspond to a point spread that has an equal risk/reward ratio.
