How Sportsbooks Odds Work

Bettors want to enjoy their betting indulgence when they know how to place their bets by understanding how sportsbooks odds work. An amateur punter would choose his favorite team regardless of odds proposed by a betting entity. But to those who are not new to this form of entertainment, they would understand how to make money by choosing the right betting options presented in the online betting platforms.

If you want to make money in this trade, one must learn and understand how to use the betting propositions offered by bookmakers in their sportsbooks. Learning how sportsbooks odds work on betting sites will allow punters to choose wisely and place their bets in an intelligent manner.

How Sportsbooks Odds Work: The Price of a Wager

Odds determine the amount paid to winning bets. The wager can either be for the odds or against it. When a betting option is an “Odds On”, the team or athlete selected is known to be much better than his opponent. They are the favorite to win the event and bettors could get a winning payout if he wins. Since it is easier to win on an”odds on” option, the punter will receive lesser rewards. 

If a bettor opts for the “Odds Against” selection, the gambler is rooting for the underdog to win the match. Thus, it would not be an easy bet and therefore, punters get greater rewards for their wagers. Game favorites often are on the “odds on” side while underdogs usually get the “odds against” option.  

Odds Format on a Sportsbook

There are three main odds formats used to present betting options. Bettors will come across this format when navigating on various betting sites on the clouds. Understanding how sportsbooks odds work and their formats is essential to your betting options.

  • Decimal Format

Most betting platforms use the decimal  type of format in American based betting sites. It is the simplest and easiest form to understand. The decimal based figures show how much a punter wins if he bets on the odds presented by a bookmaker on his website.

Example, a $100 bet on a 1.50 odds will win $150. The punter selected the favorite on this example as he got a lesser reward in his bet. He only earned $50 because of the 1.5 “odd against” option. If the bettor chose the 2.00 odds line, he will win $200 from his bet of $100. If he placed 100 at 3.50, he will receive a $350 payout for his $100 stake. 

The formula is wager multiplied by odds equals the potential payout. Therefore, calculations for your profit are wager multiplied to odds – 1 is equal to the profit of your bet. 

How Sportsbooks Odds Work

  • American Moneyline

The moneyline odds are also known as the American format presented to punters on sportsbooks. This odds format is mainly used in the United States and is a little confusing but a punter will get the hang of it in no time. 

MoneyLine has a positive or a negative sign preceding the figure it denotes. A positive sign on a150 moneyline (+150) will have a potential return of $250 on a $100 bet. An example would be a $500 bet at odds of +125 will have a potential return of $1,125. 

Another example is betting $150 on an odd of -150 will win you $250. A $200 wager on an odd of -105 will have a winning potential of $390.48. Thus, the formula for the American Moneyline format is Bet (odds/100) is equal to your potential profit for  positive moneyline. For the negative lines, Bets / (odds/100) for your earnings on the wager. If you wish to know the potential returns of your bet, just add the wager amount.

  • Fractional Odds Format

The fractional format is common in the United Kingdom sportsbooks and race track offerings. This form of betting is slowly being replaced by the decimal format for the betting piblic’s convenience. 

An example of this betting format is 2/1 which is stated as two is to one; 7/4 stated as seven to four or1/2 (two to one on). Derivative of the formula wager x  (a/b) = profit. So, if you bet $100 on an odd of 2/1 your potential profit will be $200. A $100 wager on an odd of 7/4 makes a payout of $175. 

Odds, Probable Results and Implied Probability on Outcome of Events 

Odds and probability may be the same. But odds offered in sportsbooks could not directly predict the outcome of the games. Certain events may occur during the game that could turn an underdog into the favorite to win the match, and injury for instance. 

The Probability of a team winning a contest would suggest how you made the research of the opposing teams. The analysis includes player performance, statistics, and a clean healthy roster that comes along with the probability of a team over another. 

Implied probability will lean on how the odds presented to the betting public. It can help bettors perform a calculated risk on the bookmakers advantage and determine if the odds offered are of any value in the market. The formula for Implied Probability (IP)  is 1/decimal odds. Therefore, if a decimal odd is 1.5, the Implied Probability for a team to win the game is .666 or 66.6%.

Balance Betting Entries and The Overround

Online bettors who are familiar with how bookmakers make money would likely cash in on balanced books and overrounds. The aim of bookies is to take in more losing bets than the doling out payouts on winners. If they see that more bets are coming in for the favorite team,they could tweak on the betting odds to limit wagers favoring the leaning winner of an event. 

Bookmakers will apply the overround to attract bettors by offering attractive odds. If the odds are sold out, then a balanced book will be good for the bookie. The overround or the vig/juice will make the earnings for the books.
