American sportsbooks have, over the years, presented their odds in a different way from the rest of the world. The odd format they employed is now widely known across the world as American odds. Also known as moneyline odds, the American odds format has grown popular among sports bettors in the United States, and is even employed in other forms of sports gaming.

Although a couple of sportsbooks have created room for a switch, the moneyline odd is the default odd type on American sportsbooks; as well as other offshore bookies that serve the American bettors.

Moneyline odds are expressed in positive and negative numbers and are based on wagering and winning \$100. The teams involved in an encounter are tagged favorite and underdog by the sportsbook. The favorite team has an odds that appears with a negative sign (-), while the underdog has an odd that appears with a positive sign (+). In a rare case in which both teams involved in the matchup are evenly matched, the two teams' odds come with a negative sign.

It has been clarified earlier that the lines of a favorite and an underdog in American odds are based on wagering and winning \$100. Thus, the odds of a favorite team indicate how much to wager in order to win \$100 while the odds of a matchup underdog indicate what can be won if \$100 is wagered.

Different Ways American Odds are Used

American odds are basically used by sportsbooks in two different ways;

• On their own

• With a point spread or totals

American Odds on their Own

In this situation, American odds is basically in the moneyline bet type, which is about picking the outright winner of an encounter. American odds in this variant can also be used for other bet types which include proposition, future, etc.

In a practical example, "Team A" locks horn with "Team B" with the following odds:

• Team A: -180 (Favorite)

• Team B: +340 (Underdog)

In calculating the potential payout in the above matchup, the \$100 base point in which the American odd is centered upon has to be made use of. Therefore, a stake of \$180 on "Team A" is required to get a profit of \$100, while an \$100 stake on "Team B" will return a profit of \$340.

• How to Calculate Profit

Moneyline odds can be calculated using a mathematical formula that provides a more comprehensive basis for calculating winnings. It is calculated as follows:

Odds/100 = Stake/x

Therefore, in calculating the profit if \$125 is wagered on the above Team A using the mathematical formula, we will get:

• 180/100 = 125/x

• Cross-multiply the equation to get 180x = 12,500

• Then solve for “x”; x = 12,500/180

• Final answer equal to = 69.44

Therefore, a profit of \$69.44 will be made when \$125 is staked, leading the payout of \$199.44

American Odds With a Point Spread or Totals

The other way the American odds are used is placing them next to a corresponding line in point spread and totals. In this situation, that odds dictates only what you have to risk and not what needs to occur for the bet to be won. For example;

• Team A: -5.5 (-110)

• Team B: +5.5 (+110)

In the above scenario, \$110 has to be risked for every \$100 aimed to be won when wagering on Team A which has to win by at least 6 points. It's pretty similar for Team B, \$110 must be risked for \$100 with the team winning the game or not losing by more than 5 points.

Since things equal are made equal by the spread, the spread in the game of football and basketball are usually -110 with a 10% tax. In sports that score less, the spreads are often low but the odds on each side will differ since it is more difficult for games like baseball, hockey, or soccer to win by more than a goal.
