Understanding American Odds: How American Odds Work

American odds, also known as “Money line” or “U.S.” odds, are a popular format used in the United States for sports betting. This article aims to provide a clear and concise explanation of how American odds work, including converting them to decimal and fractional formats. By understanding American odds, you can make informed betting decisions and better navigate the world of sports betting.

What are American Odds?

American odds are represented by numbers accompanied by a plus (+) or minus (-) sign. The plus sign indicates the amount you could win for every $100 staked on the underdog, while the minus sign represents the amount you need to wager to win $100 on the favorite.

Positive American Odds

When you come across positive American odds, such as +200, it signifies the potential winnings for every $100 bet. For instance, a +200 bet means you could win $200 in profit, in addition to your initial stake of $100, resulting in a total payout of $300.

Negative American Odds

Negative American odds, like -200, are reserved for the favorite. They indicate the amount you need to bet in order to win $100. For example, a -200 wager would require a $200 bet to potentially win $100. If successful, you would receive a total payout of $300 ($200 net profit + $100 initial stake).

Converting American Odds

Converting American odds to other formats, such as decimal or fractional odds, can be helpful for comparing odds across different platforms or understanding alternative odds representations.

Decimal Odds Conversion
To convert American to decimal odds, you can use the following formula: Decimal Odds = (American Odds/100) + 1. For example, a +200 American odds converts to decimal odds of 3.00, indicating a potential total payout of $300 for every $100 staked.

Fractional Odds Conversion
Converting American to fractional odds involves expressing the potential winnings relative to the amount wagered. For example, +200 can be expressed as 2/1, meaning you could win $2 for every $1 bet.

Understanding Implied Probability

Implied probability represents the likelihood of an outcome based on the odds provided. Positive American odds reflect a lower implied probability of winning for the underdog, while negative American odds indicate a higher probability of winning for the favorite. The greater the difference between the odds for the favorite and the underdog, the wider the perceived probability gap.
