(+150, -200) Explained: How to Read American Moneyline Odds

Understanding how to read moneyline odds is a fundamental skill for anyone interested in sports betting. These odds are the most straightforward way to bet on the outcome of a game, simply by picking which team or individual will win. Represented by positive and negative numbers, such as +150 or -200, American moneyline odds directly indicate the potential payout for a correct wager on either the underdog or the favorite. Decoding these numbers is the first step toward making informed betting decisions.

The Foundation of American Moneyline Odds

When looking at sports betting lines, the moneyline is presented with a number preceded by either a plus (+) or a minus (-) sign. These symbols are essential as they immediately identify which team is the favorite to win and which is the underdog. Learning how to read moneyline odds begins with understanding this core distinction.

Identifying the Favorite and the Underdog

The two key components of any moneyline wager are the favorite and the underdog. Their roles are easily distinguished by the sign next to their odds:

• The Favorite: The team expected to win is indicated by a minus sign (-). Betting on the favorite offers a lower payout as the risk is perceived to be lower.
• The Underdog: The team expected to lose is indicated by a plus sign (+). Betting on the underdog involves greater risk but offers a significantly higher potential reward if they achieve an upset victory.

This simple plus-and-minus system forms the basis of all American odds, providing a quick visual cue about the perceived strength of each competitor in a given matchup.

How to Read Negative Moneyline Odds (The Favorite)

Negative odds are assigned to the favorite and show how much money a bettor must risk in order to win $100. This number is always greater than 100. The larger the negative number, the more heavily favored that team is to win the contest. For example, odds of -400 represent a much stronger favorite than odds of -150.

Calculating Potential Profit for Favorites

When you see a team with odds of -200, it means you must wager $200 to make a profit of $100. If the wager is successful, your total return would be $300, which includes your original $200 stake plus the $100 profit.

Of course, bettors are not required to wager the exact amount shown. The odds scale to any wager amount. The calculation is based on the ratio established by the odds. Here are a few examples using odds of -200:

• A $200 wager wins $100 in profit.
• A $100 wager wins $50 in profit.
• A $20 wager wins $10 in profit.

The core concept is that you are risking more than you stand to gain in profit. This is the premium for betting on the team that is statistically more likely to win the game outright.

How to Read Positive Moneyline Odds (The Underdog)

Positive odds are assigned to the underdog and indicate the amount of profit a bettor will win for every $100 wagered. This number always represents a potential profit that is equal to or greater than the amount risked. The higher the positive number, the greater the upset would be if that team wins, and consequently, the larger the payout.

Calculating Potential Profit for Underdogs

If a team has moneyline odds of +150, it means that a $100 wager will result in a profit of $150. Should the underdog win, the bettor receives a total payout of $250, which is their original $100 stake plus the $150 in winnings.

Similar to betting on favorites, the potential profit scales with the amount wagered. The ratio remains consistent. Using odds of +150 as an example:

• A $100 wager wins $150 in profit.
• A $50 wager wins $75 in profit.
• A $10 wager wins $15 in profit.

Betting on the underdog offers the chance to win more than the amount risked, which is the reward for taking on the greater risk associated with backing a team that is not expected to win.

Understanding the Total Payout

It is crucial to distinguish between profit and total payout. The profit is the amount won from the wager, while the total payout is the profit combined with the return of the original stake.

• Total Payout Formula: Original Wager + Potential Profit = Total Payout

For a winning $200 bet on a -200 favorite, the calculation is:

• $200 (Original Wager) + $100 (Profit) = $300 (Total Payout)

For a winning $100 bet on a +150 underdog, the calculation is:

• $100 (Original Wager) + $150 (Profit) = $250 (Total Payout)

Always remember that a successful wager results in the return of the initial stake in addition to any profits earned.
