The first thing you’ll notice with moneyline odds is that there is either a positive or negative sign in front of the number. What that sign denotes is how much you’ll win betting on each side. If there’s a positive sign next to the odds, that indicates the amount of money you would win if you bet $100. If the odds on a tennis player said +150, that means that for a $100 bet, you would win $150. Now if there is a minus sign in front of the odds, that is the number that you would have to bet in order to win $100. For example, if a football team was -250, that means you’d have to bet $250 to win $100.
We do want to make sure to point out that this is total money returned and not your profit. We went over the difference above when discussing the American odds. Let’s take a look at the same bet again, but this time with decimal odds. We should be expecting to see a profit of $33.33 for an Eagles bet and $240 for a Falcons bet since we know that the bets are the exact same and are just presented in a different format.
Identify the favorite. Lines with a - before the number (i.e. -200) indicate the favorite. A -200 should be read as: "For every $200 wagered, I win $100." When there is a negative sign, the line should always be read with relation to 100. That does not mean you have to bet that much, it's just easiest to understand! When a + sign is present, just reverse the reading, always keeping reference to 100:
In football the money line is often a popular choice for bettors who have been burned by last-second scoring that actually had no actual affect on the outcome of the game. With the money line you just have to hope your team wins rather than cover a point spread. Of course, the one downside is having to risk more money to return the same amount that a point spread bet would net you.
In this example, we have a favorite to win, and an underdog. The Packers are the favorites, and that is shown by the (–) value in front of the 6. Underdogs are represented by the (+) value. The 6 point value is how many points either team could win, or lose by. If you think the Packers will win by MORE than 6 points, then you’d bet on the favorite in this case, meaning that the Packers have to win by 7 or more points in order for you to win your bet.
