This means for every $10 you want to win on a spread bet, you have to bet $11. If the odds were even (also represented as +100 in American sports betting), an $11 bet would have a payout of $11 (so a total return of $22). But at -110 odds, an $11 bet pays out $10 (total return of $21).

As for the odds, the most common number for spread bets is -110, but that number varies depending on the location, sportsbook and how popular each side is. The typical number is -110, which means you have to bet $110 to win $100.

What Does It Mean When Odds Are Negative? Negative numbers (in American money line odds) are reserved for the favorite on the betting line and indicate how much you need to stake to win $100—you generally need to put down more to win $100 on the favorite.

American Odds Example: if a bettor places a wager at -180, they must bet $180 to win $100. A bet at +300 signifies $300 is won for every $100 in wagers.

The team with a negative number (like -110) is the favorite. The number next to the minus sign is the amount you must bet to win $100 in profit. If the number is -110, you must bet $110 to win $100.

Are 100 to 1 Odds Good or Bad? 100 to 1 odds are good because they offer a high potential payout, but could also be seen as bad due to a low probability of winning (1%).

Note: The bottom team is always listed as the home team unless otherwise noted. The Braves' odds are -120, meaning a $12 bet would win $10, for a return of $22. The Dodgers' odds are +110, meaning a $10 bet would win $11, for a return of $21. On Today's Line we use a different format, the idea is the same.

What does -200 mean in sports betting? In sports betting, a negative money line (represented as -200, -300, -400, etc.) represents the amount of money that you need to bet in order to win $100 if your bet is correct.

So, for instance, let's say a moneyline favorite appears as -180 on the betting board. That minus sign indicates the amount of money one must wager to win $100. So a bettor looking to win $100 will risk $180.

Why do bookmakers always say 100/30 and not 10/3? It's traditional for bookmakers to use the odds of Burlington Bertie 100-30 as opposed to 10-3. In history 100-30 was used in case it was confused for a time (ie 2.50 pm which is 10 mins to 3) rather than a 10-3 price when spoken or signalled.

Thus if expressed as a fraction with a numerator of 1, probability and odds differ by exactly 1 in the denominator: a probability of 1 in 100 (1/100 = 1%) is the same as odds of 1 to 99 (1/99 = 0.0101... = 0.

A +100 odds line, on the other hand, means that you have the opportunity to win the same amount that you are wagering. Making a $100 wager at +100 odds means that you could win $100 on that bet.

With its odds set at +130, Team B offers a $130 payout for every $100 bet on it. So if someone were to bet on Team B, and Team B won, that person would win $130. A minus sign at the beginning of odds means the team is favored to win. The number indicates how much someone would need to wager in order to win $100.

Negative numbers signify the favorite on the betting line. The negative number indicates how much you'd need to bet to win $100. If the number is positive, you're looking at the underdog, and the number refers to the amount of money you'll win if you bet $100.

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.

Remember, positive odds indicate the underdog, and negative odds indicate the favorite. Exception: Sometimes, you'll come across both teams having negative odds.

You don't have to bet $100. Boston is the favorite at -175, meaning you must bet $175 for every $100 you hope to win. Whenever you see a minus-sign, that's how much you have to bet to win $100. In summary, minus + a number means you BET that amount for every $100 you want to win.

If you are betting on a longshot NFL futures bet at odds of 40/1 (these fractional odds convert to +4000 in American odds; decimal odds of 41.00), your implied chance of success is 2%.

With the standard 30-1 you'd get at most craps tables, bets on 2, 12 or hard hop bets give the house a 13.89 percent edge. If the payoff is 31-1, the edge drops only to 11.11 percent. True odds are 35-1, so there's a long way to go from 30-1 before these become viable bets.
