# What Does Minus 310 in Sports Betting Mean?

If you’ve ever placed a bet on a sporting event, you may have seen the term “minus 310” at some point. But what does it mean?

## Introduction

In sports betting, odds are created by the bookmakers to represent the probability of an event occurring. The bookmakers will set the odds based on their own analysis of the event, and these odds will then be used to determine payouts for winning bets.

Odds can be displayed in several different ways, but the most common way to see them is as a fraction. For example, if you see odds of 3/1 for a horse race, this means that for every £1 you bet, you will win £3 if the horse wins.

The fraction can also be displayed as a decimal, which is how it is most commonly seen in football betting. For example, odds of 3/1 would be displayed as 4.00. In this case, for every £1 you bet, you would win £4 if the team won.

You may also see negative numbers used when displaying decimal odds. For example, odds of 3/1 would be displayed as -333. This means that you would need to bet £333 to win £100.

## What Does Minus 310 Mean?

Minus 310 is a term used in sports betting that refers to the favorite in a game. The minus sign indicates that the team is favored to win, while the number 310 indicates how many points they are favored by.

### Decimal Odds

In sports betting, odds are shown using what is called the “odds format.” The three most common ways of representing odds are fractional (2/1), decimal (3.0), and American (-200). Of these, the fractional and decimal methods are by far the most popular.

In the fractional system, odds are displayed as a ratio of the amount you will win if you make a bet to the amount you need to wager in order to make that bet. For example, if odds are displayed as 2/1, this means that for every \$1 you wager, you will win \$2 if your bet is successful. In decimal form, these same odds would be displayed as 3.0.

American odds are slightly different in that they represent how much you need to wager in order to win \$100. So, if American odds are -200, this means that you would need to wager \$200 to win \$100. These odds are not as popular as fractional or decimal odds because they can be a bit confusing for newcomers to sports betting.

### Moneyline Odds

In sports betting, odds are the price offered by a bookmaker or betting site to customers. The odds represent how likely something is to happen, and how much you could win if it does. Odds are usually expressed as fractions (2/1, 3/5 etc.), but can also be given as decimals (2.00, 3.50 etc.) or Americans odds (-200, +300 etc.).

The number on the left is how much you need to stake to win the amount on the right. So, 2/1 odds means you win \$2 for every \$1 you bet – plus your original stake back. If you bet \$10 on these odds, you’d win \$20 (plus your original \$10).

Odds can also be positive or negative. Positive odds (e.g. 4/1) show how much profit you could make from staking \$1; negative odds (-200) show how much you need to stake to win \$100 profit. For example:

-If a team has +350 moneyline odds, that means a \$100 bet would net you a profit of \$350 if they won
-If a team has -600 moneyline odds, that means you’d need to bet \$600 to clear a profit of \$100 if they won

## How to Convert Minus 310 Odds

Minus 310 odds means that you will have to bet \$310 to win \$100. This is also written as 1.03 in decimal form. To convert these odds to other forms, you can use an odds converter.

### Decimal Odds

Decimal odds, or European odds, are the simplest type of sports betting odds to understand. In decimal form, they express how much money you will win if you bet correctly. They are calculated by determining your stake and then adding it to your potential winnings. So if you bet \$10 on a team with decimal odds of 2.5 and they win, you will win \$25 (\$10 stake + \$15 in winnings).

To calculate decimal odds from other types of sports betting odds, use the following formulas:

American Odds
If the American odds are positive (e.g. +200), divide them by 100 and add 1. So +200 American odds become 2.0 decimal odds (200 ÷ 100 = 2 + 1 = 3).

If the American odds are negative (e.g. -200), divide 100 by the absolute value of the odds (i.e. 200) and add 1. So -200 American odds become 1/(100/200) + 1 = 1/2 + 1 = 1.5 decimal odds (-200 ÷ 100 = -2 + 1 = -1).

Fractional Odds
If the fractional odd is less than 2 (e.g. 8/5 or 4/1), divide your stake by the second number in the fractional odd and add that amount to your stake (+8 ÷ 5 = 1.6). So a \$10 stake at 8/5 would return \$26 (\$10 + 1.6 x \$10).

If the fractional odd is greater than 2 (e.g 3/1 or 9/2), divide your stake by the first number in the fractional odd and add that amount to your stake (+9 ÷ 3 = 3). So a \$10 stake at 9/2 would return \$30 (\$10 + 3 x \$10).

### Moneyline Odds

Converting odds from one format to another is a handy skill to have, especially if you intend on doing any sports betting. In the United States, most sportsbooks will use what’s called “American Odds.” These are the sort of odds that you’ll typically see in Las Vegas. To convert these Implied Probability Figures to probability, simply divide 100 by the number. So, -1200 would be 100/1200 = 0.08 = 8% chance of winning.

## Conclusion

Now that you know what minus 310 means in sports betting, you can use this knowledge to your advantage. If you see a line that is minus 310, you can be fairly certain that the favorite is going to win. However, don’t take this information for granted. Be sure to do your research and place your bets accordingly.
