If you bet on sporting events, you must be able to read odds and understand what they mean. Furthermore, you need to quickly calculate the potential winnings for different bets, especially if the odds are changing while the event unfolds. Odds tell you the likelihood that an event will occur (a team wins, a boxer makes it a certain round) and how much will be paid out if you win. There are, however, multiple ways to convey this information.


Understand that negative odds indicate how much money your must spend to make $100. When betting on the favorite, you take less risk, and thus earn less. When betting on a favorite, the moneyline is the amount of money you need to spend to make $100 profit. In the previous example, in order to make $100 of profit betting for the Cowboys, you would need to spend $135. Like positive odds, you earn back your bet when winning.
The favorite team or player on the moneyline is the team that’s expected to win. This side of the bet usually listed with a minus (-) sign. The underdog team or player on the moneyline is the team that’s expected to lose. This side of the moneyline is usually listed with a plus (+) sign. These signs signify how either side of the wager will pay. The minus side will pay less than original wager while the plus side will pay more than the original wager.

For each NFL game the oddsmakers set a number of points in which the favored team is favored by. Bettors can then either choose for the favored team to win by more than the number of points set, or bet on the underdogs to lose by less than the number of points they are underdogs by or win the game straight up. For example, the spread could be set on the favored team at 6.5 points. This would mean in order for a bet on the favored team on the spread to win they would need to win by more than 6.5 points (7 or more) in order to win the bet. It also means that a bet on the underdog team would win if the underdogs lost by less than 6.5 points (6 or less) or won the game outright.

So to solve the first fraction for the Heat, we do 13 divided by 20 and get 0.65. Let’s look at our calculations for the $10 bet and the $250 bet. If we bet $10, we multiply our solved fraction of 0.65 by $10 and get $6.50. This is our correct profit! If we bet $250, we multiply our solved fraction of 0.65 by $250 and get $162.50. This is out correct profit!


Betting on sporting events has long been the most popular form of spread betting. Whilst most bets the casino offers to players have a built in house edge, betting on the spread offers an opportunity for the astute gambler. When a casino accepts a spread bet, it gives the player the odds of 10 to 11, or -110. That means that for every 11 dollars the player wagers, the player will win 10, slightly lower than an even money bet. If team A is playing team B, the casino is not concerned with who wins the game; they are only concerned with taking an equal amount of money of both sides. For example, if one player takes team A and the other takes team B and each wager $110 to win $100, it doesn’t matter what team wins; the casino makes money. They take $100 of the $110 from the losing bet and pay the winner, keeping the extra $10 for themselves. This is the house edge. The goal of the casino is to set a line that encourages an equal amount of action on both sides, thereby guaranteeing a profit. This also explains how money can be made by the astute gambler. If casinos set lines to encourage an equal amount of money on both sides, it sets them based on the public perception of the team, not necessarily the real strength of the teams. Many things can affect public perception, which moves the line away from what the real line should be. This gap between the Vegas line, the real line, and differences between other sports books betting lines and spreads is where value can be found.
One way to make money from sports betting is to open an account at an online betting site and take advantage of their sign up bonus. This gives you extra money to wager with, and since point spreads are so straightforward, it can be relatively easy to meet the associated wagering requirements and still come out ahead. Repeating this process at multiple betting sites will maximize your potential returns! We just ask that you please stick with reputable sites, like any of the ones that we recommend.
As you can see, the public seems to think that Florida is going to win this game by more than seven points. If the game started now, the sportsbook would stand to lose a lot of money if Florida did in fact win by more than seven points. They would stand to make a lot of money if Florida lost or won by less than seven points. Regardless of how the sportsbook thinks the game will go, they are not in the business of gambling. They want to guarantee profit as often as they can.
The last format we want to look at is fractional odds. Personally, we aren’t a huge fan of fractional odds because they’re the most challenging to work with. The formula is almost the same as with decimal odds, but it gives your profit instead of total money returned. It also requires you to solve a fraction, which may be a nightmare for a lot of people. Regardless, we are going to walk you through how to do it with the same bet we’ve been working with.

Remember, these calculations are for your profit. Profit is different than the total money returned that you will get from the sportsbook. If you correctly bet the Falcons to win, the sportsbook will return you $340. This will be your $240 in profit as well as your $100 bet that you made. Make sure that you pay attention to this when working with these numbers because we see people get confused all the time as different sportsbooks will give you different numbers.
The most important takeaway is the actual pointspread, which is seven points in this example. The plus sign is always in front of the spread for the underdog and the minus sign is used to signify the favorite. Next to the pointspread in this example is (-110). This number reflects the actual commission (or juice) that the sportsbook is charging to book this bet. If you wager $100 on New England as the favorite and the Patriots go on to win my more than seven points, you would win $100. If they won by fewer than seven points or lost the game outright, you would owe this betting outlet $110. If New England wins by exactly seven points, the bet is considered to be a PUSH and no money exchanges hands. You only pay the 10 percent commission on losing bets.
Spreads are frequently, though not always, specified in half-point fractions to eliminate the possibility of a tie, known as a push. In the event of a push, the game is considered no action, and no money is won or lost. However, this is not a desirable outcome for the sports book, as they are forced to refund every bet, and although both the book and its bettors will be even, if the cost of overhead is taken into account, the book has actually lost money by taking bets on the event. Sports books are generally permitted to state "ties win" or "ties lose" to avoid the necessity of refunding every bet.
Apply the money line. It's easiest to think of money lines in relation to $100. A minus sign means you have to bet that much money in order to win $100; a plus sign means that a $100 bet will return that much money. If you bet on Chicago at -110, you'll have to wager $110 in order to get back $100 (plus your original $110). If you bet on Detroit at +145, then a $100 bet will give you $145 (plus your original $100).
Remember that every spread still has a moneyline attached to it. While that might be a bit confusing, all that refers to is the cost of betting the spread; not how the outcome will be decided. For example, if someone says to you that “the Patriots are laying three points but I have low juice, so my moneyline is -104”, what they are referring to is the price of betting the spread. That merely means that they are betting the spread but the moneyline attached to betting that spread is -104.
In the UK and some other European countries the profit from spread betting is free from tax. The UK and some other European countries tax authorities designate financial spread betting as gambling and not investing, meaning it is free from capital gains tax and stamp tax, despite the fact that its regulated as a financial product by the Financial Conduct Authority in the UK. Most traders are also not liable for income tax unless they rely solely on their profits from financial spread betting to support themselves. The popularity of financial spread betting in the UK and some other European countries, compared to trading other speculative financial instruments such as CFDs and futures is partly due to this tax advantage. However, this also means any losses cannot be offset against future earnings for tax calculations.
As an example, let’s consider a matchup between the Indianapolis Colts and the Cincinnati Bengals. In our scenario, the Bengals are the home team, which means they will be listed last and the Colts, as the visitors, will be on the odds slip first. If Indy’s rotation number is 101, then Cincy’s rotation mark would be 102. When you place a bet live at a Vegas sportsbook or over the phone, you would say the number of the team on which you want to wager and not the name.

If you were correct though but getting paid at the sportsbooks rate, you would lose the bet 55.6 times (-$5560) and win the bet 44.4 times (44.4 x $250 = $11,100). You would profit over $5,000 for betting on bets that you thought you were going to lose! This is finding value. Value bets are great as a part of a long term winning strategy and are the key to conquering the “simple” moneyline/win bets.

"Grand Salami" is where you bet on the total number of listed occurrences, such as total goals or run, Happening during a collection of events. All relative events must be completed for bets to stand except for the outcomes of which have been decided prior to the abandonment and could not possibly be changed regardless of future events, which will be settled according to the decided outcome.
For example, in a cricket match a sports spread betting firm may list the spread of a team’s predicted runs at 340 – 350. The gambler can elect to ‘buy’ at 350 if they think the team will score more than 350 runs in total, or sell at 340 if they think the team will score less than 340. If the gambler elects to buy at 350 and the team scores 400 runs in total, the gambler will have won 50 unit points multiplied by their initial stake. But if the team only scores 300 runs then the gambler will have lost 50 unit points multiplied by their initial stake.
Let’s say the sportsbook has a series of bets that are all +250. You think in reality that the bets should actually be +125 and that the bet is not as big of an underdog as the sportsbook thinks. This means that you think you deserve $125 for every $100 bet that wins but the sportsbook is going to pay $250. Even though you think that the bet is still supposed to lose, you should make this bet.

We’ll start by posting a question. If you think that one team will beat another team and you are almost certain of it, should you make that bet every single time? If you answered yes, then you really need to start learning this concept. What we neglected to tell you was that the team you wanted to bet on have odds of -2000. This means that for a $100 bet, you will get a profit of $5.

A Parlay is a wager which combines several legs in a wager where the winnings from each selection roll onto the next. For a Parlay to be successful, all individual legs in the Parlay need to be winning selections. In the event of a tie in one of your selections in a parlay, the parlay is reduced to the next lowest number of teams. For example, if you have a 4 team parlay and one of the selections is a tie (only on 2 way markets), the leg would be considered a "push". In this instance, the 4 team parlay would then become a 3 team parlay and would be settled at reduced odds to reflect a winning 3 team parlay.
This means that the people betting the big bucks are going to end up shifting the line considerably. A lot of times, you will see a moneyline released, and then it will quickly shift. Usually, this is a skilled big bettor taking advantage of what they think is an opportunity. Ideally, you’ll want to jump on bets before these skilled bettors get ahold of it.
It’s common knowledge among bettors that the online gambling industry pays close attention to Las Vegas Sports Consultants, a private company that handles the odds for casinos and newspapers. But the totals I set have to reflect our customers’ preferences for betting the over or under on certain teams in certain situations. Also, because LVSC lines are published early, I have to keep on top of injuries and potential changes in coaching strategy leading up to the game in question before I release any totals. This is doubly important in basketball, where pace determines how many shots will be taken in 48 minutes.
We need to figure out how much profit we will get per dollar we are going to bet and then multiply that by how many dollars we are going to bet. If we divide the moneyline number by 100, it will tell us how much profit we will get for every $1 we bet. So, 145/100 = $1.45. For every $1 we wager, we will get paid $1.45 in profit for a correct prediction.

Technically, probability should always be a number between 0 and 1. It's often expressed as a percentage though, which makes things easier for the purposes of betting. 0.7059 converted into a percentage (i.e. multiplied by 100) gives us 70.59%. What this means is that the odds suggest the Celtics have a 70.59% chance of winning. If we believe the Celtics have an even greater chance of winning, then we should back them at odds of -240.
The moneyline is different. First, with the moneyline whichever team wins the game pays out. There’s no giving or taking away of points. How do the bookies even the playing field with the moneyline? They do it by making bettors wager more on the favorite to win less and allowing them to bet less to win more on the dog. The favorite is posted with a minus sign and a number. That number represents the amount of cash that has to be wagered in order to win $100. The underdog, on the other hand, is listed with a plus sign in front of a number. That number shows how much a bettor wins when they bet $100.
When you bet on the money line, you are betting on one side to simply win. Any time you see a money line, the minus sign (-) indicates the favorite while the plus sign (+) indicates the underdog. For example: Chicago Bears –240 vs. Minnesota Vikings +210. Using $100 as the base, it will take $240 wagered on the Chicago Bears to win $100. For a bettor wagering on the underdog Minnesota Vikings in this scenario, $100 will win $210. 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.

Here’s a less extreme example. Let’s say that Fighter A is fighting Fighter B and you think that Fighter A is going to annihilate Fighter b. Like you don’t even think it’s going to be close. Let’s say you decide that you would be willing to bet even if the odds were -400 on Fighter A. You’d only be getting $25 back on your bet, but that’s what you think is fair.

Shopping betting lines is one of the most important things you can do when betting point spreads in basketball. While the majority of sportsbooks will have the same line, it's fairly common that you can find lines that are a half or full point different. This can have a huge impact on your bottom line. If you don't think a half point or one full point makes that big of a difference, just ask anyone who has bet sports for a while. They will inform you that getting an extra half point is like winning the sports betting lottery.
Score three is usually the one that confuses people. Remember, when betting on point spreads, the favorite has to win by more than the number of points they are projected to win by. The underdog can lose the game, and you can still win your bet as long as they don't lose by more points than they are spotted. In the above example, if you were to bet on the Chargers at +3, you can imagine that like you have three bonus points to play with. You can lose by one point or by two points and still win the bet. If you bet the Chargers at +3 and lose by three points, it is a tie.
Identify the type of line you are looking at. All online sports books offer you the chance to have your lines in an "American" or "Money line" version. If I were you, I would use this as my standard. An "American" line uses either a + or - before a number to indicate odds. So a -120 and a +120 are two very different odds on a team… I will explain the differences shortly. Two other less common variations exist: decimal odds and fractional odds.

Simply, bigger returns. On a point spread bet you would usually have to spend $105 or $110 to win $100. If you bet on the moneyline you may instead only have to spend $50, or even less, to win $100. You won't win as often, of course, because the underdog not only has to cover the spread, but it actually has to win the game outright. Upsets happen, though, and good handicapping will often isolate situations where the likelihood of an upset exceeds the risk of the bet. This is especially relevant in the NBA because the number of games, and the possibility for even the best teams to have a bad night mean that major upsets are far from rare and can be very profitable.
There are four elements to the moneyline bet that you can see here. The first column is just an identifier of which bet is which for the sportsbook. When you place your bets, you can tell the sportsbook you want to bet on the Eagles to win or that you want to take bet 055. This number has nothing to do with the actual game and is just a code for the sportsbook to keep their bets organized.

We go in depth on this in the advanced guide on understanding value that we referenced earlier, but we will give you a brief intro on it here. If you’re able to calculate the percentage chance that you have to win in order to break even, and you can figure out the percentage chance that you think you’re going to win the bet, you can figure out very quickly if there is value.
Let’s say that a ton of bets pour in on the Mavericks. In order to encourage more bets on the Celtics and even things out, they might move the line to 5 ½. This means that a bet on the Mavericks would now win only if they won by more than 5 ½ points instead of 4 ½. This would discourage more people from betting on the Mavericks, as they would have to perform much better to get you the victory.
