At one time or another, it’s likely that you have placed a bet on a sports event. Whether it was placing a pre-game wager on the NFL, NCAA basketball, or even a game of poker, we’ve all been part of the gambling frenzy. And while we may not think about it very often, betting on sports is actually a form of gambling. Now, before you get too worried about all the math that goes into it, know that there are some simple steps you can take to calculate your sportsbook margin.

Doc’s Sports Service mentions that if you’ve never set foot in an actual sportsbook before or logged into an online sportsbook, the chances of you getting overwhelmed when you actually do is very high. When a novice sports bettor looks at the massive digital signage, they will see a bunch of numbers, both positive and negative, some two digits, some three digits. They also won’t have a clue what any of it means. The same can be said for the online sportsbooks. It looks like a massive spreadsheet with negative and positive numbers beside each teams’ name. That’s why it’s important to seek expert advice if you’re just getting started on your betting journey. In this article, we’ll explore what margins are and how to calculate them.

What are Sportsbook Margins?


Sportsbook margins are the percentage that a sportsbook pays out to bettors on any given sporting event. They can be found on websites like kumpulan situs judi bola terpercaya.

The general margin rules for online betting are as follows:

-The house edge is always 1%.

-The minimum bet is $5.

-The maximum bet is $2,500 per contest.

-There is no limit to the number of bets that can be placed on each contest.

-Bets must be placed through the sportsbook’s website or mobile app.

Margins vary from casino to casino and from sport to sport. The following are examples:

-Basketball: 100% (house edge = 0%)

-Football: 95% (house edge = 3%)

-NASCAR: 70% (house edge = 30%)

What is an Odds Spread?

An odds spread is simply the difference between the two sides’ opening betting amounts. Odds spreads can be used by sportsbooks to make money on each bet placed. In most cases, the house will require a certain amount of money as a margin before accepting any bets. This is why it is important to know what your odds spread is before placing any bets.

To calculate an odds spread, divide the line-kicker’s (LS) total payouts by the point-spread bettors’ total payouts. For example, if there are 10 bettors who opened with a -110 point spread and 1 bettor who opened with a +110 point spread, the LS would earn $1100 ($11000 line + $1000 point spread = $1100) while the PO would only earn $900 ($9000 line minus $1000 point spread = $900).

What is a Money Line?


A money line is a betting option where the bettor wagers whether the incoming point total (e.g. in basketball, points scored by both teams) will be greater than or less than the point spread. The betting line can be found on most sportsbooks and is usually displayed as either -110 (minus 110 points) or +110 (plus 110 points).

When making a money line bet, the bettor stakes whatever amount of money they feel comfortable with in order to win back their original investment if the team they choose loses by more points than the spread. Conversely, if the team they choose wins by more points than the spread, then they would make a profit based on their initial investment.

The margin between victory and defeat for a team is referred to as its “over/under” number and is found on most sportsbooks’ odds boards. For example, an over/under number for NBA games maybe 215. This means that if you place a bet on any NBA game with an over/under a number of 215, your bet will win if the San Antonio Spurs win by at least 5 points and lose if they lose by less than 5 points (i.e., if they score 203 or fewer points), but it will lose if they score more than 215 points.

What are Total Bets Placed?

A total bet is a type of bet that involves placing bets on all available races or sports events. Sportsbook margins are the difference between the amount wagered and the amount earned. Margins are important to understand because they can have a significant impact on your betting experience.

In general, sportsbooks will offer different margins for different wagers. For example, they may have higher margins for wagers involving more money or bigger odds. The margin displayed in a sportsbook’s lobby usually reflects the house edge (the percentage of profit taken by the bookmaker).

To calculate your own margin, divide the total bet amount by the total winnings. This gives you an approximation of how much of your bet was lost (house edge).

What is an Edge?


Edge refers to the difference between the betting odds and the house edge. The house edge is the percentage of money that a sportsbook loses on bets placed by its customers. Sportsbook margins are a key component in determining how profitable an individual bet will be. They can vary significantly from book to book, but they all have one common goal: to make as much money as possible while giving their customers a fair shake. Sportsbook margins come into play when calculating your potential profit or loss on any given wager.

In order to calculate margins, you first need to know two things: the point spread and the vigorish. The point spread is simply the number of points that each team is favored by in a particular game. For example, if Team A is favored by 3 points and Team B is favored by -5 points, then the point spread would be +3 points (Team A is ahead by 3 points). The vigorish is a charge that many sportsbooks add to their wagers in order to cover their operating costs. It’s also known as “the juice” or “the Spread.” The vigorish ranges from relatively low (for offshore books) to very high (for some inland books), but it always includes an up-front cost and goes toward ensuring that bettors get paid even if their team doesn’t win.

Once you’ve determined both the point spread and vigorish for a given game, you can calculate margins by subtracting the point spread from the vigorish. So, in the previous example, if Team A is favored by 3 points and Team B is favored by -5 points, then the margin would be -2 points (Team A is behind by 2 points). Margins are always expressed as a percentage of total wagers placed.

What are the Components of Sports Betting Margins?

There are three primary factors that affect sportsbook margins: customer activity, game action, and underlying odds.

Customer Activity – The more people who place bets in a given period, the higher the margin will be. This is because bookmakers earn a commission on each bet placed, which increases the overall take from their business.

Game Action – The number of points scored or lost during a game impacts margins significantly. A team that wins by a large margin will generally have higher margins than one that scores fewer points but rallies late in the game.

Underlying Odds – The amount of money wagered on each side of a bet impacts margins as well. A bettor who expects his team to win by 10 points will need to put down $100 to win $90 while someone who thinks they will lose by 10 points would only need to put down $10 to win $90 same-side wager (assuming perfect play).



When you bet on a sporting event, the house (or casino) always wins. This is because they are allowed to take a percentage of every bet made on each side of the game. The higher the margin, the more money that “the house” can make off your bets before you even see any winnings. To calculate sportsbook margins, simply divide the total amount wagered by the total amount won.
