Sports Betting Math
Most people who wish to put bets on sports are fans to begin with. It is not unheard of for a gambler to put some sports bets, especially during big games such as the Super Bowl or the NCAA basketball Final Four, however for the most part, sports bettors are sports lovers seeking to use their understanding of a sport or of a game’s players to earn a little additional money. Being a fan of a specific sport, a team, a college or skilled squad–these are all precursors to placing sports wager. Sports gambling can be a way for a fan to get in on the actions of the sport, with some thing more than self-respect in stake.
All gambling is math, even games of chance. If you understand the mathematics behind the sport, you understand the sport and will give yourself an advantage. For many games, like penny stocks or badly positioned blackjack stakes, are so bad that smart bettors earn their advantage by avoiding them completely. In sports betting, the math is more complex. Depending on your favorite game, you may have to think about things like bye weeks, underdogs, quarterback evaluations, and injuries with the same fervor other connoisseurs reserve for fancy winces.
So how hard is sports betting mathematics? The mathematics behind putting a winning bet is fairly complicated, however, the way to keep in front of the bookmaker is rather straightforward. Should you accumulate on 52.4% of your bets, then you’ll break even. We’ll have more information on this amount later, including why it takes more than 50 percent wins to break , but some general understanding about sports gambling and the numbers behind it.

Sports Betting Basics
The easiest way to demonstrate the math behind a sports bet is to make up an example. Let us say you and your buddy walk into a casino, each with $200 burning a hole in your pocket. There’s a big game on tonight, the Cowboys and the Redskins, so you wander into the sportsbook to check up on the most recent news about the game. As you’re sitting there, you see that the wagering board, with a few humorous numbers on it. It looks like this:
428 Cowboys +175
429 Redskins -4 -200 38
Some of this is simple enough to read. The Redskins -4 signifies the Redskins are favored to win and have to do this by at least 5 points for a wager on the’Skins to cover out. The next number (-200) is the moneyline, in this event the Redskins are a 2/1 favourite. The previous number (38) is that the total, the over/under of this anticipated number of points scored in the match.
More on Placing Sports Bets
Look at the over/under number, in this instance 38. If you or your buddy thinks this is going to be a particularly high or low scoring match, based on your knowledge of this group’s offenses and defenses, or information about a hurt player or poor playing requirements, you can set a bet on the total of points scored.
So just how is a man supposed to understand how to literally put down a sports wager? You Have to know three things:
#1 — the Kind of bet you want to make #2 — the number of the corresponding team you have chosen and
#3 — the amount you wish to bet Knowing all that beforehand provides the ticket writer the details he needs to write the ticket without having to bend over backwards to process your bet.
Tipping and Sports Betting
We haven’t even gotten into the meat of the sport mathematics yet, and we’re already talking about leaning the staff behind the window? Yep. Here’s the reason why.
If you place two $100 bets, and you win, you’ll amass $440. You need to think about leaving a tip around five percent of your winnings. Yes, that’s a $22 tip, but you just made a huge win, and surely you can spring for a twenty-spot for the guy who helped you win it. If you tip about the five per cent mark frequently, when you win, you are way more likely to find free drinks, which will be about all you are going to receive comp-wise at the sportsbook.
So, back to the basic math of sports betting. You and your friend, after much deliberation, decide to each place a $100 bet on your favourite team. What now?
To bet the Redskins using the point spread, your wager is called”placing the points” For your wager to cover off, the’Skins have to win by five or even more to cover the spread. Bear in mind, if the’Skins win exactly four, the game is a push, and both sides recover their bet. Another alternate is known as”taking the things” with the Cowboys. That usually means the Cowboys have to lose by less or three for your wager to win, or when the Cowboys win outright. So you and your friend go up to place your $100 bet, and you determine that the conventional right bet at any given bookie pays 11/10. That means you have to wager $110 if you would like to win $100. You and your friend pay the bookie $110 and sit down with beverages to watch your bets arrive in.
These are simple stakes. Deceptively since they make it look like the outcome of the football game is similar to the consequence of choosing marbles out of a bag. Put one black marble and two white marbles in a purse, pull one out randomly, and there’s your football match. After all, the chances are the same: 2/1 for white.
But we, as sports fans, know the math of a sporting event is much more complex. Sports bettors deeply involved in their own hobby will subscribe to weather bulletins from important cities that take part in their sport, making huge wagering decisions based on a few miles of wind in 1 direction or another. Then there is the unknown–does a player get hurt in the first quarter? Does weather become a variable? Is a particular participant”in the zone?”
How Do Bookies Make a Profit?
Just as we finish ruminating on the concept of the difficult math at play at the history of major sporting events, we’re going to turn right back towards the side of sports betting. Bookies make a gain because of vigorish. What is vigorish?
Look at the above example again. You and your buddy each paid $10 into the bookie to place your bet. That is what the standard 11/10 odds in sports gambling are all about. You wager the Cowboys and your buddy bet the Redskins, a total of 220 bet. The sportsbook must pay $210 into the winner, leaving a good $10 gain regardless of what happens on the football field. That $10 built-in profit is called the vigorish, and it is the final monkey wrench in the gears of sports gambling.
Obviously, sportsbooks will take over two stakes on any game, but this example is for simplicity’s sake. Taking a look at the total number of stakes on various games over the span of a week and adjusting the moneyline and other amounts is another way the bookie produces a profit. Fixing the chances a tiny percentage point in either way will affect the balance of beats and make the book more likely to turn a profit no matter what.
Essentially, a bookie is a person who holds on to money from bettors then pays them whenever they win and retains their money if they don’t. That’s what the occupation will be boiled down to its essence.
When a bookie sets chances for games, he’ll establish what bookies telephone an”over round” into his set of chances. Another slang term used for this particular formula is”the juice.” For the sake of simplicity, let’s consider a boxing game where both contenders are equally gifted, of equal prestige, etc.. Since they have an equal probability of winning, a more casual wager might be even cash. You put $20 on a single man; your friend puts $20 on the other. Whichever fighter wins awards that the bettor together with the total of 40.
Bookies don’t provide even cash like friends in a casual betting situation. In the aforementioned example, with just two equally matched boxers, a smart bookie will offer 5/6 odds for each. That way, a $10 winning wager would only return $8.30 plus your bet. What exactly does this do for the bookmaker? He could float an equal sum of money on both fighters, winning no matter which fighter actually wins. Should they choose $1,000 worth of stakes on one fighter and $1,000 on another, the bookie would require in $1,000 but only need to pay $830, to get a guaranteed $170 profit whatever the outcome.
Bookies look at the burden of their books all the time and adjust odds and other factors to be certain their books balance. Even though it isn’t possible to completely balance a book, bookies that move too far out on a single side run the risk of losing money, and losing money in gambling is the quickest way to find yourself in another industry. Each one of these factors are why bookies normally root for the underdog–too many favorites winning at a game with a brief season (such as the NFL) may cause a bookmaker to lose money, while a lot of upsets (like you generally see in college soccer ) is a guaranteed profit for the bookmaker.
The short answer here is that bookies making money has nothing whatsoever to do with your own gaming. It’s almost unheard of for one client to be permitted to put enough stakes to sink one book on his own. High rollers in sport gambling get special privileges concerning their maximum bet size, but these privileges often change with the bettor’s luck–maximums get increased after the bettor sees large losses and decreased (sharply) when the bettor starts to get lucky.
In short, a sportsbook’s profits are not necessarily impacted directly by how a single bet is called. Unlike casino games or slot machines, where it is you against the house, sports bettors fuel the bookmaker’s business and only rarely is a single bettor gambling from the bookie.
Sports Betting Odds
Remember at the start once we talked about the magic amount essential to guarantee a break-even week in sports betting? If you read about sports betting, you are going to hear this number repeated often: 52.4%. If a bettor can win 52.4percent of his stakes, he will break even. Where does that number come from?
If betting the spread, you receive odds of -110. Sometimes, sportsbooks will offer a -105 line for a promotion or to welcome new enterprise. But for the most part, if you’re betting the spread, you are getting -110.
We draw that 52.4% break even number right from the odds. -110 is equivalent to 11/10. That means in the event that you bet 21 games, then you’d have to acquire eleven of these and lose ten of these to split completely even. At -105, you would still need to win an astounding 51.2percent of the time merely to break even.
If you do not trust the basic mathematics behind this break-even principle, then look at another real life example. Let’s say that you get really into sports gambling after your Cowboys lotion the Redskins and you go home with a nice fat wallet. Then you bet on the next 10 Cowboys games, winning six times and losing four times.
This 60% gambling record (with the likelihood of -110 that is standard for against the spread bets in soccer ) will give you a profit of $160. Think about it–your $600 gain from your 6 winning stakes minus the $440 you dropped on losing bets leaves $160. It took you $1,100 to acquire $160, meaning you need to wager $6.87 to win $1 on average. So you find that the small differences between a 52.4% winning rate and a 60% winning rate–within people 7.3 percentage points lies hundreds of dollars in profit.
Now imagine instead that you lost one of these six winning bets, leaving you with a 50% gambling record. You spent a total of 1,100, won $500, and dropped $550. That means complete your 50% record drained your pocket by $50. That’s where the vigorish will get you. Not even winning half the time is good enough to break even in sport betting.
Professional Sports Bettors
Believe it or not, some people truly do bet on sports for a living. Maybe they work part time in a sportsbook or in certain other marginal job in the casino business, but there is a group of players who bet on sports due to their life’s work. With all the math swirling around in our minds following the last bit of the guide, it’s hard to imagine anyone wanting to do so for a living.
If you are aware that a 52.4% listing will mean you break , the easiest way to turn sports betting into a profession would be to bet enough to ensure a 53% winning record will bring in the kind of cash that you want to make.
Another instance. After your successful Cowboys experimentation, you decide to invest $10,000 in sports gambling through the first four months of the following football season. That $10,000 is set aside to acquire or lose in sportsbooks.
You plan on gambling on 160 games during your investment interval. You dream of a 55% winning record as your win-loss using a 55% winning record will provide you an 88-72 record. That is an expected profit of +8.8 units. How did we get to that number? To calculate your components, subtract the total of your losses (multiplied by 1.1 to include the vig) out of your wins and you’ll get your unit gain.
Placing $460 stakes on every one of these games, a number pulled from some quick and dirty math how much you could afford to bet in one week’s NFL play without blowing your bankroll, would result in a $4,048 profit if you maintain that 55% winning record. Turning $10,000 to $14,048 in just four weeks is an investment return of 40.48%. I dare you to ask your bank for that sort of return in your savings accounts.
But that is all assuming that you can pick the winner 55 percent of this time. Do your research, look into the records of professional sports gamblers. 55%, although not impossible, would place one of the elite sports bettors in the nation, or even the world.
Professional sports bettors have to fret about variance more than every other type of gambler. Working against the forces of variance means handling your bankroll over the duration of the season to avert the negative possibilities that could totally drain your wagering account. Professional sports bettors have the time and resources required to calculate these variances, and there are even a few pieces of software out there that may help you discover your ideal bet at the face of negative variance. But the bottom line is that professional sports bettors might dream of having a 55% winning album, simply because it ensures you are beating the house.
FURTHER INFO NOTE:
Pro bettors make their money on stakes that sportsbooks provide that give them even the slightest gaming advantage. The real key to becoming a lucrative sports bettor is having the ability to locate benefits, opportunities where the line a book is offering is exposed.
That is the reason why a lot of long-term sports bettors are mathematics freaks. Good sports bettors know statistics, particularly what are known as inferential statistics, though any greater math will help when it is time to place a wager.
Here is what a professional baseball bettor might do in his head. After looking over data from MLB (kept religiously by all kinds of writers, data archives( and magazines) between the years 2000-2010, he notices a particular statistic pop out. For example: when the home team begins a left-handed pitcher daily following a loss, that group wins 59 percent of their time. Good sports bettors can do this kind of math in their mind or quite fast on paper. From that bit of advice comes a brand new gaming concept –look for sport scenarios that mirror the above example and bet on them. That means he will only bet games where the home team starts a left-handed pitcher the day following a loss. Can he simply leap in and start gambling based on this back of the napkin math? No way. More statistical analysis is required–he may discover that this is a fluke for that specific decade and isn’t a trustworthy statistics, or he can find a much more valuable bet based upon his original theory.
Professional sports bettors also keep near-obsessive recordings of their stakes. Evidently, no advantage in sports gambling lasts more than one game. Taking appropriate records will even help you examine theories, like the preceding one about left-handed pitchers and losses. Without taking good documents, no sports bettor’s bankroll will last quite long.
What Is a Good Record for Sports Bettors
So, in the close of the day, what would you call a”good” document for a sports bettor? Most casual gamblers searching into sports betting see a professional advertising his 1100-900 listing and shake their head a bit. How could such an abysmal record be something to be proud of? That is a 55% winning percentage, and it suggests to people in the know that this bettor is actually turning a profit putting bets on sports. A good record to get a sports bettor is any record equal to or bigger than 52.4%, because that number or anything greater means you’re not losing money. A 53% winning record, while not impressive on paper, means you’re really beating the sportsbook and putting cash back in your pocket. Ask your buddies that play the slots or play online poker how often they wind up putting cash back into their pocket.
A -110 wager, standard for spread bets in the NFL, gives the house a built-in benefit of 10%. It means that even if you do win, and you line up to collect your $100, a few sucker supporting you just spent $10 to hand the casino $100.
A fantastic listing for sport bettors is any recording that ensures they at least break-even. If you gamble 16 games this NFL season and you won 9 and lost 7, you likely made money. And taking money away from a casino is always something to be proud of.
