Sports Betting Math
Most people who want to put bets on sports are lovers to start with. It isn’t unheard of for a gambler to place some sports stakes, particularly during big games such as the Super Bowl or the NCAA basketball Final Four, however for the most part, sports bettors are sports lovers looking to utilize their knowledge of a sport or even of a game’s players to make a little extra cash. Being a fan of a particular sport, a staff, a school or skilled squad–all of these are precursors to putting sports wager. Sports betting can be a way for a lover to get in on the actions of this game, with something more than self-respect in stake.
All gambling is mathematics, even games of chance. If you understand the math behind the sport, you understand the sport and will give yourself an advantage. For many games, like penny slots or badly positioned roulette bets, are so bad that smart bettors make their advantage by avoiding them altogether. In sports betting, the mathematics is more complex. Depending on your favourite game, you may have to consider matters like bye weeks, underdogs, quarterback ratings, and injuries with the identical fervor other connoisseurs reserve for fancy winces.
So how hard is sports gambling math? The mathematics behind putting a winning wager is fairly complicated, however, the way to keep in front of the bookmaker is rather simple. Should you accumulate on 52.4% of your bets, then you are going to break even. We’ll have more details on that number after, for example why it takes over 50 percent wins to break even, but some general understanding about sports betting and the figures behind it.

Sports Betting Basics
The simplest way to demonstrate the math behind a sports bet is to make up an illustration. Let us say you and your friend walk into a casino, each with $200 burning a hole in your pocket. There is a big game on tonight, the Cowboys and the Redskins, so you wander in the sportsbook to check up on the latest news about the sport. As you’re sitting there, you see the wagering board, with some humorous numbers on it. It looks like this:
428 Cowboys +175
429 Redskins -4 -200 38
Some of this is easy enough to read. The Redskins -4 means the Redskins are preferred to win and have to do so by at least 5 points for a wager on the’Skins to pay out. The next number (-200) is the moneyline, in this case the Redskins really are a 2/1 favorite. The previous number (38) is the complete, the over/under of the expected number of points scored in the match.
More on Placing Sports Bets
Look at the over/under amount, in this instance 38. In the event that you or your friend thinks this is going to be a particularly low or high scoring match, based on your knowledge of the group’s offenses and defenses, or information about a hurt participant or poor playing requirements, you can set a bet on the total of points scored.
So how is a man supposed to know how to literally put down a sports wager? You need to know three things:
#1 — the type of wager you want to create #2 — the amount of the corresponding group You’ve chosen and
#3 — the amount You Would like to bet Knowing everything ahead provides the ticket writer the details that he wants to write the ticket without needing to bend over backwards to process your wager.
Tipping and Sports Betting
We have not even gotten into the meat of the sports math yet, and we’re already talking about leaning the staff behind the window? Yep. Here’s why.
If you place two $100 bets, and you win, you are going to amass $440. You need to consider leaving a tip about five percent of your winnings. Yes, that’s a $22 tip, but you just made a huge triumph, and certainly you can spring for a twenty-spot for the guy who helped you win it. Should you tip around the five percent mark regularly, when you win, then you’re way more likely to get free drinks, which will be about all you are going to get comp-wise at the sportsbook.
Soback to the simple math of sports betting. You and your buddy, after much deliberation, decide to each place a $100 wager on your favourite team. What now?
To bet the Redskins using the point spread, your wager is known as”placing the points” For your wager to cover off, the’Skins need to win by five or more to cover the spread. Remember, if the’Skins win by exactly four, the game is a push, and either side recover their bet. Another alternative is called”taking the points” with the Cowboys. That usually means the Cowboys must lose by three or less for your bet to win, or when the Cowboys win outright. So you and your buddy go up to put your $100 wager, and you determine that the standard straight bet in any bookie pays 11/10. That means you have to bet $110 if you want to win $100. You and your buddy pay the bookie $110 and sit down with beverages to watch your stakes arrive in.
These are deceptively simple stakes. Deceptively since they make it look like the outcome of the football game is like the consequence of picking marbles from a bag. Put one black marble and 2 white marbles in a bag, pull one out at random, and there is your soccer game. After all, the odds are exactly the same: 2/1 for white.
But we, as sports fans, know the math of a sporting event is a whole lot more complicated. Sports bettors deeply involved in their hobby will join to weather bulletins from important cities which take part in their sport, making huge wagering decisions based on a couple of miles of wind in one direction or another. Then there’s the unknown–does a player get hurt in the first quarter? Does weather turned into a variable? Is a particular player”in the zone?”
How Do Bookies Make a Profit?
As we finish ruminating on the concept of the difficult math at play in the history of important sporting events, we are going to turn back towards the simpler side of sports betting. Bookies make a profit because of vigorish. What’s vigorish?
Examine the above example . You and your friend each paid $10 into the bookie to put your bet. That’s what the conventional 11/10 odds in sports betting are all about. You bet that the Cowboys and your buddy bet the Redskins, a total of 220 bet. The sportsbook must pay $210 into the winner, leaving a nice $10 profit regardless of what happens on the football field. That $10 built-in profit is called the vigorish, and it’s the last monkey wrench in the gears of sport betting.
Obviously, sportsbooks are going to take over two stakes on any sport, but this example is for simplicity’s sake. Looking at the total number of stakes on various games over the span of a week and adjusting the moneyline and other numbers is another manner in which the bookie produces a profit. Fixing the odds a tiny percentage point in either way will affect the balance of beats and make the book more likely to develop a profit no matter what.
Basically, a bookie is someone who holds on to cash from bettors subsequently pays them if they win and keeps their money if they don’t. That is what the occupation is boiled down to its essence.
When a bookie sets odds for games, he will build what bookies call an”over around” into his group of chances. Another slang term used with this formulation is”the juice.” For the sake of simplicity, let’s look at a boxing match where the two contenders are equally talented, of equal prestige, etc.. Since they have an equal chance of winning, a casual wager might be even cash. You place $20 on one guy; your friend puts $20 on another. Whichever fighter wins awards the bettor together with the total of 40.
Bookies do not provide even cash like friends in a casual betting situation. In the aforementioned example, with just two evenly matched boxers, a smart bookie will offer 5/6 chances for each. That way, a 10 winning wager would just return $8.30 plus your bet. What exactly does this do for the bookmaker? He can float an equal sum of money on both fighters, winning regardless of which fighter actually wins. If they take $1,000 worth of stakes on a single boxer and $1,000 on the other, the bookie would take in $1,000 but just have to pay $830, to get a guaranteed $170 gain whatever the outcome.
Bookies consider the burden of the books all of the time and adjust odds and other factors to be sure their books equilibrium. Even though it isn’t feasible to completely balance a book, bookies that go too far out on a single side run the risk of losing money, and losing money in betting is the fastest way to find yourself in a different industry. Each one these variables are why bookies generally root for the underdog–too many favorites winning in a sport with a brief season (such as the NFL) may cause a bookmaker to eliminate money, though a bunch of upsets (like you normally see in college football) is a guaranteed gain for the bookmaker.
The brief answer here is that bookies making money has nothing at all to do with your own gaming. It’s almost unheard of for one customer to be allowed to put enough stakes to sink one book on his own. High rollers in sports betting get exceptional privileges concerning their maximum bet size, but these privileges often change with all the bettor’s luck–maximums get increased after the bettor sees large losses and decreased (sharply) when the bettor starts to get blessed.
In short, a sportsbook’s profits aren’t necessarily impacted directly by the way a single bet is called. Unlike casino games or slot machines, where it’s you against the house, sports bettors gas that the bookmaker’s company and only rarely is an individual bettor betting from the bookie.
Sports Betting Odds
Remember at the start once we talked about the magic amount necessary to guarantee a break-even week in sports gambling? If you read about sports betting, you’ll hear this amount repeated often: 52.4%. If a bettor can acquire 52.4percent of his bets, he’ll break . Where does this number come from?
When betting the spread, you get odds of -110. Sometimes, sportsbooks will provide a -105 line for a marketing or to welcome new business. But for the most part, if you are betting the spread, you’re getting -110.
We draw that 52.4% break even number right from the odds. -110 is equal to 11/10. That means in the event that you bet 21 games, you would need to acquire eleven of them and lose ten of these to break completely even. At -105, you would still need to acquire an astounding 51.2% of the time just to break even.
If you don’t trust the basic math behind this break-even principle, then look at another real life example. Let us say you get into sports betting after your Cowboys lotion the Redskins and you go home with a great fat wallet. You then bet on the next 10 Cowboys games, winning six times and losing four occasions.
This 60% betting record (with the odds of -110 that’s traditional for against the spread stakes in soccer ) will give you a gain of $160. Think about it–your $600 gain from your 6 winning stakes minus the $440 you lost on losing bets leaves $160. It required you $1,100 to acquire $160, which means that you need to wager $6.87 to acquire $1 on average. So you find the tiny differences between a 52.4% winning rate and a 60% winning speed –inside those 7.3 percentage points lies countless dollars in profit.
Now imagine instead that you misplaced one of those six winning bets, leaving you with a 50% betting record. You invested a total of 1,100, won $500, and dropped $550. That means overall your 50% listing drained your pocket by $50. That is where the vigorish will get you. Not even winning half the time is good enough to break even in sports betting.
Professional Sports Bettors
Believe it or not, some folks really do bet on sports for a living. Maybe they work part time at a sportsbook or in some other marginal job in the casino industry, but there’s a group of players who wager on sports for their life’s work. With all the mathematics swirling around in our heads after the last piece of the article, it is difficult to imagine anyone attempting to do this for a living.
If you are aware that a 52.4% record will signify you break even, the simplest way to turn sports betting to a career is to wager enough so that a 53% winning record will bring in the type of cash you want to make.
Another instance. Following your successful Cowboys experimentation, you decide to spend $10,000 in sport betting over the first four months of the following football season. That $10,000 is set aside to win or shed sportsbooks.
You plan on gambling on 160 games throughout your investment interval. You dream of a 55% winning album because your win-loss using a 55% winning record will provide you an 88-72 record. That’s an expected gain of +8.8 units. How did we get to that amount? To calculate your units, subtract the total of your losses (multiplied by 1.1 to include the vig) from your wins and you are going to get your unit profit.
Placing $460 stakes on each of these games, a number pulled from some quick and dirty math how much you can afford to bet in one week’s NFL play without blowing your bankroll, would result in a $4,048 gain if you keep this 55% winning record. Turning $10,000 into $14,048 in just four months is an investment yield of 40.48%. I dare you to ask your lender for that sort of return in your savings account.
But that is all assuming that you can pick the winner 55% of this time. Do your research, check into the records of professional sports gamblers. 55%, while not impossible, would place you among the elite sports bettors from the nation, or even the world.
Professional sports bettors have to fret about variance over every other kind of gambler. Working against the forces of variance means managing your bankroll over the course of the season to avert the negative possibilities that may totally empty your wagering account. Professional sports bettors have the resources and time necessary to compute these variances, and there are a few pieces of software out there which may help you discover your ideal stake in the face of negative variance. But the most important thing is that professional sports bettors would dream of having a 55% winning album, only because it ensures you’re beating the house.
FURTHER INFO NOTE:
Professional bettors make their money on stakes that sportsbooks offer that give them even the smallest betting advantage. The real key to becoming a profitable sports bettor is being able to locate advantages, chances where the line a publication is offering is vulnerable.
That is why a lot of long-term sports bettors are math freaks. Good sports bettors know statistics, especially what are known as inferential statistics, though any greater math can help when it is time to put a wager.
Here’s what an expert baseball bettor can do in his head. After looking over statistics from MLB (kept religiously by all kinds of bloggers, data archives( and magazines) involving the years 2000-2010, he notices a specific statistic pop outside. For instance: when the home team starts a left-handed pitcher daily after a reduction, that group wins 59% of the time. Superior sports bettors can do this kind of mathematics in their head or quite fast on paper. From that piece of advice comes a new gaming concept –look for game scenarios that mirror the above example and bet on them. Meaning he will only bet games where the home team begins a left handed pitcher daily following a loss. Does he just jump in and start gambling predicated on this back of the napkin math? No way. More statistical analysis is required–he may find that this is a fluke for that particular decade and is not a trusted statistics, or he may discover a much more advantageous bet based on his original concept.
Pro sports bettors also keep near-obsessive recordings of their stakes. Evidently, no edge in sports gambling lasts more than one game. Taking appropriate records will even help you examine concepts, like the above one about left-handed pitchers and losses. Without taking good documents, no sports bettor’s bankroll will last very long.
What Is a Good Record for Sports Bettors
So, at the close of the day, what would you call a”good” document for a sports bettor? Most casual gamblers looking into sports gambling see a pro advertising his 1100-900 listing and shake their head a bit. How could such an abysmal record be something to be proud of? That’s a 55% winning percentage, and it suggests to people in the know this bettor is in fact turning a profit putting bets on sports. A fantastic record for a sports bettor isn’t any record equivalent to or larger than 52.4%, because that number or anything greater means you’re not losing money. A 53% winning record, although not impressive on paper, means you’re actually beating the sportsbook and putting money back in your pocket. Consult your friends that play the slots or play online poker how often they end up putting cash back into their pocket.
A -110 bet, regular for spread bets in the NFL, gives the house a built-in benefit of 10%. It means that even in the event that you do win, and you line up to collect your $100, some sucker supporting you only spent $10 to hand the casino $100.
A fantastic listing for sport bettors is any recording that ensures that they break-even. Should you bet 16 games this NFL season and you also won 9 and lost 7, then you likely made money. And taking money from a casino is always something to be proud of.
