Sports Betting Math
Most people who want to put bets on sports are lovers to begin with. It is not unheard of for a gambler to put some sports stakes, particularly during big games like the Super Bowl or the NCAA basketball Final Four, but for the most part, sports bettors are sports fans seeking to use their knowledge of a sport or even of a game’s players to earn a little additional money. Being a fan of a specific sport, a staff, a school or professional squad–these are all precursors to putting sports wager. Sports gambling can be a means for a fan to get in on the actions of the sport, with something more than self-respect in stake.
All gambling is mathematics, even games of chance. If you understand the math behind the game, you understand the sport and will give yourself an edge. For many games, like penny slots or even badly positioned blackjack stakes, are so bad that smart bettors earn their benefit by avoiding them altogether. In sports betting, the math is more complex. Depending upon your favourite game, you might need to think about matters like bye weeks, underdogs, quarterback evaluations, and harms with the same fervor additional connoisseurs book for fancy winces.
So how hard is sports betting mathematics? The mathematics behind placing a winning bet is rather complicated, but the best way to keep in front of the bookmaker is quite straightforward. If you accumulate on 52.4percent of your bets, you are going to break even. We’ll have more information on this amount after, including why it requires more than 50% wins to break , but first 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 would be to make up an example. Let’s say you and your friend 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 drift into the sportsbook to check up on the most recent news about the game. While you’re sitting there, you find 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 simple enough to read. The Redskins -4 means the Redskins are favored 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 that the moneyline, in this event the Redskins really are a 2/1 favourite. The last number (38) is that the total, the over/under of this anticipated number of points scored in the game.
More on Placing Sports Bets
Look at the over/under number, in this case 38. In the event that you or your buddy thinks this is going to be a particularly low or high scoring game, based on your understanding of this group’s crimes and defenses, or advice about a hurt participant or poor playing conditions, you can place a wager on the total of points scored.
So how is a man supposed to understand how to literally put down a sports bet? You need to know three things:
#1 — the Kind of wager you want to make #2 — the number of the corresponding group You’ve chosen and
#3 — the amount You Would like to wager Knowing everything beforehand provides the ticket writer the details he needs to write the ticket without having to bend over backwards to process your wager.
Tipping and Sports Betting
We haven’t even gotten into the meat of this sport math yet, and we’re talking about leaning the team behind the window? Yep. Here’s why.
If you put two $100 bets, and you win, then you are going to collect $440. You should 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 around the five per cent mark regularly, when you win, then you are way more likely to get free drinks, which is about all you’re likely to get comp-wise in the sportsbook.
Soback to the basic math of sports gambling. You and your buddy, after much deliberation, decide to each area a $100 bet on your favourite team. What now?
To bet the Redskins utilizing the point spread, your wager is known as »placing the points. » For your wager to cover off, the’Skins have to win five or more to cover the spread. Remember, if the’Skins win by exactly four, the game is a push, and either side recoup their wager. 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 bet to win, or if the Cowboys win outright. So you and your friend go up to put your $100 wager, and you determine that the conventional straight bet at any bookie pays 11/10. This 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 stakes come in.
These are deceptively simple bets. Deceptively because they make it resemble the results of the soccer game is similar to the consequence of picking marbles out of a bag. Put one black marble and 2 white marbles in a purse, pull one out at random, and there is your soccer match. In the end, the chances are the same: 2/1 for white.
But we, as sports fans, know that the mathematics of a sporting occasion is a whole lot more complicated. Sports bettors profoundly involved in their hobby will subscribe to weather bulletins from major cities which take part in their game, making enormous wagering decisions based on a few 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 factor? Is a specific player »in the zone? »
How Do Bookies Make a Profit?
Just as we end ruminating on the concept of the difficult mathematics at play in the background of important sporting events, we are going to turn back towards the simpler side of sports betting. Bookies make a gain due to vigorish. What is vigorish?
Look at the above example . You and your friend each paid $10 to the bookie to put your bet. That’s exactly what the standard 11/10 odds in sports gambling are all about. You bet that the Cowboys and your buddy bet the Redskins, a total of 220 bet. The sportsbook must pay $210 to the winner, leaving a good $10 profit regardless of what happens on the football field. That $10 built-in profit is called the vigorish, and it is the last monkey wrench in the gears of sports betting.
Obviously, sportsbooks will take over two stakes on any sport, but this example is for simplicity’s sake. Taking a look at the whole number of bets on different games over the course of a week and adjusting the moneyline and other amounts is just another manner in which the bookie makes a profit. Adjusting the chances a very small percentage point in either way will affect the equilibrium of beats and make the publication more likely to develop a profit no matter what.
Essentially, a bookie is someone who holds on to cash from bettors subsequently pays them whenever they win and keeps their money if they don’t. That’s what the job will be boiled down to its essence.
When a bookie sets odds for matches, he’ll establish what bookies call an »over around » to his set of chances. Another slang term used for this formula is »the juice. » For the sake of simplicity, let us consider a boxing game where the two contenders are equally talented, of equivalent prestige, etc.. Since they both have an equal probability of winning, a more casual wager may be even money. You put $20 on a single guy; your buddy puts $20 on another. 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 above example, with two evenly matched fighters, a wise bookie provides 5/6 chances for each. This way, a $10 winning wager would only return $8.30 plus your stake. What does this do to the bookmaker? He could float an equal amount of money on both fighters, winning no matter which fighter actually wins. If they choose $1,000 worth of stakes on a single fighter and $1,000 on the other, the bookie would require at $1,000 but only need to pay out $830, for a guaranteed $170 profit whatever the outcome.
Bookies consider the weight of their books all of the time and fix odds and other factors to make sure their books equilibrium. Though it isn’t possible to completely balance a publication, bookies which move too far out on a single side run the chance of losing money, and losing money in betting is the quickest way to find yourself in a different industry. All these factors are why bookies normally root for the underdog–a lot of favorites winning at a sport with a short season (like the NFL) may give rise to a bookmaker to eliminate money, while a bunch of upsets (like you normally see in college football) is a guaranteed profit for your bookmaker.
The short answer here is that bookies earning money has nothing at all to do with your own gaming. It is almost unheard of for one customer to be permitted to place enough stakes to sink a single book on his own. High rollers in sport gambling get exceptional privileges concerning their maximum bet size, but these privileges often vary with all the bettor’s fortune –maximums become raised after the bettor sees big losses and diminished (sharply) as soon as the bettor starts to get lucky.
Simply speaking, a sportsbook’s profits aren’t necessarily impacted directly by the way a single wager 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 seldom is an individual bettor gambling against the bookie.
Sports Betting Odds
Remember at the start once we talked about the magic number necessary to ensure a break-even week in sports gambling? If you read enough about sports gambling, you are going to hear this amount repeated often: 52.4%. If a bettor can win 52.4% of his bets, he will break . Where does that number come from?
If betting the spread, you get odds of -110. Sometimes, sportsbooks will offer a -105 line for a marketing or to welcome new business. But for the most part, if you’re betting the spread, you’re getting -110.
We draw that 52.4% break even quantity right from the odds. -110 is equivalent to 11/10. That means if you bet 21 games, you’d have to win eleven of them and lose ten of them to split completely even. At -105, you would still need to acquire an astounding 51.2percent of the time just to break even.
If you don’t trust the simple mathematics behind this break-even principle, then look at another real life example. Let’s say that you get into sports betting after your Cowboys cream the Redskins and you go home with a great fat wallet. You then bet on the subsequent 10 Cowboys games, winning six times and losing four times.
That 60% betting record (with the likelihood of -110 that is standard for against the spread bets in soccer ) will leave you with a gain of $160. Consider 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 the small differences between a 52.4% winning rate plus a 60% winning rate–inside those 7.3 percentage points is located hundreds of dollars in profit.
Now imagine instead that you misplaced one of these six winning bets, leaving you with a 50% gambling record. You invested a total of $1,100, won $500, and dropped $550. That means overall your 50% listing drained your wallet by $50. That is where the vigorish will get you. Not even winning half the time is great enough to crack even in sports betting.
Professional Sports Bettors
Believe it or not, some people really do bet on sports for a living. Perhaps they work part time in a sportsbook or in certain other marginal job from the casino business, but there’s a group of players who wager on sports due to their life’s work. With all the math swirling around in our minds following the last piece of this guide, it is hard to imagine anyone wanting to do so for a living.
If you are aware that a 52.4% listing will mean that you break even, the easiest way to turn sports betting into a career is to bet enough to ensure a 53% winning album will bring in the kind of cash you want to make.
Another instance. After your successful Cowboys experimentation, you choose to invest $10,000 in sport betting through the initial four months of the following football season. That $10,000 is set aside to acquire or shed sportsbooks.
You plan on betting on 160 games during your investment interval. You dream of a 55% winning album as your win-loss with a 55% winning album would give you an 88-72 record. That’s an expected gain of +8.8 units. How did we get to this number? To compute your components, subtract the total of your losses (multiplied by 1.1 to incorporate the vig) from your wins and you’ll get your unit gain.
Placing $460 bets on each of those 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, could result in a $4,048 profit if you maintain that 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 bank for that sort of return on your savings accounts.
But that’s all assuming you can select the winner 55% of this time. Do your research, check into the records of professional sports gamblers. 55%, although not impossible, would put you among the elite sports bettors from the country, or even the entire world.
Professional sports bettors have to fret about variance over any other type of gambler. Working against the forces of variance means managing your bankroll over the course of this season to avoid the negative possibilities that could totally empty your wagering account. Professional sports bettors have the time and resources required to compute these variances, and there are a few pieces of software out there which can help you figure out your perfect stake in the face of negative variance. Nevertheless, the bottom line is that professional sports bettors might dream of having a 55% winning album, simply because it ensures you’re beating the house.
FURTHER INFO NOTE:
Pro bettors make their money on stakes that sportsbooks provide that give them the smallest betting advantage. The real key to becoming a profitable sports bettor is having the ability to locate benefits, opportunities where the line a book is offering is exposed.
That is why a lot of long-term sports bettors are mathematics freaks. Superior sports bettors understand statistics, especially what are known as inferential statistics, though any greater mathematics can help when it is time to put a wager.
Here is what a professional baseball bettor can perform in his mind. After looking over statistics from MLB (kept religiously by all kinds of writers, data archives, and magazines) involving the years 2000-2010, he notices a specific statistic pop out. For example: when the home team begins a left-handed pitcher daily following a loss, that team wins 59 percent of their time. Good sports bettors can do this kind of math in their mind or quite fast on paper. From this piece of advice comes a new gaming concept –look for sport situations that mirror the preceding case and wager on them. Meaning he’ll only bet games in which the home team begins a left-handed pitcher the day following a reduction. Can he simply jump in and start betting based on this back of the napkin math? No way. More statistical analysis is needed –he may find that this was a fluke for that specific decade and is not a trusted statistics, or he may discover an even more advantageous bet based upon his original concept.
Professional sports bettors also keep near-obsessive recordings of their bets. Evidently, no advantage in sports gambling lasts more than a single game. Taking proper records will also help you test 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’s a Good Record for Sports Bettors
So, at the end of the day, what would you call a »great » record for a sports bettor? Most casual gamblers searching into sports betting see a professional advertising his 1100-900 record and shake their head a little. How could this kind of abysmal record be something to be proud of? That’s a 55% winning percentage, and it indicates to those in the know this bettor is actually turning a profit putting bets on sports. A fantastic record to get a sports bettor is any record equal to or larger than 52.4 percent, since that number or anything greater means you’re not losing money. A 53% winning record, although not impressive on paper, means you’re really beating the sportsbook and putting money back in your pocket. Ask your buddies that play the slots or play online poker how frequently they wind up putting money back into their pocket.
A -110 bet, regular for spread bets in the NFL, gives the home a built-in advantage of 10%. It means that even if you do win, and you line up to collect your $100, some sucker supporting you just spent $10 to hand the casino $100.
A good record for sport bettors is any recording that guarantees that they break-even. If you bet 16 games this NFL season and you also won 9 and lost 7, then you probably made money. And taking money away from a casino is always a thing to be proud of.
