Most people who want to place bets on sports are fans to begin with. It isn’t unheard of for a gambler to place some sports bets, especially during big games like the Super Bowl or the NCAA basketball Final Four, but for the most part, sports bettors are sports fans looking to use their knowledge of a game or of a game’s players to earn a little extra cash. Being a fan of a particular sport, a team, a college or professional squad—these are all precursors to placing sports bet. Sports betting is also a way for a fan to get in on the action of the game, with something more than self-respect at stake.

All gambling is mathematics, even games of chance. If you understand the math behind the game, you understand the game and can give yourself an advantage. For many games, like penny slots or poorly placed roulette bets, are so bad that smart bettors earn their advantage by avoiding them altogether. In sports betting, the math is more complicated. Depending on your favorite sport, you may need to think about things like bye weeks, underdogs, quarterback ratings, and injuries with the same fervor other connoisseurs reserve for fancy winces.

Some sports, like basketball and football, get the most attention and money. These sports are also hard to make money sports betting. You may find that you can make money sports betting on sports that you don’t really like. Bet on Events That Aren’t Televised, Too.

So how difficult is sports betting math? The math behind placing a winning bet is fairly complicated, but the way to stay ahead of the bookmaker is rather straightforward. If you collect on 52.4% of your bets, you’ll break even. We’ll have more details on that number later, including why it takes more than 50% wins to break even, but first some general knowledge about sports gambling and the numbers behind it.

1. Jul 15, 2020 The anti-gambling stigma that existed for decades is fading in American popular culture, opening the door for a massive, multibillion-dollar legal sports betting industry to emerge. With sports betting now legal in many states, millions of sports fans will be looking to enter the betting market for the first time.
2. For the best chance of making money on sports betting, you need to be skilled in identifying betting opportunities that represent good value. This is the real key to consistent profits and something we explain more about in the next article.

Sports Betting Basics

The easiest way to demonstrate the math behind a sports bet is to make up an example. Let’s 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 latest news about the game. While you’re sitting there, you see the wagering board, with some funny 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 favored to win and must do so by at least 5 points for a bet on the ‘Skins to pay out. The next number (-200) is the moneyline, in this case the Redskins are a 2/1 favorite. The last number (38) is the total, the over/under of the expected number of points scored in the game.

More on Placing Sports Bets

Look at that over/under number, in this case 38. If you or your buddy thinks this is going to be a particularly high or low scoring game, based on your knowledge of the team’s offenses and defenses, or information about a hurt player or bad playing conditions, you can place a wager on the total of points scored.

So how is a guy supposed to know how to literally lay down a sports bet? You need to know three things:

#1 – the type of bet you want to make
#2 – the number of the corresponding team you have chosen and
#3 – the amount you wish to wager

Knowing all that beforehand gives 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 to the meat of the sports math yet, and we’re already talking about tipping the staff behind the window? Yep. Here’s why.

If you place two $100 bets, and you win, you’ll collect $440. You should consider 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 percent mark regularly, when you win, you’re way more likely to get free drinks, which is about all you’re going to get comp-wise at the sportsbook.

So, back to the basic math of sports betting. You and your buddy, after much deliberation, decide to each place a $100 bet on your favorite team. What now?

To bet on the Redskins using the point spread, your bet is called “laying the points.” For your bet to pay off, the ‘Skins have to win by five or more to cover the spread. Remember, if the ‘Skins win by exactly four, the game is a push, and both sides recoup their bet. Another alternative is called “taking the points” with the Cowboys. That means the Cowboys have to lose by three or less for your bet to win, or if the Cowboys win outright. So you and your buddy go up to place your $100 bet, and you find out that the standard straight bet at 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 drinks to watch your bets come in.

These are deceptively simple bets. Deceptively because they make it look like the outcome of the football game is like the outcome of picking marbles out of a bag. Put one black marble and two white marbles in a bag, pull one out at random, and there’s your football game. After all, the odds are the same: 2/1 for white.

But we, as sports fans, know that the mathematics of a sporting event is much more complex. Sports bettors deeply involved in their hobby will subscribe to weather bulletins from major cities that take part in their sport, making huge wagering decisions based on a few mph of wind in one direction or another. Then there’s the unknown—does a player get hurt in the first quarter? Does weather become a factor? Is a particular player “in the zone?”

How Do Bookies Make a Profit?

Just as we finish ruminating on the concept of the difficult math at play in the background of major sporting events, we’re going to turn right back towards the simpler side of sports betting. Bookies make a profit because of vigorish. What’s vigorish?

Look at the above example again. You and your buddy each paid $10 to the bookie to place your bet. That’s what the standard 11/10 odds in sports betting are all about. You bet the Cowboys and your buddy bet the Redskins, a total of $220 bet. The sportsbook has to pay back $210 to the winner, leaving a nice $10 profit no matter what happens on the football field. That $10 built-in profit is called the vigorish, and it’s the final monkey wrench in the gears of sports betting.

Obviously, sportsbooks are going to take more than two bets on any game, but this example is for simplicity’s sake. Looking at the total number of bets on different games over the course of a week and adjusting the moneyline and other numbers is another way the bookie makes a profit. Adjusting the odds a tiny percentage point in either direction 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 if they win and keeps their money if they don’t. That’s what the job is boiled down to its essence.

When a bookie sets odds for games, he will build what bookies call an “over round” into his set of odds. Another slang term used for this formula is “the juice.” For the sake of simplicity, let’s look at a boxing match where both contenders are equally talented, of equal stature, etc. Since they both have an equal chance of winning, a casual bet may be even money. You put $20 on one guy; your friend puts $20 on the other. Whichever fighter wins awards the bettor with the total of $40.

Bookies don’t offer even money like friends in a casual betting situation. In the above example, with two evenly matched boxers, a smart bookie will offer 5/6 odds for each. That way, a $10 winning bet would only return $8.30 plus your stake. What does this do for the bookmaker? He can float an equal amount of money on both fighters, winning no matter which fighter actually wins. If they take $1,000 worth of bets on one boxer and $1,000 on the other, the bookie would take in $1,000 but only have to pay out $830, for a guaranteed $170 profit regardless of the outcome.

Bookies look at the weight of their books all the time and adjust odds and other factors to make sure their books balance. Though it isn’t possible to completely balance a book, bookies that go too far out on one side run the risk of losing money, and losing money in gambling is the fastest way to find yourself in another industry. All of these factors are why bookies generally root for the underdog—too many favorites winning in a sport with a short season (such as the NFL) can cause a bookmaker to lose money, while a bunch of upsets (like you generally see in college football) is a guaranteed profit for the bookmaker.

The short answer here is that bookies making money has nothing at all to do with your betting. It is almost unheard of for a single customer to be allowed to place enough bets to sink a single book all on his own. High rollers in sports betting get special privileges in terms of their maximum bet size, but these privileges often change with the bettor’s luck—maximums get raised after the bettor sees big losses and decreased (sharply) when the bettor starts to get lucky.

In short, a sportsbook’s profits aren’t necessarily impacted directly by the way an individual bet is called. Unlike casino games or slot machines, where it’s you against the house, sports bettors fuel the bookmaker’s business and only rarely is an individual bettor betting against the bookie.

Sports Betting Odds

Remember at the beginning when we talked about the magic number necessary to guarantee a break-even week in sports betting? If you read enough about sports betting, you’ll hear this number repeated often: 52.4%. If a bettor can win 52.4% of his bets, he’ll break even. Where does that number come from?

When betting the spread, you get odds of -110. Sometimes, sportsbooks will offer a -105 line as a promotion 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 number right out of 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 break completely even. Even at -105, you’d still have to win an astounding 51.2% of the time just to break even.

If you don’t trust the basic math behind this break-even principle, look at another real-world example. Let’s say you get really into sports betting after your Cowboys cream the Redskins and you go home with a nice fat wallet. You then bet on the next 10 Cowboys games, winning six times and losing four times.

That 60% betting record (with the odds of -110 that is traditional for against the spread bets in football) will leave you with a profit of $160. Think about it—your $600 profit from your 6 winning bets minus the $440 you lost on losing bets leaves $160. It took you $1,100 to win $160, meaning you have to bet $6.87 to win $1 on average. So you see the small differences between a 52.4% winning rate and a 60% winning rate—inside those 7.3 percentage points lies hundreds of dollars in profit.

Now imagine instead that you lost one of those six winning bets, leaving you with a 50% betting record. You spent a total of $1,100, won $500, and lost $550. That means overall your 50% record drained your wallet by $50. That’s 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 people 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 is a group of gamblers who bet on sports for their life’s work. With all the math swirling around in our heads after the last bit of the article, it’s hard to imagine anyone wanting to do this for a living.

If you know that a 52.4% record will mean you break even, the simplest way to turn sports betting into a career is to bet enough so that a 53% winning record will bring in the kind of money you want to make.

Another example. After your successful Cowboys experiment, you decide to invest $10,000 in sports gambling over the first four months of the following football season. That $10,000 is set aside to win or lose in sportsbooks.

You plan on betting on 160 games during your investment period. You dream of a 55% winning record because your win-loss with a 55% winning record would give you an 88-72 record. That’s an expected profit of +8.8 units. How did we get to that number? To calculate your units, subtract the total of your losses (multiplied by 1.1 to include the vig) from your wins and you’ll get your unit profit.

Placing $460 bets on each of these games, a number pulled from some quick and dirty math about how much you could afford to bet in a single 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 into $14,048 in just four months is an investment return of 40.48%. I dare you to ask your bank for that kind of return on your savings account.

But that’s all assuming you can pick the winner 55% of the time. Do your research, look into the records of professional sports gamblers. 55%, while not impossible, would place you among the elite sports bettors in the country, if not the world.

Professional sports bettors have to worry about variance more than any other type of gambler. Working against the forces of variance means managing your bankroll over the course of the season to avoid the negative possibilities that could totally empty your wagering account. Professional sports bettors have the time and resources necessary to calculate these variances, and there are even a few pieces of software out there that can help you figure out your ideal bet in the face of negative variance. But the bottom line is that professional sports bettors would dream of having a 55% winning record, simply because it guarantees you’re beating the house.

Pro bettors make their money on bets that sportsbooks offer that give them even the slightest betting advantage. The key to becoming a profitable sports bettor is being able to find advantages, opportunities where the line a book is offering is vulnerable.

This is why many long-term sports bettors are math freaks. Good sports bettors understand statistics, particularly what are called inferential statistics, though any higher math will help when it comes time to place a bet.

Here is what a professional baseball bettor might do in his head. After looking over statistics from MLB (kept religiously by all sorts of bloggers, data archives, and magazines) between the years 2000-2010, he notices a particular statistic pop out. For example: when the home team starts a left-handed pitcher the day after a loss, that team wins 59% of the time. Good sports bettors can do this sort of math in their head or very quickly on paper. From that bit of information comes a new betting theory—look for game situations that mirror the above example and bet on them. That means he’ll only bet games where the home team starts a left-handed pitcher the day after a loss. Does he just jump in and start betting based on this back of the napkin math? No way. More statistical analysis is required—he may find that this was a fluke for that particular decade and isn’t a trustworthy statistics, or he may find an even more advantageous bet based on his original theory.

Pro sports bettors also keep near-obsessive records of their bets. Obviously, no edge in sports betting lasts longer than a single game. Taking proper records will also help you test theories, like the above one about left-handed pitchers and losses. Without taking good records, no sports bettor’s bankroll will last very long.

What Is a Good Record for Sports Bettors

So, at the end of the day, what could you call a “good” record for a sports bettor? Most casual gamblers looking into sports betting see a pro advertising his 1100-900 record and shake their head a little. How could such an abysmal record be something to be proud of? That’s a 55% winning percentage, and it indicates to those in the know that this bettor is actually turning a profit placing bets on sports.

A good record for a sports bettor is any record equal to or larger than 52.4%, because that number or anything higher means you’re not losing money. A 53% winning record, while not impressive on paper, means you’re actually beating the sportsbook and putting money back in your pocket. Ask your friends that play the slots or play online poker how often they end up putting money back in their pocket.

A -110 wager, standard for spread bets in the NFL, gives the house a built-in advantage of 10%. It means that even if you do win, and you line up to collect your $100, some sucker behind you just spent $10 to hand the casino $100.

A good record for sports bettors is any record that ensures they at least break-even. If you bet 16 games this NFL season and you won 9 and lost 7, you probably made money. And taking money away from a casino is always something to be proud of.

Sports Betting Break Even Video:

In the video above I go over the break even % for sports betting, and we take a look at the difference between hitting 52% and 53%. I also quickly show the amounts of profits you can expect if you can hit 55% consistently.

So, what exactly is a professional gambler?

A professional gambler is a person who lives from gambling and spends most of his time at the casinos. Professional gamblers are actually earning their paychecks by making the right bets when they play at the live casino tables.

In this article, I will go over some general misconceptions about casino gaming as well as go over a few real-world examples, gathered from several friends of mine who are professional Advantage Players. We won’t give out real names or when these “adventures” occurred, but rest assured this is about as truthful as an accounting of what real-world play is like.

The gambler lifestyle has been portrayed by Hollywood, and more so, by commercials for casinos, to be a glamorous one. Men are always dressed sharply and women are in their best gowns and, both seem to be having a wonderful time. They are winning money, eating at 5-star restaurants and drinking the best champagne.

This is all done to entice the average person to come to the casinos and gamble, but more importantly to lose the maximum amount of money they can. The reality of the casino gaming world is very different.

What Makes a Pro

The term “professional gambler” is sometimes used interchangeably for both people who earn part-time and full-time income through gambling.

But I keep a much tighter definition of a professional gambler.

Real pros not only make a profit through gambling, but enough to pay all of their living expenses. This includes housing, utilities, car payment, insurance, food, clothing and anything else deemed necessary.

A semi-pro is somebody who makes enough to supplement their income but doesn’t earn a full-time living through gambling.

But, when you are on the positive side of the spectrum it’s like taking candy from a jar labeled “free candy”. The hard truth is that the mentality of a professional casino player is equal to a manic depressive.

The gambling world doesn’t offer an abundance of opportunities to make a living, but there are a few different games where you can earn some nice profits. If you play smart and stick to the plan.

Game On

Let’s take a brief look at the most common games that you can make long term profits with and I’ll then go into each with more detail:

• Blackjack
• Daily fantasy sports (DFS)
• Poker
• Sports betting

Blackjack sees you try to win money directly from the house.

Casinos do everything in their power to hinder successful card counters. This includes using continuously shuffling machines, multi-deck shoes, and vigilant security measures.

Anybody who’s caught counting cards is often kicked out of the casino and banned. This is why it’s so important for card counters to blend in with normal players.

DFS and poker both see you compete against your fellow man. The house merely takes a small cut of tournament fees or cash game pots for poker.

Sportsbooks create lines in an effort to get equal betting action on both sides. The sportsbooks make their money by taking 10% juice from the losing group.

Every form of advantage betting has its pros and cons, but the key is that each of these activities offers the chance to make a healthy income.

How To Make Money Gambling On Sports Betting

Counting on It

People have been making a living through card counting since the early 1960s, and despite all the obstacles that casinos have put in players’ way, it remains possible to earn a living with card counting today.

You need a sizable bankroll in order to properly spread your bets and survive variance. The recommended minimum you should aim for is $20,000, but it’s better to have closer to $40,000.

How much you make depends upon several factors, including the following:

• Skill level – Successful counters have between a 0.5% and 1.5% edge on casinos.
• Hands per hour – 50 to 200 depending upon dealer speed & table size.
• Bet spreading – Difference between your lowest and highest bet.
• Deck penetration – The further into the shoe you get, the more confidence you can bet with.
• Counting system – Some systems are more accurate than others.
• Game rules – You want the best rules possible in order to lower the standard house edge.
• Tips – $5 per hour for the dealer is standard.

The final step is to figure out how many hours you’ll play and convert this into an annual salary.

The key is keeping an accurate count amidst casino distractions and blending in with normal players.

Fantasy

DFS is the newest game that offers skilled gamblers an opportunity to make money.

Daily fantasy sees you pay an entry fee to enter contests and compete against other players. The goal is to create lineups that score the most points and rank the highest in tournaments.

The truth, though, is that only a small percentage of those who play actually win. A study from 2015 showed that 1.3% of daily fantasy baseball players collect 91% of the winnings.

Saahil Sud, profiled in a WBUR piece, said he made over $3 million in profits in a single year. Former poker-pro Aaron Jones switched over to DFS and won a DraftKings contest worth $5 million in early 2016.

Of course, the average professional DFS player doesn’t earn quite this much. To determine a standard DFS salary, let’s consider the following factors:

• Entries per day— Most DFS pros enter several hundred contests every day.
• Stakes – Typical entry fees range anywhere from $1 up to $1,000.
• Fees— DFS sites tack on a 10% fee to each buy-in, which is where their profits come from.
• Skill level— Some pros have a bigger edge than others.

Of course, DFS is filled with variables, which is why it’s key to have a large enough bankroll to survive the ups and downs.

Poker

Poker has long been one of the most viable options for becoming a professional gambler. The reason why is because you’re competing against other opponents instead of the house.

It’s tougher to make a living in poker these days because the strategy is more prevalent. Real money online poker gives players a chance to rapidly accelerate their learning curve by seeing more hands per hour.

You can still become a profitable player with enough hard work and experience though. In fact, some pros still make six or seven-figure annual incomes with the game.

However, the vast majority of pros these days earn between $40,000 and $100,000 per year.

Poker is unique in that there are essentially two types of professionals: tournament and cash game pros.

Let’s look at the different considerations for cash vs. tournament play:

How To Make Money On Sports Spread Betting

Cash Games

• Profit measured in big blinds (BB) made per hour.
• House takes 5% rake from cash game pots for running games.
• More control over annual salary than tournaments.

Tournaments

• Profit measured by rate of return (ROI) on buy-ins.
• House adds 10% fee to buy ins (e.g. $10 + $1 fee).
• Only the top 10-15% of the field makes money.
• Tournaments have more variance than cash games.

A cash player must figure out what stakes they must play to make a comfortable living based on BB earned per hour.

A tournament pro must decide what buy-in level they must choose to make a high enough ROI to live comfortably.

One more consideration here is whether you’ll dedicate the bulk of your time towards live or online poker.

How To Make Money Gambling On Sports Network

Online cash games and tourneys offer more volume because you can play multiple tables. Plus hands and tournaments go much faster, giving you an opportunity to boost your hourly wages.

Nevertheless, many players find that their win rate is higher in live games. The most lucrative tournaments are found in land-based casinos, too, such as the World Series of Poker events.

Sports Betting

The good thing about sports betting is that you don’t need to have a massive win rate just to book profits.

Sportsbooks only take 10% juice from the losing side. This differs from DFS and poker tournaments where you must pay an extra 10% fee regardless of whether you’re a winner or loser.

The juice can be lowered or adjusted based on where the sportsbook is trying to push action, but 10% is generally the amount you’ll see taken from the losing side.

Pro sports bettors must be very keen at handling their bankroll since they’re dealing with such small profit margins. They also need to make larger wagers than “Gary the CPA from Ohio” to increase potential profits.

Some sports bettors have made millions of dollars with this model. But the average bettors are looking at more modest salaries ranging from $50,000 to $150,000 annually.

Conclusion

Being a pro gambler has some obvious benefits, including flexible hours, being your own boss, and the ability to increase your income.

Some gamblers, such as Saahil Sud and Bob Voulgaris, have even gotten rich with their skills. Of course, you may be perfectly happy making mid-5-figures, as long as you get to enjoy the aforementioned benefits, but there are also some downsides to be aware of. These include risk, highs and lows, no sick days, and the potential to lose everything.

The potential rewards can be great in the case of card counting, DFS, poker, and sports betting, but you also have to be disciplined and good at handling risk.
