Basics of Sports Betting Math
Grasping the numerical principles behind sports betting is crucial for making informed bets. For instance, here’s a familiar scenario you’ll find at any betting establishment. moneyline bet Illustration of a typical betting line at BetOnline sportsbook. This includes moneyline, total, and run line odds for a matchup between the Miami Marlins and the St. Louis Cardinals during the MLB season.

The odds indicate that if you place a $100 wager on the Marlins and they win, you’ll earn a $134 profit. In contrast, a $146 bet on the Cardinals would lead to a $100 profit, provided they win. BetOnline offers this moneyline:
- Marlins: +134
- Cardinals: -146
This suggests that the Cardinals are favored, as the potential profit for every $100 wagered is less compared to that of the Marlins, according to the bookmaker’s assessment.
The simplest way to comprehend sports betting math is by examining the figures involved. A lower number reflects higher likelihoods of winning, according to the bookie's perspective, albeit with a corresponding decrease in potential profit. Conversely, higher numbers indicate greater profit prospects but also carry increased risk.
You can certainly make significant earnings from sports betting, but it requires meticulous attention and effort. There’s a prevalent misconception that winning or losing bets is purely based on luck. By making wiser choices and having a solid grasp of sports betting math, you can lessen your dependency on luck.
How To Make Money Sports Betting
To generate profits through sports betting, you must secure more wins than losses overall. However, it’s not merely a matter of 50/50. Bookmakers earn their income by taking a minor percentage from every bet placed, known as vigorish or juice. As a result, successful bettors must aim to win approximately 53% of their wagers to break even.
All winning sports betting strategies start with building a solid knowledge foundation that allows you to implement your approach effectively. With a clear understanding of the math involved in sports betting, you can make automated intelligent choices.
How To Use Sports Betting Math
Before you start placing any bets, here are essential foundational concepts we suggest you grasp:
Recognizing how betting odds function is vital, as well as picturing the winning probabilities associated with those numbers. In sports betting, higher odds imply a lower likelihood of winning, thus posing a greater risk. The trade-off is that the potential returns on such bets are more substantial.
1. Understand Betting Odds and Lines
Implied probability does not equate to true mathematical probability but is simply another method of reflecting payout odds. This principle is central to strategic sports betting - identifying wagers where you believe the true odds diverge from those set by the bookmaker.
What is implied probability?
Differentiating between true odds and implied odds may be complex.
Click here for more insights into betting odds. Any odds registered at +100 or higher reflect an implied probability below 50%, while being potentially more lucrative. Conversely, odds below -100 indicate an implied probability above 50%, but offer diminished profitability.

- Golden State @ -110
- Bulls +8.5 points @ -110
2. When crafting your profit margin and devising your betting strategy, it is crucial to incorporate the bookmaker's share into your calculations.
Your profit margin represents the amount you aim to retain after the sportsbook claims its portion. If you win exactly 50% of the time at even odds, you will incur losses owing to vigorish.
This implies that bettors must target higher odds to offset the bookmaker's cut. While this may seem marginal, it explains why most gamblers seek at least a 5% profit margin, requiring them to win approximately 55% of the time.
Utilize your anticipated profit margin to assess the expected value of your bets. This reflects your average profit in the long term.
3. Calculate Expected Value
To win 55% of the time and achieve a slim profit while offsetting the vigorish owed to your sportsbook, pay attention to negative odds:

- If you participate in 10 bets of $100 each and emerge victorious in all, your total profit would amount to $820. However, the likelihood of this scenario unfolding is slim, and a more realistic goal would be to win a minimum of 55% of your bets.
- Achieving a 55% win rate leads to a profit of $451 from successful bets – $450 lost from unsuccessful attempts would leave you with $1 overall profit. Winning another bet would increase your total profit by $82.
- Alternatively, you may opt for betting on positive odds, which offers a potentially better payout but entails greater risk:
Odds of +122 reflect an implied probability of 45%, providing a $122 profit for every $100 wagered.
- If you place 10 bets of $100 each and win all of them, your earnings would total $1,220. While such a result is unlikely, your aim should be to secure a win rate of at least 45% to realize a profit.
- Winning 45% of the time translates into a profit of $549 from successful wagers – tallying to $550 will yield -$1 in total (a victory on one more bet increases your profit to $121).

- Grasping the arithmetic associated with sports betting is crucial for making well-informed betting decisions. Here’s a typical example that you will likely encounter at any betting site.
Example: Consider this standard betting line featured on the BetOnline sportsbook, which outlines moneyline, totals, and run line odds for a matchup between the Miami Marlins and St. Louis Cardinals in Major League Baseball.
Here’s the calculation:
- f* = (2 x 40% – 60%) / 2 = 0.10
The Marlins are scheduled to face off against the Cardinals in a regular season MLB game.
The odds indicate that for every $100 wagered on the Marlins, you stand to profit $134 if they win. In contrast, you’ll need to bet $146 on the Cardinals to profit $100, assuming they are victorious.
This data suggests that the Cardinals are the favored team according to the bookmaker's evaluations, as the profit potential for betting on them is lower per $100 wagered compared to the Marlins.
A simple way to understand sports betting mathematics is to analyze the figures presented. Generally, lower odds imply a higher likelihood of winning in the bookmaker's perspective, yet they also translate to lower profit potential. Conversely, higher odds may promise greater returns but come with increased risks.
Statistical Modeling:
While it is indeed possible to earn significant amounts from sports betting, it necessitates meticulous attention and effort. A common misconception is that chance determines success in sports betting. However, making informed decisions through a solid understanding of betting math will reduce your dependency on luck.
Example: To ensure profitability in sports betting, you must win more often than you lose overall. However, this isn't simply a 50/50 situation. Bookmakers earn money by taking a small cut of every wager, often referred to as vigorish or juice. Consequently, bettors need to achieve a win rate of approximately 53% to break even.
Effective sports betting strategies commence with building a foundational knowledge, allowing you to successfully implement your strategy. By comprehending the mathematics involved in sports betting, you can streamline your decision-making processes.
Here are the essential principles we suggest you establish before entering the betting realm:
Grasping how betting odds function and visualizing the probability of winning through these numbers is vital. In sports betting, higher odds often represent a lower chance of winning, making them inherently riskier. The advantage, however, lies in the possibility of achieving higher payouts.
Implied probability should not be confused with mathematical probability, as it serves as an alternative representation of payout odds. Recognizing this distinction is key to strategic sports betting – your goal is to find bets where you believe the true odds differ from those proposed by the bookmaker.
Determining true odds in comparison to implied odds can be a complex task.

Discipline and Patience:
The challenge is compounded by the fact that betting platforms also take a cut from every stake before a bet is settled. This commonly results in lines like:
In this scenario, both teams have odds of -110 for victory, where the Bulls have a +8.5 point advantage to balance the odds. Even if both outcomes seem equally likely with a 50% chance of winning, you will earn only $91 for every $100 staked due to the vigorish, rather than the full $100. The implied probability for these lines comes to 110/210 = 52.38%, resulting in a total of 104.76%. Any value exceeding 100% represents the bookmaker's commission.
TIP: Define Your Profit Margin and Account for Vigorish
Record Keeping:
When devising your profit margin and formulating your betting strategy, it's crucial to account for the 'house take.'
Your profit margin indicates what you expect to keep after the sportsbook takes its share. For instance, if you win bets half the time, you would end up at a loss due to the vigorish.

Knowing When To Fold:
You can leverage your anticipated profit margin when determining the expected value of your bets, representing your average long-term profit.
To achieve a winning rate of 55% and ensure a slight profit while covering the vigorish owed to the sportsbook, it's wise to concentrate on negative odds:
