How to use the Sports Betting Hold Calculator
The sports betting hold is an inevitable component of the sportsbook industry, and our sports betting hold calculator online is the best way for bettors like you to help mitigate the impact of the system.
While it is true that the house always wins, because of the sports betting hold, our sports betting hold calculator helps give you meaningful insights on how to minimise your losses. This article will explain what the hold actually is, why it exists, and how you can best go about navigating your way through one.
What is a Sports Betting Hold Calculator - The mathematics of betting
Our sports betting hold calculator is a mathematical device used to help determine the value of a bet, before you place it. When using our sports betting hold calculator online, you will be able to determine the percentage of the betting income that a bookmaker or sportsbook is set to keep after you wager on any given market.
Our sports betting hold calculator will give you an accurate read on what percentage of all the money taken from bets will be retained by the sportsbook or bookmaker, regardless of the wagering outcomes for that market.
That sports betting hold (percentage) is designed to help ensure that the bookmaker or sportsbook operates off a profit. The absence of a sports betting hold will almost certainly guarantee that the sports betting industry collapses. However, the presence of a sports betting hold will also have practical implications for you, the punter.
Using our sports betting hold calculator online will not only confirm that a sportsbook is offering you a slightly lower return on your gambling investment, but it will also tell you just how much the sports betting odds have been lowered, compared to what the true value of that bet should be.
The use of our sports betting hold calculator online is most associated with each-way wagering options, where you are required to choose one team or player to win over another. As an extension of that you can also use our sports betting hold calculator for three-way odds, where you will also be able to place a bet on a potential drawn result.

How to use the Sports Betting Hold Calculator - Examining the odds and probabilities
Our sports betting hold calculator carries with it three key features. Like other Sports betting hold calculators, online we have one box dedicated to Side One Odds and a second box dedicated to Side Two Odds. The third box on our sports betting hold calculator is dedicated to Odds Types. Odds Types include American Odds, Decimal Odds, and Fractional Odds.
Once you have entered all of the required details in those three dedicated boxes on our sports betting hold calculator, you will click on the button to reset the odds. When the calculation has been done, a fourth dedicated box on our sports betting hold calculator will give you the Percentage of the hold.
In the build up to the UEFA European Championships Final earlier this year, the American Side One Odds (Italy) were 110. The American Side Two Odds (England) for the same fixture were -166.66. If you used our sports betting hold calculator online, you would have established that the hold was 9.19%.
The Decimal Odds for the same Side One markets would have been 2.10, while the Fractional Odds for team Italy would invariably have been 11/10. The Decimal Odds for England would have been 1.60, while the Fractional Odds would have been 3/5
All three scenarios would have given you the same hold of 9.19%. For context, if you had to bet $10 on England winning that European Championship Final, your potential payout would have been $16. If you placed the same $10 on Italy to win that European Championship Final, your potential payout would have been $21.
We have provided that context for you because using our sports betting hold calculator extends well beyond just selecting an odds format, entering your side odds, and noting the result of the hold calculation.
Once you have noted the result produced by the sports betting hold calculator, the onus will be on you to then compare those results with other markets and other bookmakers or sportsbooks.

Why you need a Sports Betting Hold Calculator - Determining the true value of your bet
You need to use our sports betting hold calculator to help you make more informed decisions when playing a sports market. Off the bat, the use of a sports betting hold calculator helps you convert sportsbook betting odds into actual probabilities. On that score, sports betting hold calculators online are particularly useful for those seeking to play each way markets. That could be for a soccer match or for a tennis match.
Sports betting hold calculators are not as useful to have when playing outright markets, where your knowledge of certain sports, like golf and motorsport, is more valuable than any price that a bookmaker is willing to offer you. An exception to this, perhaps would be a market like horse racing, where understanding the probabilities of a horse winning a race can actually be of tremendous use.
Invariably you will use betting calculators to help facilitate that process. A sports betting odds calculator is normally used to help you convert those odds into probabilities, before you embark on a campaign to remove the hold altogether.
When you remove the hold, you will get a more accurate read on what the bookmakers actually think the probabilities of success are - which is what you would call your true odds. A sportsbetting odds calculator will not only reveal that the sportsbook is often skewed, but that it is also almost always rigged against you, the punter, by either downplaying or even overstating a potential outcome.
If your use of the sports betting hold calculator tells you that a market has been significantly underpriced by a sportsbook, you can choose to either avoid placing the bet altogether or shop around for better prices with other bookmakers, which is a lot more plausible than you might think. Sportsbooks are all in competition for customers.
In some instances you might also establish that a market has actually been over priced, or that you are getting more than just tremendous value for your buck. Some sportsbook managers are either negligent about this or genuinely interested in securing your business. Either way, knowing the true odds for a game or market in this instance offers an opportunity for you, where others might not have seen one before.
Top tips for using the Sports Betting Hold calculator for the first time - Best strategies to keep winning
Shop around
Look for markets that give less of a hold to bookmakers or sportsbooks
Use our calculator
Always use a sports betting hold calculator online for proposition betting, because that is where the markets will have a higher variance
Find the best odds
While the variance with moneyline and spread betting is likely to be considerably less, it will not harm you to have the odd look using our sports betting hold calculator
Take it slow
The sports betting hold for parlays or accumulators can also be high, which is why it might be prudent of you to use our calculator for those too
Other calculators we offer - The best ways to bet
Betting odds calculator
Our betting odds calculators help you convert sports betting odds into either American Odds, Fractional Odds, or Decimal Odds. With our sport betting odds calculator, you are able to make price entries in either of those formats and still come out with clarity on what the potential payout for a given bet might be.
Parlay calculator
A parlay calculator allows you to put an entire betslip together for multiple events or markets, which then gives you an accumulated price for that market. While the accumulated prices are generally most compelling, there is a high risk for that reward, as one failed result will collapse the whole betting slip.
Odds value calculator
Our odds value calculator has been designed to help you better understand the potential value of a bet before you place it, based on potential outcomes and the probabilities of those outcomes.
Betting odds converter
Our betting odds convertor has been designed to help you better understand the nature of the odds, regardless of where in the world you are betting. If you are betting on a platform based in Europe, you are most likely to encounter decimal odds. If you are gambling in the United Kingdom, you are most likely to encounter fractional odds, and if you are gambling in the United States, you are most likely to encounter American odds.
All of those read differently and can be daunting for the uninitiated. However, our betting odds convertor will help provide meaningful clarity on all of that for you, to make sure you are not spending more than you would ordinarily need to on a bet.
Hedging calculator
Our hedging calculator has been designed to help you ensure that you do not make a loss while betting on sport. When you hedge your bets, it does not matter what the outcome of a market is. While you will not maximise your potential profits, you will at the very least minimise your losses, and more often than not you will actually break even.
Spread to moneyline converter
The spread to moneyline converter is designed to help you get a read on which bet will most likely offer you better value, the spread or the moneyline.
Conclusion - Combine your knowledge with our tools
Before placing a bet, it’s beneficial to be aware of the fact that a sportsbook is a business first. As is the nature of business, it cannot operate without some form of commission being made, leaving open the possibility for bettors to have a flutter.
Beyond that, there are those who will capitalise on your lack of experience by undercutting your bet value. Not all sportsbooks are going to be honourable or fair, so the onus will ultimately be on you to mitigate the impact of this with a sports betting hold calculator. Be sure to make use of our valuable tools to increase the potential of your betting results.

Sports Betting Hold Calculator FAQs
Which sportsbook offers the lowest hold?
There are numerous options available to bettors searching for the lowest betting hold. You can explore our platform to find the best and most established online betting sites, as they are the most likely to offer you the lowest holds. However, this does not mean that the smaller and less established online betting sites do not offer lower holds too, despite being exposed to greater financial risk. You can also learn more about them here too.
Does a low hold mean your bet will definitely win?
When you explore our guides to the best online bettings sites, you will find that some operators offer greater value on your bets than others, regardless of what the potential outcome for a market might be. You will need to use our sports betting hold calculator to find out what the hold on a betting market is, because it is not unusual for the hold to be high, even when a team or individual is expected to win a game or match.
Do sportsbooks have negative holds?
When you explore our best online betting sites, you will find sportsbooks that offer positive and negative holds. It is unlikely you will ever encounter a sportsbook that does not have a hold, which means that you need to use our sports betting hold calculator to establish what the true odds are for every match or game.
