Teaser Bet Calculator
A teaser is a sports bet that is similar to placing a parlay bet.Both types of wagers are made by selecting two or more events to occur. Like a traditional parlay, each event selected for a teaser must win in order for the player to win to win the bet. You could make a two-team, six-point teaser bet with Buffalo and New England. In this example are betting that Buffalo will win by more than four points (10 - 6 = 4) and New England will win by more than one point ( 7 - 6 = 1). In the case of a tie or push in a two-team teaser, your wager is refunded. Enter the amount of money you wish to bet. Our calculator will take care of the rest. You’ll see how much money you’ll win, and the total payout you’d receive. We set the bet amount to $100, but you can enter any amount you want as long as your bankroll can handle it.
Moneyline bets present the most straightforward way to wager on a sports contest. A moneyline wager simply asks the bettor to choose which team will win a game, with no point spread involved.
The payout odds on the favorite and underdog can differ significantly on a moneyline bet. Using a moneyline calculator breaks down the math on the odds, which allows bettors to assess the true value on each side.
The following page includes the GamingToday.com MoneyLine Calculator, as well as several valuable tables and graphs designed to help bettors gain an edge with moneyline bets.

What Is A Moneyline Bet?
Legal US sportsbooks generally present several different ways to wager on sports. Moneyline bets represent just one of several different wagering options, which include point spread, totals, parlays, and in-game betting.
Moneyline Bets
A moneyline wager allows the bettor to put a bet on which team or athlete will win a contest, straight up. The moneyline underdog will always pay out at better odds than the favorite.
Skilled bettors look for value on moneyline bets by evaluating teams that have a better chance of winning than the implied probability of the odds might dictate.
Moneyline favorites are listed with “-” odds, and the underdog is listed at “+” odds.
For example, here’s a look at a line offered by PointsBet on Game 1 of the 2020 World Series:
| Point Spread | Total | Moneyline | |
|---|---|---|---|
| Tampa Bay Rays | +1.5 (-150) | Over 7.5 (+100) | +140 |
| LA Dodgers | -1.5 (+130) | Under 7.5 (-121) | -165 |
American Odds
PointsBet sets the Los Angeles Dodgers as the favorite in the game, with -165 moneyline odds. To calculate “-” odds, divide 100 by the odds, then multiply that quotient by the amount you bet.
For example, suppose you want to calculate how much profit a $50 bet on the Dodgers would yield. First divide 100 by 165 (without the “-”), which yields 60.6. Then multiply that number by your $50 bet to arrive at the profit (60.6*$50=$30.30).
A $50 bet on the Dodgers at -165 odds would yield $30.30 in profit. The $50 wager would return $80.30 to the bettor ($30.30 profit plus the original $50 bet).
To calculate “+” odds, divide the odds by 100 and multiply that product by the amount of the wager.
A $50 bet on the Tampa Bay Rays, for instance, would calculate as 140/100 (which yields 1.4), multiplied by $50 (1.4*$50=$70). A winning $50 moneyline bet on the Rays returns $120 total to the bettor ($70 profit plus the original $50 bet.)
Decimal Odds
Decimal odds can be used to make a simple calculation of odds multiplied by wager amount to arrive at the total amount returned to the bettor.
The -165 odds on Los Angeles, for example, convert to 1.6061 decimal odds using the Gaming Today moneyline calculator. Multiplying that by a $50 bet yields $80.30, and subtracting the original bet amount yields the profit earned ($80.30-$50=$30.30).
What Is A Moneyline Calculator?
The Gaming Today Moneyline Calculator allows for quick calculations for any wager amount and payout odds. Using American, decimal, fractional, Hong Kong, Indonesian, or Malay Odds, you can input the odds and the amount of a wager and see the payout that would come if the bet is a win.
While it’s valuable to understand and be able to calculate favorite and underdog Moneyline odds for all of the different odds notations, the moneyline calculator can save a significant amount of time and energy.
One of the most important features of the Gaming Today Moneyline Calculator is the Implied Probability feature.
For any favorite or underdog input, the calculator produces the implied probability of that team winning. Astute bettors can use the calculator to find teams that have a higher actual win probability than the implied probability dictated by the odds.
The “To Win” window displays the amount of profit yielded by any combination of odds and wager amount. To calculate the return to the bettor, add the “To Win” number to the original amount of the wager.
How To Use The Moneyline Calculator To Place A Sports Bet
Suppose you wanted to put the Gaming Today Moneyline Calculator to work to decide how you wanted to bet on Game 1 of the 2020 World Series. Here’s another look at the lines offered on that game by PointsBet:
| Point Spread | Total | Moneyline | |
|---|---|---|---|
| Tampa Bay Rays | +1.5 (-150) | Over 7.5 (+100) | +140 |
| LA Dodgers | -1.5 (+130) | Under 7.5 (-121) | -165 |
To calculate a $50 moneyline wager on the Tampa Bay Rays, input $50 in the “Bet Amount” window and put “+140” in the “American Odds” window. Hit enter or click on the “Convert Odds” button and see how the moneyline calculator converts that information into several different useful categories.
The calculator converts the “+140” odds into all of the different notations you might see used by a sportsbook.
The +140 American odds convert to 2.40 decimal odds, 7/5 fractional odds, 1.40 for Indonesian/Hong Kong odds, and -0.7143 Malay Odds. A tool like our moneyline calculator can be a crucial component of a betting strategy when evaluating odds at sportsbooks that use different notations.
The “Implied Probability” output tells you that at +140 odds, the Rays have a 41.67% implied probability of winning. A skilled bettor will take that bet if they think Tampa Bay’s actual chance of winning the game is higher than that.
The “To Win” output yields the profit produced if the Rays win. A $50 winning bet on the Rays yields $70 in profit and a $120 total return to the bettor ($70 profit plus the $50 original bet).

Calculating Positive And Negative Moneyline Odds
The math used in calculating the payout on a moneyline is pretty simple. It is one of the most important first steps to understanding sports betting and is crucial to success. Below is a graph of profit won on $100 bets for negative odds. Note that it is a curve that approaches, but will never get to $0. Even -1,000,000 odds still yields some profit from a win:
And here is a graph of profit for positive numbers. The really important difference is that the line is linear. as the odds increase, so does the profit. That goes on forever.
Looking at the odds offered by the sportsbook, note whether they are negative odds (for example -110) or positive odds (for example +120). The calculation changes based on if it is a positive or negative odd. Below we work through an example of a bet of $100 at -110 moneyline odds. It is important to notice that multiplying by -1 is required to give us the positive payout:
PAYOUT = BET AMOUNT / (-1 *MONEYLINE ODDS / 100)
So that looks like:
$90.91 = $100 / (-1 * -110/100)
That also means that you will be returned that amount AND your original bet, meaning you now have $190.91. Let’s work another negative example of a $100 bet at -150:
$100 / (-1 * -150 / 100) = $66.67
Now let’s work through a positive money example. Let’s say you bet $100 at +120
PAYOUT = BET AMOUNT * ODDS / 100
That looks like:
$120 = $100 * 120 / 100
In that case, you are returned your original bet plus profit, so you now have $220.
What Is Line Movement?
Sportsbooks make money by setting lines that bring in an appropriate amount of wagers on both sides of a bet. The house offers odds that factor in a cut of overall wagers, known as vig, that goes to the sportsbook.
In the World Series Game 1 example from above, if 90% of bets come in on the Dodgers, the sportsbook stands to lose big money if Los Angeles wins. A Tampa Bay win in that situation is even more disastrous for the sportsbook.
If the bets coming in on a game are too one-sided, the line on the game will start to move to try to prompt more bets for the other side. It’s important to remember that sports betting isn’t a zero-sum game, and you’ll be losing in the long run even if you win 50% of the time.
Legal Online Sports Betting In The US
A federal mandate known as the Professional and Amateur Sports Protection Act (PASPA) was overturned in May 2018, giving US states the legal clearance to offer state-regulated sports betting. Several states now offer both retail and online sports betting, including New Jersey, Pennsylvania, Nevada, Illinois, Indiana, Colorado, and several others.
The top online sport betting brands in the US include the following:

Yes. More than a dozen states either currently offer online sports betting or have a launch of mobile sports betting products pending.
New Jersey, Nevada, and Pennsylvania represent the three biggest online sports betting markets in the US. Other states with legal online sports wagering include Colorado, Illinois, Indiana, Iowa, West Virginia, and a few others.
The Gaming Today Moneyline Calculator can be used as a valuable resource on any moneyline bet. It’s especially useful for evaluating the implied probability of winning and payout odds.
The moneyline bet calculator’s ability to display odds across multiple notation formats (American, Decimal, Fractional, Indonesian/Hong Kong, and Malay odds) allows bettors to compare lines across sportsbooks that use different notations.
Even if you’re a veteran sports bettor, running every bet you’re considering through the calculator provides significant benefit.
Yes. Nothing in the terms and conditions of any US legal online sportsbooks prohibits the use of a moneyline calculator.
The calculator provides computations that any person could produce with pen and paper but in a much faster and more efficient manner.
For “+” American odds, divide the odds by 100 and convert that quotient into a fraction. To convert +160 into fractional odds, for example, divide 160 by 100 (160/100) and reduce that fraction to the lowest whole number denominator. American odds of +160 would convert to 8/5 fractional odds.
For “-” American odds, divide 100 by the odds and convert to the simplest form fraction. For -160 odds, for example, the calculation looks like 100/160, which reduces to 5/8 fractional odds.
To convert “+” American odds to implied winning probability, the formula looks like this:
100 / (“+” American odds + 100)*100 = implied probability
For example, +160 odds would be calculated as 100/(160+100)*100. This converts to 100/260*100, which ends up yielding a 38.46% implied probability.
To convert “-” odds, the formula looks like this:
“-” odds / (“-” odds + 100)*100 = implied probability
For instance, -160 odds would translate to 160/(160+100)*100, converting to 160/260*100, which yields a product of 61.54. The implied probability of -160 odds is a 61.54% chance of winning.
Several online sportsbooks offer comprehensive coverage of sports and ways to bet. Some of the best choices for online sports betting in the US include DraftKings Sportsbook, FanDuel Sportsbook, PointsBet, FOX Bet, and BetMGM.
Warning
This page is rather dated and limited in scope. I recommend you visit my page on Teaser Bets in the NFL instead.
Introduction
A teaser is similar to a parlay bet in that the player ties multiple wagers together and the cumulative bet wins only if the wagers all win together. Where the teaser differs from the parlay is that the point spread is moved a specified number of points (usually 6 to 7 points) in the player's favor on all picks. The player pays for those points in the form of much lower wins than a parlay bet. For example, a 2-team parlay usually pays 13 to 5, but a 2-team 6-point teaser usually pays 10 to 11. On teasers, each pick is called a 'team.' I always thought this was confusing, because the player can choose over and under bets too. Personally, I prefer to use the term 'pick,' but on this page I use the terms 'pick' and 'team' interchangeably.
As with a parlay, every pick must win in order for the bet to win. In the event one or more events end in a push, then those picks are ignored. For example, if a 4-team teaser results in 3 wins and 1 push, then it would pay as a winning 3-team teaser. In the rare event a teaser is reduced to just one pick, then it usually pushes, because there is no such thing as a one-team teaser. An exception to this is The Greek Internet sports book, which treats any teasers with a losing pick as a loss. Otherwise, don't throw away a teaser bet if the first game loses, because it will still push if every other pick results in a push.
Let's take a look at an example. The image to the side is of a teaser bet I made in 2004. The following would have been the normal point spreads that week:
- Bengals +2.5
- Buccs -8
- Chiefs +2.5
- Colts -8.5
However, because I did a 6-point teaser, all the point spreads moved six points in my favor, to the following:
- Bengals +8.5
- Buccs -2
- Chiefs +8.5
- Colts -2.5

If I covered all four of these spreads, then I would have been paid 3 to 1. Since I made that bet, teaser odds have gone down. The Suncoast now pays only 5 to 2 for a 4-team 6-point teaser, for example. The outcome of the teaser above is I won two and lost two, so the bet lost.
Probability of a Single Pick Winning
A good place to start an analysis of teasers is to find the probability of any given pick winning. I looked at every regular season NFL game between the 2000 and 2011 seasons. Then I cut the results by the number of points given, and whether the pick was on a home team, away team, under, or over. The 'all sides' column is the average of both sides of all games against the spread.
The most common teasers give the player 6, 6.5, or 7 extra points. However, I've seen teaser cards with an unusual number of points given. To be complete, I analyzed everything from a 0 to 14-point teaser, although many of these you will never see.

What does the table above tell us? For the common teasers of 6 to 7 points, away teams are slightly better than home. It also shows that overs are slightly better than unders. The most important thing to notice is that teasing sides is significantly better than teasing totals.
The sports book review at my Wizard of Vegas site indicates what all the major sports book families pay on teasers. The next table shows the expected return on 6, 6.5, and 7-point teasers under all known pay tables, for all side and all total teasers.

As you can see, teasing random picks results in a very high house edge most of the time. As a rule of thumb, teasers are a sucker bet. However, with some skill you can get the odds in your favor.
Wong Teasers
The two most common margins of victory in the NFL, by far, are 3 and 7 points. My sports betting appendix 2 shows the probability of each margin of victory. Briefly, 15.9% of NFL games are decided by exactly 3 points and 9.6% are decided by 7.
In his outstanding book Sharp Sports Betting, Stanford Wong noted that by crossing the 3- and 7-point margins of victory with a 6-point teaser, the player could have an advantage. However, his book is now somewhat dated, and results since its publication have not been good for what are known as 'Wong teasers.' Let's take a fresh look at them. Again, all the results in this page are based on regular season games from week 1 2000 to week 4 2010.
Wong Teasers
| Bet | Wins | Games | Ratio Wins | Standard Deviation |
|---|---|---|---|---|
| Home underdogs | 90 | 126 | 71.43% | 3.98% |
| Home favorites | 109 | 144 | 75.69% | 3.72% |
| Away underdogs | 124 | 170 | 72.94% | 3.42% |
| Away favorites | 31 | 48 | 64.58% | 6.44% |
| All home | 199 | 270 | 73.70% | 2.72% |
| All away | 155 | 218 | 71.10% | 3.02% |
| All underdogs | 214 | 296 | 72.30% | 2.59% |
| All favorites | 140 | 192 | 72.92% | 3.22% |
| All | 354 | 488 | 72.54% | 2.02% |
The table above shows the probability of a Wong teaser winning ranges from 64.58% to 75.69%. I tend to think this is just random variation and that the overall win rate of 72.54% is the significant statistic. The next table shows the expected return of Wong teasers according to the number of teams and the odds a winning bet pays.
Wong Teaser Expected Return

| 5 | 3 to 1 | -19.65% |
| 6 | 7 to 1 | 16.57% |
| 6 | 13 to 2 | 9.29% |
| 6 | 6 to 1 | 2.00% |
| 6 | 9 to 2 | -19.86% |
| 7 | 11 to 1 | 26.84% |
| 7 | 10 to 1 | 16.27% |
| 7 | 9 to 1 | 5.70% |
| 7 | 8 to 1 | -4.87% |
| 7 | 7 to 1 | -15.44% |
| 8 | 15 to 1 | 22.68% |
| 8 | 12 to 1 | -0.32% |
| 8 | 10 to 1 | -15.65% |
The table above shows the classic 2-team teaser that pays 10 to 11 is barely good any longer, with a player advantage of about half a percent. To have an advantage worth bothering with, you need at least three teams and the premium odds. Here is Nevada, when last I checked in 2010, your best chance at a good Wong Teaser is the 4-team teaser that pays 3 to 1 at Leroy's sports books. You can use my Las Vegas sports book groups page to find which cases have a Leroy's outlet.
Teaser Cards
Teaser Bet Odds
I have not checked every teaser card out there, but those I have checked I found to be a lousy bet. Consider the Boyd Gaming 'Super Teaser' card, for example. For the Monday Night Football game of October 18, 2010, they had the Titans +5 and the Jaguars +12. Ties always win, and every point spread is an even number, so that is the same as Titans +5.5 and Jaguars +12.5. That is mathematically equivalent to a 9-point teaser. The following table shows the pay table, probability of winning, and expected return for a random picker.
Boyd Super Teaser
| Picks | Pays (for one) | Probability Win | Expected Return |
|---|---|---|---|
| 4 | 2 | 32.99% | -34.01% |
| 5 | 2.5 | 25.00% | -37.49% |
| 6 | 3.5 | 18.95% | -33.67% |
| 7 | 4.5 | 14.36% | -35.37% |
| 8 | 6 | 10.89% | -34.69% |
| 9 | 7.5 | 8.25% | -38.13% |
| 10 | 9.5 | 6.25% | -40.60% |
| 11 | 12 | 4.74% | -43.14% |
| 12 | 15 | 3.59% | -46.13% |
| 13 | 20 | 2.72% | -45.56% |
| 14 | 25 | 2.06% | -48.43% |
| 15 | 30 | 1.56% | -53.10% |
The upshot of it is that this Super Teaser card is a lousy bet. You might say, what if the player only crossed through key totals. I found that didn't help much. To make things worse, they give the player only 8.5 points on totals, when they should offer more points than for sides, to be fair.
Pre-Season Teasers
Most sports books don't allow teasers on pre-season games. However, if you find one that does, I think Wong teasers would be a strong bet. This is because you find a lot of games with a 1.5 to 2.5 spread, and the games tend to be low scoring, and decided by small margins of victory. I don't have data on pre-season games, so this is anecdotal advice only.- Betting MLB In-depth look at betting professional baseball.
