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. The moneyline underdog will always pay out at better odds than the favorite. But underdogs are more likely to lose, so there’s an important tradeoff. 

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 suggests. Sharp bettors are sharp because they can come with up their own estimations of whether a team will win. So, bettors who want to become sharps must hone this crucial skill. 

Moneyline favorites are listed with “-” odds, and the underdog is listed at “+” odds. 

For example, here’s a look at a line offered by Caesars Sportsbook on the 2022 Bills/Chiefs game:

 Point SpreadTotalMoneyline
Buffalo Bills+2.0 (-110)Over 55.0 (-110)+115
Kansas City Chiefs-2.0 (-110)Under 55.0 (-110)-135

American Odds

Caesars Sportsbook sets the Kansas City Chiefs as the favorite in the game, with odds of -135 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 135 (without the “-”), which yields 0.74. Then multiply that number by your $50 bet to arrive at the profit (0.74*$50=$37).

A $50 bet on the Chiefs at -135 odds would yield $37 in profit. Then, the $50 wager would return to the bettor. So, the bettor would earn $87 total from a win on that bet.

To calculate “+” odds, divide the odds by 100 and multiply that product by the amount of the wager. 

To calculate the payout of a $50 bet on the Buffalo Bills, divide 115/100 and multiply by $50 (1.15*$50=$57.50). A winning $50 moneyline bet on the Bills returns $107.50 total to the bettor. ($57.50 in profit plus the original $50 stake.)

Decimal Odds

Decimal odds can be used to make the calculations above simpler.

For example, bettors can use the Gaming Today moneyline calculator to convert Kansas City’s -135 odds to 1.74 decimal odds. Multiplying 1.74 by a $50 bet yields $87, and subtracting the stake yields potential profit ($87-$50=$37).

What Is A Moneyline Betting Calculator?

The Gaming Today Moneyline Betting 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 Betting 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 a game. Here’s another look at the lines offered on that game by Caesars Sportsbook:

 Point SpreadTotalMoneyline
Buffalo Bills+2.0 (-110)Over 55.0 (-110)+115
Kansas City Chiefs-2.0 (-110)Under 55.0 (-110)-135

To calculate a $50 moneyline wager on the Buffalo Bills, enter $50 in the “Bet Amount” window and put “+115” 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 “+115” odds into all of the different notations you might see used by a sportsbook. 

The +115 American odds convert to 2.15 decimal odds, 23/20 fractional odds, 1.15 for Indonesian/Hong Kong odds, and -0.8696 Malay Odds. A tool like our moneyline calculator can be a crucial component of a winning betting strategy when evaluating odds at sportsbooks that use different notations.

The “Implied Probability” output tells you that at +115 odds, the Bills have a 46.51% implied probability of winning. If they think Buffalo’s actual chance of winning the game is higher than that, skilled bettors will take that bet.

The “To Win” output yields the profit produced if the Bills win. A winning $50 bet on the Bills yields $107.50 total. ($57.50 profit plus the original $50 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 important difference is that the line is linear. As the odds increase, so does the profit. Both increase infinitely.

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 Bills/Chiefs example from above, if 90% of bets come in on the Chiefs, the sportsbook stands to lose big money if Buffalo wins. 

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 you’ll lose in the long run even if you win exactly 50% of the time. Sharp bettors are sharp because they can win despite this line movement.

How Do I Convert American Odds To Fractional Odds?

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.

How Do I Convert American Odds To Implied Probability?

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.
