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.

Moneyline Calculator

Moneyline betting is pretty straightforward and involves betting on who is going to win. Unlike points spread which is based on who wins and by how much, a moneyline bet does not consider points spread. Though this is probably considered the simplest type of bet, it can be confusing to understand how payouts work if you don’t know how to read. In the world of sports betting, a money line bet is simply betting on which team you expect to win. It doesn’t have anything to do with a spread. You may also see a money line bet listed as “Money Line” or “ML” in different spaces. Money lines are represented in negative and positive values. To put it simply, a money line wager is betting on who will win the game. Unlike the points spreadand totals bets, the money line is in no way concerned with how many points are scored or the margin of victory. You’ll know you’re looking at a money line when you see a plus (+) sign next to the underdogand a minus (-) next to the favorite.

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:

American Odds

How To Read A Moneyline

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:

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.

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.

Moneyline Nfl

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.

In the world of sports betting, a money line bet is simply betting on which team you expect to win. It doesn’t have anything to do with a spread. You may also see a money line bet listed as “Money Line” or “ML” in different spaces.

Money lines are represented in negative and positive values.

Negative money line: -145, -220, or anything similar

When you see a minus (-) sign in front of a price, it shows you that team is the favorite to win the game.

That number also indicates how much money you need to bet/spend in order to win $100.

For example, a -220 money line means you need to bet $220 in order to win $100 provided the team you bet on actually does win.

Heavy favorites are known in sports betting as a “chalk” pick. A heavy favorite usually has a number pushing +300 or more. Here, you’re wagering a lot on the favorite to win a little. Don’t assume that a heavy favorite, or chalk pick, is a guaranteed winner…

Positive money line: +145, +220, or anything similar

When you see a plus (+) sign in front of a price, it shows you that team is the underdog. Higher numbers like +400, +500, +5000, etc. represent how much of an underdog the team is in the game. The higher the number the more likely the team is expected to lose in the eyes of the oddsmakers.

The number also indicates how much money would win in comparison to every $100 you wager.

For example, a +150 money line means you would win $150 for each $100 wager you place should that team win the game.

Money line examples:

Lets use an NFL example here:

New England Patriots -240

Miami Dolphins +220

To bet the New England Patriots to win on the money line, you would need to spend $240 on the bet for a chance to win $100 if the Patriots beat the Dolphins. Your return would be $340 – the original $240 stake (bet) and the $100 bet profit.

To bet the Miami Dolphins to win on the money line, you would spend $100 on the bet for a chance to win $220 if the Dolphins, as the underdog, beat the Patriots. Your return would be $320 – the original $100 stake (bet) and the $220 profit.

In both situations, it doesn’t matter if the team you bet on wins by one point or 100 points. You’re purely betting on the team you believe will win the game. As Al Davis said, “Just win, baby.” That’s exactly what you’d be looking for out of your selection. It doesn’t have to be pretty, it just has to happen or your original stake is lost.
