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.

Fill in the dollar amount for your bet and the American Odds (for example -110) and calculate the implied probability and the return on the moneyline.:

What Is A Moneyline Bet?

Our odds calculator is perfect for showing you how to calculate potential winnings for all types of sport wagers. It indicates how much you will win based on the odds and total wagered. That way, you’ll know the exact amount you would win prior to placing any picks at your favorite sportsbook.

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

Nfl Betting Odds Calculator Yahoo

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.

Nfl Betting Odds This Week

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.

Advanced Look at NFL Point Spreads

The half-point calculator to the left calculates the fair price for half-point buys in NFL football betting. This tool is helpful for both line shopping and purchasing half points with bookmakers. Regarding line shopping say BetOnline is offering Patriots -4 -110 and Bovada is offering Patriots -3 -140. To determine which is the better bet enter -4 and -110 into the calculator and you’ll see the -3 equivalent of -4 -110 is -3 -142.6. In this example -3 -140 at Bovada is a better bet than -4 -110 at BetOnline.

Understand our calculator uses NFL averages. In cases of games where the over/under betting line is high (say 45.5+) each half point will be worth a little less. So if our calculator tells you -4.5 -105 is the same as -4 -111.5 it might actually only be worth -111. In cases where the total is low (say 40.5 or less) each half point is worth more. In the same example -4.5 -105 might be worth -4 -112 instead of the -111.5 our calculator displays. The point is you’ll need to make small adjustments for games with a lower or higher than average over/under betting total.

Fair Odds (No-Vig): Also understand our calculator deals with fair odds. We do not attempt to determine how much vig was in the moneyline odds entered and propriate an equivalent the same way our no-vig calculator does. In short if the fair odds were -10 -110, we’ll show you the equivelent fair odds for -9.5, -9.0 and -8.5. Creating advanced NFL push charts and doing out the math can lead to much more precise results; however our calculator works extremely well on average and can be a great time saver.

Understanding Buy Point Strategy

Our NFL Half Point Calculator is a great time saver. However, when dealing with point spreads that have juice, or when you desire to be more precise, understanding the math behind half points is helpful. In this article I’ll cover this topic in some depth.

Calculating Half Point Equivalents

Nfl Betting Odds Calculator Cheat

The first thing to understand is that all prices have an implied probability equivalent. For -3 -111 the -3 is the point spread and the -111 is the price. To calculate the implied probability we need to use the formula risk/return=implied probability. To be clear return includes both stake plus win, so for example at -111 a bet of $111 to win $100 has a return of $211 (stake+win). In this example 111/211= 0.5261 which changed to a percentage is 52.61%. This means when betting at -111 you’ll need to win 52.61% of the time to break even and this 52.61% is referred to as the implied probability.

Let’s examine -3 -111 moved to -2.5. All that’s change here is we win instead of push when the favorite wins by exactly three. To calculate the -2.5 equivalent we need to determine exactly how often teams favored by -3 win by exactly 3 points. Using a combination of historical results data and no-vig lines at sharp betting sites I determined this happens about 9.80% of the time. I just calculated one paragraph up that -111 has a 52.61% equivalent. If I add half 9.8% I get an implied probability of 57.51%. I can now go to our odds converter, plug in 57.51% in the implied probability field and see in American odds format this is -135. Therefore -3 -111 and -2.5 -135 have the same expected win/loss.

Why did I use only half of 9.8%? If we were moving from -3.5 to -2.5 I could have used the full 9.8% probability of 3 as we’d of picked up all of that probability. The reason I couldn’t do this is because we were moving from a push to a win (I also would use half when moving from a loss to a push). You see that 9.8% is built half into our line of -3 and half in the opposite team’s line of +3 and for this reason we can only take half the probability.

When should I Purchase Half Points?

The first thing to understand is not all half points are created equal. For example the push probability of 3 is about 9.8% and the push probability of 7 is about 5.72%. These are the two most common margins of victory. Meanwhile -9 only pushes 0.9% of the time, and -12 about 0.44% of the time. Many online sportsbooks sell half points involving the 7 for 15 cents, half point involving the 3 for 25 cents and all other half points at 10 cents each. Under this cost per half point pricing there are only sixteen scenarios where purchasing half points is a better bet than passing on the option to do so.

When to Purchase Two Half Points

• -3.5 purchase to -2.5 by purchasing two half points for 50 cents
• +2.5 purchase to +3.5 by purchasing two half points 50 cents
• -10.5 purchase to -9.5 by purchasing two half points 20 cents
• +9.5 purchase to +10.5 by purchasing two half points 20 cents
• -14.5 purchase to -13.5 by purchasing two half points 20 cents
• +13.5 purchase to +14.5 by purchasing two half points 20 cents
• -17.5 purchase to -16.5 by purchasing two half points 20 cents
• +16.5 purchase to +17.5 by purchasing two half points 20 cents

Nfl Betting Odds Calculator Parlay

When to purchase One Half Point

• -3 to -2.5 by purchasing one half points for 25 cents
• +3 to +3.5 by purchasing one half points 25 cents
• -10 purchase to -9.5 by purchasing one half points 10 cents
• +10 purchase to +10.5 by purchasing one half points 10 cents
• -14 purchase to -13.5 by purchasing one half points 10 cents
• +14 purchase to +14.5 by purchasing one half points 10 cents
• -17 purchase to -16.5 by purchasing one half points 10 cents
• +17 purchase to +17.5 by purchasing one half points 10 cents

Outside of these scenarios when half points cost 25 cents involving point spreads of 3, 15 cents involving point spreads of 7 and 10 cents for all other half points, there are few other circumstances when buying half points makes sense. The one known exception is in cases of -7.5 -115 or +6.5 -115, here purchasing two half points for 15 cents each is slightly better than passing on the option. Just make sure via line shopping you can’t beat the -115 because if you can beat it betting straight would be the better play.
