Dutching Calculator - Odds changed since you placed your last bet? Use this calculator to work out the stakes necessary to guarantee a fixed return irregardless of the outcome. Usually, an odds calculator is an online tool that allows you to determine the possible outcomes of a single bet or multiple bets based on the listed odds and the amount wagered. However, you can find a wide variety of odds calculators here at Odds Coach that go well beyond that definition.
A parlay takes multiple wagers and combines them into a single ticket. For a parlay to pay off, all bets on the ticket must win. If even one pick on a parlay loses, the entire ticket is a loser.
Parlays present a higher risk for bettors, but can also pay off at dramatically higher odds versus single bets. The Gaming Today Parlay Calculator functions as a tool that allows you to see the parlay odds and implied win probability for any combination of bets.

Enter the bet amount and the American Odd for each game in the parlay and your bet amount. If you are not using American odds, enter your decimal odds or fractional odds into this odds calculator.
What Is A Parlay Bet?
Legal sportsbooks allow bettors to put together just about any combination of available bets and play them as a parlay. Any ticket that combines two or more bets into a single ticket qualifies as a parlay wager.
The odds on a parlay bet are calculated as moneyline odds, and most US-facing legal sports use the American odds notation to display moneyline odds. American odds are denoted by a “+” or “-“ in front of the odds number. For example, lines like -110 and +150 use the American Odds notation.
Calculating Payouts From Positive Moneyline Odds
To calculate “+” American odds, take the odds number and divide by 100, then multiply that by the size of the bet.
A $50 bet at +150 odds, for instance, is calculated as 150/100 (which yields 1.5), multiplied by $50 (1.5*$50=$75). A winning $50 bet at +150 odds would return $125 total to the bettor ($75 profit plus the original $50 bet.)
Calculating Payouts From Negative Moneyline Odds
To calculate “-“ odds, divide 100 by the odds number, then multiply by the amount of the wager.
A $50 bet at -110 odds would be calculated as 100/110 (without the “-“ for the 110 odds), which yields 0.909. You then multiply that by the size of the bet (0.909*$50=$45.45). A $50 winning bet at -110 odds would return $95.95 to the bettor ($45.45 profit plus the original $50 bet).
Decimal Odds
American odds aren’t the only notation sportsbooks use to display moneyline odds. Decimal odds represent another common way to display moneyline odds. Odds notations like 1.20 and 10.00 are moneyline bets represented with decimal odds.
To convert “+” American odds into decimal odds, take the odds number and divide by 100, then add 1. Converting +150 to decimal odds is executed as (150/100)+1. That reduces to 1.5+1, which equals 2.5. So 2.5 decimal odds are equivalent to +150 American odds.
Converting “-“ odds to decimal odds requires dividing 100 by the odds and subtracting that quotient from 1. The -110 are converted as 1-(100/-110), which reduces to 1-(-0.909) and solves as 1.909. So -110 American odds convert to 1.909 decimal odds.
To calculate the return on a bet using decimal odds, multiply the wager by the odds. For example, a $50 bet at 1.909 decimal odds returns $95.45 to the bettor. To calculate profit, subtract the amount of the wager from this product ($95.45-$50=$45.45).
Favorites Versus Underdogs
The favorite in a game is the team with the higher implied probability of winning. Favorites are denoted by “-“ odds when using American odds. Favorites win more often overall, but pay out less on a win compared to underdogs.
Underdogs are the team with the lower implied probability of winning and are denoted with “+” odds. When making a parlay bet, combining multiple underdogs can produce potentially huge payouts, but the implied winning probability of such a ticket is low.
Implied Probability
The Gaming Today Parlay Calculator allows you to take any number of moneyline bets, input them into the calculator, and see both the payout odds and implied probability of winning. Implied probability can be derived from any moneyline number.
Implied probability for “+” odds is calculated as 100/(“+” American odds + 100)*100. So for instance, the implied probability of +150 moneyline odds is calculated as 100/(150+100)*100. That reduces down to 40, so a bet with +150 odds has a 40% implied probability of winning.
For “-“ odds, the implied probability is calculated as “-” odds / (“-” odds + 100)*100. Putting -110 odds into that equations yields 110/(110+100)*100, which solves to 52.38. So a -110 American odds bet translates to a 52.38% implied probability of winning.

Finding Value In A Parlay Bet
The implied probability of any bet, including parlays, can be used by astute bettors to find value in a sports wager. Finding value means making bets on teams that have a better chance of winning on the field versus what the implied probability indicates.
When trying to find value in a parlay bet, you must evaluate whether all of the bets on the tickets have a better chance of winning than the implied probability of the entire ticket. Keep in mind, however, that all of the bets on a ticket have to win for the parlay to win.
What Is A Parlay Calculator?
The Parlay Calculator will help you determine the expected payout for a given moneyline parlay bet. Parlay bets are a single bet that links together two or more individual wagers and are dependent on all of those bets winning.
Parlays have higher payoffs than placing each individual wager since the difficulty of winning it is much higher. If any of the bets in the parlay lose, the entire parlay loses. Any plays in that “pushes” or ties, then the parlay eliminates that bet from the parlay and is recalculated based on fewer bets in the parlay.
How The Gaming Today Parlay Calculator Works
The math calculating a parlay gets more difficult with each new bet, but if you understand how moneyline calculations work, it becomes just a matter of a couple of extra steps. Let’s take a set example.
Bet 1: -110
Bet 2: -150
Bet 3: +100
To calculate the payout we need to evaluate each set of odds into decimal odds, multiply the result, and subtract a factor of 1. Remember from the moneyline calculator article, that negative odds and positive odds need to be evaluated differently. Here is what that looks like:
Bet 1: (-1*-110+100)/-1*-110 = 1.909
Bet 2: (-1*-150+100)/-1*-150 = 1.666
Bet 3 (100+100)/100 = 2
Next, we multiply the three results and subtract 1 from the total, and multiply by the Bet Amount:
(Bet 1 * Bet 2 * Bet 3 -1) * Bet Amount = Parlay Payout
Which looks like:
(1.909 * 1.666 * 2 -1) * $100 = $536.08
Not a bad result, but don’t be fooled: the multiplication here is also consistently multiplying the risk. The implied probability of the above occurring is 13.59%. Those odds would look like a +536 longshot bet. Now let’s look at the event where Bet 2 is a push:
Bet 1: (-1*-110+100)/-1*-110 = 1.909
Bet 2: (-1*-150+100)/-1*-150 = 1.666
Bet 3 (100+100)/100 = 2
(1.909 * 2 -1) * $100 = $281.80
In the above case, the push is removed entirely from the outcome and the odds adjust accordingly. Below is a basic parlay chart for -110 odds for each bet:
This graph shows the profit as the number of bets in a parlay increase, based on a total $100 bet.
What Is Line Movement?
Sportsbooks set the lines on each game to produce enough bets on both sides of the line to allow the house to make money. If 100% of bets come in on the favorite of a given game, for example, the sportsbook loses massively if the favorite wins.
To balance that out, the sportsbook sets lines that encourage plenty of bets for both the favorite and the underdog. If too much money starts to come in on one side of a bet, the sportsbook will adjust the line in hopes of prompting more bets on the other side.
Note that the house sets betting lines in a way that allows the sportsbook to take vig, aka house cut. For example, totals bets often set the line at -110 on both sides, though a true even money bet would set the odds at +100 for both the under and the over.

How To Use An Odds Calculator
Odds calculators help you determine what your payout would be if you were to make a specific bet. You can plug in your desired bet amount and the odds a sportsbook gives you, then the calculator will tell you what you’d win if the bet hit.
Odds calculators are particularly useful if you’re trying to decide between a number of sportsbooks for a specific bet. Different sportsbooks offer different odds, so you can maximize your potential payout if you search for the best odds and use a calculator to help you decide your best path.
We have a number of odds calculators on our site for various types of bets, including moneyline, parlay, and futures calculators.
Moneyline Odds Calculator
Because moneyline bets are on a single team to win, it’s the easiest calculator to use. Here’s how:
- Type your desired bet amount (in USD) into the proper field.
- Type the odds as the sportsbook lists them.
- The calculator will autofill the rest of the fields and show you how much the bet would pay if you were to win.
Parlay Odds Calculator
If you’re a fan of parlay bets (which combine multiple wagers into one), you can use a parlay-specific calculator. Here’s how:
- Plug in your desired bet amount in USD in the proper field.
- Enter the odds for each individual leg of the parlay into the moneyline fields. Note that they don’t have to be moneyline bets; just pull the odds from whichever bets you intend to use as part of the parlay.
- Click “calculate” for your combined parlay odds and potential payout.

How Sports Betting Odds Are Calculated
If you’re new to sports betting, chances are you’ve been confused by how odds work. They can be complex to understand for a newcomer, but once you understand the basics, you’ll be betting like a pro.
The first thing to know is that odds are typically calculated based on how many people are betting on a certain outcome. So if the Kansas City Chiefs are favored by many bettors to win over the New York Giants, the Chief’s odds to win will increase as bettors place wagers on that outcome.
Other factors can come into play, such as team record, past performance, injured players, etc., but bets placed are the biggest determining factor in most cases.
How To Read Odds And Determine Payouts
Sportsbooks display odds as a positive and negative numbers, and those odds tell you how much you’ll win if your bet hits. Here’s a scenario to help you understand how they work.
- Chicago Bears +200
- Tennessee Titans -230
This setup is showing a moneyline bet, which means those are the odds for either team to win outright. Whenever you see a negative number (in this case -230), that means that team is favored to win the match and a bet of $230 would win you $100. The positive number (+200) shows which team is the underdog and tells you how much you would win if you placed a $100 bet.

College Sports
NCAA sports are somewhat of a mixed bag. They’re usually available to bet on, but some states put specific restrictions on them.
In Illinois and New Jersey, for example, you can only bet on college match-ups that don’t include a school from the state you’re betting in. So Illinois fans can’t place wagers on games including Northwestern or the University of Illinois, while New Jersey bettors can’t wager on Rutgers or Princeton match-ups.
International Sports
Globally popular sports like soccer, rugby, and cricket are available for betting in most legal markets with few restrictions.

Esports betting runs the gamut from completely legal to prohibited to left out of legislation completely. Before you place an esports bet, make sure you check that it’s legal in your state.
Non-Sporting Events
Elections and awards shows are among the most popular non-sporting events on betting platforms. Not every state allows betting on them, though. It varies by state, so check your local laws or betting sites for more information.
Legal Online Sportsbook Apps In The US: Common Questions
Not everywhere. In 2018, the Supreme Court struck down the Professional and Amateur Sports Protection Act. Rather than legalizing sports betting across the board, it put the issue in individual states’ hands.
Many states have legalized online sports betting, and more are working on legislation to do so. While it’s not legal everywhere, sports betting is swiftly making its way to more US markets beyond the two dozen that already allow it.
You can find sports betting odds by visiting the sportsbook website of your choice. They will usually display their odds without requiring you to log in or create an account.
Online resources also exist that compare and contrast the odds at top sports betting platforms. Sports news sites, including CBS Sports and NBC Sports, will often list the lines as well.
Using an online odds calculator or by calculating the odds manually. Gaming Today has several odds calculators to choose from.

DraftKings, FanDuel, and BetRivers have the consistently best odds out of all the online sportsbooks in the US market. However, that isn’t always true. In many cases, other sportsbooks will have better odds. The most successful sports bettors compare and contrast different options before placing a bet for that very reason.
Range of factors. Sports betting odds are calculated based on a variety of things including injuries and trades, current team form, the weather, and beyond. How players are betting also determines the odds, which is one of the reasons why you’ll see significantly different odds at one sportsbook versus another.
An odds calculator helps sports bettors determine their betting strategy. The most basic is a moneyline odds calculator that tells you how much you’ll win based on your bet and the odds. However, different odds calculators have different purposes, such as comparing futures, identifying arbitrage, and more.
