Parlay betting – also known as parley or an accumulator, depending on where you call home – is one of the most popular options in sports betting. Our parlay calculator is the quick and simple way. Decimal odds of 2.0 equates to moneyline odds of +100. To calculate moneyline odds from decimal odds less than 2.0, divide -100 by the difference between the decimal odd and 1. Then round to the nearest whole number. To calculate moneyline odds from decimal odds greater than 2.0, multiply the difference between the decimal odds and 1 by 100. Betting Calculator Before making any bet, it helps to know what you're risking for the expected payout. Enter Your 'Bet Amount' - that's what you're risking, along with the American, fractional or decimal odds. See what your total payout and winnings will be.

What is a Parlay?

A parlay is a bet that combines two or more picks for a larger payout than normal wagers at U.S. sportsbooks. All picks in a single parlay must cover in order to win the parlay bet. Covering five of six games in a six-team parlay counts the same as losing six of six games. Put simply, a parlay requires perfection.

With more risk comes more reward. Two-team parlays (or two-teamers) typically pay 2.6-to-1 and three-team parlays pay 6-to-1. You can add more picks for larger payouts. The payouts above are based on normal-juiced spreads (-110). However, not all spreads are juiced -110. For example, sometimes you will find a side or total -/+105 or -/+120, making parlay calculations a little more difficult. (Learn how to read lines here.)

Moreover, payouts are different when you parlay moneylines, which are particularly common when it comes to betting on the MLB, NHL, and MMA.

For example, look at this hypothetical $10 MLB parlay:

• New York Yankees -210
• Boston Red Sox -165
• Over 8 -120 (Washington Nationals vs. Atlanta Braves)

Enter the price of each pick above (-210, -165 & -120) into the parlay calculator along with the wager size. If you entered everything correctly the payout should read $33.46. The heavy favorites in the parlay decrease the size of the payout.

Now look at this $10 parlay of NFL underdogs:

• Philadelphia Eagles +180
• Indianapolis Colts +250
• New York Giants +365

Again, enter the parlay prices and the wager amount. This time the payout is $445.7 since the parlay consists of big underdogs.

Keep in mind, most sportsbooks do not allow correlated parlays. So you would not be able to parlay the Eagles moneyline and the Eagles spread together, since the Eagles covering the spread increases the odds of the Eagles winning the moneyline. You can often parlay an over/under bet with a spread or moneyline bet from the same game, but there are occasional restrictions depending on the numbers.

The parlay calculator, along with other sports betting tools for NFL, MLB, NBA & more, will help serious and recreational sports bettors alike save time and money as they navigate legal US sportsbooks.

How does the arbitrage calculator work?

What is an arbitrage bet?

An arbitrage (or arb for short) also known as 'surebets', 'surewins' and 'miraclebets' are bet types whereby a bettor wagers on a series of events that guarantees a profit no matter the outcome of a given event, or at worst, guarantees that no money can be lost but money can still be won depending on the result of an event.

Arbitrage bets work by taking advantage of discrepancy in prices of the same event with different Sportsbooks in a way that can ensure the bettor can't lose money no matter the outcome of the event.

What is a sports arbitrage betting example?

Arbitrage opportunities can pop-up in betting markets for a variety of reasons, most commonly being a disagreement in Sportsbook opinions on a certain event.

For example, say an NBA game was being played between the Houston Rockets and the Cleveland Cavaliers. 'Sportsbook A' may open up their market at:

Houston Rockets $1.50 (e.g -200)

Cleveland Cavaliers $2.50 (e.g +150)

And 'Sportsbook B' may open up their market at:

Houston Rockets $1.80 (e.g -125)

Cleveland Cavaliers $2.20 (e.g +120)

You can see here, that there a discrepancy in the odds, or a disagreement between the sportsbooks over the winning chances of each team. In this scenario, the bettor could place $55.55 on the Houston Rockets with Sportsbook B, to receive a payout of $100 if Houston win and the bettor can place $40.00 on the Cleveland Cavaliers with Sportsbook A, to also receive a payout of $100 if Cleveland win.

In this scenario, no matter who wins the game, the bettor has outlaid $95.55, but will receive back $100 no matter what the outcome. This a sports betting arbitrage, an opportunity to guarantee yourself a profit no matter the result (e.g + to your bankroll!)

What are the risks associated with arbitrage betting?

Arbitrage betting can be very profitable as long as you demonstrate patience and capitalise on the many opportunities that arise every day. Where you can lose big amounts with online Sportsbooks is if you outlay large sums on a bet that potentially could be a sportsbook error. That is, imagine there is a bet that is $51 when it should be $1.01 and all other Sportsbooks have it as $1.01. You may then feel the urge to place an arbitrage on the $51 and their opponent at big odds as well on another Sportbook, and outlay large amounts assuming you are in for a massive payday. That is until the Sportsbook cancels the market that had an error (Sportsbooks may be able to do this even after the event has started, read their terms and conditions). You are then stuck in a situation where you have a large amount of money on a huge underdog. Stick to non-error arbitrage opportunties where there is generally a 1-5% guaranteed return. You can however place single bets on the sportsbook errors, because if they get cancelled, you get your money back.
