How to use the parlay calculator

Start by entering the odds for each leg of your parlay. Then add your stake. The calculator will combine the odds and show your potential profit, total payout, and final parlay odds.

You can add or remove legs to compare different versions of the same bet before deciding whether the risk is worth the return.

What the parlay calculator shows you

The most important numbers are your combined odds, your potential profit, and your total payout. Combined odds show the final price of all your picks together. Potential profit is what you would win on top of your stake. Total payout is your stake plus your profit.

Remember that a parlay only wins if every leg wins. If one pick loses, the whole ticket loses, even if every other leg was correct.

Introduction to parlay calculators

Parlays are among the most popular types of bets placed by people who wager on sports. Data displays that on average, a typical sports bettor will wager between 25% and 36% of their total bankroll on parlay plays. However, parlay wagers make up a much larger portion of the total bets played. Estimates are that six out of every 10 sports wagers placed are some form of parlay play.

On the surface, it’s entirely understandable why parlays are so popular with sports bettors. In essence, they are the sports betting version of playing the lottery. With parlay betting, you are making a small investment with the hopes of realizing a major score. This gives the small-time gambler a chance to score a big-time payday.

However, the reality is that just like the lottery, the odds of you hitting it big are remote at best. The trade-off you are making is that every added leg in your parlay makes the ticket harder to hit. The real question is whether the potential payout justifies the risk. And that’s where parlay calculators come into vogue. Similar to standard betting odds calculators, they handle odds conversions and basic math. However, their real value lies in breaking down the payout dynamics of multi-leg wagers.

Use our parlay calculator to work out your combined odds, potential profit, and total payout before placing a multi-leg bet. Add each leg’s odds, enter your stake, and the calculator will show what your parlay would return if every pick wins.

How parlay betting works

Before getting into the details of how to work a parlay odds calculator, you first need to be certain that you understand what a parlay wager actually is. Honestly, it's a simple wager that seems more complicated than it really is. With a parlay bet, you are combining multiple wagers into one large ticket. Every separate outcome on the parlay card is linked to form a single bet. The catch is that if one leg of your parlay fails to come in, the entire ticket comes crashing down. Then again, should all your picks hit, the payout you will gain is going to add up to a far greater total than you would make by betting each outcome individually.

Types of parlay bets

There are basically three styles of parlay bets in existence at online sportsbooks. There are traditional parlays, multi-sport parlays, and same-game parlays. You can add as many legs to a parlay play as the sportsbook allows. Some will go as high as 20 different plays. But remember, all of them must come in for your parlay to win. Let's look at how each of these plays works.

Traditional parlays

In a standard parlay play, you will be taking a selection of events from the same sport and packaging them into one combo wager. You've probably all played in an NFL pool, which asks you to select the winners of multiple games. That's basically how a parlay calculator for NFL games works. You take several games, pick a winner, and parlay all the outcomes into one giant wager. Say you pick the Cincinnati Bengals to beat the Cleveland Browns, the Minnesota Vikings to beat the Chicago Bears, and the Los Angeles Rams to beat the San Francisco 49ers on the same NFL Sunday. That's a traditional parlay.

Multi-sport parlays

Putting a twist on the standard parlay play, multi-sport parlays enable you to package outcomes in a variety of sports into a parlay. You could take that same Bengals over the Browns play in the NFL, combine it with a Minnesota Timberwolves win over the Miami Heat in the NBA, and a Los Angeles Kings win over the Anaheim Ducks in the NHL.

Same-game parlays

The newest of parlay options, these bets work just as the name suggests. You'll be selecting a combination of outcomes from one game and putting them into a parlay play. Let's say you start with that same Bengals win over the Browns play. Then you add in Bengals QB Joe Burrow to go over 1.5 TD passes, and take the over 57.5 points on the total for the game. That's a same-game parlay.

How parlay betting calculating works

As you are in the process of assembling a parlay card, you'll want to know whether the risk is worth the prospective reward. That's where parlay betting calculators come in handy. The tools of a moneyline parlay calculator determine your prospective payout in a matter of moments. Simply input each specific bet on your parlay card, along with the amount of your wager. Then let the Vegas parlay calculator do its job. It will generate a total payout, based on the amount you're betting, should all of your individual plays pay off.

Parlay Calculator Example

Let’s take a baseball parlay calculator example to show how the parlay calculator works. Suppose at the start of the MLB season, you picked the New York Yankees (+350), Seattle Mariners (+150), Milwaukee Brewers (+200), and Detroit Tigers (+125) to win their respective division titles. You decide to wager $100 on this parlay. Now, punch all of those odds into the calculator, along with your stake. After factoring in all the moving parts, the calculator would return the following data:
  • Bet Amount: $100
  • Parlay Odds: +7494
  • To Win: $7,493.75
  • Total Payout: $7,593.75
If you wanted to calculate this on your own, the easiest method is to convert the American odds to decimal odds. So +350 becomes 4.5, +150 becomes 2.5, +200 becomes 3.0, and +125 becomes 2.25. Next, multiply all four of those odds:
  • 4.5 x 2.5 x 3.0 x 2.25 = 75.9375
Next, multiply the multiplier by your bet amount:
  • 75.9375 x 100 = 7,593.75
That's your total payout on a winning parlay play via this MLB parlay calculator.

Parlay betting strategies

For sure, this is a high-risk play. But it offers a high return. You can lower the risk by going with heavy favorites, but that will also shrink your return. Or you can mix in some favorites with some longer shots to try to create a larger payout. You could really raise the stakes by rolling a bunch of underdog plays together, but again, the chances of this parlay hitting, while extremely lucrative, would be highly remote. Many bettors view parlays as a way to squeeze extra value out of heavy favorites. It's a method that, when it works, can be surprisingly rewarding. When it comes to betting parlays, you have to be able to answer one question: Can you stomach the risk? With parlays, every added leg raises the odds, and the difficulty. A five-leg parlay where you hit four out of five still pays nothing.
