What is a parlay calculator?

There are many different kinds of sports betting calculators out there, and a parlay calculator is used to reveal what your payout would be should you win a parlay bet.

Don’t know what a parlay is? A Parlay is a bet that contains two or more selections, and both of these bets have to win for you to win your bet. The odds will combine in a parlay bet to give you longer odds with less chance of winning, but the potential returns could be significant.

As such, you could use a parlay calculator to see whether your parlay is too risky to bet on, or whether you could potentially add another selection to get better possible returns. A great way to add some extra entertainment to your sporting weekend.

Pros and cons of using a parlay odds calculator

It’s hopefully fairly obvious that a parlay calculator is one of those sports betting tools that you’ll keep coming back to. But just remember that every bet calculator will have their pros and cons. So here are the main advantages and disadvantages of parlay bet calculators:

Pros
  • Free to access
  • Simple to use
  • See your potential parlay returns
  • Evaluate the risk of your parlay
Cons
  • Limited to just parlay bets

How to use our free parlay calculator

We’re proud to reveal our parlay calculator right here on this page. It is completely free to use and you can use it on pretty much any sports under the sun. Here is a quick walkthrough guide for what you need to do:

  1. Select which odds format you want to use.
  2. Pick how many selections you want in your parlay.
  3. Enter your betting stake.
  4. Type in the odds for each selection in your parlay bet.
  5. See your potential payout.
  6. Don’t forget that you can keep tinkering with our calculator to include different odds and different amounts of selections. Plus with the ability to alter your stake at any point, you’ll now have the power to make your perfect parlay.

    Examples of using a parlay odds calculator

    While our parlay bet calculator is pretty easy to use, it never hurts to give you a few examples of this piece of software in action. So, below you will find three examples of how you could use our parlay calculator for different sports with different odds formats.

    American odds

    Let’s imagine that you wanted to bet on a weekend’s action in the NFL. You wanted to bet $10 on the Chiefs, 49ers and the Lions to win their games. Here are the odds for the teams:

    Team to winAmerican odds
    Kansas City Chiefs-300
    San Francisco 49ers-150
    Detroit Lions-200

    From this, the parlay calculator would simply calculate that if your $10 parlay bet won, you would receive a payout of $21.11. Just note that this return doesn’t include your original payout, so you’d receive $31.11 back in total.

    Decimal odds

    As an alternative, you decided that you wanted to make a parlay bet on the weekend’s NBA action. For this, you decided to make a $20 parlay on Cavaliers, Celtics, Magic and Knicks all to win. Here is how their odds would look:

    Team to winDecimal odds
    Cleveland Cavaliers2.00
    Boston Celtic3.00
    Orlando Magic3.25
    New York Knicks4.25

    Now you could type each of these odds into our parlay calculator, set the stake to be $20 and the calculator would reveal that your potential payout would be $818.75.

    Fractional odds

    We’re aware that plenty of people will use fractional odds, so here’s a look at how you might use our bet calculator for fractional odds on a three-leg parlay in the NHL. Here are some examples of the fractional hockey odds you’d want to include in your $5 bet:

    Team to winFractional odds
    Philadelphia Flyers4/1
    Pittsburgh Penguins5/1
    Columbus Blue Jackets8/1

    You’ll notice that each of these teams was a relative underdog and their long fractional odds would combine to give you a potential payout of $1,345. While those returns would be impressive, there wouldn’t be much chance of this parlay actually winning.

    Simple tips for using a parlay bet calculator

    While our parlay calculator is easy to use, your actual parlay bets are probably going to be fairly difficult to win. So here are some handy tips to help you out:

    🧮 Use in Conjunction with Other Bet Calculators

    It’s one thing to know how much you’ll get in returns from your parlay, and it’s something else to know how likely your parlay is to win. This means that you should probably use our parlay calculator with a betting calculator that gives you the odds to implied probability to help you figure out whether that parlay is actually worth taking.

    🎲 Try a Same Game Parlay

    Don’t feel like you just have to use our parlay calculator on different games. After all, you can use it on a same game parlay in just the same way. For example, you could use it on the next Chiefs game for a parlay on Chiefs to win, Patrick Mahomes to throw over 300 passing yards, and for Travis Kelce to score at least one touchdown.

    🏆 Pack Your Parlay with Favorites

    Parlay betting will get a lot easier if you only include favorites in your selection. This is because favorites will have lower odds and these will combine to give you total parlay odds that have a much better chance of winning. The returns might not be so spectacular but a winning parlay is always better than a losing one.

    ✅ Keep Your Selections to a Minimum

    You’ll probably have heard numerous stories about people winning astronomical amounts with 20-leg parlays, but you have to remember that most parlays lose. This is why it’s best to have your parlay contain just a handful of selections. Any more than three legs in a parlay is going to have a tough time winning, and you should use our calculator to play it safe at all times.

    💸 Bet with Small Stakes

    One cool thing about our parlay calculator is that it shows you that you don’t need to bet too much to make an impressive return from a winning bet. This is very good news because responsible gambling is always the best way to bet, and you should remember that parlay betting is risky by nature. So bet with small stakes and keep your sports betting under control.

    Conclusion - Use our parlay calculator in style

    Our parlay bet calculator offers you a supremely simple way to figure out what the combined odds will be and what kind of payout you could be in for. Plus it’s nicely customizable so that you can play around with different selections to balance out risk and potential reward.

    Just remember that parlay betting is hugely risky by nature, and that it’s essential that you bet responsibly when using our calculator. So now you’ve got everything you need to take your bets to the next level, use our calculator to make a smarter parlay.

    Parlay odds calculator FAQ

    🎲 How do you calculate odds on a parlay?

    First of all, you’d need to convert the odds format to decimal odds. Next you would multiply the decimal odds for each selection together. This would give you the total parlay odds.

    💰 What does a $100 four-team parlay pay?

    It depends on what the odds are for each of the selections in the parlay. After all, if you have a parlay packed with odds for nothing but favorites, it would pay out very differently compared to if your parlay was full of bets on rank outsiders.

    📈 What are the odds of winning a 12-leg parlay?

    Again, it depends on what the odds are for each of the 12 selections in the parlay. However, if you have got 12 selections, then you are probably very unlikely to win that parlay bet.

    🥋 Where can I find a UFC parlay calculator?

    Right here on our site. We’ve got a parlay calculator you can use for any sport from UFC and boxing through to football, hockey, basketball, baseball and beyond.

    🔢 Can I use a parlay odds calculator with decimal odds?

    Yes, you can use it with decimal odds, fractional odds and American odds. Perfect for figuring out what your potential returns could be regardless of your preferred odds format.
