Understanding baseball parlays: A brief guide
There’s a pretty good chance that you already know what a baseball parlay bet is, but just to ensure we are all on the same page, here is a very brief explanation:
A baseball parlay bet (sometimes known as an accumulator bet or a multi) requires you to place a single bet that combines two or more individual selections. For the bet to be successful, all of your selections have to win. The most common type of baseball parlay bet involves betting on the moneyline or spread of multiple MLB fixtures. However, at some betting sites, you can also place baseball parlays using prop markets, handicaps or totals markets. You will even be able to place same game parlays at certain sites. These bets combine the odds on different markets relating to the same baseball game.
By combining the odds of multiple markets, you can get much longer odds compared to betting on a single selection.

Why you need to use our baseball parlay calculator: Three key benefits
Before I explain exactly how to use our
parlay calculator
for your baseball betting, it is important to outline some key benefits of using the tool. Here are three of the most important:
Weigh up your options
Parlay bets can be slightly tricky to understand. After all, you are looking at multiple markets, so calculating the overall odds is no easy task. And whilst it is true to say that betting sites will give you prices for your parlays, our
betting calculator
enables you to quickly assess different parlay combinations and get accurate prices instantly.
Compare prices at different sites
Baseball betting odds can vary considerably from site to site. Finding the site with the best price for your baseball parlay can make a significant difference to your potential returns. By using our parlay calculator you will be able to quickly compare the prices of identical parlay bets at multiple sites.
Depending on which betting site you are using, you may see betting odds displayed in either fractional, decimal or American format. The below table illustrates how each format works:
| Fractional odds | The ratio of the potential profit against the original stake. For example, odds of 4/1 would mean that a $1 stake would give you $4 in returns if the best was successful. |
| Decimal odds | This displays the amount you would win based on a $1 stake. For example, odds of 4.00 would mean you win $4 if your $1 bet was a winner. |
| American odds | These odds have either a positive or negative symbol in front of them. A negative symbol accompanies the favorite in the market, with a number indicating how much you would need to stake in order to win $100. All other market options have a positive symbol in front of them. In these cases, the number is how much you would win from a successful $100 bet. |

Expert tips for using an MLB parlay calculator
Here are two essential tips to help you get the best possible value from our MLB odds calculator.
🎰 Find your ideal odds format…and stick to it
Choosing the best odds format to use comes down to your individual preference. In the UK, the fractional format is widely used by betting sites, so most bettors find this the easiest format to understand. On the other hand, most other European countries use the decimal format, whilst US sites tend to display odds in the American format. In truth, all three formats give you accurate prices, so it really does come down to which format you are the most comfortable using. But once you have decided that, make sure you always convert your bets to that format when using our MLB odds calculator. Doing this will make life considerably easier when comparing prices at different sites.
Doubles are the easiest parlay bets to understand as they have just two legs. As such, I can highly recommend making doubles bets when you first start using our free baseball parlay calculator. Only move on to wagers with more sections once you are completely comfortable with using the calculator.
Check out our other baseball betting calculators
Aside from the baseball parlay calculator, we also have several other tools that will help you get the best value from your baseball betting:
- Moneyline calculator: Moneyline bets are probably the most popular way to wager on baseball games. And thanks to our moneyline calculator you can check out the implied probability of your bet winning, as well as view your odds in any format.
- Hedge calculator: Hedging your bets involves placing an initial baseball bet, then using another betting site to place a second wager on the same event. By using our
hedge calculator
you can ensure an overall profit.
- Dutching calculator: Dutching is the process of dividing your stake among several selections in the same market. If you use the stakes suggested by the dutching calculator, you can ensure a profit regardless of the market outcome.
- Kelly Criterion calculator: The Kelly Criterion is a strategy for working out your optimum stake. It takes into account the bookmaker’s odds and the true odds of a selection. To use our calculator, just input the odds and the probability of the bet winning. You will then discover the best percentage of your bankroll to use in order to maximise your profit.
Verdict: Use our baseball parlay calculator today
Hopefully, the above guide has demonstrated that not only is our parlay calculator very easy to use, but it is also an essential tool for enhancing your baseball betting. Whilst there are several benefits in using the parlay calculator, the most important factor to remember is that it WILL help you get the best possible value from your MLB wagers.

MLB parlay calculator: FAQs
🧻 What is a parlay bet?
A parlay is a single bet that consists of multiple selections. A baseball parlay will usually involve moneyline bets on two or more fixtures. You can use our baseball parlay calculator to work out your potential returns from these bets.
🧮 How are parlay odds worked out?
Parlay odds are calculated by multiplying each single bet in the wager. This can be a tricky task to complete, which is why our parlay odds calculator is such a useful tool.
🔢 How many selections should I put in my parlay bet?
That is entirely up to you. A parlay bet can have as little as two selections (also known as a double) or as many as 10+ selections. The key thing to remember is that all of your selections should offer good value, as you need every leg to win in order to have a successful bet.
