Parlay Calculator: Free & Easy Multi-Bet Optimizer

Last Updated on 12/31/2025
Fact checked by: Meghan

Our parlay odds calculator automatically gives you the total payout for your parlay bet. To use it, you just need to enter the odds for two or more bet selections, plus your total stake.

A parlay bet involves combining two or more wagers into a single combination bet. The odds are multiplied, which obviously gives you a higher potential payout. However, the risk is also greater, because if one of your selections loses, the whole parlay bet loses and won’t get a payout.

How to use the parlay bet calculator

To use our parlay odds calculator, you just need to enter your total stake and the odds for each of your selections. You require at least two selections to make a parlay bet, but it can be more, so you’ll see there is an option to add extra rows on our calculator.

Once you have entered the odds for each selection and your total stake, the calculator will show you your expected return, your profit and the overall odds for the parlay bet.

Inputs

Here is the data that you need to put into this calculator for it to work:

  • Stake - The total amount of money that you would like to bet on your parlay. Note that this is a single figure that will cover all bets combined, not the amount per selection.
  • Odds - You need to enter the odds for each of your parlay selections, of which there must be at least two. Below each selection, there is a button you can click to add another one.

Outputs

Once you have entered all of the above data into our parlay calculator, you will get the following outputs:

  • Expected payout - The total amount you will receive if all of your selections win.
  • Expected profit - The amount of profit you will make if all of your selections are correct.
  • Parlay odds - The overall odds for your parlay bet.

Odds calculator parlay - A step-by-step guide

Here, we’ll take you through the full process of using our parlay odds calculator:

  1. Browse your sportsbook and make your selections
  2. Type in the total amount of money you wish to stake
  3. Enter the odds for each of your selections, adding extra rows if needed
  4. Click the “Calculate” button at the bottom of the page
  5. The expected payout, profit, and overall odds for your parlay bet will be calculated instantly

Example of the parlay odds calculator in action

To give you a working example, we’ve created a same-game parlay bet using an NHL betting line from the DraftKings Sportsbook:

MoneylinePuck LineTotal
Buffalo Sabres:+160+1.5 (-155)0 6.5 (-108)
Toronto Maple Leafs:-192-1.5 (+130)U 6.5 (-112)

Let’s say we want to back the Maple Leafs to win outright and beat the 1.5 puck line, with over 6.5 goals from both teams. If we were to place a $100 bet, here’s how it would look:

Parlay Leg 1 Odds:-192
Parlay Leg 2 Odds:+130
Parlay Leg 3 Odds:-108
Total expected payout:$673.65
Total expected profit:$573.65
Parlay odds:+574

Parlay betting explained

A parlay bet is a type of wager that involves combining two or more single bets into a single bet. This increases the expected payout and potential profit beyond what you would make if you bet on all of these selections individually.

That’s because the odds for all of the selections are multiplied, which as you can see from the example above, raises them significantly. On the other hand, your risk of losing is also increased because every selection must be correct for your bet to win. Basically if you make one incorrect selection, the whole parlay loses.

How a parlay is different from wagering on each bet individually

You might be wondering how a parlay is different from backing each selection individually, and in a way, we’ve already answered that question in the section above, but we’ll explore the concept in a little more detail here.

With a parlay bet, you are effectively bundling multiple bets into a single wager. By doing so, you have the benefit of increased overall odds for your bet because the odds for each selection in your parlay bet are multiplied.

If you were to use the same stake, but place each bet individually, the odds and expected payout would be lower, because you lose the benefit of the multiplication factor. However, as you wouldn’t need all selections to be correct to win, this is a less risky approach.

Parlay calculator odds vs accumulators 

Another question that we’re commonly asked is what the difference is between parlay and accumulator bets. Well, in a nutshell, not much.

The only real difference in definition is that a parlay bet can be any combo bet with two or more selections. Meanwhile, accumulator bets usually have at least three selections, but the two terms are pretty much interchangeable.

Another, and perhaps simpler, way to separate them, is that “parlay” is the preferred term in the US, while “accumulator” or “acca” is more common in the UK and other parts of the world. At the end of the day, however, a parlay is a type of accumulator and vice-versa.

Same-game vs multi-game parlays

In the earlier example, we used our parlay odds calculator for a same-game bet, because all of our selections were for one event. The alternative is a multi-game parlay which, as the name suggests, involves combining selections from multiple different games.

Parlay odds calculator FAQ

⚡ How do you calculate the parlay odds?

To calculate the odds for your parlay bet, convert them into decimal format then multiply them. To get your expected payout, multiply the overall odds by your total stake. Alternatively, the parlay odds calculator here at PromoGuy.us can do it all for you.

✨ Do parlays multiply the odds?

Yes, in a parlay bet, the odds for all of your selections are multiplied together, not added, which is a common misconception. As a result, the expected profit for a parlay bet is higher than it would be if you were to place each bet individually with the same stake. However, the implied probability is much lower, giving you a greater risk of losing.

💎 What are the odds for a six-leg parlay?

There are no fixed or set odds for this type of bet. You need to input the odds for all six legs into our calculator and then enter your stake to get the combined odds. You can test out our parlay calculator now and check out the top UFC betting sites right here at PromoGuy.us.
