Introduction
A parlay is a single bet that links two or more wagers together. To win a parlay, every pick in your bet must win. The risk is higher, but so is the reward. Our Parlay Calculator helps you figure out how much money you can win based on the odds of each leg in your parlay. Just enter the odds for each pick, type in your bet amount, and the calculator will show you the total payout and profit instantly. It works with American, decimal, and fractional odds so you can use whatever format your sportsbook shows. Whether you're combining two teams or building a ten-leg longshot, this tool does the math for you in seconds.
How to Use Our Parlay Calculator
Enter your bet amount and the odds for each leg of your parlay. The calculator will show you the total payout and profit you can expect if every leg wins.
Bet Amount: Type in the dollar amount you want to wager on your parlay. This is the total amount you are risking on the bet.
Number of Legs: Choose how many individual bets (legs) you want to include in your parlay. A parlay must have at least two legs.
Odds Format: Select the format your odds are in. You can pick American (e.g., -110 or +150), Decimal (e.g., 1.91 or 2.50), or Fractional (e.g., 5/1).
Odds for Each Leg: Enter the odds for every single pick in your parlay. Each leg must win for the parlay to pay out, so make sure you type in the correct odds for each one. If you want to evaluate the true odds without the sportsbook's margin, try using a No Vig Calculator to see the fair value of each line.
Total Payout: After you fill in all the fields, the calculator will display your total payout. This is the full amount you would receive back, including your original bet, if every leg of the parlay wins.
Total Profit: The calculator also shows your profit, which is the total payout minus the amount you bet. This tells you exactly how much money you stand to gain.
What Is a Parlay Bet?
A parlay is a single bet that combines two or more individual wagers into one. To win a parlay, every single pick in your bet must win. If even one pick loses, the entire parlay loses. The trade-off for this higher risk is a much bigger payout than if you placed each bet on its own.
How Does a Parlay Work?
When you combine multiple bets into a parlay, the odds multiply together. This is what creates those large potential payouts. For example, if you pick two teams that each have -110 odds, a $10 parlay would pay out around $26.45. Betting those same two games separately at $10 each would only return about $19.09 each if they win.
The more legs (individual picks) you add to your parlay, the higher the potential payout grows — but the harder it becomes to win. A 2-leg parlay is much easier to hit than a 10-leg parlay. You can use an EV Calculator to evaluate whether the expected value of your parlay makes it a worthwhile bet over the long run.
How Parlay Odds Are Calculated
To figure out parlay odds, each leg's American odds are first converted to decimal odds. Then all the decimal odds are multiplied together. The result is your total parlay odds. Your potential payout is simply your stake multiplied by those combined decimal odds.
Here's a quick breakdown of the formula:
- Positive American odds (+150): Decimal odds = (odds / 100) + 1 = 2.50
- Negative American odds (-110): Decimal odds = (100 / odds) + 1 = 1.909
- Total parlay decimal odds: Multiply all decimal odds together
- Payout: Stake × total decimal odds

Tips for Parlay Betting
Parlays are popular because they offer big payouts from small bets, but they are harder to win than straight bets. Sportsbooks make a larger profit margin on parlays, so keep that in mind. Most experienced bettors suggest keeping parlays to 2 to 4 legs to keep your chances reasonable. The more legs you add, the more the odds stack against you. Understanding concepts like percentages and combinations can help you better grasp the probability behind multi-leg parlays.
Parlays work best when used for fun or as a small part of your overall betting strategy — not as your main approach. If you're serious about bankroll management, tools like a Margin Calculator or ROI Calculator can help you track the profitability of your bets over time. Always bet responsibly and only wager what you can afford to lose.
