How Does a Parlay Calculator Work?
A parlay calculator estimates the combined odds, potential payout and profit for a parlay. Enter your wager and the odds for each leg, and the calculator converts the prices to decimal odds, multiplies them together and applies the combined price to your wager.
This free parlay calculator accepts American odds such as +150 and -120, along with decimal odds such as 1.91. You can use it for moneylines, spreads, totals, player props and other standard betting markets.
How to Calculate Parlay Odds
To calculate parlay odds manually, first convert every leg to decimal odds. Multiply those decimal prices together to get the combined parlay price. The calculator does those conversions automatically and displays the result as combined American odds.
For example, three legs priced at +150, -110 and +200 are converted to decimal odds and multiplied together. Adding another leg increases the potential return, but every leg in a standard parlay must win for the parlay to cash.
How to Calculate a Parlay Payout
A parlay payout is the total amount returned if every leg wins. Multiply the combined decimal odds by the wager to calculate the potential payout. Subtract the original wager from that amount to find the potential profit.

Moneyline Parlay Calculator
You can enter American moneyline prices directly into the calculator. For example, add +120, -135 and +160 as separate legs, enter your wager and calculate the combined parlay odds, payout and profit. The same calculator also works when a parlay mixes moneylines with spreads, totals or props.
Boxing Parlay Calculator
The calculation is based on the odds entered rather than the sport itself. Use the calculator for football, baseball, basketball, hockey, soccer and other supported markets.
Parlay Payout Examples by Number of Legs
The calculator automatically adapts to the number of legs you enter. A 2-leg, 3-leg or 6-leg parlay uses the same process: convert each price, multiply the decimal odds together and apply the combined odds to the wager. Use the Add Leg button to model the exact parlay you are considering.
American Odds vs Decimal Odds
American odds show how much profit a positive price returns on a $100 wager, or how much must be risked at a negative price to profit $100. Decimal odds show the total return for each $1 wagered. This calculator accepts both formats.
- +150 means a $100 wager would profit $150.
- -120 means $120 would be risked to profit $100.
- 2.50 decimal odds means each $1 returns $2.50 total.
Common Parlay Betting Mistakes
- Adding too many legs only to chase a larger payout.
- Confusing the total payout with the profit.
- Ignoring how much each additional leg reduces the chance that the entire parlay wins.
- Not comparing odds across sportsbooks.
- Assuming a larger potential payout automatically means better value.
