Parlay Calculator Use

A parlay calculator is an essential tool for sports bettors looking to combine multiple individual wagers into a single ticket. By linking bets together, the potential payout increases significantly, though all "legs" of the bet must win for the ticket to pay out. Use this calculator to instantly see how different odds impact your potential winnings.

Bet Amount (Stake)
The amount of money you are risking on the parlay bet.
Leg Odds
The American odds for each individual game or prop (e.g., -110, +150). You can enter up to 5 legs in this calculator.
Total Payout
The total return you receive if all bets win, which includes your initial stake plus profit.

How It Works

Parlays work on the principle of compounding multipliers. To calculate the total odds of a parlay, the parlay calculator first converts American odds into Decimal odds, multiplies them together, and then multiplies that total by your stake.

Total Payout = Stake × (Decimal Odds 1 × Decimal Odds 2 × … × Decimal Odds N)

  • Negative American Odds: (100 / |Odds|) + 1
  • Positive American Odds: (Odds / 100) + 1
  • Total Profit: Total Payout – Stake

Parlay Calculation Example

Example: You want to bet $50 on a 3-team NFL parlay with the following American odds: Team A (-110), Team B (+120), and Team C (-150).

Step-by-step solution:

  1. Convert Leg 1 (-110): (100 / 110) + 1 = 1.909
  2. Convert Leg 2 (+120): (120 / 100) + 1 = 2.200
  3. Convert Leg 3 (-150): (100 / 150) + 1 = 1.667
  4. Calculate Total Multiplier: 1.909 × 2.200 × 1.667 = 7.000
  5. Calculate Payout: $50 × 7.000 = $350.00
  6. Total Profit: $350.00 – $50.00 = $300.00

Common Questions

What happens if one leg of my parlay pushes?

If a game ends in a tie (a "push"), that leg is essentially removed from the parlay. For example, a 4-team parlay where one game pushes becomes a 3-team parlay. The parlay calculator would simply treat the pushed leg as having odds of 1.00 (Decimal).

Why are parlay payouts so high?

The high payouts reflect the difficulty of winning multiple games simultaneously. Because the probability of winning decreases with every leg added, the math dictates an exponential increase in return.

Can I parlay different sports?

Yes, most sportsbooks allow "cross-sport" parlays. You can use the parlay calculator to combine a Sunday night football game with a Monday night basketball game and a Tuesday baseball game.
