Add your parlay legs to calculate combined odds, total payout, and win probability.
Parlay odds are calculated by multiplying the decimal odds of each leg together. For example, a 3-leg parlay with odds of 1.90, 2.10, and 1.75 gives combined odds of 1.90 x 2.10 x 1.75 = 6.98.
If any single leg loses, the entire parlay loses. All legs must win for the bet to pay out. This is why parlays offer higher payouts — the risk is significantly higher than placing each bet individually.
Parlays offer higher payouts but lower probability of winning. Each leg you add multiplies your potential return but also multiplies the risk. For long-term profitability, most sharp bettors prefer straight bets on high-confidence picks rather than multi-leg parlays.
Most sportsbooks allow parlays with 2 to 15 legs. This calculator supports any number of legs. Keep in mind that the more legs you add, the lower your probability of winning — a 10-leg parlay at even odds has roughly a 0.1% chance of hitting.
