How to Use Our Free Parlay Calculator
Our parlay calculator works for any combination of American odds — point spreads, moneylines, totals, and props. Enter your legs, set your stake, and get instant parlay odds and payout. No account needed.
1
Enter your first leg's odds
Type the American odds for your first pick (e.g., -110 for a spread, +150 for an underdog moneyline). The parlay calculator accepts any valid American odds format.
2
Add more legs
Click "Add Leg" for each additional pick. Our parlay calculator supports up to 12 legs — matching the maximum most US sportsbooks allow.
3
Set your wager amount
Enter how much you want to bet. The calculator updates your potential payout instantly as you type.
4
Read your parlay results
See total parlay odds (American), exact payout in dollars, total profit, and the combined win probability across all legs.
The parlay calculator converts each leg from American odds to decimal format, multiplies them together to get true parlay odds, then applies your stake to show the exact payout — including the sportsbook's house edge. Use it before locking in any multi-leg bet to know exactly what you stand to win.
What Is a Parlay Bet?
A parlay (also called an accumulator) is a single bet that links two or more individual wagers together. To win the parlay, every single leg must win. If even one leg loses, the entire parlay loses. In return for this increased risk, successful parlays pay out much more than individual bets would combined.
For example: If you bet $100 on a 3-team parlay where each team is -110, and all three teams win, your payout would be approximately $596 — a profit of $496. If you had placed three separate $33 bets at -110 odds and all won, you'd profit only about $90 total.
How Parlay Odds Are Calculated
Parlay odds are calculated by converting each leg's American odds to decimal format, then multiplying all the decimal values together. For example:
Leg 1: -110 → 1.909
Leg 2: +150 → 2.500
Leg 3: -120 → 1.833
Total: 1.909 × 2.500 × 1.833 = 8.74 (decimal) = +774 (American)

Types of Parlay Bets You Can Calculate
Standard Parlay
Two or more picks from different games. Most common format — use this parlay calculator to price any mix of spreads, moneylines, and totals across any sport.
Same-Game Parlay (SGP)
Multiple picks from one game (props + spread + total). Available at DraftKings, FanDuel, and BetMGM. Correlation rules may cap payouts.
Round Robin Parlay
Generates all possible smaller parlays from your picks. A 4-team round robin of 2-teamers creates 6 separate parlays — more coverage if one leg loses.
Teaser Parlay
Move point spreads in your favor (typically 6 pts in NFL/NBA) in exchange for reduced parlay odds. A 2-team 6-point NFL teaser pays around -120 vs +260 standard.
