Parlay Calculator
Price a straight parlay, teaser, round robin, if-bet, or action reverse in American or decimal odds — with plain-language explanations of every term.
Estimates only — not a guarantee. Sportsbooks price parlays, teaser cards, and reverses with their own odds, rules, and limits. Always confirm the actual price and payout on your betting slip before placing anything.
How this works — straight parlay
A single bet that links two or more picks together. All legs must hit to win. Higher risk, bigger payout.
Every leg must win. The combined odds are all your legs multiplied together, which is why payouts grow fast — and why the win chance shrinks just as fast.
Worked example (editable — load it below): two legs at -110 each combine to about +264. A $100 stake returns $364.46 — your $100 back plus $264.46 profit.

Rounding rules
- All math runs at full precision; rounding happens only when a number is displayed.
- Money (risk, payout, profit) rounds to the cent, half-up.
- American odds display rounds to the nearest whole number (a -110/-110 parlay's true +264.46 shows as +264).
- Decimal odds display to 4 decimal places; implied probability to 1 decimal place.
