Calculator
Free Parlay Calculator — Every Odds Format
A parlay chains multiple bets together so every leg must win for you to collect — but the payout multiplies each leg's odds. Enter your stake and each leg's American odds to see exactly what you'd win.
Total payout = what you'd collect (stake + profit). Net profit is what you clear above your stake. The implied probability shows how unlikely this parlay truly is.

Use American format: -110 means risk $110 to win $100; +200 means risk $100 to win $200
How this works
Formula
decimal_total = ∏ decimal_i ; payout = stake × decimal_total
Worked example
Three -110 legs (1.91 decimal each) → 1.91³ = 6.97. A $100 stake returns $696.74.
FAQ
How is a parlay payout calculated?
Convert each leg's American odds to decimal, multiply all decimals, then multiply by your stake.
Are parlays +EV?
Standard parlays compound the book's vig on every leg, making them deeply -EV. Correlated SGPs can be +EV when legs are positively correlated.
What's the max number of legs?
The calculator supports unlimited legs. Most US books cap at 12–25 legs depending on sport.
Does it handle pushes?
Yes — mark a leg as a push and the parlay recomputes at the reduced leg count, mirroring how every US book settles.
Why are my decimal odds in the result different from the book?
Books round decimal odds before display. Parlae uses the exact American → decimal conversion to avoid rounding errors stacking across legs.
