Parlay calculator
Updated August 2026
Payout, profit, and the number the ticket doesn't show: the real chance every leg hits.
$364.46
payout on a $100 stake
That last row is the one to sit with: this parlay wins about 27 times in 100.
How the math works
Every leg gets converted to decimal odds, multiplied together, and multiplied by your stake. That's the whole formula, and it's also the whole problem: chances multiply too. Three comfortable 70% favorites chained together survive only about a third of the time, which is why parlaypayouts look spectacular and long-run parlay bettors don't.
The number the ticket hides
A sportsbook shows you the payout in big type and the chance in no type at all. This calculator prints it: “chance every leg hits.” If that number surprises you, that's the conjunction fallacy doing its work, every added leg makes the story feel better and the math worse.
Quick answers
How are parlay payouts calculated?+
Convert each leg to decimal odds and multiply them together, then multiply by your stake. Three legs at -110 each: 1.91 × 1.91 × 1.91 ≈ 6.96, so $100 pays about $696.
What happens if a leg pushes?+
Most sportsbooks drop a pushed leg from the parlay and recalculate the payout with the remaining legs, they don't kill the ticket. Remove the leg here to see the adjusted number.
Why do sportsbooks promote parlays so hard?+
Because the vig compounds. Each leg carries the book's margin, and multiplying legs multiplies the margin, a long parlay can quietly carry several times the house edge of a straight bet.
Is a parlay ever a good bet?+
If every leg is genuinely mispriced in your favor, chaining them concentrates your edge, that's rare. For most people a parlay is entertainment priced accordingly. Know the true chance and decide with open eyes.
