Combine your picks into one ticket and see exactly what it pays. Enter each leg’s odds in American, decimal, or fractional format, add your stake, and the calculator shows the true combined odds, total payout, profit, and win probability.
Parlay Calculator
Combine multiple legs into one parlay and see the true combined odds, payout, profit, and win probability.
Every leg must win for the parlay to pay. Books build extra margin into parlay pricing, so true combined odds almost always look better than the price on the ticket.
Parlays are simple in decimal odds: multiply the odds of every leg together and you get your combined odds. Three legs at 1.91, 1.91, and 2.00 combine to 1.91 x 1.91 x 2.00 = 7.30. A $100 stake at 7.30 returns $729.62 in total, which is $629.62 in profit. The calculator above does this math for up to 10 legs and shows your combined odds, total payout, and implied win probability.
Here is a full worked example. Say you like three favourites this weekend: the Oilers at 1.91, the Stampeders at 1.91, and an over 5.5 goals prop at 2.00. Enter each leg, set your stake at $100, and the calculator multiplies them into combined odds of 7.30. Your $100 returns $729.62 if all three hit. It also shows the implied probability, which is 1 / 7.30 = 13.7%. That number is worth staring at, because it tells you how often this ticket actually needs to cash for the price to be fair.
When do parlays make sense? They are a reasonable entertainment bet when the stake is small and you accept the long odds, like a Saturday ticket that makes every game worth watching. They can also work in same-game parlays where the legs are genuinely correlated, such as pairing a team win with their star player to score. What they are not is a profit strategy. Every leg carries the book's margin, and that margin compounds with each addition, so the fair value of your ticket shrinks the further you stretch it.
Before you lock in a big ticket, it helps to understand exactly what you are paying for the thrill. Our full guide walks through parlay strategy, correlated legs, and the mistakes that drain bankrolls. And if you want to see how far the offered odds sit from the true odds, our no-vig guide shows you how to strip the book's margin out of any price. Run the numbers first, then decide if the ticket is worth it.
