Parlay Calculator
Enter each leg's odds and your stake. You get the total payout, your profit, the combined parlay price and the implied win percentage. American or decimal odds, any sport, up to 15 legs.
Legs
3 legsSplits the legs above into every smaller combo, so missing one leg doesn't sink the whole ticket. Stake is per ticket.
One leg from cashing? Find the bet on the other side that locks the same profit whichever way it lands.
Work backward: enter what you want to win and your stake to see the combined odds you need - and roughly how many legs that takes.
Enter both sides of one market to strip out the book\u2019s margin and see the true price - plus exactly how much vig you are paying.
Standard parlay payouts
What a parlay returns when every leg is priced at the standard -110 (the typical price on a point spread or game total), per $100 staked. Use it as a quick gut check.

How it works
The math
Each leg's odds are converted to decimal, multiplied together, then multiplied by your stake. That is the whole formula. A 3-leg parlay at -110, -110, +120 becomes 1.909 x 1.909 x 2.20, or about 8.02 in decimal, so $10 returns roughly $80.
American or decimal
Type -110, +150, or 1.91. The calculator reads either format. American numbers need the sign for underdogs (+) and favorites (-); decimals just need the point, like 2.50.
Implied win chance
This is 100 divided by the combined decimal odds. It is the break-even rate the parlay needs to clear over time, and it already bakes in the book's margin, so treat it as a reference, not a prediction.
More legs, bigger swing
Every leg you add multiplies the payout and shrinks the odds of all of them landing. Longer parlays also stack more vig, which is why books market them so hard.
