AI parlay odds calculator: what the slip pays and what it really needs
parlay calculator: enter up to six legs — combined American odds, the payout on your stake, the implied chance of hitting, and the fair payout at no vig.
Nothing is worked out until you tap. Five runs a day, unlimited with a Velvet seat.
How it works
Parlay odds are the legs' decimal odds multiplied. Every leg carries the book's hold, so the hold compounds — which is why parlays pay less than fair, and more legs means less.

About the parlay calculator
A parlay multiplies the decimal odds of every leg into one price, and every leg has to win. Enter each leg's odds and your stake to see the combined odds, the payout and the chance the whole ticket hits. A two-leg parlay of -110 bets pays about +264.
What happens if a leg pushes?
Usually that leg drops out and the parlay pays at the odds of the legs that are left.
