Parlay Vig Calculator

Every parlay quietly stacks the sportsbook’s margin — the vig — on top of itself. Build one from real moneyline markets below and see, in dollars, the gap between the true no-vig fair payout and what the book actually pays. That gap is the margin the house keeps.

How the numbers are computed

  • • Real prices only. Legs come from live moneyline markets in our data — you never type odds. A game only appears when both sides are priced by real books.
  • • Honest de-vig. The fair value removes the book’s margin from each leg’s two-sided price (averaging implied probabilities, never the American numbers), then combines the independent legs. If a fair number can’t be computed honestly, it isn’t shown.
  • • One leg per game. Same-game legs move together, so a simple parlay multiplication would overstate the true price. This tool keeps one leg per game so the math stays honest.
