Parlay Calculator
What a multi-leg ticket pays, and how often it has to land before that payout is worth taking.
Two legs at these prices pay +264, so the ticket has to land 27.44% of the time just to break even. Both legs carry the book's fee, and tying them together multiplies the two fees rather than averaging them.
Same picks, way bigger payout. Parlaying bets I was making anyway is free upside.
The ticket
What each leg says
Each of those percentages is what the price quotes, not what the leg is truly worth. The gap between the two is the book's fee, and it is already inside every number on this page.
What the ticket becomes
Break-even is the product of the leg chances above, not their average. Because the fee sits inside each one, multiplying the legs multiplies the fee with them — that is the whole reason a parlay is the most expensive way to back the same opinions.
What it pays
This multiplies the legs as if they were independent. Two legs from the same game rarely are — a quarterback's yards and his team's total move together — which is why books price same-game parlays off their own model instead of just multiplying, and usually at a worse number than this page shows. The maths also says nothing about whether any single leg is a good price. A parlay of bad prices is a bad bet at a bigger number.
