Parlay calculator FAQ

What happens if one leg pushes?

Most books drop the pushed leg and pay the parlay at the remaining legs’ odds. Rules vary by book. Remove the leg here to see the new payout.

Is the implied chance the real chance my parlay hits?

It’s the chance the odds imply, with every leg’s vig included. Each leg’s fair price is a little longer; the no-vig calculator shows it.

Does this work for same-game parlays?

It treats the legs as independent. Books price same-game parlays for how the legs relate to each other, so their quoted price will differ. Use the book’s price for those.

How it’s calculated

Convert each leg to decimal odds and multiply them. The product is the parlay’s price.

The formula

Combined decimal
leg 1 × leg 2 × … × leg n
Payout
stake × combined decimal
Profit
payout − stake
Implied chance
1 ÷ combined decimal

Worked example

  1. 1Leg 1: −1101 + 100 ÷ 110 = 1.9091
  2. 2Leg 2: +1501 + 150 ÷ 100 = 2.5
  3. 3Combined decimal odds1.9091 × 2.5 ≈ 4.7727 (+377)
  4. 4Payout on a $20 stake$20 × 4.7727 = $95.45
  5. 5Profit$95.45 − $20 = $75.45
  6. 6Implied chance1 ÷ 4.7727 = 20.95%
