2 The stat sheet
Why the legs multiply
Unrelated legs Parlay odds = odds of leg 1 × odds of leg 2 × …
Three legs at -110 (1.909 each) multiply to about 6.96: $10 returns $69.58. The price implies a 14.4% chance. If you win each pick 55% of the time, your real chance is 0.55 × 0.55 × 0.55, or 16.6%.
Each leg also carries the sportsbook's margin, and the margins compound. The parlay betting guide works out how much.
Every leg you add multiplies the payout and the risk.

Frequently asked questions
How are parlay odds calculated?
Convert each leg to decimal odds and multiply them. Three legs at -110 (1.909 each) give about 6.96, or +596 in American odds.
What does the implied probability of a parlay mean?
It is 1 ÷ the combined decimal odds: the chance the price assumes, margin included. Your real chance is the product of each leg's chance, if the legs are unrelated.
What happens if one leg pushes?
At most sportsbooks, the leg is dropped and the parlay pays on the remaining legs. Check your sportsbook's rules before you bet.
