Parlay calculator
Calculate the payout from 2–10 leg prices when a sportsbook multiplies their decimal odds.
Your calculation
A worked example
A $10 parlay with +100 and +150 legs has decimal odds of 2.00 × 2.50 = 5.00. If both win, the return is $50, including $40 profit. The price implies a 20% break-even win rate for the whole parlay; it does not predict the chance of winning.
The math
Combined decimal odds = product of each leg’s decimal odds. Total return = stake × combined decimal odds. Profit = total return − stake.
Common questions
Can I use this for a same-game parlay?
Only to illustrate multiplied prices. A sportsbook may reprice related outcomes; use its actual combined quote. Do not infer joint win probability by multiplying marginal probabilities when outcomes are dependent.
What happens if a leg pushes?
The sportsbook’s rules determine settlement. Some remove a pushed or voided leg; other products work differently. This calculator assumes every entered leg wins.
Why is the displayed break-even rate so low?
A large payout corresponds to a lower price-implied break-even rate. It is not an estimate of how likely the parlay is to win.
