How do parlay odds work?
A parlay multiplies the decimal odds of every leg into one combined number. Convert American odds to decimal first (e.g. +150 → 2.50, −110 → 1.91), multiply them together, then multiply by your stake to get the total payout. Every leg must win for the ticket to cash.
How is a parlay payout calculated?
Payout = stake × the product of each leg's decimal odds. For example, a $100 two-team parlay at −110 and −110 pays about $364 total ($264 profit), because 1.91 × 1.91 ≈ 3.64.
Why are parlays so hard to hit?
The implied probability of a parlay is the product of every leg's probability. Three 55% legs give roughly a 16.6% chance of winning — and the sportsbook's margin compounds with each leg you add. The calculator shows this break-even rate before you commit anything.
What does a 3-team parlay pay?
At standard −110 odds per leg, a three-team parlay pays about 6-to-1 (a $100 stake returns roughly $696 including your stake). Enter your exact odds in the calculator to see the true number for your ticket.
Does the calculator place bets?
No. It only explains the math; you decide what to do with the result.
Can I track the parlay afterward?
Yes. Use the linked parlay tracker to record each leg and your eventual outcome.
