Parlay Calculator
A parlay calculator computes the combined payout of a multi-leg bet where all selections must win. The calculator multiplies the decimal odds of each leg together, then applies your stake to show the total potential payout and profit. Parlays offer higher payouts than individual bets but carry more risk since every leg must hit.
Formula
Parlay Payout = Stake × (Decimal Odds₁ × Decimal Odds₂ × ... × Decimal Oddsₙ)Each leg's American odds are converted to decimal format, multiplied together, then multiplied by your stake. A 3-leg parlay at -110, +150, -105 converts to 1.909 × 2.500 × 1.952 = 9.319, so a $10 bet pays $93.19.

Frequently Asked Questions
How is a parlay payout calculated?
A parlay payout is calculated by converting each leg's odds to decimal format, multiplying them together, then multiplying by your stake. For example, a 2-leg parlay with -110 odds on each leg: 1.909 × 1.909 = 3.644. A $100 bet pays $364.40.
What happens if one leg of my parlay loses?
If any single leg of your parlay loses, the entire parlay loses. This is why parlays carry higher risk than individual bets despite offering larger payouts.
Are parlays a good betting strategy?
Parlays have a higher house edge than straight bets because the sportsbook compounds its margin on each leg. Most professional bettors avoid parlays for this reason, preferring individual +EV wagers. However, correlated parlays (where outcomes are linked) can sometimes offer value.
