How does a parlay payout work?
A parlay is a single bet on multiple outcomes — all of them must hit for you to win. The payout is the product of each leg's decimal odds.
parlay decimal = leg₁ × leg₂ × leg₃ × …
So a 3-leg parlay at decimal 2.00 × 2.00 × 2.00 pays 8.00 × your stake. The upside is huge — and so is the variance.
Why parlays favor the house
Each leg already includes the sportsbook's juice (vig). When you string legs together, you compound that juice — a 3-leg parlay of standard -110 legs has a true house edge well above any single straight bet.
The bigger the parlay, the worse the expected value. The math doesn't care how confident you are about each leg — it only knows that each leg has a built-in cost, and multiplying costs through is expensive.
This is why sportsbooks promote parlays heavily, and why sharp bettors mostly avoid them or use them only for genuine +EV situations they couldn't get on the single legs.
What is hedging?
If your parlay is one leg away from cashing, you can bet on the opposite outcome of that final leg to lock in a profit no matter what happens. The hedge calculator above tells you exactly how much to stake to make both outcomes pay the same amount.
Hedging always reduces your maximum profit — you're trading some upside for certainty. Whether that's worth it depends on how much you'd regret a near-miss.
