Add up to 10 legs, see combined odds and payout in real time.
Vig compounds across legs — each leg's juice multiplies into the combined price.
How parlay odds are calculated
Convert each leg to decimal odds and multiply them together. A 3-leg parlay at −110/−110/−110 = 1.909 × 1.909 × 1.909 ≈ 6.96×. On a $10 stake: $69.60 total payout ($59.60 profit). Vig compounds — a 3-leg all-−110 parlay has roughly 13% combined vig vs. 4.5% per single.
FAQ
Do same-game parlays work the same way?
No. SGP legs are correlated — a team winning often correlates with the over. Books reduce the odds to account for this, so decimal multiplication overstates the fair SGP price.
What is a teaser?
A parlay where you move the spread/total by a set number of points (6 in football, 4 in basketball) in your favor in exchange for reduced odds. Same math — multiply decimal odds across legs.
Should I use parlays?
Parlays have negative EV by construction — vig compounds. Exception: if you have a genuine edge on each leg and legs are positively correlated, a parlay can have better EV than the individual odds suggest.
What is the maximum payout at most sportsbooks?
Most major US books cap parlay payouts between $1M–$2M. Check house rules before placing high-stake combinations.
