How the 12-Leg Parlay Calculator works
What does a 12 team parlay pay?
A 12 team parlay with every leg at -110 pays +234279: $23,437.93 back on a $10 bet ($23,427.93 profit) and $234,379 on $100. To get there, convert each leg to decimal odds (-110 is 1.909), multiply all 12 together for 2343.79, then multiply by your stake.
True odds of a 12 leg parlay
A -110 line on both sides is a coin flip once the vig comes out, so the fair chance all 12 legs win is 0.5 to the power of 12: 0.024%, or 1 in 4,096. The price you pay implies a higher 0.043%, because each -110 leg charges you as if it wins 52.4% of the time.
How much the book holds on a 12 leg parlay
If every leg is a true coin flip, the book expects to keep 42.8% of every dollar bet on a 12 leg parlay at -110, compared with 4.5% on one straight bet. The vig compounds with each leg, which is why books promote parlays so heavily.
At 12 legs the book keeps almost half
Twelve -110 legs combine to +234279. The fair chance of all twelve hitting is about 1 in 4,096, and the book's expected hold is 42.8%, so close to half of every dollar bet on these tickets stays with the house. A $10 ticket would return $23,437.93, though many sportsbooks cap single-parlay payouts below what a large stake would win.
