12 team parlay payout
A 12-team parlay pays only if all 12 legs win. At -110 on every leg, which is the standard price for a spread or a total, a 12-leg parlay returns 2343.79 times the stake: $234,379.33 on a $100 bet, of which $234,279.33 is profit. In American odds that is +234279, and the price implies a 0.043% chance of the ticket landing.
The calculator on this page starts with 12 legs already in it. Change any price, mark a leg as a push, or set your own stake.
What a 12 team parlay pays
Every leg at the same price, which is the case the payout question is usually about:
| Every leg at | Parlay odds | Decimal | $10 returns | $100 returns | Implied chance |
|---|---|---|---|---|---|
| -200 | +12875 | 129.75 | $1,297.46 | $12,974.63 | 0.77% |
| -150 | +45839 | 459.39 | $4,593.94 | $45,939.37 | 0.22% |
| -120 | +144077 | 1441.77 | $14,417.74 | $144,177.41 | 0.069% |
| -110 | +234279 | 2343.79 | $23,437.93 | $234,379.33 | 0.043% |
| +100 | +409500 | 4096.00 | $40,960.00 | $409,600.00 | 0.024% |
| +150 | +5960364 | 59604.64 | $596,046.45 | $5,960,464.48 | 0.0017% |
| +200 | +53144000 | 531441.00 | $5,314,410.00 | $53,144,100.00 | 0.00019% |
| +300 | +1677721500 | 16777216.00 | $167,772,160.00 | $1,677,721,600.00 | 0.000006% |
Mixed prices multiply the same way. Put them into the calculator above rather than reading a row off this table.
Every sportsbook caps what a single ticket can pay, and the longer rows above run past what most of them will settle. The cap lives in the book's house rules rather than on the bet slip, so a ticket priced above it pays the cap and not the number here. Worth checking before staking a long parlay on a big payout.
The odds of a 12 team parlay
Multiply the 12 decimal prices together and you have the parlay's decimal odds. Flip that number over and you have the chance the price implies: 0.043% at -110 across the board.
That is the sportsbook's number, not a forecast. It already carries the book's margin, and the margin compounds on every leg you add.
What twelve legs costs
A market priced -110 on both sides implies 52.38% for each outcome, which adds to 104.76%. The excess over 100% is the book's margin. Take it out and each side's fair chance is 50%.
So if every leg in a 12-leg parlay is a coin flip once the margin comes out, the ticket lands 0.024% of the time while the price implies 0.043%. A dollar on it is worth 57.2 cents, or -42.8% expected value.
That number is what the margin costs at this length. It assumes the legs are independent, which legs from different games are and legs from the same game are not.
Is a 12 team parlay worth it?
The payout above is arithmetic, and every calculator agrees on it. Whether the ticket is worth buying depends on the real chance those 12 legs land together, which no price can tell you.
The bet checker grades each leg against thousands of simulated runs of the games the legs live in, combines them into one probability for the whole ticket, and sets that against the price. Sometimes the answer is that the price is generous. On a 12-leg ticket it usually is not.
