2 of 10 legs
A stake of 10.00 returns 47.75 if every leg wins.
Each leg's price carries its own margin, so a parlay's margin grows with every leg added.
How it works
A parlay, or accumulator, joins several selections into one. Every leg has to win, and the winnings of each leg roll on to the next, so the combined price is the product of the legs’ decimal prices.
The payout is the stake times the combined price and includes the stake; the profit is the payout minus the stake.
Each leg’s price carries its book’s margin, and multiplying the prices multiplies the margins too, so a parlay’s margin grows with every leg. Many books do not allow legs from the same game to be combined this way, since those results are linked.
Worked example
Two legs, one at 1.91 (−110) and one at 2.50 (+150), with a stake of 10.
- Multiply the decimal prices: 1.91 × 2.50 = 4.775.
- The payout is the stake times the combined price: 10 × 4.775 = 47.75, of which 37.75 is profit.
- The combined price implies a 20.9% chance that both legs win.
- Every leg has to win. If one loses, the whole parlay loses.
