Parlay / accumulateur calculator
How this calculator works
A parlay (also called an accumulateur or acca) combines multiple individual selections into a single bet. All legs must win for the bet to pay out. The combined cotes equal the product of each individual leg's cotes décimales.
The formula is straightforward: Combined cotes décimales = leg1 x leg2 x ... x legN. Par exemple, three legs at 2.00 each produce combined cotes of 8.00. A 10-unit stake returns 80 units total, or 70 units net profit.
The calculator accepts decimal, American, and fractional input. cotes américaines are converted internally: positive cotes use (n/100 + 1) and negative cotes use (100/|n| + 1). Cotes fractionnelles convert via (numerator/denominator) + 1.
Each leg also carries a win/lose selector. A single losing leg collapses the parlay payout to zero (unless the leg is voided, which removes it from the calculation). Voided legs use a decimal of 1.00 (no change to combined cotes).
The probabilité implicite column shows the raw probability of all legs winning simultaneously: 1 / combined decimal. A 5-leg parlay at average cotes of 1.90 per leg gives combined cotes of roughly 24.76 and an probabilité implicite around 4%. This figure does not account for bookmaker margin, so the true probability will be even lower.
Maximum 12 legs are supported. This matches common sportsbook limits and keeps the combined cotes display readable. At 1win you can build parlays across multiple sports in a single bulletin de pari, mixing football, tennis, basketball, et bien plus.
A common mistake is forgetting that each additional leg multiplies risk, not just récompense. Even adding one 1.50-priced "banker" to a parlay means that selection must also win. The probability of all legs winning falls dramatically with each addition.

FAQ
How many legs can a parlay have?
This calculator supports jusqu'à 12 legs. Most sportsbooks, notamment 1win, allow au moins 12-15 selections in a single accumulateur. The minimum is 2 legs.
What happens if one leg is void?
If a selection is voided (cancelled by the bookmaker), that leg is treated as a 1.00 decimal and removed from the combined cotes. The parlay pays out on the remaining legs.
Are parlay cotes better value than single bets?
Parlays offer higher potential payouts but lower valeur attendue because the bookmaker's margin compounds across every leg. Singles generally have better valeur attendue for skilled bettors.
How do I enter cotes américaines?
Select "American" from the format dropdown, then enter positive values for outsiders (e.g. +150) and negative values for favorites (e.g. -110). The calculator converts to decimal internally.
What is a "same-game parlay"?
A same-game parlay combines multiple outcomes from a single match. The legs are correlated, so true cotes differ from a standard parlay. This calculator models each leg as independent.
