Parlay / acumulator calculator
Cum funcționează acest calculator
A parlay (also called an acumulator or acca) combines multiple individual selections into a single bet. All legs must win for the bet to pay out. The combined cote equal the product of each individual leg's decimal cote.
The formula is straightforward: Combined decimal cote = leg1 x leg2 x ... x legN. For example, three legs at 2.00 each produce combined cote of 8.00. A 10-unit stake returns 80 units total, or 70 units net profit.
The calculator accepts decimal, American, and fractional input. American cote are converted internally: positive cote use (n/100 + 1) and negative cote use (100/|n| + 1). Fractional cote 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 cote).
The implied probability column shows the raw probability of all legs winning simultaneously: 1 / combined decimal. A 5-leg parlay at average cote of 1.90 per leg gives combined cote of roughly 24.76 and an implied probability 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 cote display readable. At 1win you can build parlays across multiple sports in a single bet slip, mixing football, tennis, basketball, and more.
O greșeală frecventă este să uiți că fiecare picior suplimentar înmulțește riscul, nu doar recompensa. Chiar și adăugarea unui singur 'banker' la cota 1,50 la un parlay înseamnă că și acea selecție trebuie să câștige. Probabilitatea ca toate picioarele să câștige scade dramatic cu fiecare adăugare.

Întrebări frecvente
How many legs can a parlay have?
This calculator supports up to 12 legs. Most sportsbooks, including 1win, allow at least 12-15 selections in a single acumulator. 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 cote. The parlay pays out on the remaining legs.
Are parlay cote better value than single bets?
Parlays offer higher potential payouts but lower expected value because the bookmaker's margin compounds across every leg. Singles generally have better expected value for skilled bettors.
How do I enter American cote?
Select "American" from the format dropdown, then enter positive values for underdogs (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 cote differ from a standard parlay. This calculator models each leg as independent.
