Parlay / akkumulatur calculator
How this calculator works
A parlay (also called an akkumulatur or acca) combines multiple individual agħżelions into a single bet. All legs must win for the bet to pay out. The combined odds equal the product of each individual leg's decimal odds.
The formula is straightforward: Combined decimal odds = leg1 x leg2 x ... x legN. For example, three legs at 2.00 each produce combined odds of 8.00. A 10-unit stake returns 80 units total, or 70 units net profittt.
The calculator accepts decimal, American, and fractional input. American odds are converted internally: positive odds use (n/100 + 1) and negative odds use (100/|n| + 1). Fractional odds convert via (numerator/denominator) + 1.
Each leg also carries a win/lose agħżelor. 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 odds).
The implied probabbiltà column shows the raw probabbiltà of all legs winning simultaneously: 1 / combined decimal. A 5-leg parlay at average odds of 1.90 per leg gives combined odds of roughly 24.76 and an implied probabbiltà around 4%. This figure does not kont for bookmaker margin, so the true probabbiltà will be even lower.
Massimu 12 legs are supported. This logħbiet common sportsbook limits and keeps the combined odds display readable. At 1win you can build parlays across multiple sports in a single bet slip, mixing futbol, tennis, basketball, and more.
A common mistake is forgetting that each additional leg multiplies risk, not just reward. Even adding one 1.50-priced "banker" to a parlay means that agħżelion must also win. The probabbiltà of all legs winning falls dramatically with each addition.

Mistoqsijiet Frekwenti
How many legs can a parlay have?
This calculator supports up to 12 legs. Most sportsbooks, including 1win, allow at least 12-15 agħżelions in a single akkumulatur. The minimu is 2 legs.
What happens if one leg is void?
If a agħżelion is voided (cancelled by the bookmaker), that leg is treated as a 1.00 decimal and removed from the combined odds. The parlay pays out on the remaining legs.
Are parlay odds 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 odds?
Agħżel "American" from the format dropdown, then daħħal 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-loġħba parlay combines multiple outcomes from a single logħba. The legs are correlated, so true odds differ from a standard parlay. This calculator models each leg as independent.
