Parlay / accumulator calculator
Hur denna kalkylator fungerar
A parlay (also called an accumulator or acca) combines multiple individual selections 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 totalt, or 70 units net profit.
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 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 odds).
The implied probability column shows the raw probability 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 probability around 4%. This figure does not konto for bookmaker margin, so the true probability will be even lower.
Maximum 12 legs are supported. This matches common sportbook limits and keeps the combined odds display readable. At 1win you can build parlays across multiple sport in a single bet slip, mixing football, tennis, basketball, and more.
Ett vanligt misstag är att glömma att varje ytterligare arm multiplicerar risken, inte bara belöningen. Att lägga till en 1.50-prissatt "banker" i ett kombispel innebär att det valet också måste vinna. Sannolikheten att alla armar vinner sjunker dramatiskt med varje tillägg.

FAQ
How many legs can a parlay have?
This calculator supports up to 12 legs. Most sportbooks, including 1win, allow at least 12-15 selections in a single accumulator. 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 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?
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 odds differ from a standard parlay. This calculator models each leg as independent.
