Parlay Calculator
A parlay is the US sportsbook term for an accumulator - the math is identical, but legs are usually quoted as moneylines rather than decimal odds.
How it works
Each moneyline leg is first converted to decimal odds, then multiplied together exactly as in an accumulator, giving one combined decimal price and payout.
Worked example: Legs of +150 and -120 convert to 2.50 and 1.83 decimal, combining to 4.58 - a $20 parlay returns $91.60.
FAQ
Do parlays and accumulators use different math?
No - only the odds format usually differs. Once converted to decimal, the combination formula is the same.
Can I mix moneyline and decimal legs?
Yes, convert everything to decimal first with the Odds Converter, then combine.
