How to use the Parlay Calculator
A parlay multiplies the decimal odds of every leg together. The more legs you add, the higher the payout — and the lower the win probability. A 4-leg parlay of -110 legs (each 52.4%) wins about 7.5% of the time. The payout looks great, but the math is brutal.
This calculator combines your legs in real time. Enter each leg's odds in whichever format you read fastest — American, decimal, or fractional — and we'll show the combined price, your potential payout, and the implied probability the parlay must hit to break even.
For same-game parlays (SGPs) the math is different — sportsbooks adjust the price down for correlation between legs from the same game. If you're pricing an SGP, use the actual quoted SGP price from your book rather than multiplying the legs yourself.
