How a parlay payout is calculated
Each leg's American odds convert to decimal odds, and the decimals are multiplied together to get the parlay's combined odds. Your payout is your stake times that combined number. The catch: multiplying odds also multiplies the risk — a 3-leg parlay of −110 favorites only hits about 14% of the time. The "Win %" field shows you exactly that, so you know what you're really getting for the bigger payout.
