Calculation Formula
The calculator uses combinatorial mathematics: nCr = n!/(r!(n-r)!) to determine total parlays. Each parlay's decimal odds = (multiplied odds products). Total payout = sum of (stake * each parlay odds). For American odds: Positive odds = (odds/100) + 1, Negative odds = (100/|odds|) + 1. The formula accounts for all possible winning combinations while maintaining proper risk distribution across all bets.
