Sports Betting Calculator

This handles the betting arithmetic that goes beyond a single price. Enter two to six legs in American odds and it multiplies them into the combined price, the payout on your stake and the implied chance that every leg lands. A hedge mode takes the bet you already hold and the price now available on the other side and returns the stake that leaves the same return either way, along with the profit or loss that locks in. A third mode reads both sides of a market and reports the overround, the operator hold and the no-vig probabilities. It converts numbers only and makes no claim that any price, parlay or hedge is worth taking.
