What hedging does

Hedging means betting the opposite side of a wager you already have, so you collect a similar amount no matter which way it lands. People hedge a live bet that has moved in their favor, or the last leg of a parlay, to convert a maybe into a sure thing. You give up some upside in exchange for removing the risk.

The math is simple. Your open bet returns stake × decimalOdds if it wins. To lock that same payout on the other side, you bet hedge = (stake × decimalOdds) / hedgeDecimalOdds. Your guaranteed profit is that locked payout minus everything you staked. When the hedge profit is negative, the two prices are not generous enough and hedging would just lock in a loss, so you are better off letting the original bet ride.

How to use it

Enter your odds and stake from the original bet, then the American price you can get on the opposite outcome. The calculator shows the hedge stake to place, your total outlay, the payout you collect either way, and the locked profit. To find the best hedge price across every book automatically, use the live Hedge Finder. To check whether a hedge is actually +EV before you give up the edge, use the EV Calculator.
