This online tool calculates various strategies when a hedging opportunity exists on a betting exchange such as Betfair, where you can back and lay selections.


If you’re looking for something more versatile, our new Betting Exchange Arbitrage & Hedging Calculator calculates various strategies when an arbitrage or hedging opportunity exists using a betting exchange such as Betfair, Smarkets or WBX. The calculator also works for strategies that combine bookmaker (back) wagers with exchange lay bets.

Hedging opportunities occur in two scenarios:

1. You have made a back wager and the lay odds have since fallen below your back odds
2. You have made a lay wager and the back odds have since risen above your lay odds

This calculator calculates three strategies. One aims to achieve the same profit regardless of the event outcome, while the other two aim to deliver a profit in one scenario, with no profit or loss otherwise. If you haven’t done so already, be sure to view our guide on hedging with Betfair.

A hedging opportunity arises when you have made a wager and the exchange odds have since shifted in your favour. If you are placing your wagers with different exchanges or if your back wager is with a bookmaker then you should use our more flexible Betting Exchange Arbitrage & Hedging Calculator.
