Matched betting calculator: how to hedge a sportsbook bet
The matched betting calculator tells you how much to stake on the opposite outcome so a bet you place at one sportsbook is hedged whatever happens: enter the stake and American odds of your bet, the odds of the other side (at another sportsbook or on ProphetX) and get the hedge stake and the profit or loss for every result. It handles cash bets, bonus bets, second chance bets, playthrough and profit boosts, and it is the same calculator members use inside the Bet Finder.

Frequently asked questions
What is a matched betting calculator?
A tool that splits your money across the outcomes of a game so the result is the same whichever side wins. It is how you turn a sportsbook promotion into a predictable return instead of a gamble.
How is the hedge stake calculated?
Hedge stake = (stake × decimal odds of your bet) ÷ decimal odds of the other side. The calculator converts American odds for you, adapts the formula to the mode (bonus bet, second chance, playthrough, boost) and rounds to sensible amounts.
Why is a real-money hedge slightly negative?
Because both sportsbooks keep a margin: covering a qualifying bet usually costs 1-5% of the stake. The value comes from the bonus bet or boost the qualifying bet unlocks.
Does it work with bonus bets?
Yes. In Bonus Bet mode the stake is not returned on a win, so the calculator sizes the hedge to extract as much of the bonus as possible, typically 70-80% of its face value: that share is your conversion rate.
Is the calculator free?
Yes, no signup needed. A free account lets you save bets to the Bet Tracker; Premium members find the same calculator inside the Bet Finder, prefilled with the odds of each row.
