About this tool
The Hedge / Cash-Out Calculator works out how much to stake on the opposite outcome so that you win the same amount no matter which side comes in. Starting from an original bet of stake S at decimal odds d1, its potential return is R1 = S × d1. Placing a hedge at the opposing odds d2 with stake H = R1 / d2 makes both outcomes return exactly R1, so your profit is locked at R1 − (S + H) regardless of the result.
All of the arithmetic runs locally in your browser, and nothing you enter leaves your device. Choose whether your prices are American, decimal, or fractional; the tool converts both legs to decimal internally. It then reports the hedge stake, your total outlay (S + H), the guaranteed profit or loss, the locked-in ROI on that outlay, and the equal return both sides now pay. This is the same math a sportsbook uses to price a cash-out offer, so comparing the locked profit here to the cash-out button tells you whether the book is giving you fair value.
This is a pure math reference — it does not touch real money or place bets. A guaranteed profit only exists when the combined implied probability of the two legs is below 100%; otherwise the locked figure will be negative, meaning hedging simply caps your loss. Odds move quickly, so treat the result as a snapshot at the prices you entered.
