Hedge Calculator
Lock in a result by betting the other side. Enter your original bet and the current price on the opposite outcome to get the hedge stake and your guaranteed profit either way.
When to hedge
Hedging means betting the opposite side of a wager you already have so the outcome no longer matters — usually to lock in profit on a longshot that's close to hitting (a futures ticket, the last leg of a parlay) or to cut a loss.
To equalize your profit whichever side wins:
hedge stake = (original stake × original decimal odds) ÷ hedge decimal odds
Worked example
You have $100 on a +400 future (returns $500). The other side is now -120 (1.833). Hedge stake = 500 / 1.833 = $272.73. Either way you end with about $127 back on $372.73 risked — a locked $127 profit.
Hedging trades upside for certainty. It's +EV to hedge only when the opposing price is soft; otherwise you're paying the vig to buy peace of mind.
Stop doing this by hand
These calculators do one bet at a time. PropPrizm's EV+ board runs the de-vig and EV math across every book, on every prop, live — and surfaces only the ones where a book is soft versus the market consensus.

Should I always hedge a big bet?
Not always. Hedging locks in profit but caps your upside, and you pay the vig on the hedge. Hedge when the certainty is worth more to you than the expected value you give up, or when the opposing price is genuinely soft.
How much should I bet to hedge?
Enough that both outcomes return the same amount: hedge stake = (original stake × original decimal odds) ÷ hedge decimal odds. The calculator computes this and shows the guaranteed result.
Can I always hedge into a guaranteed profit?
Only if your original bet has appreciated enough relative to the current opposing price. If it hasn’t, hedging minimizes your loss rather than guaranteeing a profit.
