Enter your live bet and the price on the other side. We give you the exact hedge stake to lock the same profit whichever way it lands. Pure math, no signup.
Enter your original stake, your original odds, and the current price on the other side — the calculator returns the exact hedge stake that pays the same amount whichever side wins. That equal-profit stake is the standard answer; you can always hedge less to keep more upside.
Only when the two prices allow it. If your original bet has gained enough value, the locked number is positive; if not, the calculator shows a locked LOSS — hedging then caps your downside rather than minting money. The math is the price of certainty, not an edge.
The calculator shows exactly what certainty costs: the difference between the locked profit and what you'd win by letting the bet ride. Whether that trade is worth it depends on your risk tolerance — the tool gives you the honest number, not a recommendation.
Stake $197.83 on the other side to lock a guaranteed profit of $52.17 no matter which side wins. A negative number means the two prices can only lock a loss — you're capping risk, not minting free money. Pure math, not a pick.

The honest explainer
A hedge is a second bet against your open position, sized so both outcomes return the same amount. It converts an uncertain result into a fixed one. That certainty has a price: you pay the margin on the second bet, always.
The calculator's honest job is showing you that price precisely — the locked amount versus what riding the original position is worth on average.
You hold $100 at +300 and the other side is now available at −110. Equal-return stake: $400 ÷ 1.909 ≈ $210. If your side wins you net $300 − $210 = $90; if it loses, the hedge returns $190.50 profit minus your $100 stake ≈ $90. You've traded a 'maybe +$300 / maybe −$100' position for a guaranteed ~$90.
