A hedge bet calculator for sports betting: work out how much to bet on the other side of a wager you have already placed — to lock the same result whichever side wins, or just to get your stake back. Use it on a parlay's last leg, a futures bet or a game you bet before kick-off, with Kalshi and Polymarket fees taken off the hedge. Free, no account, and it runs in your browser.
Both lines are net of your original stake, the hedge stake and any fee. The equal hedge breaks exactly even at a hedge price of -250; a better price than that locks a profit, a worse one caps a loss.
Payouts are rounded down to the cent and fees up, so the figure above is the worst case after rounding, not the ideal. It holds only if every leg is placed at the price entered; a price that moves before the second bet is in changes it.
The bonus pays its winnings only, so the hedge covers bonus × (odds − 1), not the full return. If the book restores the token on a push or void, both bets simply settle back to where you started.
This calculator sizes a hedge on a price you already have. TrueEdge compares live prices across US sportsbooks and exchanges, so you can see which book pays the most on the other side — and it lists arbitrage, +EV bets and middles as they appear.
A hedge is a bet on the other side of a wager you already hold, placed so the result depends less on who wins. Enter your stake S, the odds you got d1 and the price now available on the other side d2 (decimal odds; American odds are converted for you), then choose what the hedge should do:
Any stake between the two keeps part of the upside with a smaller floor. The equal hedge only locks a profit when the hedge price beats d1 ÷ (d1 − 1) — for a bet at +150 that is −150; below it, the hedge caps a loss instead. Every result the calculator shows is net of both stakes and of any exchange fee on the hedge, with the hedge rounded to the cent (or to the $1 or $5 you choose).
A hedge is a second bet at a price with the book's margin in it, so it usually costs a little expected value; what it buys is a smaller swing. The price on the other side matters more than the size: shop it across books before placing anything.
$25 on a four-leg parlay at +1450. Three legs have won; the last is Team A's moneyline, and Team B is +140 at another book.
$50 on a team to win the championship at +2000, placed before the season. The team has reached a two-team final, and its opponent is −120.
$100 before the game on an underdog at +150. It leads in the second half, and the other side is now +200 in-play.
Most books will offer to buy a live bet back. A cash-out offer is a total payout that already includes your stake, so compare it with the hedge on the same terms: the hedge's locked profit plus your stake.
Hedging $161.46 locks $201.04 whichever side wins. A cash-out offer matches that only at $226.04 or more — the locked profit plus the $25.00 stake.
Offered $180.00, cashing out nets $155.00; the hedge nets $201.04.
Cashing out is simpler — no second account, no second price — and the book prices that convenience in. If the offer is close, take whichever you can actually place.
It depends on what you want the hedge to do. To finish with the same result whichever side wins, hedge your stake × your decimal odds ÷ the hedge's decimal odds. To get only your stake back if the original loses, hedge your stake ÷ (the hedge's decimal odds − 1). Anything in between keeps some upside with a smaller floor. On a $25.00 parlay at +1450 hedged at +140, that range runs from $17.86 to $161.46.
Only if the certainty is worth something to you. A hedge is a second bet at a price that includes the book's margin, so on average it costs a little expected value; what it buys is a smaller swing. It makes sense when the payout is large compared with your bankroll, and less sense when it is small change. Shop the price on the other side first: the better it is, the more the hedge locks.
The smallest hedge that gives back your original stake if the original bet loses, so the worst case is $0 and everything else stays riding on the original bet. It is your stake ÷ (the hedge's decimal odds − 1). For $50.00 on a future at +2000 with the other side at −120, it is $60.00, and you still net $940.00 if the future comes in.
Compare the two in the same terms. A cash-out offer is a total payout that includes your stake, so it only beats an equal hedge if it is more than the hedge's locked profit plus your stake. On the $25.00 parlay above, the hedge locks $201.04, so a cash-out offer would need to be at least $226.04 to match it; a $180.00 offer nets only $155.00. Cashing out needs no second account and no second price, which is worth something, but the book prices that convenience in.
Yes, and it is usually where the better price is. The hedge does not have to be at the book that holds your original bet. On Kalshi or Polymarket the trading fee comes off the hedge's winnings; choose the venue in the calculator and every figure is shown after that fee.
Back both of the other outcomes, sized so every result pays the same. Use the calculator's Arbitrage tab in 3-way mode with Fix one leg set to your original bet's stake and price, and it sizes the other two.
When the price on the other side is better than your original decimal odds ÷ (those odds − 1). For a bet at +150 that is −150: any hedge price better than that locks a profit either way, and a worse one only caps a loss. A bet whose odds have shortened since you placed it is the usual case.
The worked examples above come from the same arithmetic as the guides below, which go further into when a hedge is worth its cost.
