Free Bet to Cash Calculator

A free bet stakes but never returns, so its value is whatever the other side pays. We hold every book's price and size the hedge that converts yours at the best rate. Math, not picks. Lines move, re-check before you place.

Hold profit boosts at other books? Enter each one: the book, the boost %, and the max bet it covers. The hedge splits across them, best effective odds first, then regular prices finish the fill. When rows are filled here, the single hedge-boost field above is ignored. Saved boosts load from your Profit Boost Wallet automatically, and each one is checked against its own fine print (expiry, minimum odds, singles-only, sport, market) before it can change a number. Two switches turn them off: Show Profit Boosts From Wallet above is the master switch for this page, and a boost you switched off in the wallet stays off here whatever that switch says. Rows you type yourself are never touched by either.

What a Hedge Finder Does

A hedge finder locates the best available price on the opposite side of a bet you already placed, so you can lock in a profit or cap a loss before the result lands. A hedging calculator tells you how much to stake once you have found both prices yourself. A hedge finder goes further: it already holds every book's number, so it finds the price and does the math in one pass.

How This Hedge Finder Works

The Odds Gap holds live prices from every tracked book, sportsbooks and prediction-market exchanges alike, including Kalshi, Polymarket US, ProphetX, and Novig. Pick your game and side, enter your stake, and the scanner ranks every hedge from best to worst with the exact stake to place and the profit you lock either way. It runs seven modes: a standard hedge on any open bet, free bet conversion, profit and odds boosts, no-sweat bets, wager requirements, a futures hedge that backs the rest of a tournament field at each outcome's best price, and a full arbitrage scan across the whole board. Every result links straight to the book carrying the price, and nothing here requires a signup.

When to Hedge

Hedge when a guaranteed number is worth more to you than the gamble: the last leg of a long parlay, a futures ticket that has shortened hard, or any spot where the swing is bigger than you want to carry. If a book has offered you a cash-out, enter it and the tool tells you whether that offer beats the real market or shorts you.

The Honest Math

Hedging locks a result, but it costs expected value. The hedge leg pays the second book's vig, so your average outcome is slightly worse than letting the bet ride. That is the whole trade: certainty now for a small haircut on EV. We show you the locked number and the breakdown either way, and you decide. Math, not picks. Lines move fast, so re-check the price before you place.
