Hedge Bet Calculator

What is a hedge bet?

Hedging is the practice of placing a second bet on the opposite side of an existing position in order to reduce or eliminate risk. The most common scenario: you placed a futures bet at long odds — say, a team to win the Super Bowl at +800 — and that team has now made the championship game. The line on the opponent might be –200. You now have a live decision: let the original ride for the full payout, or place a calculated hedge to lock in some amount of profit regardless of outcome.

Hedging is also used on parlays. If you've hit the first four legs of a five-leg parlay and the final game is about to kick off, you can bet against your parlay's remaining side to guarantee a profit no matter what happens in the last game. The same math applies — the hedge amount is a function of your payout-to-risk ratio and the current odds available.

How to use this calculator

1. Enter your original stake and odds. Use American format. For a futures bet that started at +800, enter +800. For a parlay, enter the total parlay payout odds as American (e.g. if your parlay pays $1,200 profit on a $100 stake, enter +1200).
2. Enter the current hedge odds. This is the price you can get on the opposite side right now. For a championship game futures hedge, this is the opponent's current moneyline. For a parlay, this is the odds on the side opposite your final leg.
3. Choose your mode. Lock Equal Profit calculates the exact hedge stake that produces the same profit whether your original wins or loses — the mathematically optimal hedge if your goal is to guarantee a fixed return. Custom Hedge Amount lets you enter any stake and immediately see both outcome scenarios, so you can stress-test partial hedges or find the right balance between guaranteed profit and upside.
4. Read the scenario table. The table shows net profit (positive) or net loss (negative) in both outcome scenarios — with and without the hedge. The "Difference" column shows what the hedge costs you in the winning scenario, which helps you weigh the trade-off.

When does hedging make sense?

Hedging is a purely personal decision driven by your risk tolerance, not by some universal rule of optimal play. The math is straightforward: a perfect hedge converts expected value into certainty. Whether that trade is worth making depends entirely on your situation.

Hedging makes practical sense when the guaranteed profit represents a meaningful amount relative to your bankroll, when the original bet was a large outright position taken at long odds, or when you're on a parlay and one remaining leg is a significant underdog. It also makes sense when life circumstances change — if you've had a rough month and a guaranteed return offers real relief, that context is legitimate even if it's not "pure" EV thinking.

Where bettors go wrong is hedging reflexively to avoid loss rather than thinking clearly about the trade-off. If your original bet still has strong positive expected value and the guaranteed profit is trivially small relative to your bankroll, hedging may just be anxiety management dressed up as strategy. This calculator gives you the numbers — but the decision is yours.

The math behind the Lock Equal Profit hedge

The formula is simpler than it looks. If your original bet pays a total return of R when it wins (stake plus profit), and the hedge is available at decimal odds of d, then the hedge stake that equalizes both outcomes is: H = R / d. At that hedge stake, both outcomes return the same net profit: R − S − H, where S is your original stake.

This works because when the original wins, you collect R but forfeit H. When the hedge wins, you collect H × d = R but forfeit your original stake S. Set those two expressions equal and solve for H — it reduces directly to R / d. The calculator handles the American-to-decimal conversion automatically, so you can work entirely in the odds format your book displays.
