How is the hedge stake calculated?

H = (stake1 × decimal1) / decimal2, where stake1/decimal1 describe your original position and decimal2 is the current opposing side's odds. It equalizes the two results before rounding. The calculator checks the cent-sized stakes on either side of H, chooses the better worst-case result, and shows both outcomes.

Does hedging always guarantee a profit?

No. For two opposing outcomes that settle under the same rules, a hedge can limit the worst-case loss or secure a minimum profit. A cent-sized stake can leave a small difference between the two results. The calculator shows both, assuming no fees or voids.

Why can the worst-case result be a loss?

The current opposing odds may not support a profit in both outcomes. A negative worst-case result is not a calculation error. It means at least one outcome loses money at the displayed stake, even if the other outcome does not.

Why can the two results differ after rounding?

Compute it both ways: (stake1 × decimal1 − stake1 − H) for "original wins," and (H × decimal2 − H − stake1) for "hedge wins." They are equal at the theoretical stake. After rounding H to cents, they can differ slightly, so the calculator shows both and labels the lower result as the worst case.

Does this calculator use live sportsbook odds?

No. You type in every number: your original stake and odds, and the current opposing odds. It runs entirely in your browser with no live odds feed and nothing sent to a server.

Worked hedge examples

These are hypothetical two-outcome prices, not live odds. The hedge stake and both outcome results below come from the same calculation as the interactive tool.

Profit locked

Original stake: $100.00
Original odds: +200
Current opposing odds: +150
Equalizing hedge stake: $120.00
Worst-case net result: $80.00
Original wins: $80.00
Hedge wins: $80.00

Loss limited

Original stake: $100.00
Original odds: +200
Current opposing odds: -300
Equalizing hedge stake: $225.00
Worst-case net result: -$25.00
Original wins: -$25.00
Hedge wins: -$25.00

Equalizing assumes the original and opposing sides are exhaustive and settle under the same rules. Pushes, voids, fees and sportsbook payout rounding can change the actual result.

What this is (and isn't)

This is a documented reference implementation of the hedge-stake equalizing formula: choosing a cent-sized stake around the theoretical equalizer, then showing the result for each outcome. The lower result can be a loss rather than a profit. It doesn't show live sportsbook lines, link to a sportsbook, or take a stake for real money. Every number here is one you type in, computed on your device. If you need live odds data behind this math, that's what the API is for.
