What this is (and isn't)
This is a documented reference implementation of the hedge-stake equalizing formula — deriving the stake that makes your result identical regardless of outcome, and showing honestly when that result is 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.
Frequently asked
- 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’s derived by setting the profit if your original bet wins equal to the profit if the hedge wins, then solving for H.
- Does hedging always guarantee a profit?
- No. Hedging guarantees the SAME result regardless of which side wins — but if the opposing odds have moved against you since your original bet, that locked result can be a loss. It’s still usually smaller than what you’d risk by not hedging at all, but it is not automatically a profit.
- Why does the calculator show a "guaranteed loss (minimized)" state instead of just a negative number?
- A negative locked result is a normal, correct output of the hedge formula, not an error — it means hedging is minimizing an unavoidable loss rather than turning your position into a profit. We label it explicitly so it doesn’t read as something having gone wrong.
- How do I verify the locked result is really the same in both outcomes?
- Compute it both ways: (stake1 × decimal1 − stake1 − H) for "original wins," and (H × decimal2 − H − stake1) for "hedge wins." They must be equal, since H × decimal2 equals stake1 × decimal1 by construction. This calculator’s tests assert that equality directly, not just the headline numbers.
- Does this calculator use live sportsbook odds?
- No. Every number — your original stake and odds, and the current opposing odds — is one you type in yourself. It runs entirely in your browser with no live odds feed and nothing sent to a server.
