About Hedge Calculator
Free, independent calculators that show the stake math behind a hedge, with every assumption stated next to the result.
What Hedge Calculator offers
Hedge Calculator does one job: it works out how much to stake on the other side of a bet, and what each outcome is then worth after every cash stake is counted. There are eight calculators, each built for a different situation:
- Hedge calculator for a standard two-outcome cash bet.
- Parlay hedge calculator for the final open leg of a parlay.
- Multi-way hedge calculator for markets with three, four or five outcomes.
- Bonus bet hedge calculator for stake-not-returned bonus bets and free bets.
- Risk-free bet hedge calculator for second-chance bets refunded as a bonus.
- Profit boost hedge calculator for percentage boosts on winnings.
- Back-to-lay hedge calculator for a sportsbook back bet laid at an exchange.
- Arbitrage hedge calculator for splitting a budget across two outcomes.
The guide to calculating a hedge bet explains the formula behind every one of them.
Who it is for
The site is written for adults of legal gambling age who already hold a bet or a promotion and want to check the numbers before deciding what to do. Amounts are in dollars, odds can be entered in American or decimal format, and the explanations use US sportsbook terms such as bonus bets and profit boosts.
It is also useful if you simply want to understand how hedging works. It is not a tipping service: it will not tell you what to bet, find bets for you or predict results.
How the content is produced
Every calculator and every explanation on the site starts from the same written formula, so the numbers in the text, the worked examples and the calculator itself always agree.
A stated model for each calculator
Each tool has a defined model: which outcomes it covers, what counts as cash staked and what it leaves out, such as fees, voids or pushes. Those limits are printed next to the calculator, not hidden in small print.
Exact arithmetic
The math uses exact fractions instead of floating-point numbers. Stakes are rounded to the cent, and every outcome is then recalculated from the rounded stake. When rounding leaves a one-cent difference between outcomes, the result shows it rather than hiding it.
Automated checks before every release
An automated test suite recalculates the worked examples and edge cases, including losses, break-even results, rounding and invalid input. A new version of the site is not published if any of those checks fails.
Plain explanations
Explanations are written to describe what a number means, not to persuade you to bet. When a hedge locks in a loss, the page says so.
Editorial principles
- No tips or predictions. The site explains calculations and never recommends a bet.
- No advertising or paid placements. There are no ads, sponsored posts or affiliate links. Sportsbook and exchange names such as Betfair or Smarkets only identify a use case.
- Losses are shown as losses. A negative outcome is labeled as a modeled loss, in words as well as in color.
- Assumptions come first. Every calculator lists what it assumes and what it does not cover.
- Responsible gambling. A calculated result is never a reason to bet more. See the responsible gambling page.

When a calculator or explanation changes, its formulas and worked examples are checked again with the same automated tests before the update goes live. The guide shows the date it was last updated.
