Arbitrage and
hedge calculator
Enter the price for each outcome. The calculator shows whether the prices leave a gap, how to split your stake so every result pays the same, and how to hedge a pick you already have.

How it works
Every price implies a chance. Add up every outcome of a game: over 100% is normal (the site's cut), under 100% is a gap.
Each stake is your total × that outcome's share of the sum, so every result pays the same. Fix one stake starts from a stake you already know. Hedge a pick sizes the other side of a pick you already made.
Before you try it
- Place the side most likely to moveGaps close fast
- Re-check the second priceThen place it
- Compare redeemable valueSocial sportsbook coins aren’t always 1:1
Bonus coins usually need a playthrough and often can't be hedged under a site's rules. See the bonus value calculator.
Questions
What is an arbitrage (arb)?
Two or more sites price the same game differently enough that backing every outcome returns more than the total you put in. It happens when the implied chances of all outcomes add up to less than 100%.
Is an arb risk-free?
No. Prices move while you place the second side, sites can cancel a pick made at a price they call an error, and many sites limit or close accounts that only take arbs. Sweepstakes and social sportsbooks also have their own rules on bonus coins and multiple accounts. Read each site's terms first.
What does hedging do?
Hedging means taking the other side of a pick you already made so the result matters less. The calculator shows the stake that leaves you with the same result either way, and what each outcome pays.
Can I use this with Fliff or Novig?
The math works with any prices. Social sportsbooks pay in their own prize coins, so only compare like with like, and check each site’s rules on hedging bonus coins before you rely on it.

These calculators do math, not predictions. No price is a sure thing: sites can change lines, cancel picks made at a wrong price, limit accounts, or close markets before you place the other side. Never stake money you need, and never treat picks or trading as a way to make money. 21+. Gambling problem? Call or text 1-800-GAMBLER. Play responsibly.
