Arbitrage betting exploits differences in odds between bookmakers to guarantee profit regardless of the outcome. When the sum of implied probabilities across all outcomes is below 100%, a guaranteed profit exists. Our calculator finds this instantly.

Formula: Arbitrage % = (1 − (1/Odds1 + 1/Odds2)) × 100. Any positive result means guaranteed profit.

Warning: Bookmakers may limit accounts of known arbitrage bettors. Always bet natural-looking amounts and use multiple accounts.
1. Enter your total bankroll for this bet in the Stake field.

4. For soccer or any 3-way market, tap "+ Add Third Outcome" and enter the Draw odds.
5. The calculator instantly shows your guaranteed profit and exact stake for each book.

Yes. Arbitrage betting is legal in virtually every jurisdiction where sports betting is legal. You are simply placing bets at different bookmakers — nothing illegal about that. The risk is account restriction by bookmakers who identify arbers, not legal consequence.

To minimize restriction risk: vary your stake sizes, don't always take the maximum, and spread action across many bookmakers.
