Arbitrage Calculator

Understanding Arbitrage Betting

Arbitrage betting (also known as "arbing" or "surebets") exploits differences in odds across sportsbooks to guarantee a profit regardless of the outcome.

When the combined implied probabilities of all outcomes fall below 100%, an arbitrage opportunity exists. The calculator identifies this and shows exactly how much to stake on each outcome for risk-free profit.

• Guaranteed Profit – You win no matter which outcome occurs.
• Low Risk – The only risks are sportsbook limits or odds changing before you place all bets.
• 2-way & 3-way Markets – Works for moneyline/point spread (2-way) and 3-way markets (win/draw/win).

How to Use the Arbitrage Calculator

• Enter the best available American odds for each possible outcome from different sportsbooks.
• Input your desired total stake amount.
• Click "Calculate Arbitrage" to see if an opportunity exists and the exact stakes needed.
• If arbitrage is found, place the calculated bets quickly before odds change.

The tool automatically converts odds to implied probability and distributes stakes proportionally for maximum guaranteed profit.
