Arbitrage Calculator
🎯 What is Arbitrage (Surebet)?
The Arbitrage Calculator is a professional tool for identifying and executing surebets - opportunities where you guarantee profit regardless of the sports event outcome. Arbitrage occurs when the sum of the reciprocals of the odds is less than 1.
Arbitrage Condition: 1/Odds₁ + 1/Odds₂ + ... + 1/Oddsₙ < 1
⚙️ How Does Arbitrage Calculation Work?
Arbitrage calculation distributes the total stake proportionally to the reciprocals of the odds. The formula is:
Bet for each outcome = (Total Stake / Sum of Reciprocals) × (1 / Outcome Odds)
When the sum of reciprocals is less than 1, the return will always be greater than the amount invested, guaranteeing profit.
