Arbitrage Calculator
Find arbitrage opportunities across sportsbooks and calculate optimal stake distribution for guaranteed profit regardless of outcome.
Arbitrage betting (arbing) exploits price differences between sportsbooks to lock in a guaranteed profit no matter the outcome. When Pinnacle offers Home at 2.15 and Dafabet offers Away at 2.05, the combined implied probability may drop below 100% — that gap is your risk-free profit. This calculator checks whether two or three outcomes across different bookmakers create an arb opportunity, and tells you exactly how much to stake on each outcome to equalize your return. In APAC markets, arb opportunities frequently arise between sharp books (Pinnacle, SBOBET) and recreational books (Dafabet, 1xBet) because recreational books are slower to adjust lines. The window is usually narrow — minutes, not hours — so speed matters. Be warned: most sportsbooks actively detect and limit arbers. Pinnacle is the notable exception, welcoming all bettors regardless of strategy.
Enter decimal odds from different sportsbooks for each outcome to find arbitrage opportunities.
How It Works
Select 2-way or 3-way market, enter the best decimal odds for each outcome from different sportsbooks, and set your total investment. The calculator shows the arb percentage, guaranteed profit, and exact stake to place on each outcome. A positive arb percentage means guaranteed profit.
Frequently Asked Questions
How much can you realistically make from arbitrage betting?
Individual arb opportunities typically yield 0.5-3% profit per event. With a $10,000 bankroll cycling through multiple arbs daily, experienced arbers report 5-15% monthly returns. The main constraints are bet limits, account restrictions, and the speed required to capture arbs before odds move.
Will sportsbooks ban me for arbitrage betting?
Most recreational sportsbooks (Dafabet, Bet365, 1xBet) will limit or close accounts that consistently arb. Pinnacle explicitly welcomes arbers and never limits winning accounts. SBOBET is moderately tolerant. Strategy: use recreational books for the side with worse odds, and Pinnacle for the sharp side.
What is the difference between arbitrage and value betting?
Arbitrage guarantees profit by covering all outcomes across different books — zero risk, small returns. Value betting backs only the +EV side without hedging — higher risk per bet but much higher long-term returns because you keep the full edge rather than splitting it across outcomes.
