Arbitrage Calculator
Find 2-way arbitrage opportunities and calculate the exact stake split to lock in a guaranteed profit.
An arbitrage bet ("arb") happens when you can bet both sides at different sportsbooks and lock in a profit. This calculator tells you whether an arbitrage exists, your edge, and the exact stake split to guarantee the same payout either way.
Enter odds for each outcome (e.g., both moneylines in a 2-way market). For best results, shop lines and use the best price you can find for each side.
