An arbitrage calculator checks whether the odds you enter across all outcomes add up to less than 100% implied probability. If they do, it splits your stake so each outcome targets the same payout and shows the modeled profit before execution risk.
Combined Implied Probability = Σ(1 / Decimal Odds); Stake per Outcome = Target Payout / Decimal OddsConvert each price to decimal odds, add the implied probabilities, then divide your total stake by that combined implied probability to find the equal target payout. Each outcome stake is target payout divided by that outcome decimal odds.
Convert every outcome to decimal odds, add the implied probabilities, and divide total stake by that sum to get the equal target payout. Then divide that payout by each outcome odds to get the stake for that outcome.
A combined implied probability below 100% means the entered prices model negative hold before execution risk. Above 100% means covering every outcome costs money at those prices.
No. The calculator shows theoretical math from the numbers you enter. Real execution can fail because prices move, limits apply, one side is rejected, bets are voided, or book rules differ.
