Frequently Asked Questions
How do you calculate arbitrage betting profit?+
Convert each outcome's odds into implied probability and add them together. If the total is below 100%, the difference represents the arbitrage edge. The calculator then splits your stake across outcomes so each result targets a similar total return. Read the arbitrage betting guide.
What odds do I need for an arbitrage bet?+
You need the best available odds across every outcome to combine to less than 100% implied probability. Arbitrage usually happens when different bookmakers have out-of-sync prices on opposite sides of the same market.
Does the arbitrage calculator include commission?+
The calculator works from the odds you enter. If an exchange charges commission, use commission-adjusted effective odds so the profit estimate reflects the true net return.
