Arbitrage calculator

Enter the two best prices for opposite outcomes (from different bookmakers) and your total stake. If the implied probabilities add to under 100%, there's an arb — we'll split the stakes for you.

Outcome A odds (decimal) Outcome B odds (decimal) Total stake (£)

⚠️ The catch: real arbs are small, disappear fast, and bookmakers limit or ban accounts that do this. See the honest guide.

We only show locally-licensed operators to visitors in your region.

This is a regulated market, so we only advertise operators that hold a local licence here. The bookmakers we review are licensed elsewhere, and we won't promote them to you — so you'll see no betting offers on this page. Our reviews, licence checks and guides stay available — we've removed the advertising, not the information. 18+ · Support and safer-gambling tools.
