Arb Cruncher - free online sports betting calculator

Arb Cruncher is a free online sports betting calculator that calculates level-profit stakes for arbitrage betting, trading and dutching on betting exchanges. It also performs many other useful calculations for Asian handicap betting, binary betting, price inversion, implied probability, the Kelly criterion and much more.

Arb Cruncher is a standalone calculator and does not place bets for you. For live transactional trading software, we highly recommend Bet Angel (with its excellent In-Play Trader feature) and BetTrader Evolution (with its dynamic ladder interface).

The live online calculator is shown below and is also available in a useful popup window that you can open at any time from the navigation menu in the left sidebar. Convenient one-click access to this popup calculator is also provided by the Arb Cruncher toolbar, which may be downloaded to IE browsers here.

Please note that Arb Cruncher does not perform calculations for casino betting.
