Online betting calculator for arbitrage betting and trading

Arb Cruncher is a suite of sports betting calculators that calculate the level-profit stakes for arbitrage betting, trading, dutching and synthetic Draw No Bet betting, as well as the returns from parlayed bets (multiples or perms).

Unlike most arbitrage calculators, Arb Cruncher's calculators also support level-stake and commission calculations for both same-exchange and cross-exchange betting.

Enhanced version of Back/Lay

An enhanced version of our Back/Lay calculator is also available at backlaybettingcalculator.com.
