Online arbitrage betting calculator for arbing, trading & dutching


Arb Cruncher is a multipurpose online sports betting calculator containing 6 calculators for arbitrage betting (book and back/lay), trading, dutching and synthetic Draw No Bet betting, as well as the returns from all multiples up to 10-folds.

It supports all price types (fractional, decimal and US) and also takes into account betting exchange commission (from both same-exchange and cross-exchange betting). It should, of course, be pointed out that the key to all successful arbing and trading is getting access to tbe best prices, a valuable service that's provided by BetInAsia and other bet brokers.
