Commission baccarat involves a 5% fee on winning Banker bets, offering a lower house edge on the Banker bet (about 1.06%). In no-commission baccarat, no fee is charged on winning Banker bets, but a Banker hand totaling 7 is a push. The absence of commission is balanced by a slightly higher Banker bet house edge (around 1.24%). The choice between them depends on your preference for lower house edge versus avoiding commissions.
