The invention discloses a charging method and a charging device. The method comprises the following steps that: a terminal determines a network system currently used by the terminal; and the terminal determines charges for a service used by the terminal according to a charging standard corresponding to the network system. The technical problem of charging difficulty caused by respective and independent charging when a multimode terminal adopts different network systems in the prior art is solved, and the technical effect of improving the charging flexibility of the multimode terminal is achieved.
