The present invention discloses a charging method and system for a prepaid service. The charging method comprises the following steps that: a VPN charging management module presets different VPN package charging levels in the prepaid service, receives a calling request from a user terminal, and determines whether there is at least one VPN valid user in a calling terminal and a called terminal and determines whether this calling belongs to the preset different VPN package charging levels; and a VPN charging module charges the calling terminal or the called terminal which is a VPN valid user for this calling according to the VPN package charging level to which the calling terminal or the called terminal belongs, and ends this calling if the amount of the user terminal account is insufficient. The present invention realizes the flexible VPN charging in the prepaid service, not only enables a user to enjoy more flexible charging and save charges conveniently, but also it is favourable for the service promotion of operators, without changing the existing service framework structure and development interface, and saves the development costs of operators by synchronizing to multiple systems by a synchronization module.
