Huajun Software Park provides small partners with software download topics related to Shanghai Four Gold Calculator downloads. This tool can help salaried workers calculate the three insurances, one fund and personal income tax. Users only need to select the city where they work and enter their pre-tax income to calculate the three insurances, one fund, personal income tax and income after being exploited. Since the social security/provident fund payment ratio and base information in most cities are not unified and transparent, currently there are only social security and provident fund payment ratio data for Shanghai, Shenzhen, Beijing, and Tianjin. Data users from other cities can add it by themselves.
