The proportion of provident fund refers to the proportion used for provident fund, which generally refers to the proportion of social insurance premiums paid by employees and employers respectively according to a certain proportion. Generally speaking, the proportion of provident fund is set by the government, and each province and its related cities will have different settings.

According to the Notice of the People's Bank of China on Relevant Matters Concerning the Adjustment of the Contribution Ratio of the Basic Old-age Insurance Fund for Urban Employees, the contribution ratio of the basic old-age insurance for urban employees will be adjusted from 8% to 9% from January 1, 219, in which the proportion paid by employers will be adjusted from 16% to 2%, and the proportion paid by employees will be adjusted from 8% to 12%. Therefore, the proportion of provident fund is generally 12%.

the specific proportion of provident fund depends on the regulations of various provinces, such as Beijing's 12:2, Shanghai's 12:22, Guangdong's 12:21, Jiangsu's 12:23, Hubei's 12:24, Hunan's 12:25 and Zhejiang's 12: 25.

In addition, the setting of the proportion of the provident fund has also been adjusted by the government. For example, since July 1, 219, the People's Bank of China issued the Notice on Relevant Matters Concerning Adjusting the Contribution Ratio of the Basic Old-age Insurance Fund for Urban Employees, which stipulates that the contribution ratio of the basic old-age insurance for urban employees will be adjusted from 9% to 1% from July 1, 219, and the proportion paid by the employer will be changed from 2%. The proportion paid by employees is adjusted from the original 12% to 13%, so the proportion of provident fund is generally 13:22, that is, employees pay 13% and employers pay 22%.

Generally speaking, the setting of provident fund ratio is made by the government, and each province and its related cities will have different settings. If there are any changes, they will be announced in time. Therefore, the ratio of provident fund is generally determined by the specific regulations of each province.
