Calculation of Social Insurance Premium 

Assumed that a company (import and export business in Miyagi prefecture) pays monthly salary of 240,000 yen to an employee (42 years old).

Rate of social insurance premium differs depending on Prefecture, Category of business, age of employee and it is sometimes changed by government.

Health insurance : 240,000 * 11.85% / 2 = 14220 yen is paid by employee.
                                  240,000 * 11.85% / 2 = 14220 yen is paid by employer.

Employee’s pension : 240,000 * 18.3% / 2 = 21960 yen is paid by employee. 
                                       240,000 * 18.3% / 2 = 21960 yen is paid by employer.

Employment insurance : 240,000 * 0.3%  = 720 yen is paid by employee.
                                              240,000 * 0.6%  = 1440 yen is paid by employer.

Accident Compensation Insurance : 240,000 * 0.3%  = 720 yen is paid by employer.

So the employee will receive 240000 – 14220 – 21960 – 720 = 203100 yen.
