How the Premiums are Determined

  • Salary-based premiums are determined based on one’s monthly salary and Bonus-based premiums are determined based on bonuses.
  • Salary-based premiums are calculated by multiplying the premium rate by one’s Monthly Standard Salary.
  • Bonus-based premiums are calculated by multiplying the premium rate by the one’s Standard Bonus.
  • A member (excluding Voluntarily Continued Insurance Members) and the school where they belong each pay half of the payment of both Salary-based and Bonus-based premiums. However, During Maternity leave periods and a Childcare leave period taken until the child reaches age 3, the Salary-based and Bonus-based premiums are exempted if an application is made.
  • The premiums paid by a Voluntarily Continued Insurance Members are calculated by multiplying the Short-Term Benefit premium rate by one’s Monthly Standard Salary at the time of retirement, and the premiums must be paid solely by the member in full.

How to Calculate the Amount Borne by a Member

The amount to be borne by a member is a half of the total amount resulting from multiplying each of the member’s “Monthly Standard Salary” and “Standard Bonus” by the respective premium rate. If the amount contains any fraction, it is processed as follows:

When the school deducts the amount to be borne by the member from the member’s salary, if the halved amount has a fraction of 50 sen or less, the fraction is rounded down to 0 and if the fraction is 50 sen or more, it is rounded up to the nearest 1 yen.

<Calculation example>

Premium category Monthly Standard Salary Premium rate Premium amount Half amount Amount to be borne by the member
