Note 3-73

(73) Here, a household with a full-time homemaker is assumed to be as follows: The husband enters employment at the age of 20 and joins an employees' pension plan, marries with a woman two years younger at the age of 28, and retires at the mandatory retirement age of 60. The wife enters employment at the age of 20 and contributes to the employees' pension plan for six years until she gets married with the husband. After the marriage, she becomes a category 3 insured person and does not pay insurance premiums but pays national pension insurance premiums for two years until the age of 60 after the retirement of the husband. Both the husband and the wife die at the age of average life expectancy. As for a single-person household, the assumption is the same as in the case of the husband in the household with a full-time homemaker above, except for marriage.
