The ultimate goal of this study is to develop personal finance materials for college students based on the Lifetime Wage Model. In this report, we created a Lifetime Wage Model, calculated the Non-Living Expenditure and the individual-type defined contribution pension plan (iDeCo) tax shield based on it, and confirmed the model’s validity. Assuming that university graduates begin employment in April of the year they turn 22 years old, that they retire in March of the year they turn 60 years old, and that their length of service is 38 years, the Lifetime Wage was about 265.67 million yen for male university graduates, and about 209.91 million yen for female university graduates. The total Non-Living Expenditure for this was 68.33 million yen for men, and 48.69 million yen for women. Additionally, if an individual has an iDeCo of 23,000 yen per month from immediately after employment until they are under 60 years old, the cumulative lifetime principal for both men and women is about 10.42 million yen, and the tax shield is about 2.74 million yen for men and about 2.25 million yen for women.
