Calculation Principle and Formula of Contribution
- Calculation Principle:
"Contribution Days" means calculation is made commencing from the day a worker was employed and started contributing until the worker had left his/her job and stopped contributing, calculated at an average of 30 days per month.
- Calculation Formula:
Employer's contribution ＝ Monthly contribution wages × employer's contribution rate × contribution days ÷ 30
Voluntary contribution＝Monthly contribution wages × voluntary contribution rate × contribution days ÷ 30
- Example:
A worker worked from March 1 to 15, 2023 for 15 consecutive days at a daily wage of NT$1,600. His/her employer should report contribution from March 1 to 15, 2023. Monthly contributions shall be converted from his/her daily wage to monthly salary at NT$48,000. According to the Monthly Contribution Classification of Labor Pension, his/her wage shall be reported under grade 36 at NT$48,200. Therefore, employer's contribution for the employer for March 2023 is:
NT$48,200 × 6% (assumed employer’s contribution rate) × 15 days ÷ 30 days ＝ NT$1,446
