From this we can calculate that if a company hires a 45-year-old worker who keeps working until retirement at 60, it will have to pay two base units into the retirement fund for each year of that person's employment; but if it hires a 25-year-old who stays until retirement, the maximum 45 base units will be spread over 35 years, making less than 1.3 units per year--a substantial difference.
換算起來，老闆如果錄取一位四十五歲的受雇者，從進用到六十歲退休，一年要付出兩個基數的退休準備金；而一位二十五歲的受雇者，從進用到退休，最高四十五個基數分攤在三十五年內，一年不到一．三個月，划算多了。
