先前我們提到一種退休金動態提領策略，「設定提領百分比上下限」，這是一種將「固定美元」提領策略與「固定百分比」提領策略，兩種的想法結合，既考慮實質購買力，也顧慮到退休金可能在預期的期限內提領完畢的問題。
那我們是不是有可能從退休金的資產配置裡，再多領一些錢出來用，答案是可以的，就是這次要介紹的「可變百分比」提領策略。
所謂的「可變百分比」提領策略，除了將「固定美元」提領策略與「固定百分比」提領策略，兩種的想法結合，還將「n分之一」提領策略的想法也納入，所以「可變百分比」既考慮實質購買力，也顧慮到退休金可能在預期的期限內提領完畢的問題，還計畫在預定的期限內將所有的錢剛剛好領用完畢，這也就是「可變百分比」提領策略能夠有機會再多領一些錢出來用的作法。
這個提領策略的作法相當簡單，有兩種執行的方法，第一種方法是查表，我們舉個例子來說明。
首先我們需要以下的一些假設條件：
1.你預期提領的期限為年齡100歲，也就是說，當你年紀到100歲時，你計劃剛剛好把退休金提領完畢。
2.你計畫65歲退休，所以你未來必須從退休金中提領35次來支出生活費。
3.你的資產配置組合是全球股市與全球長期政府債券，並且配置比例為60％股票、40％的債券。
我們來看看下表紅字部份，紅字的百分比由5％一直提高至100％，65歲提領5.0％、66歲提領5.1％以此類推，這就是每年你須從退休金中提領的比率，是不是很簡單。
