公教 定期儲蓄存款 半年給息 利率1.595%
附件為細算公式 至少問了六位行員
如果不說 你一定不知道Trick在那裡
那一家的我不想說了
最後得知 它是單利 同時 以int(integer整數去除小數點) 來算
你可以心算出第一年前兩個月是 0
無言...........................
公教人員 你們辛苦了
台北富邦數位客服:
定存利息的計算方法，採按日計息
一、算式：本金X年利率/365天*存款天數，
故每月給息者，金額可能因月份天數不同有些微差異
注意它是 [按日計息]
由於沒有註明是四捨五入 所以我一概去除小數點
10000*1.595%/365*1 = 0.43698630137 第1天 利息是 0
10000*1.595%/365*1 = 0.43698630137 第2天 利息是 0
第一個月 利息 0
////////////////////////////細算公式///////////////
Result0: 858 第一年利
Result1: 2801 第二年利
Result2: 4760 第三年利
