牛，这才是财务的真正Excel水平！

1.个人所得税计算公式

=ROUND(MAX((I3-3500)*{0.03,0.1,0.2,0.25,0.3,0.35,0.45}-{0,105,555,1005,2755,5505,13505},0),2)

2.根据实发工资，倒推税前工资

=IF(K3<=3500,K3,ROUND(MAX((K3-3500-5*{0,21,111,201,551,1101,2701})/(1-5%*{0.6,2,4,5,6,7,9}))+3500,2))

3.根据实发工资，获取大写金额

=SUBSTITUTE(SUBSTITUTE(TEXT(TRUNC(FIXED(K3)),"[>0][dbnum2]G/通用格式元;[<0]负[dbnum2]G/通用格式元;;")&TEXT(RIGHT(FIXED(K3),2),"[dbnum2]0角0分;;"&IF(ABS(K3)>1%,"整",)),"零角",IF(ABS(K3)<1,,"零")),"零分","整")

4.根据期限和调整日期两个条件，查询利率。

数组公式，按Ctrl+Shift+Enter三键结束。

=INDEX(C:C,MAX(IF(($A$3:$A$10=E3)*($B$3:$B$10<=F3),ROW($3:$10))))

5.获取每个日期的时间段

=LOOKUP(DATEDIF(B2,TODAY(),"m"),{0,1,2,3,6,12},{"不足1个月","1-2个月","2-3个月","3-6个月","6-12个月","1年以上"})
