题目

HSBC的Net,Gross,Aer（variable）3个利率是什么意思?
开的是FlexibleSaver,3个利息搞不明白.
比如我存了1000磅,一个月有多少利息?
Net：The rate after the diduction of tax applicable to interest,currently 20%.Higher rate taxpayers will have an additional liability.
Gross:The rate before the deduction of tax applicable to interest on savings.
AER(Annual Equivalent Rate)：A notional rate which illustrates what the gross rate would be if interest was paid and compounded each year.

答案

NET是纯利.Gross是税前利.GROSS去掉税就是NET了.AER 是在解释算法,讲毛利的得出.类似于复利,按年把利和本金一起算作基数继续生利.我的理解是您的储蓄账户,是一个可以灵活选择利息计算方式的账户...但是不知道汇丰到...
