Hmm...I may be wrong, I did a quickie on excel and it came out right for all my accounts.
This is the formula I used. It came out exactly the interest accrued for today :
=ROUND((((50000)*(1+3.5%)^(1/365))-(50000))+(((current value-50000)*(1+3%)^(1/365))-(current value-50000)),2)
*side note, don't forget to calculate the "compounding" factor. Put it in another way, that interest amount will only compound to a total of 3.5% after 365 days. The interest accrued is not linear, starts less and increasing ever so slightly.. So daily percentage is not equal.. Its increasing by the day.
In other words, it's not 3.5% p.a. unless left there for 365 days.
P. A. is 3.5%...but how it gets there is stated individually. Example, FD 12 months, they give it to you by then, but for KDI Save, they did say 3% compounded daily. So they are giving it to you, just not in linear form where its divided into 365 interest payments.
If its still confusing, try putting it as simple as possible into excel, drag it down to 365 days, look at each row, and see the effect of compounding.
(unsure, stand to be corrected)..
I certainly hope I'm right, otherwise I'm cheated as well.. Haha..oh well..
Anyway, to each their own.. have fun..
They have calculation example on their faq digitalinvesting.com.my/faq/, go to - general kdi save,
it's under ""what is ear"" , I think that's more accurate & reliable.
