Thanks for the explanation.
The actual interest credited in my Affin SA is RM 543.32. Well, I am not a cheapskate and claim 1 cent from Affin Bank, as the bank may claim it as a rounding error.
How did you know beforehand that the bank's actual credited interest is actually 1 cent less than the interest I calculated?
Not really. I am just an Average Joe. And, RM 1 is not so useful these days.
For me, I just want to learn from your all FD experts, on the proper way to calculate the FD interest, so that I get the FD interest I deserve.
Different banks have different programs for dealing with the last sen of interest. In the case of Affin, it appears that
their program will simply take the final nearest rounded sen and minus 1 sen. In your case, you were rounded up, and they cut 1 sen. In my case, I was rounded down, but they still cut 1 sen. Of course this appears dubious, because Affin should have just truncated i.e. always rounded down to the nearest 1 sen. From this, it appears that, roughly half of all interest calculations from rounding down will be have the depositors penalised 1 sen and the money skimmed off somewhere. The other half (like you this time) won't get any extra from rounding up, but this is not too bad as not expecting bank to pay extra. It is probably just a program way or bug - whether Affin internal auditors knows about it or how it accounts for the difference - who knows??
In the case of Affin Bank, the final amount is not printed for the FD I had, but for Affin Islamic Bank, the final amount is printed on the FD cert. like Bank Rakyat. The total interest to be paid is printed out at UOB and Bangkok Bank.
