Bro, for the GIA-i issue that few of us encountered, it is NOT due to the 366/365 days issue. We know how to calculate based on 366 days. Maybank is using 366 days for this year.

Your GIA issue could be it did not changed from 4% to 4.5% from 7th month on.

MBB did NOT change from using 366 days to 365 days.

Yeah I saw y'all post about them not adjusting 7th mth onwards so I went to check lor. But shit, the diff was few sen, so I did not crunch the numbers in fine detail. Lemme check again. But one thing lar.... the discrepancy DID NOT happen only for the crossover mth iirc. Anyhow, will check with microscope again . TQ

Bro, for my case, MBB has admitted the error. They are manually crediting the interest to me. For May month the extra is >RM15. Not small neither big. By 12th month, the difference total is RM185.

Sorry, I looked and searched, can't seem to locate any earlier answer:

MBB GIA-i, "Rate as declared on maturity date" 

Does it mean the rate is only known when you uplift? So perhaps less than 12 months might be better in these volatile times?

Same tax regulations for this type of FD? 

If compounded, added to principal, is it about the same as the eFD 2.0 ?

Sorry, I looked and searched, can't seem to locate any earlier answer:

MBB GIA-i, "Rate as declared on maturity date" 

What does this rate refer to or affect? Is it the redemption rate ie on principal?

I get the impression from those who have been using GIA for short term "pocket money" that they get back their principal sum at 100%. Is that what u are referring to? I was also concerned because i remember they say something like redemption of the units at manager's quote/rate on redemption date (what I remember only & maybe not their exact words)

OK boss bbgoat, I checked mine already. For my case lar, dunno about urs, I was given 4.5% in May based on 366 days on the dot ie calculations to the dot.

For  Jan 2016, I got 4%. But the base was using both 365 days and 366 days because I placed the deposit on 25th of the month ie 6 days for 26/12/2015 to 31/12 on 365 days base and 1/1/2016 to 25/1/2016 on 366 days base. The calculation was out by 1 sen only this time.

Up to you lar. If you happy, then    Else, you can check calculations like I did.

Then again, different branch may work differently... heaven knows how Maybank actually work. Also I haven't checked if they gave me any credit in June

btw, your 15 for 31 days in may at 0.5% interest diff tells me that your principal  is about 35big ones, right? If correct, then your branch actually did not change to 4.5% in 7th month. Mine did. Which tells me that is driven by branch

If you want, can PM me your start date, principal and what u actually got credited for Jan 2016 & I can do the calculations for you

i thought e GIA-I interest calculated daily and deposit into ur savings acc once u did withdraw? hmm...

Bro, u miss out post talking about this issue few weeks back. The 7th mth 4.5% issue is NOT related to branch. One other forummer who has more than 1 placement on the same day said one of the placement on the 7th mth received 4.5% while another one received 4%. It is due to the coding error that the counter done wrongly in the MBB system.

As I said MBB has acknowledeged their error. Groups of people from my branch affected but probably some or most do not know unless they do the calculation and check the monthly interest.

The amount I placed is RM37k.

Thanks for your offer. I have been calculating the monthly interest exact to the last 3 digit of decimal points. 

is the adjustment interest amount = 1 day interest?

Are you refering to eGIA-i or the GIA-i?

sorry to ask... i only went for the 4.5% effective rate offer last Oct. Is that GIA-i? Is eGIA-i the online version giving 4% now? If I go to counter now, can still get GIA-i? I don't expect 4.5% lar... got 4% also? TIA

For STEP-UP type FD promotions, the effective rate quoted is a simplification. The actual effective rate depends on the particular month and whether you placed on the 29, 30 or 31.
ACTUAL accurate effective rate is the sum of the interests for each step period (number of days in step period / 365 x % step rate /100 x principal) divided by principal and multiplied by 365 / total number of days.
The SIMPLIFIED inaccurate effective rate used by the banks is calculated as if all the months have the same number of days, and the date near the month end does not matter at all.  imho, banks cannot tell us our true effective rate unless they know exact date of the placement. you are right to assess it based on the total
For Maybank, the divisor is 365 or 366 depending on which year is involved for the December and January portions.
For those who qualify or get monthly payment of interests, you need to take into account that the bank needs to pay each month for those who did not avoid the 29, 30 and 31.
As for problems with rounding treatments, the simplest way out is to choose a multiple of 365 (or 366 for Maybank in 2016 tenor) which will give a fixed amount per day. For example Affin, rate 4.5%, principal 36,500, will give interest of 4.50 per day. Note that this calculation trick can work for any length of time except at Maybank on a leap year.
