Sorry, BoostBank kept changing rates here and there within one day, my calculations can't keep up and I made some mistake in the earlier calculations; Optizorb corrected it, thanks! And from what I check a moment ago, they insert wrong URLs for the T&C of all Sabah jars: try to click on the T&C links for the Sabah jars and they will show the celebration jar T&C instead  Go check out: myboostbank.co/special-jars

Anyway, here's what we know so far:

2.5 % p.a. DSA (no deadline announced):

Minimum 0.005*365/0.025 = 73, at increment of 0.01*365/0.025 = 146 for every extra cent of interest (no max limit *, 50k daily transfer limit cap)

3.2 % p.a. Normal saving jar (no deadline announced, but suspect all saving jar rate will drop to 3% after 9th January, in line with the declining rate for Celebration jar after 9th January):

For now:

Minimum 0.005*365/0.032 = 57.04, at increment of 0.01*365/0.032 = 114.07 for every extra cent of interest (Normal jar max limit is 1 million, but to earn interest, max needed is just 57.04 + 114.07 * 8766 = 999,994.66 per jar, uhmmm let's push it further, since we will get 999,994.66 * 0.032/365 = 87.67 per day at this juncture, might as well target 87.665 per day right? Hence, the maximum principal to put in is 87.665*365/0.032 = 999,928.91.

Rate drop to 3% after 9th January (same with Celebration jar, see below, except deposit limit -> normal saving jar limit 1 million, Celebration jar limit 25k):

Minimum 0.005*365/0.030 = 60.84, at increment of 0.01*365/0.03 = 121.67 for every extra cent of interest (Normal jar max limit is 1 million, but to earn interest, max needed is just 60.84 + 121.67 * 8218 = 999,944.90 per jar, uhmmm let's push it further, since we will get 999,944.90 * 0.03/365 = 82.19 per day at this juncture, might as well target 82.185 per day right? Hence, the maximum principal to put in is 82.185*365/0.03 = 999,917.50.

3.6 % p.a. Special saving jar (3.6% only till 9th Jan 2025, from 10th Jan onwards Celebration/birthday jar rate dropped to 3% p.a., CelcomDigi rate dropped to 3.3% p.a., Sabah jar T&C not yet released...):

From now till 9th January 11:59:59 pm:

Minimum 0.005*365/0.036 = 50.70, at increment of 0.01*365/0.032 = 101.39 for every extra cent of interest. 25k limit max principal is 24,992.37 (you earn 2.47 MYR daily interests) while for 50k limit max principal is 49,934.03 (you earn 4.93 MYR daily interests).

From 10th Jan 12 am onwards:

3% Celebration/Birthday jar magic number follows the case mentioned above in normal saving jar paragraph

3.3% CelcomDigi and the Sabah jars:

Minimum 0.005*365/0.033 = 55.31, at increment of 0.01*365/0.033 = 110.61 for every extra cent of interest (I will leave it as an exercise for you to show that for the 50k CelcomDigi jar, if you are eligible, the max principal to put is 49938.64 and you get max daily interest of 4.52 MYR.)

* after credit transfer verification, max across all balance including saving jars: RM 100,000,000, see https://myboostbank.co/terms-and-conditions section C, item 3)

Wah bro you calculated till so big near RM1 million..?

by the time you deposited that amount the extra 0.01sen is really insignificant

for those who really wanna squeeze the max you should only place bare minimum eg  RM73 ,RM57.04 only in each jar

if you have few hundreds the benefit is very much diluted
if few thousands there, the effect become insignificant

go into few hundreds k, no need this anymore

That's for the super calculative ones.   

As Wall Street says, you gotta be "efficient". Every cent counts yea.

guy3288 just calculate as theory exercise only.

honestly if 3.0%, practically just put into KDI save only. put emergency daily cash into Boost + magical numbers RM0.005 round up

even i've that much money, i dare not to put in Boost due to poor CS + unstable app.. better put to proper bank instead of digital bank for now until all stabilize...

anyway, start tomorrow either boost or aeon. both same so 50% on each

I guess a lot of people are moving their money out.
