now all special jar already stated 5 days left and 3.6%.
so i think it's official now.
10 Jan onwards, lower rate 3.3%

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)

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...

I rechecked the FAQ links and T&C PDF, nothing changed. Check their FB page, 3.3% and 3% mentioned:

https://www.facebook.com/myboostbank/

Not sure where you saw the 3.3 and 3.4% thingie, if it's from the app notification, just ignore. As I said, their app figures are all wrong until things have settled down. Always check the FAQ, T&C PDFs and their social media pages.

T&C no change. DSA 2.5%, Normal + Celebration saving jar 3%, Special jar 3.3% is what we know so far.

Didn't receive any special amount on 3.4% lol 

But I got this for the first time:

only new account. dont see it on iphone

doesnt appear for me

https://myboostbank.co/promotion/sip-save-g...-and-zus-coffee

and need buy zus once a month to unlock it

how come old boost bank acc can see zus jar????

in May 5 i wanted to Duitnow RM800 to TnG but failed facial recognition. so i had to use debit card topup to send it over.

so from then onwards, my daily interest is RM0.06 instead of RM0.01 (so I see RM73.06 daily. this is normal behaviour as i encountered this during last year's 5% cashback promo. i used debit card to reload into tng to get the cashback, and i also see the same extra interest as the money is considered "floating")

today, i found out that i have extra RM800 in the boost acct. tried to search boost trx on May 5th and 6th and it seems like that debit card trx has disappeared. so woohoo RM800 windfall?

my boost beyond card also, get free RM1k few month ago...

it is useless. just close bank acc and move on to those stable

rize also higher interest. however one big disaster last year coz thousand of people money lost during transit. Took more than 10 days+ to recover the money & some account has negative balance. Trust lost and a lot of people move away even higher interest.
Boost bank CS is very bad when u have a problem. One email to them, end up 3-4 email from them which keep asking same question about you. For me it sound stupid, just 1 email to verify is enough. Waste of resources and inefficient when dealing customer problem. 1 simple problem, drag for a week. Not case resolution, but keep asking info about you.

Stability + Good CS is crucial when deal with digital bank. It is not a physical bank which you can knock in their door.

If above don't meet & give high interest also pointless as digital bank. Compare to current digital bank ranking, i will rate

1.GXbank & Aeon Bank
3.KAF (Beta)
4. Boost Bank (last)

no need pay fees? using them for a years+ to get boost coin multiplfy

it is UT. so not fix. same like versa. that why if want guaranteed, then digital bank 3.3% or 3%

Bro..did you notice the 'note' section below?

exactly...how can the system do this by itself

saving jar, not special jar
