To further enhance this info:

Android users update your BoostBank app.

Guys, the special jar interests dropped to 3.6% p.a. starting from this month (December)

No more 4% p.a. liao

T&C updated: https://myboostbank.co/sites/default/files/...ars%20T%26C.pdf

Time to move 1006.50 to GX Bank again.

New magic numbers:

2.5% DSA: 0.005*366/0.025 = 73.20 (subsequent topups to earn 0.01 MYR interest @2.5% p.a. = 146.4)
3.2% normal jar: 0.005*366/0.032 = 57.19 (subsequent topups to earn 0.01 MYR interest @3.2% p.a. = 114.38)
3.6% special jars (including Sabah jars): 0.005*366/0.036 = 50.84 (subsequent topups to earn 0.01 MYR interest @3.6% p.a. = 101.67)

Let me add more info for those who wish to max up the BoostBank special jars.

Magic numbers from tomorrow (1nd Jan 2025) till 2nd January 2025:

2.5% DSA: Minimum 0.005*365/0.025 = 73, at increment of 0.01*365/0.025 = 146 for every extra cent of interest
3.2% normal saving jar: Minimum 0.005*365/0.032 = 57.04, at increment of 0.01*365/0.032 = 114.07 for every extra cent of interest
3.6% special saving jar: Minimum 0.005*365/0.036 = 50.70, at increment of 0.01*365/0.032 = 101.39 for every extra cent of interest

Got 3 post/12 hours limit, gotta condense things a bit here.
So now we know the 2nd January 2025 ending period for the previous promo is nonsense. They can change the rate and ending period as they like. The T&C is designed to protect their interest, not yours and mine 

New magic numbers (for the next 6 months... Now they say the 3.3% special rate will last for 6 months, let's see...):

2.5% DSA: 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% normal saving jar: Minimum 0.005*365/0.032 = 57.04, at increment of 0.01*365/0.032 = 114.07 for every extra cent of interest (max limit is 1 million, but to earn interest, max needed is just 57.04 + 114.07 * 153 = 995,502.58 per jar, uhmmm let's push it further, since we will get 995,502.58 * 0.032/365 = 87.28 per day at this juncture, might as well target 87.275 per day right? Hence, the maximum principal to put in is 87.275*365/0.032 = 995,480.47)

3.3% special saving jar: Minimum 0.005*365/0.033 = 55.31, at increment of 0.01*365/0.033 = 110.61 for every extra cent of interest (max 25k for all jars excluding CelcomDigit jar's 50k. For 25k max limit case, max principal needed is 55.31 + 110.61 * 225 = 24,942.56. Let's do it again, we will earn 24,942.56*0.033/365 = 2.26 interest per day per special jar. We apply round-up trick one more time: max principal to put in = 2.255 * 365 / 0.033 = 24,941.67. 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. 

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

Feel free to correct me if any of the figures above are wrong.
Last year, our friend asked if PIDM covers saving jars as well. I dug in to the T&C walls of text and found this:

Beware of their ridiculous marketing. 3.79 % is earnings rate, you need to minus Management Fees (-) 0.5% per annum and Trustee Fees (-) 0.025% per annum to get 3.265 % p.a.

Most banks and fund houses advertise the final post-all-in-expense interest rate, Boost does not...  Kindly see: myboost.co/feature/boostmymoney (scroll down, FAQ item 7: What is "Earning Rate"?)
